Maintaining your own car has long been a badge of pride for some and a financial necessity for many others. Swapping fluids, filters, or brake pads is part of the standard weekend maintenance ritual for countless drivers.

But for one Hyundai Ioniq 5 N owner, that sense of self-reliance recently hit a wall, or more precisely, a brake caliper. He discovered that replacing the rear pads on his EV wasn’t as simple as it used to be. Now, Hyundai has responded.

It might seem odd that someone has already burned through their rear pads, especially on an EV, but it happened because the owner drove this car the way Hyundai wants owners to: hard and on the track.

When he tried to replace these pads, he learned that he needed to retract the electronic parking brake. That’s where this easy DIY job took a scary turn.

When Maintenance Gets Complicated

One way to retract the brake is to use Hyundai’s Global Dynamic System (GDS). That software and the hardware that goes with it can cost almost $6,000, as we’ve seen online. Don’t worry, though, there’s another option called the J2534 Diagnostic Tool, which Hyundai supports, as seen in an official document discovered by TheDrive.

According to the owner, Redditor u/SoultronicPear, the software costs $60 a week (or less on average for longer time periods) and requires the use of a J2534 adapter that can be found for around $2,000.

Hyundai currently approves only three options for this tool: the CarDAQ Plus 3, Bosch’s MTS 6531 and DG Technologies’ d-briDGe PRO, adding that, “under no circumstances do we recommend the use of a
non-approved J2534 device”. So be warned.

Credentials Required

More importantly, beyond that, using the tool requires special National Automotive Service Task Force (NASTF) authentication and a constant internet connection.

But here’s the kicker. Only certified repair shops or repair businesses are supposed to get access to that software. NASTF told the owner that “NASTF credentials are for use by qualified technicians, mechanics or locksmiths working in businesses providing repair or replacement services.”

Hyundai Speaks Up

Before publishing our first coverage of this issue, we reached out to Hyundai for comment. After the story went live, the automaker responded with the following statement to Carscoops:

“Hyundai is committed to supporting both our dealer network and independent repair facilities with safe, secure, and accessible service solutions. For vehicles equipped with electronic parking brakes, including the Ioniq 5 and Ioniq 5 N, the official repair procedure requires placing the rear calipers in service mode using either our Global Diagnostic System (GDS) or the J2534 application.

This ensures proper functionality and customer safety. Hyundai recently expanded access through an update to our J2534 application, enabling aftermarket users to perform functions previously restricted by the GDS secure gateway.

While authentication through NASTF is required for sensitive operations, this step helps maintain security and accountability. Our official dealer tool (GDS) is also available for purchase by anyone. Hyundai is actively exploring ways to make routine maintenance easier for all customers while upholding safety standards.

We appreciate the interest in DIY repairs and will continue working toward solutions that balance convenience with security.”

Seeking more detail, we pushed Hyundai to clarify whether a skilled owner could realistically do the job at home. The company followed up with this explanation:

“DIYers can replace brake pads on the Hyundai Ioniq 5 and Ioniq 5 N, but it requires specific steps and tools. Because these vehicles use electronic parking brakes, the rear calipers must be placed in service mode using either Hyundai’s Global Diagnostic System (GDS) or the J2534 application with a compatible pass-through device.

Both tools are publicly available, though GDS is more expensive and J2534 requires NASTF authentication for secure functions. Without these tools, the job cannot be done safely, as manual retraction could damage components.

Hyundai is not restricting DIY repairs, in fact, recent updates have expanded access, and we continue to explore ways to make routine maintenance easier while maintaining safety and security.”

---

So, yes, it can be done. But unless you already own the specialized tools or have deep pockets, the process can cost about as much as a tired old hatchback from the classifieds.

For now, at least until a cheaper workaround surfaces (we’re looking into it, so stay tuned), the Ioniq 5 N’s rear brakes may remain one of those maintenance jobs probably best left to the professionals.

We all knew that sales of EVs in the US would fall dramatically in October, since there’s no $7,500 federal tax credit available. However, major automakers like Hyundai and Kia may not have anticipated just how dramatically sales would fall due to this policy change.

Starting with Hyundai, it recently confirmed that it sold 70,118 vehicles last month, a 2 percent decline from the 71,802 in October 2024. Importantly, year-to-date sales are up 10 percent to 748,467. But this is where the good news mostly ends.

Sales of the Ioniq 5 plummeted 62 percent to just 1,642 units, down from 4,498 sold last October. Similarly, Hyundai sold 52 percent fewer Ioniq 6s, down from 837 units to 398. The Ioniq 9 wasn’t available last year, but it hasn’t been a big seller this year, shifting 4,494 units year-to-date and just 317 in October.

Other Hyundai models that experienced significant declines included the Kona (-13 percent), Santa Cruz (-29 percent), Sonata (-32 percent), and Elantra (-16 percent). Helping to prop up total sales were the likes of the Palisade (+6 percent), Santa Fe (+22 percent), Tucson (+16 percent), and Venue (+49 percent).

Kia’s EV Collapse

Things are similar at Kia. Year-to-date, it sold 705,150 vehicles, a solid increase from the 653,078 units moved over the same period in 2024. Its total sales also rose slightly in October from 68,908 units to 69,002. However, like Hyundai, Kia EVs didn’t share in this success.

Kia sold just 666 examples of the three-row EV9 this October, over 1,941 examples sold the same month last year. Overall sales of the EV9 this year are down from 17,911 to just 13,114. Then there’s the EV6, which saw its number fall from 1,732 to just 508.

Through the first ten months of the year, 11,585 EV6s have been sold compared to the 17,717 last year. Kia also sells the Niro as an EV in the US, but has grouped its sales with those of the gasoline and hybrid versions.

These numbers come just after Kia confirmed that it has postponed the American launch of the EV4 “until further notice” due to changing market conditions.

Automotive enthusiasts aren’t the only ones who enjoy getting their hands dirty. Many regular drivers tackle oil changes, swap air filters, or fit new brake pads without a second thought. These are the sorts of jobs that make you feel connected to your car, a small ritual of maintenance and pride.

But every so often, a manufacturer decides to make things harder than they need to be. I once had to drop an entire subframe on my BMW just to replace oxygen sensors, an experience that left me wondering whether the engineers had ever tried it themselves.

It’s rare to see a mainstream brand like Hyundai put similar hurdles on its customers when it comes to repairs. However, according to one owner, the brand isn’t just making a simple fix hard; it’s straight up declaring war on his (and your) right to repair his own car.

Is Hyundai Denying Right to Repair?

Two recent posts on Reddit’s r/Ioniq5N community have ignited a fierce debate. There, an owner claims Hyundai has drawn the battle lines. He’d set out to replace his rear brake pads, something he says he’s done countless times before on other vehicles, but soon discovered the automaker’s diagnostic tools had other plans.

According to the post, Hyundai’s digital systems effectively lock out anyone who isn’t a certified technician from performing even basic maintenance.

The rear brake pads are affected by the electric parking brake. To replace them, one must disengage the brake and get it to retract completely, otherwise, the new pads won’t fit. In addition, the car needs a diagnostic tool to recalibrate the motor on how far to move with the new pads in place.

In other words, even if you could manually disengage the parking brake, the car would still need calibration to work properly.

The only way to accomplish this is allegedly to use Hyundai’s J2534 Diagnostic Tool, a Windows-based application available only through the automaker’s tech info portal.

The owner says the software requires a $60 weekly subscription, a $2,000+ approved hardware adapter, and a constant internet connection for authentication. Even then, it reportedly doesn’t work properly on newer models like the 2025 Ioniq 5 N.

No DIYers, Please – Only Pros

“I broke down and bought the subscription and special adapter,” the owner wrote. “Guess what? It didn’t work.” Only later did they find out why. “My blood is boiling at the moment. NASTF has blocked my account, saying “DIYers are not permitted access.”

They included a photo of a message from NASTF that says in part, “Please provide your business name and 9-digit Federal Employer Identification Number. DIYers are not permitted access.”

The irony, the poster points out, is that Hyundai dealers don’t even use this Windows tool. They reportedly have access to an entirely different Android-based software suite that works seamlessly.

While this all sounds like a bureaucratic mess, the underlying issue raises serious questions about Right to Repair access in the EV era. For decades, enthusiasts and independent mechanics have fought for access to diagnostic tools and repair data that manufacturers often guard tightly.

But when basic wear items like brake pads require proprietary authentication, the argument takes on a new urgency.

Has Hyundai Gone Too Far?

Nothing about this setup sounds reasonable. Replacing brake pads is as fundamental as car maintenance gets, yet Hyundai’s system allegedly makes it feel like breaking into Fort Knox.

If that’s true, the automaker has some serious rethinking to do because locking out the people who care most about maintaining their vehicles isn’t a good long-term strategy.

I have personally considered buying an Ioniq 5 and a Kia EV6, but will avoid both until this sort of thing is doable for folks like me. Hyundai tells us that it’s looking into the situation and will report back once it has more information.

For all the talk about market forces shaping the car industry, it still seems that government incentives are doing most of the heavy lifting for electric vehicles. Or at least they were, until the end of September, when the federal tax credits officially ran out.

As much as 90 percent of all battery-electric and plug-in hybrid vehicles sold in the United States through the first nine months of the year are believed to have benefited from some form of tax credit, according to market research firm Rho Motion.

A Surge Before the Deadline

The end of the federal EV tax credit on October 1 set off a nationwide rush for qualifying models, driving record sales for several brands and pushing overall EV demand to new highs in August and September.

This year, the EPA determined that 20 battery-electric vehicles and a single plug-in hybrid model were eligible for the New Clean Vehicle Credit, valued at up to $7,500. These vehicles together accounted for 55 percent of all EV sales from January through September.

Leasing Loopholes and Fleet Boosts

Of equal importance in propping up sales was the lesser-known Qualified Commercial Clean Vehicle Credit, also valued at up to $7,500.

This credit was available for vehicles weighing less than 14,000 lbs and aimed at fleet and business buyers. This is also the credit that allowed car manufacturers to claim the tax credit themselves, and then to reduce the lease price on new vehicles.

Notably, leased passenger cars and trucks were not subject to the same sourcing and assembly requirements as purchased vehicles. They also didn’t need to be built in North America, which made leasing an especially attractive option for both manufacturers and buyers.

As the September 30 axing date for the credits drew closer, sales of electrified vehicles surged across the United States. As noted by Rho Motion, Ford sold 30,612 battery-electric vehicles in the third quarter, a huge 86 percent increase from Q2.

Additionally, GM’s BEV sales jumped 44 percent to 66,501 units. Tesla also reported a 27 percent sales increase, and Hyundai also enjoyed substantial growth, thanks to a more than doubling of demand for the Ioniq 5.

What Comes After the Incentives?

It remains to be seen how sharply BEV and PHEV sales will dip in the fourth quarter now that the tax credit has ended. Rho Motion expects demand to “decline sharply.”

The research firm also points out that tariffs, high local manufacturing costs, and relaxed fuel efficiency standards are likely to deter investment in domestic EV production, creating further pressure on demand in the months ahead.

The Hyundai Ioniq 5 N is a game-changer. It proved all on its own that electric cars can deliver genuine driving enjoyment, not just straight-line speed. No doubt, that’s partially what convinced one Texas buyer to snap up one of the very first examples available in the state.

The excitement behind the purchase has soured, though, because at the 8,000-mile mark, the Ioniq 5 N allegedly failed. Now, it’s reportedly been sitting at a dealership for two months straight with no end in sight.

The public saga began on August 27 when the owner, William, posted about his situation on Reddit. In a thread with the title “Help me navigate the run around I think I am getting from service,” he details how one day his car displayed a red warning light and refused to charge.

At that point, the car had already been in service for weeks “with no clear answers,” he says. Notably, the service advisor reportedly told him the issue wasn’t the ICCU, or Integrated Charging Control Unit, the system that controls charging and power flow in the car and has been a known weak spot on some Ioniq 5 models.

Shared Frustrations

Other Reddit users claiming to own Ioniq 5 N or Elantra N models described similar frustrations with the same dealer in San Bruno, California. One said their car was misdiagnosed before ultimately receiving a new ICCU after 45 days.

“They are an absolute mess over there,” another commenter added about the same Northern California dealership. A week ago, William posted another update.

“After 2 months, I still don’t have my car and no end in sight. Good luck to folks out there waiting on a battery”, he wrote. In a screenshot from the dealership, a service advisor reportedly confirmed that the vehicle’s main battery was “on backorder” with “no ETA.”

Communication Breakdown

William went on to tell Carscoops that Hyundai’s lack of transparency has been the most frustrating part of the process. “Even giving Hyundai the full benefit of the doubt on supply-chain issues, the lack of transparency is inexcusable,” he said. “Every week it’s the same line – no ETA on a battery and no ETA on my car.”

The owner, who has already initiated a buyback request, says that process has also stalled: “Four weeks in, and no progress.” Carscoops has reached out to Hyundai for comment regarding the reported battery issue and ongoing parts delays.

The automaker confirmed that it is looking into the issue as of this writing, but hasn’t provided any additional insight at this point. We’ll update you here if we hear back.

Electric vehicle shoppers are waking up to a new reality. With the federal EV tax credit now gone, many models have effectively become $7,500 more expensive overnight, whether bought outright or through the once-reliable lease loophole.

To soften the blow, several manufacturers are getting inventive, introducing aggressive discounts, cheaper trims, and in some cases, cutting slow-selling models altogether.

The end of the tax credit on September 30 led to a significant surge in EV sales across the United States; however, sales are expected to decline through the final quarter of the year. In a bid to try and prop up demand, Hyundai is offering a cash incentive worth up to $11,000 on the 2025 Ioniq 5.

Automakers Get Creative

Both General Motors and Ford have also been looking for ways to encourage shoppers to pick up the keys to one of their models.

For example, GM had been working on a plan for its lending arm to initiate the purchase of EVs at dealership lots and then apply for the $7,500 federal credit, rolling this money into lease terms for customers. However, it recently scrapped these plans, reports Reuters.

Nevertheless, it shows how creative some firms are getting to try and ensure EV sales don’t fall off a cliff. This week, Tesla also introduced lower-priced versions of the Model 3 and Model Y.

While both of these models were in the works before the Trump administration confirmed that the credit would be axed, they may help to convince some shoppers to buy an EV who would have otherwise been priced out of the market.

According to Ivan Drury, director of insights at Edmunds, automakers are taking varied approaches to a common problem.

“The overarching message of tax credits going away for EVs has had a very different set of approaches from each automaker,” he told Business Insider. “Which approach will be most successful? Debatable. Nobody’s looking to increase. That’s cuckoo talk at this point. You just want to maintain that basic level of sustainable sales, and this is the different methodologies that each of them have taken.”

Some brands have decided that cutting losses may be the most practical move. Both Stellantis and Acura have opted to discontinue certain EV models altogether. Acura recently confirmed it will pull the plug on its all-electric ZDX SUV, while Stellantis has shelved plans for the RAM 1500 REV.

It’s yet another reminder that even in an age of electrification, not every experiment makes it through the market’s growing pains.

It’s no secret that government incentives have played a huge role in fueling America’s appetite for electric vehicles. Without them, enthusiasm tends to cool fast.

So it’s hardly shocking that many former EV owners say they’d consider returning to battery power only if a generous incentive were back on the table, according to a recent study from The Harris Poll.

Read: Expiring EV Tax Credit Sent Tesla Sales Into Overdrive But Its Flagships Crashed

The survey, conducted between September 23 and 25, included responses from 2,095 adults across the United States. Of these, 1,675 participants, or about 80 percent, said they plan to buy or lease a new or used vehicle in the future. Within that group, 485 respondents, roughly 29 percent, said they were extremely or somewhat likely to choose an EV.

What Would It Take?

Among respondents who had previously owned or driven an electric vehicle but later switched away, 60 percent said they would need an incentive of at least $5,000 to consider returning to an EV.

A further 30 percent said they would need an incentive of between $2,500 and $4,999 to reconsider, while 11 percent said they would be willing to accept an incentive of less than $2,500.

Senior consultant at The Harris Poll, Greg Paratore, acknowledged that affordability remains the top concern for 64 percent of EV buyers.

Automakers Step In

While the removal of the new and used EV tax credit will impact demand for electric cars, Paratore noted that automakers could use the removal of the credit to build extra trust with consumers by helping to share the added cost burden.

For example, Hyundai recently announced it’s cutting prices of the 2026 Ioniq 5 by a significant $9,800 in the wake of the tax credit’s removal. Additionally, Hyundai is offering a $7,500 cash incentive on the remaining 2025 Ioniq 5s that it has in its inventory.

Meanwhile, Ford chief executive Jim Farley warned that EV demand in the U.S. could tumble by as much as half due to the tax credit’s removal. If that happens, electric vehicles could see their market share shrink to around 5 percent, a figure last recorded in 2022.

Hyundai sales surged to record heights in the US last month, thanks in part to a significant increase in demand for its EVs and a few of its SUV and sedan models. And, despite the removal of the federal EV tax credit at the end of September, the Korean carmaker appears confident it can keep the momentum going through the rest of the year and into 2026.

In September, Hyundai sold a total of 71,003 vehicles in the US market, a 14 percent increase over the 62,491 sold the same month last year. In addition, Hyundai’s Q3 sales were up 11 percent to 678,349 units compared to the 610,494 sold through the first three quarters of 2024.

EVs Leading the Charge

Several models contributed to the surge in demand last month. The all-electric Ioniq 5 stood out, with sales soaring 152 percent from 3,336 units to 8,408. While many automakers saw a final bump in EV sales before the federal tax credit expired, Hyundai has moved quickly to soften the impact.

The company is now offering a $7,500 cash incentive on 2025 models, along with price cuts of up to $9,800 on 2026 Ioniq 5s. Year-to-date, sales of the Ioniq 5 have climbed 36 percent, from 30,318 units to 41,091.

Hyundai US Sales 2025

Elsewhere, sales of the Ioniq 6 have jumped 36 percent, although it remains a small blip in terms of Hyundai’s overall sales, with just 814 sold in September and 9,132 sold this year. The large, three-row Ioniq 9 sold 4,177 examples.

Demand for the small Venue also soared by 77 percent last month, with 2,836 finding new homes across the country. Hyundai reported a 28 percent rise in Santa Fe sales to 10,114 units. In September, sales of the Elantra increased by 23 percent.

There are some outliers in what has been a very good year for Hyundai. For example, year-to-date sales of the Sonata are down 5 percent to 45,914, Santa Cruz has fallen 18 percent to 20,633, and the Kona is down 11 percent to 57,278.
