Mercedes EV drivers with a bad case of range anxiety might want to stock up on Ambien, now that the automaker is warning them not to charge their cars to full. The German brand has instructed owners of certain electric SUVs to limit charging to 80 percent because their cars could suffer what engineers term a “thermal event.”

In other words, a short circuit of the battery cells might result in a fire, and we’ve all seen enough videos of EV infernos to know they can be devastating, and extremely difficult to put out.

Fortunately for Mercedes and its owners, this issue only affects a relatively small number of cars. Just 169, to be exact, including 100 EQB 300 4Matics and 48 EQB 350 4Matics. Both are dual-motor EVs, but the recall also concerns 21 owners of the single-motor EQB 250.

Previous Form

And while the scope of this safety campaign is small, some of you might remember that the brand previously recalled over 7,000 of the SUVs in the US early in 2025 due to a fire risk. In that case Mercedes issued the same guidance about not charging past 80 percent until the fix – a software update – was applied.

All of the newly-recalled EQBs are what Mercedes calls “early-stage” MY22-23 vehicles, the automaker claiming that batteries fitted to later EQBs are more robust, and not caught up in the recall.

It also says that while owners of the 169 EVs that are affected will probably receive dash cluster warnings if things were hotting up under the floorpan during drives, a parked EQB could light up with no warning.

So if these early EQBs have less robust batteries, Mercedes must be swapping them out for newer ones, right? Apparently not. Instead owners will get a simple software update, although it’s one that still requires a trip to a Mercedes service center early in 2026.

Short-range Missile

The EQB 350 was only rated for a miserable 227 EPA miles (366 km) with a full battery, so restricting charges to 80 percent would bring the max range down to around 180 miles (290 km).

Factor in the need to leave a safety margin at the ‘empty’ end of the battery charge indicator and you could be looking at 150 miles (242 km) between fills. Let’s hope your relatives live nearby, or that you’ve made peace with spending part of the holidays loitering at freeway charging stations.

Two months after the NHTSA opened an investigation into thousands of Rivian’s all-electric delivery vans, the carmaker has announced a recall impacting almost 35,000 units.

Rivian says that on certain examples of the EDV, the driver’s side seat belt pretensioner could be damaged from repeated misuse. It notes that misuse could include the driver sitting on the seat belt while it’s buckled underneath them.

If the pretensioner cable is damaged, it may not adequately restrain the occupant in a crash, increasing the risk of injury.

While Rivian notes that “a damaged pretensioner may be visibly detectable to the driver in some cases”, it presumably won’t be noticeable in others. Even so, the carmaker says it is not aware of any accidents or injuries related to the issue.

The initial probe, launched by the NHTSA’s Office of Defects Investigation, involved 17,198 examples of the 2022 and 2023 model year Rivian EDVs. However, the recall also impacts 2024 and 2025 models. All of them were manufactured between December 10, 2021, and November 8, 2025, and a total of 34,824 units are affected.

According to Rivian, it has already released an over-the-air update that enables automatic detection of driver seat belt misuse and has committed to inspecting and, if necessary, replacing the driver’s seat belt pretensioner assembly at no cost. It will also reimburse any owners who have paid out of pocket to fix the issue.

Rivian initially developed the EDV exclusively for Amazon, with the retailer placing an order for 100,000 examples, all of which are scheduled to be delivered by 2030. However, it’s now also available to other companies and sold as the ECV, or electric commercial van.

Sometimes, the fix really is the obvious one, especially when the original solution involved little more than strong glue and wishful thinking. Tesla has outlined how it intends to keep the Cybertruck’s optional off-road lightbar from slipping away.

Instead of relying on adhesive, which has not aged well in practice, the company now plans to fasten the light bar to the roof with actual bolts.

Last month, Tesla announced that it was recalling 6,197 Cybertrucks because the optional LED light bar was being held on solely with strong adhesive.

Not surprisingly, several light bars failed to stay attached, separating from vehicles while driving. The issue stemmed from problems with the adhesive primers used during installation. So far, Tesla has logged 619 warranty claims related to the light bar coming loose.

Bolts Sure Are Better Than Adhesive

Well, at least now Tesla has come up with a solution that should, in practice, work. The company has developed a new steel bracket that affixes to both sides of the light bar.

The bracket then slides between the stainless steel window frames of the Cybertruck and includes a small attachment that is bolted directly into the vehicle’s roof.

Although Tesla has now developed the fix, it’s not yet ready to start repairing customer cars. According to the original recall bulletin, owners won’t be formally notified until December 26. That means service center appointments likely won’t begin until early 2026.

So, if you own a Cybertruck with the light bar held on exclusively with adhesive, it might be wise to limit your drive. Or, if you must drive it before you’re able to book in an appointment at your local Tesla service center, it wouldn’t be a bad idea to get some duct tape to try and better secure the light bar, if only temporarily.

A Long-Standing Issue

The off-road light bar has been a sore point for owners ever since the Cybertruck arrived in late 2023. Owners who paid extra for the Foundation Series version of the electric pickup were supposed to receive the light bar as standard, yet most trucks showed up without it because Tesla was still finalizing the accessory.

By August, the delay had worn thin enough that one owner took the matter to court and sued Tesla in California.

Structural adhesive is incredibly powerful, but using it correctly requires very specific steps. When those steps aren’t followed, the adhesive can turn out to be practically useless, as Cybertruck owners are finding out the hard way.

In fact, as of this writing, Tesla knows of at least 600 of them who have had their glued-on light bar come loose. As a result, it is recalling almost 6,200 trucks.

According to a new filing with the NHTSA, the optional LED light bar affixed to some Cybertrucks could be problematic.

We’ve covered how technicians install these things in the past, and it’s not with nuts, bolts, or screws, but an adhesive that requires a primer to go on before the light bar. If this job gets done wrong, the light bar could fly off in traffic.

Over 600 Warranty Claims

Tesla told regulators that it knows of 619 warranty claims surrounding this issue. It also knows of one field report where this primer and adhesive situation might be to blame. Thankfully, as far as it knows, it hasn’t led to any accidents or injuries.

The automaker says it comes down to technicians inadvertently swapping between two adhesive primers, BetaSeal and BetaPrime, during installation. Despite multiple service bulletins and manual updates, the mix-ups kept happening.

The remedy sounds as if Tesla is going to keep things simple. Service centers will inspect the light bar and either retrofit or replace it with one secured by a “positive mechanical attachment” along with adhesive tape.

Based on that, it sounds like they’re going back to real nuts and bolts to help ensure this won’t be a problem again. We couldn’t find any diagrams of the remedy, but that’s not too surprising given how fresh this recall is.

Owner notifications won’t even go out until the day after Christmas, according to Tesla. Between now and then, it seems wise to check your light bar if you happen to have a Cybertruck with one.
