MERCEDES-BENZ Complaints

The contact owns a 2017 Mercedes-Benz Sprinter 3500. The contact stated that while driving at an undisclosed speed, the front driver's side tire became deflated. The vehicle was driven to the dealer, where the contact was informed that the front driver's side rim was cracked. The contact was informed that the front driver's side rim needed to be replaced. The contact was informed that the parts were unavailable. The vehicle was taken to an independent mechanic, where the contact was informed that the failure had reoccurred due to potholes in the road. The vehicle was repaired; however, the failure reoccurred. The failure became a persistent failure. Additionally, the contact stated that the front passenger's rim and both rear rims were all cracked. In addition, the driver's side rear tire was damaged because of the failure. The contact stated that parts were unavailable at the dealer. The contact stated that during the failure, the contact had to search around for replacement rims.

My 2024 Mercedes-Benz GLE 350 unexpectedly braked on its own on two separate occasions while I was driving at a low speed, approximately 5 to 10 mph. There was no warning chime, no “BRAKE!” message, and no other warning immediately before the vehicle suddenly braked. One of the incidents occurred while driving through a drive-thru. The sudden braking was strong enough to jolt a properly restrained rear-seat passenger forward and caused discomfort around the waist area. I also received a dashboard warning stating “Active Parking Assist and PARKTRONIC Inoperative.” The vehicle was taken to an authorized Mercedes-Benz dealership, where it was inspected, scanned, test-driven, and a software update was performed. The dealership was unable to reproduce the unexpected braking and did not identify a confirmed cause for the braking incidents. The vehicle remains available for inspection upon request. I am concerned that this may be an intermittent safety-related malfunction involving the driver assistance, parking assistance, sensor, or braking systems because the vehicle applied the brakes unexpectedly without warning.

Electrical System malfunction with total electrical shutdown: Going in the street at about 35mph driven by a choffer and two passengers in the back seats , the right back seat passenger was using “relaxing massage”.controlled through the seat’s screen. The back seat”tablet” had a sign saying that the tablet was “ Over heated and it turned off. Seconds later there was a loud glass braking sound followed by a total electrical shutdown down and engene stall. All screens front and back turned off. The Right back passenger seat became extremely hot and a burning smell speared . The passenger on the hot seat had to Get out of the car. She was clearly in danger of burning. All lights including the door controls were off and the heaters ligh with its control were unusable. In about one minute later the burn smell started to subside and the car re-started on it’s own like all screens read “Maybach” and the users pictures appeared on the screens. The hot seat cooled on its own. We called Mercedes Service to report the incident. After about 10 minutes everything was normal. We made it home safe. The incident occurred around 3:40 pm so the car was taken to Mercedes of Coral Gables the following day. This Mercedes Dealer is literally accross the street from our apartment. The Chofer just crossed [XXX] and delivered the car at the service department. This was yesterday’s morning. They are revewing the car now..We have not heard from them. The passenger on the very hot seat was hot but she did not experience any burns. A couple of days earlier the car stopped “to avoid a none existing collision. There was no other vehicle in the street. This was also reported to Mercedes Service managet INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2025 Mercedes-Benz GLE450 4Matic equipped with Michelin Tires, Tire Line: Primacy Tour AS, Tire Size: 275/50/R20, DOT Number: 1B9RF011X0925. While the contact's wife was driving 55 MPH, the vehicle drove over a speed bump and the rear tires jumped away from the vehicle 10–12 inches. The vehicle was taken to the dealer. The contact was informed that the issue was normal for the vehicle. The contact was informed that there was no fix for the vehicle. The contact stated that the vehicle was a safety hazard. The manufacturer was made aware of the failure, and a case was filed. The contact requested a vehicle buyback, which was denied. The failure mileage was approximately 15.

While driving at 50mph, the vehicle came to a full stop in 2 seconds by auto breaking (to avoid collision) when there was no object or vehicle in front of the car. I almost got rear-ended as stopping from 50mph to 0 mph on a highway was extremely dangerous but luckily the car behind me was able to use the lane to my right to avoid the collision. When the vehicle was taken to the service center, the computer systems showed no record of this incident. However, I do have a dashcam footage of it. In the video, you can clearly see a stopped car on the left turn lane (the break lights of the car is visible and the car is stationary when the video is analyzed frame by frame.) The driving lane is curving to the right and the vehicle is also turning to the right following the lane. (this is verified by following the double yellow line - then the single solid white line and vehicle's motion to the right.) Despite all this, the car slammed the breaks and stopped. The video is seen by the service center workers as well. They updated the software on the car at the time of service. An escalated ticket was also created with Mercedes corporate office with case number: 23763407. At the very least, the cars should be keeping records of collision avoiding breaking administered by the car's system so when you're at the service center, there's a record of what happened. This incident could have resulted into a high-speed collision with severe injuries to the people in both vehicles and one pet. And if it did, the car would have shown zero record of functions performed and the drivers would have been blamed.

The seatbelt latch does not fully release when you press the red button. It needs to be wiggled and then it eventually does release. This is an ongoing issue.

Shock air leaking front right side. The car has 31,000 miles and is 5 years old. Is this to be expected?

I believe that my vehicle is subject to Recall Campaign # 21V197000. The vehicle is a 2016 Mercedes-Benz CLA250. I've had to have this part ( Front Stationary Roof panel) adhered 5 times in the last 10 months. Mercedes refuses to acknowledge the above campaign #. Not only is this a safety risk to my self and other drivers, there is risk of water damage any electrical components. When this issue was brought to their attention I was told this was VIN specific and no recalls were attached to this vehicle. The photos are from 2 separate incidents. There are no warning lights. My vehicle has had at least 2 unbiased inspections and available upon requet.

An inspection of my vehicle on August 6, 2026 disclosed that the rear subframe has corrosion, including perforation. It is my understanding that this problem has been identified in mine and many other Mercedes-Benz models, and that Mercedes-Benz has offered an extended warranty to replace the subframe in certain of these models, but my model for the year it was manufactured was not included. I was not made aware of this potential problem by Mercedes-Benz, and they are not offering an extended warranty to resolve this serious safety issue.

I request that NHTSA investigate whether 2023 Mercedes-Benz GLA 250 vehicles and other H247 vehicles are susceptible to foreign-material intrusion into the HVAC blower system and whether the existing intake grille/sealing design adequately prevents debris from reaching and damaging the blower motor. I further request that NHTSA determine whether Mercedes-Benz has received additional warranty claims, dealer repair records, blower-motor replacements, customer complaints, or other reports involving foreign material entering the blower assembly, abnormal blower noise, blower imbalance, or blower-motor failure.
