MERCEDES-BENZ Complaints

Front crash with no airbag deployment and no emergency braking. Currently at The Metal Shop in Warm Springs Va. Told by insurance it is totaled. Sustained mild concussion from head trauma. Head hit steering wheel. I notice many Sprinters for sale for parts after similar front end collisions. No warning lights.

Rear subframe rotted / corroded. Rear brake lines rotted and rear springs broken from corrosion . Mercedes refuses to address the issues under warranty except the subframe issue . Almost crashed on i-84 with child in vehicle due to rear control arm being rotted from subframe .

I was driving home from work down the hwy, when the sun visor shade fell down and hit me in the head and covered my face, temporarily blinding me, like a blanket was pulled over my face. It's very difficult to see the road or other drivers when you are blinded at 70mph! Car only had 15,500 miles on it...

There is a recall associated with this model that causes catastrophic stoppage without any ability to drive. My vehicle VIN does not have a recall according to your site. Despite this, my vehicle catastrophically stopped multiple times. It was repaired at least three times and still stopped in the middle of the highway. My partner and I were stopped on I-85S with no ability to move, honk, put on hazards. Cars zoomed past at full speed. I called 911 as we braced for impact. We are lucky to be alive and now suffer from severe trauma. They eventually closed the entire highway and dragged the vehicle to the shoulder almost 30 min later. Mbusa was aware of this defect before rejecting my lemon law claim, but my vehicle was not included apparently. I feel more investigation is needed because it seems very likely my vehicle should be included in the recall. I appreciate your attention to this matter.

The sunroof panel being cracked on this car is a well known and documented issue. There have been several recalls for it just not on my specific model. Yet I’m just like them, stuck with a broken in half sunroof panel that let water seep in and ruin my sunroof twice now, and the only fix is to pay $4500. This is insanely high for the small panel I’m talking about.

The vehicle presented multiple warnings/errors before shutting down on the street in traffic on June 23, 2026. Warnings such as Collision Detected, Blind Spot Assist and Exit Warning Inoperative, PRE-SAFE Inoperative, System Failure Detected, Service Required Do Not Shift Gear, along with various lights on the dashboard which includes the Check Engine Light. The vehicle was towed to local Mercedes Benz dealership which reported the issue was with a drive train module that required a software update, the update was performed and vehicle was returned to me on June 25, 2026. On June 28, 2026 the warnings Blind Spot Assist and Exit Warning Inoperative, and PRE-SAFE Inoperative messages returned. Then on July 13, 2026 the vehicle shut down completely again in the same manner and error messages as initially reported. The vehicle was then towed to another dealership who reported seeing the same error messages, however they have not been able to replicate the issue after resetting the software.

The contact owns a 2022 Mercedes-Benz GLE350 4Matic. The contact stated that while driving approximately 35-40 MPH and depressing the brake pedal, several unknown warning lights illuminated, and the vehicle jerked and lost motive power. The contact pulled over to the side of the road until the vehicle stopped. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the dealer, where the accelerator pedal wiring harness and loosened pin segments were replaced; however, the failure recurred three days later. The vehicle was taken back to the dealer, where unknown repairs were performed; however, the failure persisted. The vehicle was taken back to the dealer, but was not yet diagnosed or repaired. The manufacturer was notified of the failure, a case was filed, and the manufacturer partially covered the second repair. The failure mileage was approximately 86,882.

Mercedes-Benz E350 Mild Hybrid was purchased new on XXX. Vehicle had approximately 291 miles and had been owned 25 days, when incident occurred on XXX at approximately 9:30am. Incident occurred during normal interstate driving (I-10 between [XXX] and [XXX]) at approximately the posted speed limit of 60mph. Weather was partly cloudy, not raining. A sudden loud explosive sound occurred, similar to a gunshot. There were no warning lamps, messages, or other symptoms prior to the explosive sound. Neither of 2 occupants in vehicle observed an object strike the vehicle. Sunroof was completely closed at time of incident. Passenger opened inside cover of sun roof and immediately observed shattered panoramic roof glass, with almost half of the sunroof gone. Remainder of sunroof was cracked into very small fragments. Glass appeared to largely disperse outward; interior sunshade prevented glass from entering the passenger compartment, although there were shards of glass lying within the sunshade. Vehicle was safely removed from traffic. No injuries occurred. But half of glass from sunroof was scattered toward other lanes of busy interstate traffic. Passenger safety could've been compromised had the glass torn the soft fabric sunshade. Passenger safety could've been compromised if driver had been distracted by the explosive sound. Glass could've been safety hazard for other vehicles behind mine. Mercedes-Benz denied warranty coverage and refused to provide owner a written engineering explanation of the cause of the accident. Mercedes-Benz field technical rep and dealer service department reviewed the car's damages. Vehicle has since been repaired at owner's expense. Owner has photos of damaged roof prior to repair. Owner plans to sell vehicle on or about XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear subframe is defective and subject to premature corrosion and failure of parts that connect to the rear suspension. Due to the fracturing of the joints connecting to the suspension, my car was at risk of going out of control when needing to brake at higher speeds. The way the suspension component broke also risked damage to the gas tank if the car was driven over a large bump or pot hole. The problem was diagnosed by an independent repair service. The corrosion is not visible to an owner. It does not impact any body panels - only structural parts visible when the vehicle is on a lift. Mercedes Benz has provided an extended warranty for unlimited miles and 20 years to any owner of this model for a range of years and models. This was communicated to Mercedes Benz dealerships on March 10, 2023. However, since the vehicle is not subject to recall, I do not know how this was communicated to an owner. I did not receive anything alerting me to the problem. Mercedes Benz has my phone number on file.
