This Problem Across All Years
My vehicle has been taken to the Mercedes dealership multiple times from 2/24/25 -12/14/25 (10 Mths) for the following issues and still no resolution to the problem. Each time they say they've fixed the issues we get the car home and end up bringing it back a couple days later for the exact same issue. The issues being the Instrument Cluster/Panel failure (check engine light, multiple warning lights on display while driving, dash display is blacking out and unresponsive). The speedometer, fuel amount and mileage is also blacked out and unresponsive. The headlights, and tail lights also go off and are unresponsive while driving. We've also experienced the vehicle not going in reverse or drive and had to return it multiple times for this as well. These incidents are very serious safety hazards to the driver of the vehicle, other drivers and pedestrians. On several occasions we've addressed these problems with the dealership and still no resolve. However, we are paying very expensive labor fees only to return it with the same problems repeatedly and no explanation as to why the problem keeps recurring. We have receipts, photos and videos of this problem because the dealership kept stating they weren't seeing the issues we were seeing. However, after we presented the evidence and confirmation we have, they stated that they would conduct a diagnostic test and take a look, but the issues still have not been resolved after several times picking it up after they stated that they had changed the instrumental cluster. The last time after we returned it they discovered they had put the wrong part in the vehicle, however the same issues occurred with that part as well which is the reason we returned it to be looked at again. They changed it and still the same issue has repeated again. This is concerning and alarming that we were trusting them to work on the vehicle and driving the vehicle home thinking it is fixed and then discovering that they had put a wrong part in the car.

Dear NHTSA Office of Defects Investigation, I am submitting a safety complaint regarding my 2018 Mercedes-Benz GLA 250 (VIN: [XXX] ). On October 28, 2025, while driving southbound on Interstate 5 near the Zamora Exit in California at approximately 8:15 a.m., the fully closed moonroof of my vehicle spontaneously shattered. There was no impact, debris, or external cause, and the vehicle was operated under normal conditions. The incident was extremely frightening and created a serious safety hazard while driving at freeway speed. I began shaking uncontrollably and immediately called my manager to report that I could not come into work due to shock. I also contacted my mother to help calm me down. Vehicle Details: VIN: [XXX] Mileage: 90,XXX miles Purchase: Approximately 5 years ago at Fairfield Mercedes-Benz dealership Condition: No prior repairs to the moonroof, no aftermarket modifications I have documented the incident with photos and video. I have reported this to Mercedes-Benz Customer Care and my insurance provider (USAA). Additionally, I have reached out to Washington Law Offices, who are currently handling a class action lawsuit regarding this issue. I am submitting this complaint to formally notify NHTSA of the dangerous defect and to request that the agency investigate this potential safety issue affecting Mercedes-Benz vehicles with panoramic or sunroof systems. Thank you for your attention to this matter. Please confirm receipt of this complaint and advise on any additional steps I should take. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle has a transmission control module defect. While driving, the car cuts off unexpectedly and prevents shifting gears, creating a serious safety risk that could easily cause an accident. A certified Mercedes-Benz dealer diagnosed the problem and confirmed it is an internal defect—one that cannot be prevented by regular maintenance or proper care of the vehicle. Because this is an internal issue, Mercedes-Benz should take immediate responsibility to repair it, rather than delaying or shifting accountability.

Crankcase Vent Valve needs replaced. Causes jumps in acceleration and pressure build up. Was a recall in other models. Took to a dealer today to confirm the check engine light and this was the cause.

The car makes a clunking sound when driving at a low speed or backing up. The clunking noise occurred after I bought it. The clunking noise began around 65k miles. The wheels make a rubbing noise also. I took car to my mechanic, he could not find anything.

I was getting a warning sign on my screen in car. Is said safety problem. I tried to tell Mercedes’ but they did not want to see the car . They told me to go to the mechanic who did a small job fixing the car due from a small collision. I did take it back and mechanic said he didn’t touch that. When I was going through all of this I told Mercedes’ financial to hold on my account . I did not want to pay for an unsafe car. The financial dept. agreed and I asked them to note it that I called about this issue. Because of not paying they repossessed the car and I could t do anything about this but pay. The car was leased and I did not want to pay for a car that was unsafe. Now I have a credit to pay off 13000 and I don’t want this . I tried to contact the company and got redirected to places that didn’t rely of do anything . I wanted a replacement . If I have to pay I wanted them to give me a car because I don’t have one since. The account disappeared and there was no notes on what happened all I have was the pictures of car and the write up from the mechanics inspection . He saw There was something wrong . I sent in letters and the punctures but got nothing back. I emailed the sakes guy to tell him, this was revolt and no reply . I was right and the car got recalled shortly after this . It’s not fault of my own it is the car company to support their customers . As a consumer my rights were ignored and I am demanding some kind of compensation for this. I asked for a replacement and no reply the vin number is [XXX] glc gla?? 300 black I lost the car in 2019 and have not had a car since .a repossession in my credit report does not help me My address info [XXX] I could not even get a copy of my contract due to a wipe out of my account .

I GOT HOME AND WHILE WAITING FOR MY GARAGE TO OPEN THE PANORAMIC SUNROOF EXPLODE AND SHATTER WITH NO REASON, LUCKILY IT DID NOT HAPPENED IN THE FREEWAY, I READ THAT HAPPENS BEFORE TO A PILOT. THE DEALER WANTS TO CHARGE $250.00 JUST TO CHECK A BROKEN SUNROOF AND WONT ACCEPT THE DEFECT.

THE PROBLEM IS WHEN TRAVELLING AT LOW SPEEDS OR STOP THE CAR TO HALT ABLE TO HEAR A NOISE FROM THE REAR END. LIKE A METAL HITTING ANOTHER METAL. IT HAS BEEN ONLY 1 MONTH I BOUGHT THE CAR AND 1300MILES ON IT. THE CAR IS MAKING REALLY LOUD NOISE WHEN STOPPED AND HEAR IT PROPERLY. IT IS MAKING CLING CLING NOISE. I REALLY WORRIED ABOUT THIS ISSUE. I ALMOST OBSERVE EVERYDAY.
