9/9/24 after 5pm I'm driving my car and the check engine light came one. I have a small autel handy scanner always in my car. I checked it right away and gives me the code P06DA (OIL PUM SOLENOID OPEN CIRCUIT - ELECTRICAL ISSUE). I stop on the side for a quick check, no knocking noise from the engine and runs good. I checked on the website (Mercedes forums) and a lot of people had the same problem (lemon???). Most of them talking that thanks God the solenoid stuck on full open (higher pressure oil) so there's no damage to the engine. Repair cost around $5000!!!!! That problem must be taken seriously from Mercedes! Thank you

I am reporting a serious safety defect in my 2019 Mercedes-Benz GLS450. My vehicle experienced low oil pressure warnings and engine warning lights, which were diagnosed as a faulty oil pump solenoid valve. The repair required removing major engine components, resulting in a cost of $5,000 that I paid personally. It is important to note that Mercedes-Benz updated the valve design in the following model year, indicating that the company was aware of a defect in the original design. This demonstrates that the failure is recurring and not isolated, creating a serious safety risk—low oil pressure can lead to catastrophic engine failure while driving, endangering the driver and passengers. I request that NHTSA: Document this as a potential safety defect. Investigate the prevalence of this iss

Update Communication Module SIM Card Software - MBUSA ID: [XXX], NHTSA Recall ID: 22V365. I received the recall letter from MBUSA in July 2022. I took my car to a local dealership on 8 Aug 22 and they told me after approximately two hours they couldn't update/do OTA. They told me I would need to park my car outside to receive the update. Once I got home I checked the MBUSA & NHTSA recall sites and noticed this recall for my vehicle shows it as updated, but I knew the dealer hadn't accomplished it, because they said they didn't. I'm not sure who submitted it as updated on both websites. We have the MercedesMe Connect applications on our iPhones and it shows the status of our vehicle, allows remote starting, has anti-theft tracking as well as valet tracking and remote disabling capabil

The panoramic sunroof spontaneously shattered while driving down the road. The glass blew out from the inside out. There didn't appear to be any issues with the sunroof before this. As far as safety, just the noise of the explosion was enough to surprise the driver causing a jerking of the steering wheel into the opposite lane of traffic which could have caused a head on collision. If the sunroof shade would have been open, the glass would have came down the drivers and passengers as they were going down the road. Saying this was distracting is an understatement. I called the local Mercedes dealership and was completely dismissed by them. They said it would have to be repaired by a glass company which is incorrect. The glass was replaced by the local collision center.

factory equiped jack lift failed, bearing and ring ejected and vehicle fall on the ground, contacted manufactory, and Mercedes indicated they probably can replace a new jack but no more action they will take, the vehicle has a gross weight about 6400lbs, and with air suspension, the vehicle will need to be lift higher than normal in order to replace tire, the jack lift is obviously not hold the pressue that make it a serious safety concern, Mercedes should look into it not just drop the ball.

I was driving on the freeway and my windshield exploded.

Failure of driver side front axle CV assembly. Part #166-330-33-00 with 36,000 miles on the vehicle Noise was heard when driving, pulled over heard noise as moved car forward and made left turn. Car was towed to Highway Tire and Auto near our house on a Saturday morning. Car test driven on their lot and immediately identified as CV axle. Part was only available from Mercedes dealership, yet all the other axles ( non driver side) were available from several parts distributors. Seemed odd maybe indicating a lot of these were being replaced?? This axle failure while driving at highway speeds could have resulted in wheel lock up causing serious accident and injury. When contacting Mercedes they seemed more interested in telling me it wasn’t covered under warranty, and there was n

Just financed vehicle from M Auto group nj they sent my vehicle to Mercedes dealer prior to me taking ownership and the dealership advised them of issues with truck they only fixed the water pump . The problem is that same day I drove home ACTIVE CURVE MALFUNCTION and hydraulic fluid is constantly leaking under my hood and on hot turbo on passenger side which is a safety hazard I advised and drove truck back to dealer and they won't talk about fixing issue and I'm financing this truck which is a less than 30 day issue.

At first, the parking brake assist would appear when vehicle was put into park or when starting. We would have to release the parking brake each time. Then, the parking brake assist light would not go on, but the parking brake assist would engage and or be sticking while driving causing a burning smell and damage to the rear braking system including brake pads and calipers. The independent repair professional described this as being a very premature issue for this vehicle considering the age and mileage. The electronic parking brake actuators electric motors malfunctioned and failed causing resistance on the calipers. The car was undrivable and required us to obtain a rental car for several days.

Vehicle was damaged by a school bus hitting the rear passenger corner. It damaged the rear tail light, brake light, turn signal and backup warning sensors. Parts to repair the vehicle are not available for the past 4 months. I called multiple times and the dealer cannot provide a date when the parts will be available. The total cost of repairs is $3200.00. To avoid paying rental car fees that the school would have to pay, I’m driving a unrepaired car. The cost to rent a car would exceed the cost to repair the vehicle by 3-4 times the total repair cost. It is a law that car manufacturers have parts available to repair vehicles damaged by accidents. I would like NHTSA enforce the law.
