2023 Mercedes-benz GLA-Class Complaints

I am reporting a severe drivability and engine failure issue with my vehicle. The vehicle has been exclusively maintained by authorized Mercedes-Benz service centers. Immediately following a scheduled 60,000-mile (Schedule B/C) maintenance, the Check Engine Light began cycling on and off. The vehicle simultaneously developed severe drivability symptoms: the engine ran extremely rough, and acceleration became erratic and "jumpy." This unpredictable power delivery and hesitation poses a significant safety hazard when accelerating or merging in traffic. I immediately returned the vehicle to the service center to report the issue. The dealership has now retained my vehicle for over 20 days and diagnosed that the cylinder head requires complete replacement. Despite this catastrophic failure occurring immediately after their maintenance procedures, the dealership is holding me financially responsible for the repair costs because the vehicle is past the 4-year/50,000-mile warranty. My vehicl...

On 2 separate occasions (August 2025 & February 2026), the car has had a "transmission malfunction" light come on while driving on the highway around 65-70 mph. The light comes on and immediately loses ability to accelerate. Both times the car was towed to Greensboro Mercedes. The first time they did not do anything because they didn't know what to do and it had "reset" itself. The second time they discovered that it needed a software update. Mercedes does NOT have the update that is needed. We tried going through the lemon law process but Mercedes Corporate came back with an answer of it hasn't happened enough times and a remedy has not been attempted enough times. They have NOT attempted to fix it because they DO NOT have a fix. This IS NOT SAFE for my daughter to drive. This is her car and it has been in the shop since February 2026. We purchased the car from Bob King Mercedes in Wilmington, NC as a certified pre-owned in 2024. Both dealerships have been great to work with and stand...

[XXX] we were driving to San Francisco. Traffic was very light because of the upcoming Thanksgiving Holiday. We were about 1000 feet from the toll plaza, driving at 50-55 MPH. There was a car behind us about six car lengths back. There were no cars in front of us between us and the Toll Plaza. Nothing at all. There were no cars in lanes to our left nor right in our vicinity. Suddenly our car made a loud GROWLING noise and the car jammed on the brakes! My wife screamed but we did not come to a complete stop. A bright Red Triangle appeared in the center of the instrument panel. Then it stopped and we drove on because there was the car behind us approaching quickly. I believe he swerved and went around us but I cannot be sure what he did. I just know he did not hit us, thank God! Prior to going to the Dealer, I notified the Dealer and MBUSA Customer Service on a 12 minute call of the problem. MBUSA said they would notify the Dealer and get back to me to investigate. When I arrived...
