Why they failed: the share of failed tests with at least one fault in each area (a test can fail on several). Cars first registered in 2019, tested in Great Britain in 2023; first registration is usually, but not always, the model year. Source: DVSA anonymised MOT tests and results, Open Government Licence v3.0.
What do 2019 Mercedes-Benz C-Class owners report?
12 of the 79 complaints, the most recent for the most-reported components, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
The vehicle exhibits an intermittent, severe electronic-hydraulic transmission control defect where it completely rejects gear shifts from Park (P) to Drive (D), or forcefully defaults back into Park upon operation. The servicing dealership's diagnostic tear-down confirmed an internal failure of the mechatronic valve body and the integrated park solenoid at only 62,141 miles. A transmission that unexpectedly rejects directional electronic gear selection or commands unsafe safety-lock engagement while attempting to transition into active traffic flow poses an immediate structural traffic hazard…
The factory infotainment system (Mercedes NTG 5.5 head unit) displays Android Auto incorrectly. Instead of using the full width of the center display, Android Auto is cropped into a reduced window on the right side of the screen. The remaining roughly one-third of the screen shows a static logo with no function. Apple CarPlay on the same head unit and screen displays correctly at full width. This indicates a software or integration defect specific to Android Auto, not a hardware or display failure. Safety risk: Because navigation is pushed to the far right edge of the display and shrunk, the…

On the afternoon of February 6, 2024, as I was turning into my driveway to park in front of the garage, my car unexpectedly accelerated despite my foot being on the brake pedal. Despite my attempts to brake, the pedal didn't respond, causing the car to collide with the garage door and subsequently damage storage shelves and containers inside. My mother and two brothers were passengers, returning from my mother's doctor appointment, and she became trapped inside due to the garage door collapsing onto the car. Emergency services were called, and both the fire department and police assisted in…

Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports.
