Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My car has only 28,392 miles on it, but the yellow check engine light recently came on due to a faulty oil pump solenoid. I took it back to the dealership, and the repair cost was a staggering $7,000; they told me this is a common issue with this Mercedes engine. If this fails to function, engine noise will increase while driving and fuel consumption will rise; there may also be other unknown risks. …”

NHTSA complaint #11745528, filed 2026-06

“The engine/check-engine and cold-start noise problems have recurred despite multiple dealer repairs. In July-August 2025 the dealer documented misfire codes and a loud screech after cold starts. Its Aug-Sept repair order recorded the check-engine light returning one day after coil work, coolant entering a cylinder, and head-gasket/injector work. The dealer reported a completed test drive Sept. 17, 2025; the owner reported the vehicle broke down again Sept. 24 after only a short period of use. …”

NHTSA complaint #11769461, filed 2026-10

“The vehicle repeatedly had a check-engine light and the same engine-related complaint during multiple repair visits. The dealer attempted repairs several times, including an engine rebuild and later cylinder-head work. Despite those repairs, the engine later failed. The same loud screeching noise has now returned on cold start and lasts about 7-10 seconds. This is the same recurring problem that brought the vehicle in for repair. I believe the repeated failure to correct the condition led to the engine failure; the cause of the current screech has not yet been independently diagnosed. …”
