Example complaints

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

“While trying to merge into highway traffic (i94 in michigan) I pressed the accelerator to gain speed to merge only to find that the engine lacked any power, the rpms rose slowly but there was little to no acceleration. I was told (by mercedes dealer) that this is a known issue and in this case it almost caused my death. If this is a know issue why are our lives being put at risk because of a poorly designed part?”

NHTSA complaint #10870938, filed 2016-05, 213,000 miles

“While driving, normal acceleration lagged more than usual. When I submitted car for service, I was told foam around injectors has melted into the injectors. This damaged three injectors on one side to the point of complete replacement (approximately $800 each). I was told I caught this situation early.”
