Example complaints

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

“Lost clutch to the floor while driving nearly having an accident. Took off clutch master cylinder as symptoms would suggest the repair would be. Found out that the pedal assembly is broke and that the firewall is cracked I can see lots of posts online where this seems to be very common and very dangerous”

NHTSA complaint #10780823, filed 2015-10, 110,000 miles

“5 months ago, took car to Mazda dealer for timing chain, vvt noise and was replaced under extended warranty. Last month started to feel intermittent loss of power during quick acceleration followed by plume of smoke at the tail pipe. Took to local mechanic shop and was told there was heavy carbon buildup at the valves as well as mass air flow sensor, o2 sensor, and other engine components. The bill was for about 1800 worth of parts and labor for deep cleaning the valves (intake manifold removed). …”
