Verbatim excerpts from NHTSA complaints, by component

Fuel/propulsion system

5 reports
“A couple of months ago, my car started running a little rough as it would sit in idle mode. When suddenly my check engine light came on. I checked the codes and they seemed to be P0445 Evaporitive emission system leak detected (large leak). And P0441 Evaporative emission system. Incorrect Purge Flow. P0505 Idle control system. And P0171 System to Lean Bank 1 and P0174 System to Lean. Bank 2 and P0172 System Too Rich and P1170 and P117B Manufacture Control. But other then just running a little rough at idle that was about all that I had noticed until I went to go fuel up back in October. My fuel was low so I went to fuel up and after wards, my car struggled really hard to start. And every time since that days it’s progressively gotten worse. Last week I kept my car running while I fueled up and as I drove away from the gas station, my car just stalled out completely. It took me about an hour and a half before my car would start again. I was waiting for the tow truck to come get me and thank God inc checked it one more time and it started. Now just recently, when I put my car in park the engine immediately Reva up super high. It started to wine really loud and…”

Forward collision avoidance

2 reports1 crash
“on 3 lane expressway (US422)about 1/4 mile from where the lanes split( see attached). No cars in front of me but cars in the lane to my left slowed. My car suddenly braked causing the car behind me to swerve to my right to avoid a collision. The adaptive breaking (incorrectly) determined that there was a collision hazard, thus creating an actual collision hazard”

Wheels

1 report
“I brought my vehicle for a suspension realignment service. They performed the realignment service, but informed me that the side wall of the front right wheel was cracked. I took a look crack and it seemed like an attempted man made cut to up sell a replacement. The tire is only 2 years old according to the DOT code, so the environment is unlikely to be the cause. The tire was also brought it to another tire shop for re-balance around 2000 miles ago and they did not try to sell me a replacement tire. The cut looks like something that a blade could replicate, not a curb. I suspect that this tire shop has some kind of quota pressure on their technician to detect faults on the tire to increase tire volume sales. It is likely they could of made a puncture with the expectation that the buyer would replace it on the spot. I brought up the issue w/ the owner and they were denying it initially but did make a comment on the video footage. I did not go with that option, since I was in a hurry to go to work on that day and a bit skeptical if they would selectively release the video footage. I didn't want to call the police/law-enforcement directly to obtain the full…”
