Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was recently involved in an accident where I passed out while operating my vehicle. I believe that carbon monoxide poisoning was the contributing factor that caused this accident. Faulty exhaust manifold fasteners seems to be an issue that could have caused this accident. I was shocked to see that there is no recall for this problem. I have incurred numerous personal expenses due to the accident, but feel lucky that there were no serious injuries or fatalities. …”
