Example complaints

“The check engine light came on, on my 2001 suburban at 29,000 miles. This was my dads vehicle and was garage kept and driven on trips or to church in rural texas, which is why after 8 years it only had 29,000 miles. I had it scanned at auto zone. A #1 cylinder misfire was detected. I moved the coil, spark plug, and wire to other cylinders to isolate the problem. The scan still detected #1 cylinder misfire even after driving over 50 miles. The misfire was not detectable by the way the truck was running. I went ahead and replaced the injector on that cylinder just to rule it out. …”
NHTSA complaint #10282635, filed 2009-09, 29,000 miles“Noticed no bolt head on drivers side rear exhaust manifold, was not sure if it was supposed to be there. Then found another bolt head in skid guard during oil change, this was from the front bolt of same exhaust manifold! The heads broke off cleanly for no visible reason. Fixed front bolt but rear one requires exhaust manifold removal at cost of $400.00. This could be very dangerous if more break!”
