Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I bought this car brand new. Since its 80,000 miles mark the dealership has been having trouble fixing the camshaft position sensor. This defect causes my car to stall in ongoing traffic and caused it to come to a roll and stop. My car has been in the dealership for 2 whole months where it has been test driven and now has 100,000 miles on it. The air bag light stays on even after it has been turned off.”
NHTSA complaint #10162013, filed 2006-07, 80,000 miles“I came to a complete stop after driving only 10mph, my engine cradle dropped down there for smashing through my front axel, and turning in both of my front wheels. Not realizing what happened I continued to drive to a repair shop. Both tires popped. I called a tow truck and paid an outrageous amount to get a tow to a repair shop. I was without a car for 2 weeks while they replied my vehicle which cost me almost $1,300. My insure company would not total out my vehicle because they said it was due to salt corrosion and rust (ware and tear). Did I mention I was on vacation when this happened? …”
NHTSA complaint #10505488, filed 2013-04, 130,000 miles“Engine misses and backfires through the intake. The major problem is when the engine is running and it doesn't matter if it is in park, or if you are driving it. I was on my way to work when it malfunctioned. I was sitting at a signal light when the engine accelerator went up to 4200 RPM by itself with no foot on the pedal. I almost got into an accident, I pressed harder on the brake pedal and had to take it out of drive to avoid hitting the car in front of me. …”
NHTSA complaint #10064050, filed 2004-03, 44,001 miles“I bought this car new. Less than 4000 miles ago, I was at the dealership to correct a check engine light condition, which was fixed under warranty. I was told that at the mileage the car was at I needed routine service on the transmission under terms of the warranty. This was done. I was also told that my serpentine belt and spark plugs were due to be replaced. I was not reminded that my timing belt had to be inspected before 60000 miles. While driving at 65 MPH, the engine stopped running. It was towed to the dealership. …”
NHTSA complaint #10106327, filed 2005-01, 60,255 miles“I bought my 2001 Hyundai Sonata less than 2 years ago. Since that time I have had to replace both window motors, front and rear brakes, timing belt and all tires. I would have thought that a brand new car would be trouble-free (that's why I chose Hyundai, because of the great warranty) however, it appears that is not the case. My car recently broke down on my way home from work, had to be towed and was in for repair for a week (timing belt), which was a huge inconvenience and expense for me. …”
