Example complaints

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

“I was driving on gallatin rd in tn , a busy 4 lane business district, when my Volvo C70 lost power and I was forced to coast into a church parking lot - I have a manual transmission. I didn't think anything of the incident until I saw a similar story reported on yahoo news. They replaced the computer under warranty and it is working fine now (2 yrs later), but had this been a busy highway, I would have caused a traffic problem.”

NHTSA complaint #10130991, filed 2005-08, 32,000 miles

“The car reduced the speed and now it stopped running because the etm is not working. I contacted Volvo and they said that the warranty is not covered because it has been over 10 years. I bought this car from a previous owner in october 2013 and therefore I was not aware of the problem. Now they want me to pay approximately $900 to fix it. They said the warranty started from the day the first car was bought which was august 25, 1999 but in my opinion it should be from the first time there was a problem encountered with the etm that caused Volvo to recall and buy the cars back. …”

NHTSA complaint #10610765, filed 2014-07, 15 miles

“Engine check light came on and we were told that nothing was wrong and it was reset. The second time the check engine light came on, the co2 sensor was replaced. The third time was the same day it was repaired for the 2nd time and the check engine light came on 20 miles later. The oxygen sensor was replaced again. In addition, the ignition & fuel injection fault tracing was found faulty. They also found that the mass air flow meter was faulty & had to be replaced, we've had problems with the air conditioner which has a constant ticking sound that they claim is normal for this model. …”
