Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Twice, within 50 metres of the same spot each time, my car has suffered extreme acceleration whilst I was braking as hard as I could. First time, my mechanic checked all computer diagnostics using two different computer testing devices but there were no fault codes. Now, as well as happening twice within 50 metres of the same spot, I was at the same set of traffic lights, which I do not suspect as being the problem, but also next to a major hospital with an adjacent helipad. …”
NHTSA complaint #10471485, filed 2012-08, 78,000 miles“In the last month our 1999 S70 Volvo has stalled - once when traveling at slow speed and the other accelerating from a stop light. In both instances the car could be restarted. Also, the check engine indicator illuminates frequently - as it is now - and when taken to the dealer we are advised they can not find anything wrong.”
NHTSA complaint #10130849, filed 2005-08, 106,056 miles“Beginning in april of 2005, the engine on my 1999 Volvo S70 had stalled several times. In each instance, it has restarted and operated, however, the stalls are becoming more frequent. I have read or the NHTSA's investigation into this problem, and am concerned about my vehicle's operation and repair costs.”
NHTSA complaint #10131793, filed 2005-08, 90,000 miles“At approximately 206,000 miles my car wouldn't drive over 40 MPH, the engine would rev up on its own and sputtered throughout the reduced RPM range. Rpms would not go over about 3500. Check engine light came on. Drove it to Volvo dealer and they replaced the throttle body at an out of pocket cost to me of approximately $1,000. They stated that it would have been covered up to 200,000 miles as this part had a recall. I do not feel that I was adequately notified of the recall. …”
NHTSA complaint #10231286, filed 2008-06, 206,000 miles“My 1999 Volvo S70 has been stalling on a daily basis for some time now. I stall on my way to work; a seven mile drive. I have tried to get it in for service at a local Volvo dealership, but they are booked up . I have no other means of transportation beside this death trap. I pray all the way to work. Today it refused to idle up to a normal speed (35) and stuck somewhere at 15, so I coasted in until it finally stalled in the parking lot. This is a daily occurrence.”
