Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Car surges randomly at lower speeds. Car also loses power on freeway and acceleration fluctuates uncontrollably at times. All symptoms happening while car is in motion, mostly at speeds over 50mph. I brought the car to my local dealership where there were open recalls on the model I own. After recall was performed, the symptoms have increased and worsened. Dealership is refusing to take any responsibility.”
NHTSA complaint #11018946, filed 2017-08, 158,000 miles“I was driving my 1999 Volvo V70 on the highway, and it constantly accelerates and decelerates on its own with no action done by me. In one case it accelerated to the point in which I lost control and caused an accident. Vehicle is in the process of having the etm replaced at the dealership at a cost of 1000.00 to me because it is outside of warranty coverage.”
NHTSA complaint #10153475, filed 2006-03, 220,000 miles“I have a 99 Volvo V70 t5, on july 3rd of 2006 we had the vehicle in as the etm light was on, the dealer upgraded the software of the etm at no cost, now a year later the vehicle is undrivable. It surges at low idle causing the vehicle to jump forward, it consistently stalls out and now is beginning to surge while driving down the road at any RPM. I feel that this is a extreme hazard and I am no longer able to drive the vehicle.”
NHTSA complaint #10196673, filed 2007-07, 74,890 miles“Failure of electronic throttle system occurred. No injuries due to immediate discontinued use after warning light illuminated. After light illuminated, I drove the car straight home from work, parked it and am currently researching where I will take it to get repaired. I have recently read numerous articles on this problem that others are having as well, and wanted to note this incident as well.”
NHTSA complaint #10137250, filed 2005-09, 98,020 miles“The ets (relating to throttle control module) keeps coming on during acceleration followed by very sluggish performance of vehicle. Previous times upon light up, I've taken this to the dealer and both times they state nothing was wrong and reset the system. This should have been replaced during the warranty period. I'm afraid that there could be a major accident soon due to this problem.”
