Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“An incident with the vehicle occurred sometime around christmas 2011. The motor surged while I was fully stopped at a street light. The motor was running, the car was in drive gear, and my foot was on the brake. I was able to quickly bring the car under control. A second event occurred in 2012, may 15th, at 11:00 p.m. While I was fully stopped at a drive through window. Again the motor surged, this time with a loud screeching sound. I applied maximum brake pressure but the car continued to surge forward, approximately six feet. …”
NHTSA complaint #10504702, filed 2013-03, 97,500 miles“Jaguar 2004 failure of accelerator sensor while driving on I-40/i75 in knoxville, tn resulting in a instant shutdown of engine that could have resulted in a fatal or near fatal accident by being run over by traffic from the rear. Resulted in a 900 dollar repair as sensor was a part of throttle body that according to dealer had to be replaced. I am questioning that Jaguar can have a car on the road that does not have a backup for this type of failure.”
NHTSA complaint #10242341, filed 2008-09, 27,617 miles“I was braking into a parking spot at the bank when without notice my vehicle accelerated wildly. I pressed on the brake with all of my weight to stop from literally ramming my vehicle into the side of the bank. The roar of the transmission was like someone was stepping full force on the gas pedal, but my foot was solidly on the brake and not even touching the gas pedal. It was terrifying. If there happened to be someone walking on the sidewalk in front of me, I would have hit them. I wouldn't have been able to avoid it. …”
NHTSA complaint #10215695, filed 2008-01, 29,450 miles“I was braking into a parking spot at the local bank when without notice my vehicle accelerated wildly. I pressed on the brake with all of my weight as if my life depended on it. The roar of the transmission was like someone was stepping full force on the gas pedal, but my foot was solidly on the brake and not even touching the gas pedal. It was terrifying. I could hardly keep from driving into the side of the bank. If there happened to be someone walking on the sidewalk in front of me, I would have hit them. I wouldn't have been able to avoid it. …”
NHTSA complaint #10215686, filed 2008-01, 29,000 miles“While proceeding to park in the driveway, the vehicle experienced a sudden acceleration and forcibly struck another vehicle that was parked in the garage. During this incident the driver had no control of braking or steering. The impact was severe enough to cause the airbag to deploy and sustain major damage to both vehicles.”
