Example complaints

“When coming to a stop going about 5 MPH towards a stop sign, my van accelerated into traffic. Because the van jolted me into oncoming traffic, it almost caused an accident. It doesn't seem to matter whether I am braking or coasting, the van will accelerate uncontrollably.I have two children and not only am I putting their lives at risk, but mine also. I am not able to drive this vehicle due to how dangerous it is.”
NHTSA complaint #11175789, filed 2019-02, 99,000 miles“While driving on an expressway with steep grades, with the cruise control set, the speed on steep downgrades would increase by up to 5 MPH above the speed set on the cruise control. In other vehicles I have driven in recent years, I do not recall the speed variation exceeding 3 MPH from the cruise control setting.”
NHTSA complaint #10482457, filed 2012-10, 8,900 miles“Toyota Sienna mini van spontaneous acceleration our minivan spontaneously accelerated. I don't know if you know Toyota has been having this issue with older models, but ours is a 2012 Toyota Sienna xle limited all wheel drive mini van. I put on the brake to let my wife out when the van took off as if I had the gas pedal to the floor, yet my foot was on the brake. We kept moving, so I pushed the stop/ignition button and the van would not stop. I then put on the emergency brake and the van was still moving, I watched the RPM's keep going up on the tachometer. …”
NHTSA complaint #10499492, filed 2013-02, 24,000 miles“When pressing the brake the engine revs suddenly and to very high rpms and you have to press down on the brake and/or throw car into neutral/drive and then eventually the issue resolves. Happened yesterday when reversing very slowly out of driveway--was pressing brake (not accelerator) and suddenly the engine got very loud and was revving up. Pressed brake hard and thru the car into park and pressed the accelerator and the engine went back to normal. Very scary. Has happened several times before and fortunately we have not run into anything and the car has not taken off at high speed.”
