“Vehicle was in low range going in reverse with a trailer very slow when out of nowhere it engaged faster and wouldn't stop accelerating for 15 feet of this and it stopped my foot was not on the gas so there was no reason why it should have engaged in the manner that it did in fact I had both feet on the brake trying to stop it it felt like I hit something when it stopped but I didn't hit anything. This all occurred while I was backing a boat into my driveway which is level ground”

“I own a 2003 Lexus GX470. On friday january 8th as I waited for traffic to clear before turning right to enter a blvd, the engine suddenly began to race while my right foot forced down the brake pedal to prevent the car from launching into the cross traffic. The vehicle began to shudder and shake and my dad yelled you're spinning your tires! I yelled my foot is on the brake, what should I do? We turned off the ignition and the engine stopped running. …”

“My SUV when ever going up or down a hill at any speed lets out a horrible smell. I took it to the dealer and they claimed it was bad gas, I let the tank run to empty and switched gas dealers...the problem got worse. My son cannot ride in the back seat because he feels like throwing up even during short rides.”
