 My tahoe will jerk backwards really hard. then i get error messages stating the stabilitak has malfunctioned traction control off service engine and last but certainly not least reducing engine power. i cannot go over 15 when this happens, which makes it really hard to get off the road when this is all happening. the whole vehicle bucks back and forth wildly as the cyclinders are shutting down. this is a terrifying experience since i have 2 small children in the car with me. now my car is not safe to drive. if i do try to drive it it grinds and makes horrible noises and the service engine light is now permently illuminated on my gauges. i cannot turn the vehicle with out it completely stopping...on its own...my foot will still be on the gas. also it accelerates on its own...we live in nd and get tons of snow and ice. this thing is a death trap. i have purchased a vehicle that i cannot drive...but still must make payments on. it is a total lemon!

 I have a gm product. a 2009 chevy tahoe with only 7,000 miles on it. it turn off itself witout any warning i am approaching the stop sign or traffic light and when start to turn i noticed the vehicle have turn off itself. since i can not steer well since the vehicle is off is then when i can hit a car or cause a rear end crash because i am abruptely stoping. i had to put the vehicle in parking and the vehicle start right away with hot air coming from the vents of the air conditioning. the vehicle came with a 3 year 0r 36,000 miles warranty. i took the vehicle to the dealership and no codes are coming. this always occur randomly and when approaching intersections and in two ocasions i almost have an accident. i have talked to the dealership here in lake city and they told me that the vehicle is not on the recall but is showing exactly the problem described in the recall. i also wrote a letter to gm along with the recall and no action is taken by gm. as myself i hope we don't have other customer accross the nation dealing with this problem and gm not acting and dealership not acting i learn my lesson with gm. *tr
