Tl* the contact owns a 2009 buick enclave. While driving 50 MPH, the vehicle started to jerk, the gears slipped, the rpms increased, the vehicle failed to accelerate, and the check engine warning indicator illuminated. The contact coasted the vehicle to the side of the road and powered off the engine. The vehicle was restarted, but the failure recurred. The vehicle was taken to an independent mechanic who diagnosed that the transmission failed after having the vehicle for 9 months and needed to be replaced. The vehicle was not taken to a dealer and was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.*dt

Tl* the contact owns a 2009 buick enclave. While driving 45 MPH, the vehicle hesitated, jerked, and failed to accelerate. The vehicle was taken to an independent mechanic who diagnosed that the #1 cylinder misfired and the plugs and pcv valves were replaced. The mechanic then took the vehicle for a test drive and diagnosed that the transmission failed and the vehicle could no longer be shifted into reserve, third gear, or sixth gear. It was diagnosed that the transmission wave plate failed and needed to be repaired or replaced. The vehicle was not repaired. The manufacturer stated that there were no open recalls. The approximate failure mileage was 130,000.

When driving at very low speeds the steering binds and/or locks up causing the vehicle to stop turning. With extra applied strength the steering suddenly turns causing a severe jerk in the car's turning motion. There have been several near misses, telephone pole on 03/07/16, it happens very unexpectedly. Over the past weeks the problem has increased to happening at most every parking lot, slow turn in or red light/stop sign turn. Initially it was only happening when turning as the car was backing up but now it's a constant issue.

In the past I had jerking or slipping of transmission at approximately 40 miles an hour, or the engine was having a coil miss fire. I had 3 new coils installed by dealer under warranty with similar problems before. Took to dealer and they could not determine if transmission was slipping or engine miss firing, but no code on miss firing engine. Slipping or hesitating of transmission is more likely but can not determine since does not act the same consistently. Steering noise started in the winter approximately november 2013, but off and on since; steering seems a little stiff but not failing yet like so many other complaints I have read about here. I was charged $342.81 for dirty throttle body and oil in the air dust tube which might cause misfire, they cleaned and replaced bank 2 value cover and cleared codes, performed idle lean reset. This did not fix problem on 05/19/2014. I returned on 06/10/14 and left car till 06/11/14 the dealer let me use a loaner over night. The dealer said stumble/misfire at times was not acting up enough to diagnose. I had the cars automatic transmission flush service on 02/26/14 and there was no problem at that time. In the course of owning this vehicle I had 3 coils replaced with problems starting 01/05/10 one coil, second coil on 08/11/10. Third coil shortly thereafter, this is after complaining since 12/02/2009 about engine shudder. The misfire/stumble is still happening about 40 MPH and sometimes around 20mph if you are slow going but not on a pull or accelerating. We love the car, but the problems are getting expensive and the worry of what else can go wrong is stressful. I did not mention the warranty repairs of water pump going out front motor mount failure, shift lever, airbags, seat belts, left out remote mirror failure, engine and transmission code updates. Dealer seem ok, so gm can not fix or will not due to cost.

Power steering fails intermittently in parking lots and at slow speeds. Am almost unable to turn the steering wheel at all, then it "gives" causing the car to jerk.
