While driving in town, making a legal u-turn at a safe speed, the power steering failed mid-turn and the car was very hard to control and the steering wheel jerked violently. It is unknown what caused the failure, however there is a recall on my vehicle concerning catastrophic steering failure. This steering failure was caused by faulty manufacturing/ equipment by gm.

Takata recall 15757. Drops of engine oil may be deposited on the exhaust manifold through hard braking. This condition could cause an engine compartment fire. So I took the car to doan buick gmc and the valve rocker arm cover and the gasket were replaced on 8/5/16. Then I was told that the rear valve cover and lower intake are leaking oil but may have other leaks. Which this was not part of the recall. So expects me to pay out-of-pocket for this. Also the transmission cooler lines are leaking some but not really bad. So he topped it off with 3 quarts of transmission fluid. When I would turn on the AC the car engine idled down and struggled to accelerate and will jerk. I had to turn the AC off so the car can pick up speed. Now its running fine for now.

My transmission/ transaxle has been rebuilt 3 times. What I have researched at this time is that the base model 4t65e transaxle doesn't really differ in the hard parts for the 4t65e-hd thats in my pontiac grand prix gxp. Bad jerking and slipping from take off or accelerating is my problem. Just this year my car couldn't accelerate over 40mph because of this problem. Anyone I talk to who has the same motor combination of the ls4 motor with the 4t65e-hd tranaxle has been dealing with the same similar issues. Wether it be the impala ss 2006-2009, monte carlo ss 2006-2007, buick lacrosse super 2008-2009, or the pontiac grand prix gxp 2005-2008. The front wheel drive combination with the power in the 303 hp motor is too much for the 4t65e-hp transmission. I've found a website that claims they have solved the flaws with this problem. The website explains in detail what parts they use and how it can support the power of the ls4 motor. Personally I feel like I should not pay for something that should've been a recall close to a decade ago.

When I would come to a stop and hit the gas to take off the car hesitate to go rpms going up but the car would act like it was not in gear. Then a jerk would occur and the car would take off making it scary to pull out into traffic. It took many times going to the dealer before they repaired it, it was linkage in the transmission, it was wore out. 5 years later it is doing the same thing.
