2008 Buick Lacrosse Vehicle speed control Problems

“The vehicle start making a funny noise and it kept getting louder and louder, then all of a sudden it cuts off. I was able to restart the vehicle after I sat for a while but it is still making a funny noise. I have been told by a mechanic today that it is the power steering. That will have to be fixed. I am sure that it will cost a lot of money.”

“Once in a while it acts up where it states that it's got low oil pressure even tho it's got plenty of oil,also it has misfired during when this happens. It's like this: I'm driving. Everything is fine until all of the sudden I notice engine light is on also the t/c light comes on and it also states the low oil pressure and the acceleration pedal it acts up. For example, I'm giving gas and it isn't accelerating as much as it should be and it totally fluctuates. I've also had the car misfire and shut off during one of these episodes as well. …”

“While driving at 35 MPH or 50 MPH car slow down to 10 mphstops and won't accelerate(gas pedal is hard won't give gas) . Engine light comes on and chimes saying reduce engine power and traction is off (service traction). When try to steer of the road steering wheel is hard to turn. I have had the throttle body clean and it's still doing the same thing. Very dangerous when driving at night. Gm needs to fix all problem won't drive to dangerous. Can you please help me purchase car march 2012.”

A notice appeared on the dash control: engine power reduced and service traction control . If I held the accelerator pedal down all the way to the floor, after about 5 seconds the car began to accelerate quickly. I could then maintain speed by alternately stepping on and releasing the accelerator pedal quickly. Accelerating from a stoplight is a very slow and disruptive (to traffic) process. …”

“I turned right onto a very steeply graded rural road. The road has 3 service ramps to a major highway, rt 28n. It also has 1 road that allows a r/l access to burton and a cross traffic access to 28n. I had just started the descent down burton when I noticed the car began to accelerate. I applied the brake twice to reduce speed; it was non-responsive. The car continue to speed down the hill for approximately 3/4 mile. The car began to slow down about 1/2 mile beyond the access road to 28 n. When I tried to pull over to a gravel/weed shoulder I found that the power steering was also out. …”
