2005 Buick Lacrosse: sudden loss of power

Filed Oct 8, 2016 · Driver assistance · 115,000 miles · OH

My car shuts down while driving. My dash will display "service traction control system, reduced power, starting disable" I must pull off the road; car shuts down, now it has trouble restarting after this occurs. My computer doesn't retain the codes for this issue. My dealer mechanic & personal mechanic cannot find the problem. Have spent $1000 within the past 2 months on this. Still not fixed. Dangerous to drive this car. Occurs intermittently; no pattern. I am paying for a car I cannot drive. Very upsetting. Please help.

Pulled into parking lot and lost power steering. Lots of clunking and grinding just prior. Mechanic says power steering hoses, rack and pinion and tie rods. Yet another problem with this vehicle. Gm was aware enough of the problem that they put a supervisor on the line but said that it is out of warranty now, so it's not their problem. Going to try to work with local guys to get out of it. Not sinking another penny into this car. If this had happened on the highway, I'd be dead.

Traveling on interstate 57 during daytime hours. While cruising at 73 miles per hour in the right hand lane, the vehicle sputtered and lost all power. I coasted to a stop off the side of the road. I restarted the vehicle and everything seemed ok, so I continued on. A little later it sputtered again and started losing power. The power came back before it came to a complete stop. I called on star for a diagnostic check and they told me I had a fuel system problem and that if the car would run to continue that it was not a safety issue. They told me to take it to a dealer for repairs when I got home. I took the car worden-marten service center for repairs on march 23rd. To repair the car they: 1.replaced cat converter and oxygen sensor 125cgmpp- $750.47 a second incident occurred while traveling on interstate 57 during daytime hours.

2005 buick lacrosse was bought used with slightly over 44,000 miles back in may of 2008 and was taken to the dealership for acceleration and transmission shifting issues several times since purchase. Car would not accelerate, losing power while going up hills, bogging down while slightly accelerating to pass, and the transmission would shimmy between 1st and 2nd gears, and clunk when coming to a stop. Naturally, the dealership played the guessing game replacing the catalytic converter, the torque converter and sensor, and even re-programmed the computer, and could no longer duplicate any problems once they had run out of their options two months ago the car developed a clicking noise while turning the steering wheel either direction, the dealer was able to determine within an hour that it was the intermediate steering shaft and proposed lubrication to resolve the issue for a cost of over $300. Sounds like they were already aware of this popular issue.

My 2005 buick lacrosse has had a problem with acceleration since I bought it used in 2006, if you step on the gas between 50 and 60mph the engine dies, no warning lights come on and you have to idle out of traffic until the system comes back on, I took it to buick and they told me they couldn't find anything wrong, to this day you have to watch your speed when passing so that you do not lose power.

Upon entering the highway and approaching the 55 MPH speed limit the car seemed to stall. The engine acted like it lost all power. Letting up on the gas pedal caused the engine to regain power until the gas pedal was pressed again. I did this numerous times until the car finally died and I had to pull off the road. After the long line of cars passed by I got the car started and kept it in first gear until I was more sure it could keep running. It behaved normally after that. When I got home my wife confided it happened to her once too.
