“Takata recall we bought a used 2005 Buick Lacrosse for our son in april 2016; at first it ran perfect and then we noticed a thump when changing gears (automatic transmission). Two weeks ago my son was going to the store and drive stopped working. Now it is sitting in the yard and will only go into 1st and 2nd gear and reverse. It will not go into drive.”
NHTSA complaint #10875899, filed 2016-06, 143,000 miles“While driving the car down the road it will randomly shut off. Giving no indication other then dimming lights. Neither the dealership or the garage I went to can explain it. The power steering doesnt work and has almost caused me to crash on the highway and town roads.”
NHTSA complaint #11206927, filed 2019-05, 150,733 miles“I smell something like burning wires. The transmission light is on. Automatic shifting jerks. I am afraid of being stranded somewhere. I am 70 years old and need my car to be reliable.”
NHTSA complaint #11048441, filed 2017-11, 83,371 miles“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.”
NHTSA complaint #10280897, filed 2009-08, 21,000 miles“While sitting at red light would not move on green, had checked could not find problem. Then during merging onto highway lost all power, almost got hit. Then starting surging. To dealer again, could find no problem. Kept acting up, it was the transmission again. This is the 2nd rebuild on this very much used transmission model in GM vehicles.”
