“This is the third time within a 2 month time frame that I have been having a service traction system , service theft system , ABS system on my odometer. I had to stop and turn the car off. Then they replaced the wheel barring, then they did the electrical and tire and now it is acting up again and they dont even know what it is this time.”

“While entering interstate off ramp I started slowing down and vehicle accelerated to a very high speed. With extreme brake pedal pressure was not able to slow vehicle down for approximately 100 yards. I had to change 3 lanes to avoid collions with vehicles in front.”

“This has happened numerous times. The first time the check engine light came on, I don't recall the message I actually got; but I took it to a dealership and they replaced an emission control item which seemed to do the trick for awhile. Eventually, as I was driving along some time later, the message reduced engine power came up; and I could feel the engine immediately start to drag. In about 30 seconds to a minute, traction control off or something similar comes up. …”

“We have experienced multiple electrical problems with our 2009 Buick Lacrosse. It first appeared as a bad battery which was replaced. Using the in-car digital readout, we began to see strange voltage readings in the car. The voltage would some times read as low as 12.6 volts and then would start a steady climb up to 14.4 volts. It might stay that way for hours or might slowly drop to the low level. At the low level, we have noticed that multiple items like the speed control and the air conditioning would not work until the voltage was at the high level. …”

“Reduced power/traction control light came on suddenly and reduced car power immediately. This made for a very dangerous situation while passing a truck and entering the highway. The car dropped speed very quickly making for a potentially deadly situation. This problem comes and goes with no warning until it happens. Research shows this is a big problem for GM vehicles especially the 2009 Buick lacross models. It's a disaster waiting to happen if it hasn't happened already. This needs to be recalled asap.”
