Shortly after purchasing this vehicle I found that while rounding a corner the power dies and I lost control of the vehicle since I had not power steering or brakes. I was able to steer the car to the berm and waited until power was restored. This has occurred many times. Upon checking with the dealer I was told buick is aware of the problem, but there is no recall. Then I began having alot of problems with the stabilitrak - the car loses power and surges. Again the dealer told me they are aware of the issues with the lacrosse, but there was no recall and the cost of repairs was over $2000.
2012 Buick Lacrosse engine complaints
Page 3 of 3: complaints 41 to 52 of 52, newest first, as owners wrote them.
Vehicle was excessively rough in transition between hybrid and engine power and would jerk as if someone had placed the vehicle into park while moving. Vehicle lost electrical power to AC, radio and other accessories. Vehicle shutoff and had to be stopped and placed into park before it would restart. Vehicle lost power steering and the steering would stay locked in position until the vehicle rolled about 10-15 feet or until the vehicle transitioned to engine power. These condition repeated multiple times in a two day span, the vehicle was taken to the dealer for service. The dealer replaced a solenoid and an engine mount stating they had excessive wear. The vehicle now stays running, but I continue to have issues with the rough transition between modes. My concern is that this is the root cause of the excessive wear on the other parts and that the vehicle shutdown and steering loss will occur again. If it does, the damage to property, injury, or loss of life could easily occur given the lack of drivability and loss of control of the vehicle when the condition occurs.
The car was 5 months old. We were going downhill in the mountains of wv. The car seemed to lose power of propulsion and acceleration, so we coasted to a stop on the side of the interstate highway. The car would not go forward or accelerate at all, although the tachometer would move when we accelerated. This was a frightening experience because of the traffic on the highway. We could have easily been hit by a truck. The service people found no defects. For the past two years we have not lost power, but the car's transmission lurches when we stop accelerating and slow to 32 MPH. This gives us a ride that is not smooth, and at times is uncomfortable. Others have reported the same issues online, and we are concerned about safety while driving our car, especially at high speeds and on highways. The gm dealership service department denies there is a defect that can be fixed.
For about 6 months I have been having problems with stalling after slowing and then accelerating. The first 3 times were not as frightening as the one that occurred on 7-7-2014.returning from a trip to new orleans,as I exited the interstate and began to ramp off, the car stalled to the point of no control of the steering. It lurched to regain speed and finally recovered. We took it to the dealer on 7-10-2014 and they did diagnostic check and found no obvious problem which is difficult to do when the problem is intermittent. I am afraid of driving the vehicle until it is repaired. The dealer said to bring it back if the problem occurs again. My question--what if the next time it causes a crash? Can you please help me get resolution as my warranty expires in feb. 2015.
Diesel fuel was accidentally fueled into the car at a gas station having a "hybrid" pump--one having two nozzles. While this was a mistake on the drivers part, a diesel fuel nozzle is designed not to fit into a car with a gasoline engine. This error should have been impossible. On this buick, this is not the case. A diesel hose can be fitted into the filler pipe and left there unattended and will fill the tank. The safety danger in this is that the car will stall when the unleaded fuel already in the fuel lines runs out and the engine receives contaminated fuel. We were lucky and the car reached home first and then could not be restarted. Otherwise, the car would have stalled on the road, the power steering would have failed, and the car could easily have been in an accident. This condition cost $1145 to repair. Updated 1/16/15
This incident has occurred 4 times in the 17,000 miles now on the vehicle. Each time I was driving on or off a ramp. Speed estimate 30 to a max of 40 MPH. The car starts to die and I have to struggle to get off to the edge of the road so vehicles do not hit me from behind. It just loses all power but doesn't quite stall. Once I pull over, take my foot off the gas, the engine recovers and has ran fine. I do believe I caught a glimpse of the "red light" that came on 4/11 as I was going up a ramp to my doctors office. The light doesn't come on all the way because the car and never totally dies.........it appears to be a car with swerve marks behind. I took this car in the same week on 4/07 and they said the car is operating "as designed" and couldn't locate any problems. It seems to run great except for the 4 mishaps and it really scares me that someday I wouldn't be able to get off the road or a car will hit me from behind. There has to be a problem. I don't drive fast and I am definitely not skidding around the ramp. At age 61 I might not be doing the speed limit even. Help me?
Since I purchased the car in june, 2012, there have been three (3) incidents where there was a gradual loss of battery charge, the vehicle would not start, and the illumination of the malfunction indicator light comes on. The most recent incident was this past saturday, on november 16, 2013. My car is also equipped with e-assist. I do not know if there is a problem with the generator control module, or similar device. Each time a certified buick repair service claim they cannot find anything wrong with the vehicle. Thanks god I have always been in a safe place when this has occurred, and so far there has been no fire in the trunk of my car, which I understand might occur. Thanks for all of your assistance in regards to this urgent matter. Updated 12/16/13
I have had multiple issues with my 2012 buick lacrosse, it started sooner than this with my air deflector falling off at 75 MPH and almost flipping my car. This time on july 30th my vehicle went completely out from the memory loss, the transmission just stopped working and I was stalled in one of the busiest intersections in my city. As I was trying to get my vehicle to move again the light turned red and an 18 wheeler almost broadsided me. I found out that back in may a safety recall was sent down on my vehicle. The ones with easiest the battery in the back can catch fire and cause problems. I did not even get my notice until I had picked my vehicle up and gm said they weren't going to send notices until they "had a problem" well parts on national back order due to the problem seems like a huge problem. Gm keeps giving me excuse after excuse and does not want to help me in all the problems I have had. My air deflector falling off they said could not happen, I said it did and it is gone, can't reproduce something with nothing there. In front of my neighborhood a cadillac escalade dropped his air deflector too, same side dropped, same side twisted off, nothing in the road to cause the problem and I have the proof yet gm doesn't care and still says it doesn't happen. My mechanic said if it is not installed properly they will just fall off, the air deflectors on gm products are held on by only 2 bolts, the other spots have never been bolted on, now I have a damaged vehicle and gm says it doesn't happen. I have almost been killed three times and my daughter once in this vehicle, how normal is that? Please help!!

We were on I 35 traveling about 70 MPH when the motor suddenly lost all power. After about 30 to 45 seconds some power seemed to come back and I was able to drive the car to the service road. External temp. Was 93 and but there was no working air con inside the car. I called onstar. They ran a diagnosis and said my car was not working properly and should be taken to the dealer. I started to drive to the dealership but the car motor stopped completely. No power of any kind. Could not restart. Could not move. The car had to be towed. The dealership diagnosed the problem as a broken serpentine belt. They said a recall was issued 12 days after I bought the car. I never received the notice. I have written to buick and to general motors and requested an explanation. Neither have replied.
