Air bag is on says it needs checked and also some electrical problem with the transmission that is causing the car to jerk while accelerating

- Jersey City, NJ, USA

Over the two years, while driving, the service stabilitrak warning light comes on; the ABS & park assist lights flash on and off; my RPM, speedometer, & temperature gauges go haywire; and the engine loses power causing the car to jerk. This happens while the vehicle is in motion at various speeds. You never know when this will happen. I have been put in dangerous situations when this happens while driving including on side streets and major highways. The check engine light also comes on and stays on throughout the rest of my drive. You can go sometimes weeks or months incident free and with no check engine light on. Then out of nowhere it happens again. I have taken my car to the dave sinclair Buick / GM dealer located in St. Louis, Missouri on 4 separate occasions over the last 2 years for the same issue yet to no avail it is still not fixed. The dealer's tech said my cars problem is almost certainly electrical. So far they have found multiple codes for ECM (they replaced at my cost) & tcm lost communication PCM malfunction & other communication issues (they reprogrammed). They have driven the car and have duplicated the issues but to this point have not been able to pinpoint the problem but said that it's electrical. I contacted Buick and chatted with an advisor (a copy was uploaded) who basically told me there is nothing that they can do. A quick search of the internet will show several other Buick owners experiencing the same issue as I describe. This is a very dangerous situation & I don't feel safe driving the car since I never know when the car will suddenly lose power, thus causing an accident.

When I purchased this vehicle with the powertrain warranty still intact I had the check engine light come on several times. Took it to the dealer and they said it was nothing and had it reset. Over the past few years I have had it come on more frequently since then and now it has been on for over a year. With frustrating amounts of time spent to try to determine what the issue is I finally found out the timing chain and seals need to be replaced. One of the symptoms is that the oil in my car is not being distributed properly. This would also be one of the reasons I have had to add oil before every 3000 mile oil change because all of a sudden my car will start running hard and acceleration is harder. Many times I would only put 1500 miles on my car and my oil wold be bone dry. Put oil in and it gets better. If I wouldnt have have caught this my engine would surely have been blown. So now 3 years later I am stuck with this issue which should have been found while under warranty as all the same issues were occurring then and now. I cant seem to access my Buick account online surprisingly but it did have all my service records proving my attempts with them. This is not the only issue, I know that the same vehicle just with a samller engine has been recalled for the same thing. Why not the bigger engine? I now have a $2000 repair to make not including the several hundred it took to determine the issue. Something should be done about this issue that is happening in Buick of this age and newer because it is happening alot.I have many service receipts showing the process of this and also the diagnosis today and theone I will be getting tomorrow to confirm and will be glad to forward on to you if needed.

On Friday, July 1, 2016 I was traveling down a 2 lane road with my cruise control set when my car suffered a loss of power. The engine still was running, but apparently my transmission lost the ability to power the car. I was able to park on the shoulder of the road, and eventually, towed to my mechanics shop. Yesterday I was told the problem was a faulty transmission control and it will cost me $1060 to repair. I was also told that this is a common enough problem that Buick dealers keep the part in stock.. if it is that common of a problem, and cars are losing power on the road, that is a safety issue and should be subject to recall, instead of taking hard earned money out of owners pockets to fix! I might add that this car has less than 68,000 miles on it!

The transmission does forceful jerking while going 30-35 mph. Also was told that it was normal as GM designed the transmission this way. I find that hard to believe.

While driving on busy freeway 2010 Buick Lacrosse loss all power, wouldn't accelerate, couldn't do anything besides panic and coast off freeway to meridian, very unsafe and scary situation. But I was told it was a module switch that didn't tell the transmission what to do. But a new transmission was replace prior to that incident and still having problem afraid to drive car, it might shut down again while driving just feel unsafe to drive the car, im terrify of what would happen next.

Today, while driving my 2010 Buick Lacrosse on atl highway 75 South, my car's transmission stopped working. I could not accelerate and had to coast off the freeway. The car stopped moving as I rolled into a driveway. It would not go any further. Also, when I first purchased the vehicle, the dealership repaired wiring from the transmission pump and replaced the defective pump because the steering was loose and sloppy, and everytime I made a left turn, the car made a loud noise. Also, the passenger side lock jammed and would not open.
