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.

Over the past several months, 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. I never know when this will happen. On 3/18/16, I was put in a dangerous situation when this happened while driving across the state of florida on a 2 lane highway that had no safe place to pull off the road. The check engine light also came on and stayed on thru the rest of my drive. Two days later, the drive home was incident free & the check engine light was gone. On 3/22/16 I took the car to a gm dealer; showed the service tech a video of the events happening as I was driving and a letter I got from gm regarding a possible throttle sensor problem that causes reduced power and malfunction indicator lamps to appear. The gm dealer tech said my cars problems had nothing to do with gm's letter and he was 90% sure my fuel injector needed replacing. I took the car to my personal auto mechanic for 10+ yrs, who works for a very reputable company, for a second opinion. Since the codes had been cleared by the dealership service dept and the car checked out ok my mechanic said to drive it and bring it back if the problems occurred again. It recently started happening again & my check engine light came on so I took the car to my mechanic who found multiple codes for ECM & TCM lost communication PCM malfunction & other communication issues. He drove the car and experienced what I was explaining was happening. My mechanic couldn't pinpoint the problem but said there was no problem with the fuel injection system; that it's electrical. He suggested we take the car to another buick dealer to have it checked out. This is a very dangerous situation & I don't feel safe driving the car since I never know when the problems will start happening.

Three days ago, while on a trip from the west coast of florida to the east coast of florida; and while driving on the highway at 65 MPH, the warning bells started dinging and the messages: service stabilitrak, ABS, and park assist off kept flashing off and on; the car began jerking and losing engine power; the tachometer, speedometer, and temperature gauges were jumping around all over the place; and the check engine light came on. (a video of what occurred was taken to show as proof). I managed to pull off the side of the road, turned the car off and sat for several minutes, then started the car again. Less than a minute after I got back on the highway, the same events occurred again. After at least 30 minutes or more of the car continuing to malfunction while driving; it suddenly stopped giving me warning signals and engine power seemed to stabilize; however, the check engine light remained on. Once I reached my destination, I didn't use the car for two days. My return trip home, which was approximately 140 miles, was uneventful; however, the very next morning on my way to work, while sitting in traffic on the expressway, the warning bells suddenly started ringing again, and the service stabilitrak and ABS lights came on. Fortunately I was able to make it to work and called the buick dealer to bring my car in to have it checked. In the past few months, this problem has occurred 3 to 4 times, but each time only lasted moments and never to the extreme that it did . I received a letter from buick about 3 months ago that pertained to such issues and loss of engine power; and the letter stated that the car should be taken to the buick dealer and repaired at no cost. This is an extremely dangerous problem that needs to be addressed and resolved immediately.

Took my car in for regular service, my wife drove it home, the car died after 8 miles. She slowed for stop light, car suddenly died. Electrical system went crazy, car lost power, died. I backtracked to help,. I tried starting the car but didn't have any compression. I called dealer, they sent toll truck. According to them, they checked it, drove it a few times, said couldn't find anything wrong, called gm for help. The dealer's service rep said gm told them heard of similar incidents in lacrosse. Gm recommended they apply lubricant cables connecting to ECM. Did so. Had 3 people test drive car, said operating fine. Received call from dealer stating problem corrected,car good to go. Picked up car in company mechanic friend. Rep explained what they did, checked all electrical circuits, breakers, connections, etc and everything appeared to be working fine. Told him that my wife didn't feel safe driving the car now because of incident and he said car should be fine for at least 5 years. I asked what if fix ididn't work? He said that it would probably require a new ECM. Well, car died again yesterday, april 4, about 1:30 pm while driving with my wife to our son's house. Was going about 40 miles/hr after exiting highway, car starting stalling, jerking and all of the console lights were going crazy. Check engine light went on, a service stability track warning and the key symbol appeared on center console, it died completely. Tried restarting it but it wouldn't. Waited for traffic to pass, then I rolled car backwards toward the curb to get out of traffic lanes. I waited a few minutes and then started the cart again. I went a few hundred feet, then it died again. I did this 3 more times until getting to my son's house where I was able to park it. I called the dealership about 20 minutes later, the service department had already closed.

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.
