2010 Buick Lacrosse: check engine light

Filed Jul 14, 2021 · Electrical · CA

I was driving on the 99 freeway when my car turned completely off! I could have been killed!!!!! The check engine light came on and service stabilitrak was on the screen. Then it would not start. There was no warning at all. I got it fixed (so I thought by one mechanic) and it happened again. So I took it to the Buick dealer and they fixed it(so I thought) and it happened again. It is now at the Buick dealership and they told me it is the control module on the computer and quoted me 996 dollars!!!! I looked up online and found that other people have had the same problem with their 2010 Buick Lacrosse. Seems to be a manufacturers defect and needs to be reported and recalled.

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 buicks 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.

Takata recall purchased used in may 2015 with approx. 45k miles. Since I have purchased the car, I took it to a dealership in kokomo in to have it looked at for the park assist. What happens is when I am driving down the highway, usually with the cruise control on, going 60+ down the highway, the park assist comes on, all the lights on the dashboard flash and all the sounds go off in the car immediately disabling the car. At that point, the car disables itself and you cannot push the accelerator, making it difficult to get off the highway. You have to immediately pull off the highway and turn the car off. After waiting a few minutes, you can start the car up and the engine light will be displayed. The engine light will stay on until the next time you start the car and then goes off. Over the last year, I have had this happen approximately 20 times. The dealership in kokomo couldn't find anything wrong with it and they stated they cannot try to find something wrong with the car if it isn't happening when I bring in the car. I moved to tennessee the first of january 2016. It has happened to me since living here again so I took the car into parks auto service in columbia tn. After having my car for 2 1/2 weeks, they are unable to find out what is wrong with it. I have been very fortunate thus far to not get into a bad wreck losing my life or crashing into someone else and killing them. At some point, this will cause a major wreck and lives could possibly be lost or someone could possibly be disabled the rest of my life. At what point does this have to happen before buick will find an answer for this? I need help on this as there are no mechanics that can resolve this issue.

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.

Approximately two months after purchasing a buick lacrosse I started to experience the vehicle shutting down when the car was parked or idle. Shortly after the check engine light came on. I then took the vehicle to the dealer and they claim they could not find anything wrong with it. I decided to get a second opinion so I took the vehicle to another certied repair shop and they suggested that I get and upper engine flush. Supposedly because this type of vehicle is known for massive amounts of carbon build up. So, I got the upper engine flush on my vehicle but the very next day the check engine light came on again. The. Machanic advised me that it would take more than one engine flush to fix the problem. So after not two but three upper engine flushes the problem of having the check engine light intermittently display is not resolved . No one can seem to find a diagnosis for my vehicle problems not even the dealer. Most recently, the dash board display light periodically goes out, and an unfamiliar noise is coming from the driver's front tire. Once again, I have taken my vehicle to a certified machanic and the issue is not detectable.
