The car continues to have serious engine issues. I keep getting a service Stability track and Engine Power Reduced warning. It has happened to me on the expressway and the car will not accelerate past 20 miles per hour. I had the car repaired on October of last year (3 months ago) and the issue persists. I decided to research online and this seems to be a major issue going on with Buicks. It sounds like GM has done nothing to remedy the malfunction. Many people state that even the dealers can seem to fix the issues and have no clue as to why this happens. This is a serious and life threatening mechanical failure that needs to be addressed.

I have known issues w/my 2010 Buick lacrosse CXL ABS light

I get Reduced Engine Power and Service Stabilitrak messages. Engine Code P2138 is prevalent. The car will not accelerate, nor maintain highway speeds, forcing the driver to pull off the road and shut off the car. The warning message returns under normal driving conditions. This code points to several components [Accelerator Pedal Position (APP) Sensor, Throttle Body Assembly with Sensor, Manifold Absolute Position (MAP) Sensor, etc...] All of which I have replaced. It is rumored that General Motors knows that it is a problem and the true fix is to replace the wire(s) and seal or replace the connector. Refer to GM Technical Service Document 070604019F

Electronic Stability Control Systems (ESC) activates a couple times a week every other month for several years. Multiple Warning lights flash, needles on two dials rotate erratically resulting in sudden changes in vehicle handling and deceleration, and on wet roads which cause me difficulty in maintaining the vehicle's desired path of travel and desired vehicle speed, and could result in a crash without warning. I have a video. Its scary. Had it looked at twice and paid a lot but it keeps happening.

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.

While driving city streets in a snow storm, I was unable to defrost the rear window and melt the snow off of the heated side view mirrors. I literally couldn't see anything behind or next to me. When I press the defroster button the light indicates that it's on but nothing happens. There were no warning indicators illuminated. I took the vehicle into the dealership twice for this problem and they said that both the rear window defogger and heated mirrors work off the same button and needed to be reprogrammed - but it never seems to work when I truly need it.

My Buick Lacrosse was handling just fine until I put a heavy piece of luggage into the trunk. I got back in the car and it wouldn't start. A message was on my dashboard saying there was a power steering problem. I was at the airport, so a tow truck driver was on the scene within minutes. The tow truck driver jumped my car. He handed me the trim cover that covers the battery. I'm not sure if he took it off, or whether it came off when I put the heavy suitcase in the trunk. I put the trim cover in the back of my car and drove off. The car then stalled when I put it in reverse to back into the driveway. It wouldn't start again, so I jumped it. It worked and I drove to my mechanic. Mechanic said my battery was fine. They checked the error messages. They couldn't figure out what was wrong so they sent me to a dealer. The dealer couldn't figure out what was wrong and said to come back if it happens again. For about two months the car would randomly not start or stall. Several days could go by with it working just fine. At first, when it stalled it was only when I had just started the car or put it in reverse. But then the vehicle stalled while I was driving on the interstate, at the top of a long hill, in a construction zone. I was able to coast down a half mile or so until I arrived at an emergency pull off zone. The power steering went out so the steering wheel was tight but workable. After pulling over, I tried starting the car again but it didn't work. I had a self jump start kit, and was able to jump the car again. It started back up and seemed like nothing was wrong. But about five minutes later it stalled again. Fortunately, I was by another emergency pull off. At this point, I put the trim cover back on the battery. And the car has worked fine for several months. The car should not start and then randomly stall if the trim cover is off.

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.

As im traveling to my mothers house on August 27 2017 my engine just completely shuts down and wouldn't start back up. The same week it was having problems starting or wouldn't turn over to start. My daughter drove my car to O'realiys auto part store to get something for her car, get in to leave and it wouldn't start. A mechanic from the store hooked it to the diagnostic machine and it read a delay in the start up. He start moving a couple of wires on the starter to see if that would help and it did. He told my daughter don't cut it off until you get home because he may do it again and suggested I put a new starter on it. I took his advice and bought one and had it installed the same day. When done it started with no problems and the next day while driving is when the engine shuts down while driving. I looked on the internet for problems with a 2010 Buick lacross and I was shocked that people were having the same issues with their Buick. This is very dangerous and is a serous matter. Someone or a whole family could be killed because their Buick has an manufacturing problem and Buick is doing nothing about it. I am aboustley scared to drive this car with my family after reading many people problems like mine. Please help!

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.
