general problems of the 2010 Buick Lacrosse

I purchased a vehicle August 2, 2024 from kingdom auto sales. The car was inspected July 2024 in which it passed shortly after the car wouldn’t go over 40 mph. It would say it’s an over speed. The car runs hot and the parking assist light won’t go off may 25, 2025 I was driving on the highway in the car lost power and the speed was reduced after getting off the highway lost control of the steering wheel due to the stability and hit a guard rail. No reports was made. I contacted the dealership in which I haven’t been contacted and problem not resolved.

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 on.

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.

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.

Everything I turn the car on; its saying "ac turned off due to high engine temperature and my car isn't running hot and my ac semi working. Electrical systems isn't working properly because I can't turn my radio or ac on.

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.

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.

Driving at nite to er and on way I thought I must have hit ignition button but car just locked up lost all power. I called gm they got back to me said they would be sending someone to see car. I did reck car not to bad but bad enough to take hole front bumper off. I am so mad because I thought I was crazy thinking car would just loos all power and even locked me in car could not open door thank god window was down. But they said they were coming to see me and car but never did.

I can be driving down the road an all of a sudden the meters start going up an down an then it will say car parking assist is in then the car will shut of this can really cause a bad accident what if I'm in the car with my kids one day an the car shuts of an I have nowhere to pull over.

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.

I have taken my car to several shops in regards to my headlight and no one can figure it out. One headlight in out which are my low beams. The entire car has been rewired and still doesn't work. It pops on and off when it wants to but still the low beam headlight does not work.

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.

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.

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.

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.

2010 Buick lucerne rear fuse block malfunctioned and caught fire.

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.

There are blind spots on right and left windshield. Also when the temperature is below freezing the heated mirrors and rear windshield do not defrost until the vehihcle is totally warm and driven 50km.

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.

Was driving down the interstate and everything in the dash flashed like when you first start the car. I didn't want to take my eyes off the road, but I think even the speed dial went down and up, again like when the car starts up. Then the little information window in front of the steering wheel window flashed several things including "three keys programmed" and then it stayed on "tire monitor on" or something like that. It had previously been on the mph setting, so I had to roll it back to the mph setting. The car itself drove fine, but I was scared it would do something bizarre and I was in heavy traffic. It was like it rebooted itself.
