In 2018 the air went out in the vehicle and then the abs light cane on. A few days later the check engine light was displayed and then the next day the battery completely died. I took it to the shop and had it fixed. They said that battery was missing a cell and they replaced the battery, fixed the air conditioning basically fixed all issues. Fast forward to a year to the date the same issue started again in that order. The car has officially cut off and I searched and there are no open recalls coming up for my VIN number.

Warning lights on dashboard randomly coming on and off. Including power steering light, check engine light , service stability light. Vehicle when first turns on shakes and vibrates then goes to normal after a few minutes. No low fluids or problems found from certified gm service.

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.

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.

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 replaced lt ft speed sensor and told me that they could not fine why the engine light was on. Last week I'm getting same problem with the stabilitrac and yellow/orange slippery light came on.

A couple months ago it stalled, while my 17 year old daughter was driving it.  there were no engine lights on.  this happened to me a couple times and to my husband.  it takes about 2-3 minutes before you can start it.  the engine light will come on when it stalls, but goes off when started.   without the engine light on, there is no the code to find out what is wrong.  one time it stalled and when started, the engine light stayed on. .  my husband took it to the gm dealer and we were told it was the battery.  we bought brand new battery and installed it.  same day the car would stall.  I have read many stories about this problem with the 2005 Buick Lacrosse.  people seem to have multiple problems it could be, but when replacing parts doesn't fix the stalling problem.  I called gm and got a case number.  we are told to keep driving it until the engine light stays on so we can get a diagnosis.  when the car stalls at 20 mph or 55 mph, you have no control of the vehicle.  gm won't do anything until there is a diagnosis.  I asked gm if I could get a loaner car until my car is fixed and they just say the warranty is over, or it is a seven year old car, and of course won't do anything until it is diagnosed. ??  it is very dangerous, especially if no warning lights come on.  I don't dare to drive it.  my husband is the only one who drives it.  we have another vehicle, which is gas hog that I have to drive.   I can't afford a new car.  I also can't afford to keep buying parts that don't fix the problem.  my car is paid off.  I am disabled and can't work.  just waiting now for disability benefits.  my car has low mileage and is in perfect condition.  I am unable to drive my car that is registered and insured and gm will not help me.  I think it is dangerous to tell us to drive the car until a engine light comes on.  any resolutions?.
