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.

I was getting on the on ramp for the interstate and gradually attempting to gaining speed to but my vehicle would not pick up speed.I pressed the gas pedal to the floor with no pick up. Then all of a sudden my vehicle began to pick up speed. When the vehicle got up to approximately 60 mph it began to do the same thing again I had the accelerater pedal to the floor. I could here the vehicle idling and after some time had passed it began to pick up speed again. I've had my vehicle for four years and have kept up with the maintenance at the dealer ship. I have paid for diagnostics several times at the dealership to no avail. I took it to the dealer but they found nothing wrong with it. I have taken it more than 5 times in an attempt to rectify the problem with no success. It's not a constant thing, however it is quite dangerous as well as unsettling not knowing when or where my safety may be comprised in this vehicle. This is my second Buick Lacrosse which has had problems of this nature. I was hoping my problems with my 2005 Buick Lacrosse was an isolated incident but I'm beginning to think perhaps it wasn't. maybe this can all be attributed to just poor workmanship with inferior product manufacturing.

My car currently is parked in my garage and there is a fan blowing. It has been blowing the past hour. I read on the internet that other cars are having a similar issues. They state the cause is the water pump. I plan on taking my car to the shop tomorrow for a evaluation. I hope that I don't wake up tomorrow and the engine fan is still running.

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.

I was driving on the freeway this morning doing about 60mph in traffic and all of a sudden my car lost power. The dash or the dic went completely blank, but not before all of the chimes, and the caution alerts appearing and then I started to loose speed. Fortunately I was able to pull off to the side of the freeway. At that point I put the car in park after a minute I restarted it and continued to drive to work. This same incident occurred back in November of 2014. Coincidently I was on the freeway then too. But when I called the dealership back in November when this first happened they informed me that there was nothing that they could do unless I was able to recreate the issue. But of course I can't recreate the issue and now four months later it's happening again. I don't understand why there has not been a recall for this. Especially considering I have read other complaints for the same reason.

Engine quit causing brakes and steering to become inoperative. This is the 5th time this has happened. I have previously reported this to NHTSA and General Motors.I never received a response from GM. I took the vehicle to my dealer and the only thing they did was reprogram the vehicle but apparently it did no good. I think the problem is in the ignition system.

I moved my car out of the driveway so my neighbor could plow. He said he smelled something while I was in my car across from our driveway. I put the vehicle in park, pushed shut off/turn off button, vehicle instantaneously filled with dark rolls of smoke coming from the passenger side from the front of the vehicle under the hood. I grabbed the door handle jumped out. My neighbor came running telling me to disengage the hood, I complied. Flames shot up and out from under the hood as it was being released. He threw a lot of snow on the fire extinguishing it. We inhaled the most obnoxious fumes from any automobile I have had the displeasure of having in my company. Car will not start. After this, my husband came out to see what all the yelling was about. My neighbor explained it to him and he unhooked the battery. The car is still parked at the scene of the fire. Today is 2/22/2014 and no insurance adjuster has been here yet. Our town fire department was called and the fire chief assistant came the very day incident occurred and filled out a form, I contacted Buick and I have a claim number and am awaiting further contact from them. Our town highway department placed cones around my vehicle.
