2008 Buick Lacrosse: check engine light

Filed Oct 18, 2020 · Acceleration · 40,000 miles · AZ

Once in a while it acts up where it states that it's got low oil pressure even tho it's got plenty of oil,also it has misfired during when this happens. It's like this: I'm driving. Everything is fine until all of the sudden I notice engine light is on also the t/c light comes on and it also states the low oil pressure and the acceleration pedal it acts up. For example, I'm giving gas and it isn't accelerating as much as it should be and it totally fluctuates. I've also had the car misfire and shut off during one of these episodes as well. These episodes of what I had just described comes and goes and actually it stayed gone for a good while now until just a few minutes ago. The guy who sold me this car told me that there'sa recall on whatever issue I'm having with the accelerator pedal (I plugged in fixd tool which tells me what is wrong with my car and gives me two codes the codes being: p: 2138 and codes p: 1125.

First issue car will shut off driving down the freeway doing 60 70 miles an hour it will just shut off and I have to coast to the side and wait and wait till it starts again very dangerous. Next issue is the airbag light flashes on and off I'm assuming do I do to a pressure sensor in the passenger seat which I have a daughter that sits in the passenger seat and I don't know if the airbag is working or not. Next problem are the door locks they lock they don't lock the left rear does not work I have to manually pull it up and push it down if I want it locked the key fob warning is always on my dash saying key fob battery is low I replaced it I replace the key fob itself it just works when it wants to. Next problem the check engine light comes on goes off comes on goes off and therefore I cannot use my remote start if the check engine light is on it has been checked there's nothing wrong with the car nothing shows up if you check the gauges I don't know what to do I paid a lot of money for my remote start cannot use it and I'm in minnesota. I need my car fixed it's reliable it's a good car it's what I drive it's my car I have a daughter's life at stake in my car I expect it to be trusted in the car that I bought after reading all the complaints on the site regarding the same issues that my car is having I am hoping literally hoping that your company is willing to fix these issues in my car and all the other people that are waiting in line cuz this is ridiculous

I had a 6 pack of beer sitting on my passenger seat and my "airbag" malfunction indicator light became illuminated. So I removed the 6 pack of beer from my seat however, the airbag light stayed illuminated. This happened after 5pm so I have yet to contact my dealer as their service closes at 5pm. The car was sitting in the parking lot when this occurred. I found from "googling" this issue that this is a common fault in 2008 buick lacrosse models.

While driving on a side street @ 25mph near the parkway entrance my engine cut out without warning. I was able to coast to the side of the road. The engine cranked but would not restart. There was no check engine lite on or indication of a problem at anytime beforehand. The vehicle was towed to an independent service station where it was diagnosed and found that one of the ignition coils (cyl. 1 & 4) had melted and split and the ignition control module had burned out. (I have retained the old parts for future examination if needed). The cost of repair, parts and towing was $438. It was extremely fortunate that the breakdown occurred where it did because in a few minutes I would have been on a busy expressway and bridge. Note: vehicle manufacture date was sept. 2007 by gm of canada

While driving, the engine light came on, followed shortly thereafter by the traction control light.then the engine began to lose power and the accelerator pedal did not work. A notice appeared on the dash control: "engine power reduced" and "service traction control". If I held the accelerator pedal down all the way to the floor, after about 5 seconds the car began to accelerate quickly. I could then maintain speed by alternately stepping on and releasing the accelerator pedal quickly. Accelerating from a stoplight is a very slow and disruptive (to traffic) process. This has happened multiple times and has failed several attempts at repair. On some occasions, the car has begun to accelerate on its own during this period of malfunction, such that I have had to ride the brake pedal. On some occasions this problem has remedied itself after a couple of days, with turning the engine on and off to reboot. The problem can last for days at a time. I have replaced the throttle body sensor to no avail. Interestingly, I also owned (until last week) a 2007 lacrosse which does the exact same thing, and has also had the throttle body sensor replaced with no luck. I have seen multiple descriptions of this by people online, describing exactly the same conditions and warnings. This is a significant safety issue when it happens, as I cannot safely accelerate in busy traffic, and the car slows down to speeds unsafe for the conditions. I find it difficult to believe gm does not know about this, in that I have had the same problem with 2 lacrosses. Thank you.

Tl* the contact owns a 2008 buick lacrosse. While driving 25 MPH, the vehicle hesitated as if it were about to stall and the check engine light illuminated. The contact mentioned that smoke started to emit from the rear passenger seat where a child safety seat was installed. The vehicle was taken to an independent mechanic. The technician diagnosed that there was an electrical failure. The vehicle was not repaired. The vehicle was taken to another independent mechanic, where it was diagnosed that the coil needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 90,000. The VIN was not available.

I turned the key in the ignition to start the car. Immediately, a very large roar ( like an airplane) occurred just as the engine started. I turned off the ignition fearful of damage to the engine, not knowing what might happen. It would not restart. It was towed to the dealership to have it repaired. The ignition coil had ruptured, ignition module was knocked out. The cost for repair: $800+. Two weeks later, the engine light lit up on the dash board display. I returned to the dealership for investigation. The second repair diagnosis repair required the replacement of the fuel pump, the oil pressure sender pump and the air injector pump ( no charge for this). Cost: $1004.81. When I tried to drive it home, the engine light lit up again so I returned to the dealership. This time there was a need to replace a emission valve.( no charge). Five days later, the engine light lit up again. Diagnosis: code po411, air injector pump malfunction. Will schedule repair next week ( february 14-21) this ignition coil malfunction caused electrical failures to electronic module, the fuel pump, the air injector pump, the oil pressure pump and the emission valve so far, at great cost to the consumer. More importantly, the fear is that the ignition coil rupture and resulting failure could have caused an engine fire. The sound was deafening and felt like an explosion. I have never experienced this kind of problem with any other of my automobiles. It was a frightening experience.

Engine light comes on and car goes real slow, then it wont move. Doors wont lock/unlock with remote and they wont automatically lock/unlock in park or when you start driving. Air bag light for passenger side comes on and off, when someone is sitting there. Back tires wore off on insides had to replace them. I don't feel safe anymore. Dealer said I should be notified of recalls so it can get my buick repaired.

While driving approximately 25-30 MPH the engine died, steering failed; I was able to come to a safe stop. The vehicle would not start. It had to be towed. Later found out the ignition coil was cracked (part # 10472401) , ignition control module replaced (part # 19245558) & 15a fuse were replaced. I had been experiencing a gasoline smell in the vehicle for months. I had it into a gm dealer 3 times for the issue without resolution. I was told by the repair station that they were amazed the check engine light had not come on before the failure. Apparently the vehicle was only firing on 4 cylinders.
