Buick Lacrosse warning lights comes on

Filed Jul 10, 2026 · Brakes, Engine · OH

2012 Buick LaCrosse V6 (Fairfax Plant). The vehicle suffered a sudden, complete loss of engine power and forward propulsion while traveling at highway speed, cutting off mid-drive with no warning. This occurred alongside a persistent StabiliTrak malfunction; the dash showed repeated "Service StabiliTrak" warnings before the failure, then turned bright orange with multiple warning lights and a message instructing me to activate my turn signal and pull over before RPMs dropped to zero. Because power cut out instantly, my [XXX] son (passenger) and I were trapped in the center lane of a dense, multi-lane highway. I was forced to dodge high-speed traffic and coast the dead vehicle across multiple active lanes to reach the shoulder, creating an imminent collision risk to us and other drivers. We were then stranded on the narrow shoulder awaiting a tow, with traffic passing within feet at highway speed. Both my son and I have CMT2A (Charcot-Marie-Tooth disease), a neuromuscular disability limiting mobility; we were incapable of quickly evacuating the vehicle or reaching safety up the embankment, leaving us trapped in a highly dangerous position. No official inspection or diagnosis has been performed yet. My dash displayed the same "Service StabiliTrak" warning referenced in the federal safety agency Campaign 11V404000, though my VIN was excluded from that recall, and my failure went beyond the handling/deceleration issue described in that recall to a complete loss of propulsion.

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.

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.

As driving at 50 miles/hr on suburban main street, engine lost complete power. All warning lights came on at same time along with check engine icon. My buick lacrosse had no acceleration, no power steering, and no power brakes. The car had no previous warning. No previous reduced performance with engine. No problems with gas economy. Absolutely no warning this would happen. Car still had electricity since speedometer still reading and radio on. After turning off car and restarting no further problems. Gm states no error message in computer. However, this is our second gm car to experience a reduced engine scenario. This time however, it was not reduced just completely off. This is a major safety concern! What if it occurs on the expressway with fast traffic. Luckily it was a local, but busy street, and a sunday. I cannot believe a government agency has not held gm accountable for this problem. A car with sudden power loss is a major public safety concern. Luckily again I'm an experienced driver with a similar incidence in another gm vehicle and knew if I hit the brakes I was a sitting duck. How can a car lose power and multiple posts on internet and no recall ? Our buick only has 30,000 miles.

I was driving to work using my normal driving route in the morning about six am . The conditions were dry and clear. This route has no serious road hazards and is approximately 13.5 miles in distance. I rolled up to a traffic light to make a left turn. Upon waiting for the left turn arrow to come on the car stopped running. The engine shut down .... None of the lights on the car would work and it would not restart. I pushed the car my self into a gas station entrance with some difficulty I will say. I am a big person so it was not that hard to roll this car a few feet. I removed the key and got out and opened the hood to check the battery connections. They were connected and tight. I shut the hood thinking to myself what I should do? So I tried to start the car with the automatic key fob start sequence. To my surprise it started!! All lights and gauges were working. I put the car in drive to complete my drive to work. I had about 1 mile to go. As I drove away the head lamps shut down. Along with the turn signals and possibly the brake lights. I arrived at work and parked leaving the car running. I attempted to use the switches to turn the head lights on but had no success . No lights at all no gauges at all. Later that day I was leaving work and everything operated on my drive home. Safe to say I am a bit pissed off. I was assured that this car was not part of the recall by my dealer o'reilly buick of newtown square pa. When I purchased this car it was listed as 'gm certified used car'. Looks like after I am done with this repair, this car is going to be traded in. Along with this recall there has been a few major electronic repairs to this car. Along with rear alignment issues that were present when this car was assembled. I am done with gm!

Car was parked in garage for 10 hours. Found with all lights inside and out flashing. Remote entry didn't work. Car wouldn't start. Key stuck in ignition. Overhead light and wipers turned on and off on their own and were making a clicking sound. Trunk popped open on its own, then when shut wouldn't open again with the latch over license holder. Onstar didn't work and when called they couldn't "find" my vehicle for diagnostics. Called for a jump start- jumped with battery pack, started easily and ran 5 minutes then went completely dead as soon as unplugged from power supply. Would not restart. Towed to dealer who is telling me they cannot find anything wrong with my vehicle. I will not be taking this car back until it is fixed. Huge safety concern. Couldn't set parking brake or get onstar or even get key out of ignition while all lights flashed and clicked around me- seemed like an electric or wiring problem to me which can be a fire hazard and what if I'm driving down the road at 70mph and all electric goes dead- steering and all. I have e-assist and second battery doesn't help when don't have power to transfer power. I have had car only for one year brand new.
