I noticed today as I was stopped at a red light with my foot on brake the vehicle was kinda jumping like it was trying to go while foot was on brake. I drove a little further and the service stabilitrak light came on followed by the reduced engine power. The car proceeded to die in the middle of a busy street. After a few minutes it did restart and I was able to get it home. This seems to be a common problem with 2011 buick lacrosse. Ihave seen several complaints about this same issue.

Our family's 2011 Buick Lacrosse only has 57K miles on it, and the engine already has permanent irreversible damage from a manufacturer oversight in which the timing chain "skips time." While driving on the highway, the car unpredictably lost all power, including power brakes and power steering. I quickly muscled the car to the shoulder and came to a complete stop, but this created a very dangerous situation for our family as we were forced to cross traffic, at speed, to reach the road shoulder. A day prior to this incident the vehicle went into "reduced power" mode while traveling uphill, cutting speed from 55mph to 35mph, backing up traffic. Cars were passing and honking in a double yellow-lined stretch of road. We subsequently shouldered the car, shut off its power and it seemed to be operating properly until our destination, but we only had 3 miles left to travel. The timing gear is pressed-on instead of keyed-on. This can cause the timing chain to "skip time, " damaging the engine and causing erratic engine behavior. Our mechanic has seen our exact engine issue with the 3.6L 6-cyl engines in various other GM vehicles. The problem is widespread enough to cause engine rebuild companies to key-on the timing gear, instead of GM's typical press-on process. Our mechanic advises that keying-on the timing gear is known to fix the original issue of the timing chain dangerously "skipping time." One such company, recommended by our mechanic, is jasperengines.com. I hope that the NHTSA can investigate this issue and hold GM accountable for this dangerous oversight for which GM fails to acknowledge or address. My complaint is on record at GM's Corp service center with phone number 866-790-5600 - ticket #[xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My car stated that my trakstabilty system needed to be serviced then reduced engine power lite up. Car would not shift and would not increase in speed over twenty miles per hour. I had to pull over and turn my car off leave it parked until I could get it to the dealership. The throttle body was defective. This has happened on other 2011 Lacrosses and their is a special service bulletin with free repair but for some reason not in mine. I had to pay 500 dollar to replace this. My car only has 74000 miles on it and I could have been injured if I wasn't in a place where I could turn my vehicle off safely.

Excessive oil consumption, piston and piston rings. Burning 3-4 quarts of oil every 2000 or less miles. After checking I find out this is not covered under warranty because it was not make at a specific plant. I have approximately 95,550 miles. I thought Buick were good cars and stood behind their product. This is quiet expensive, can you help? the oil light doesn't even come on when it got that low. It started acting funny and when checked, low oil, no. I have kept my vehicle very well maintained. The first time it happened around 10/16/17 and after looked at again 1/8/18 drips or leaks
