July 23, 2019 -I was on the hwy for approx. Four hours with my niece when suddenly my car created a loud sound and I lost power and control of my car including my brakes. I was traveling at 70 mile per hour. Luckily, two cars had just passed me when this occurred otherwise I could have had a very serious accident. I was on the left lane and was able to coast to the shoulder. The hwy. Was flat and I was able to coast to a stop. The engine wouldn't start, but after approx. Five minutes it started but I wasn't able to move. The car idled extremely rough. The electronic stability control (ESC) light and the check engine lights were on. I waited for a tow truck in 96 degree weather for two hours before I was able to get a tow to a garage 40 miles away. This happend on tuesday. I left my car at the buick dealer and left the key in the drop box. I was told wednesday morning that they wouldn't be able to look at it until today (thursday), so I have no idea as yet what damage has occurred to the engine. I have only 53,000 miles on the vehicle and it is a 2011 model. How could something like this happen?

Driving 60 MPH on the highway. Suddenly the information panel flashed stabilitrak service required (or similar) then low power mode. Car went from 60 to 30 MPH on the highway. Unable to speed up. Needed to pull over to the side of the road. Turned car off. Tried to restart and it wouldn't restart for several tries. Restarted and still said low power and was idling low. Tried again and was normal. This has happened several more times and always is similar. Sometimes it doesn't happen at all in a 30 mile trip, sometimes it happens 3 times. Very dangerous! Could be rear ended! I have read many other accounts of this happening in the 2011 buick lacrosse. After this the check engine light stayed on. When I had the auto parts store run diagnostics it flagged multiple misfires, throttle position sensor 3 times, power control module indicator, traction control. It seems this is a flaw in this car. I attempted to get a picture of the satbilitrak sensor indicator light, but it flashes on and off pretty quickly and you never know when it will happen.

Electronic climate control system allows windshield to become fogged over and I cannot see to drive or control HVAC system. I cannot control the heating, cooling and ventilation. Example: the system seems to blow or allow warm air in cabin when the A/C is on set at 68-72 degrees. This is when car is in motion and at idle on any road I travel.

Twice after filling up with gas, my car was oils not start at the pump. Each time I had to wait several minutes before it would actually start. The second time it happened, I waited, it started then immediately quit again. There is a very hard start when it attempts to start as well. The engine light came on then immediately went off. I took the car directly to the dealership where it had to remain running until they could get it in. This was 540p on friday, may 25th before a holiday.

The transmission,with approx 89,000 miles burned up while I was on a road trip. I was 9 hours from my home and alone with a full car of vacation equipment. I was on interstate 24 in nashville tennessee. I pulled off and a service station checked why the engine light was on. They said the codes showed transmission problems. I should try to get to the nearest buick dealer, in clarksville tennessee. They said it would make it. I was alone. Thank goodness for onstar. I had to spend the night in clarksville because the dealership was closed and it was getting dark. The car was barely moving by now. It was frightening. I stayed the night at a baymont in clarksville and was at the dealership at 6 30 am. Was praying it could be fixed and I could continue on my was to milwaukee with my beautiful car, which I had put so much effort in keeping in good running condition. Just before my trip, I had replaced my tires with beautiful michelins, and sick my car had gone into limp mode twice, replaced the throttle body. Everything ready for a road trip to amelia island from milwaukee. Wyatt johnson dealership said the transmission was shot. 4500.00 to fix, and would take a week. I was stuck. I had to get home 9 hours away. I would need a rental to drive home, then drive back then drive home if I would have the new transmission. I gave my beautiful car to them for 1500.00. I bought another 2015 lacrosse. I had to unload a full car into the new one. Extremely frightening situation. I now have a 2015 buick lacrosse which I bought for 19,800. Just so shocking that an american made transmission would burn up at 89,000 miles. The car was in motion, but in slow traffic on the expressway in nashville when the problem began. I will send copies of all documents.

2011 buick lacrosse (60,000 miles - properly maintained by 73 year old man) broke down on interstate hwy. While vacationing in knoxville, tn - buick begins to stall and the engine light came on (was flickering and no acceleration). We stopped immediately at a gas station and called aaa - who towed us to a certified aaa repair/tow company. We initially suspected it would be the fuel pump or filter . Mechanic in knoxville who is a ase certified mechanic for 40 years said it wasn't the fuel pump so he put his diagnostic tester and determined there were more problems and started to take apart the engine....and found the main valves were broken and fell into the pistons. Engine failure and he said in his 40 years this had happened only 3 times but not on a 2011 car with only 60,000 miles. He said if we would have continued driving, the whole engine would have blown up. Called the local buick dealership and found out no recall, nor did we have the extended warranty (a big mistake - and we loved the lacrosse thinking it would last a long time). Looked up blue book value - worth $11,000 (with running engine) and a new engine would be approx. $8,000 and would take a week to replace. Sold the car to the mechanic in knoxville, tn) and purchased a new toyota avalon in knoxville. Very very disappointed in g.m.
