When accelerating engine will shudder, lose power and drive very bumpy. I have taken vehicle for service. We have replaced all filters, points and plugs. Given the vehicle a tune up and the problem has not ceased. The check engine light is not illuminated so the computer does not give the repair shop the information it needs to repair whatever may be occurring with the engine.

My vehicle just turned off while at a stop sign preparing to turn. It was towed to a mechanic that advised it was 2 quarts low in oil (oil was replaced 2 weeks prior) and that my battery needed to be replaced. They added the oil and replaced the battery. I drive the car ~ 5 miles home and it stopped again. This time when trying to start the car, there was an audible screeching coming from the engine and the engine was shaking. The mechanic offered to towels the car back to their shop. After inspection, they advised that "something" was broken inside the engine and that it needed to be replaced. My car has 75,000 miles on it; has had regular maintenance; there were no check engine lights and/or over heating lights. I was also advised by the mechanic that this is a common known issue with buick. I'm now left with having to pay anywhere from $7500-$8500 to replace an engine on a vehicle that I've had for 2 years.

My 2012 buick enclave started having problems on feb. 14th. I was driving my daughter to school and all of the sudden the car chimed about 3 times (almost like the seatbelt sound) ' then all the sudden the dashboard read the following: 1.engine power is reduced 2.service traction control 3.service stabilitrak 4.the engine light comes on at the same time, the engine power is so low that I had to literally floor it, it wasn't even going 5 miles an hour, it was hard to steer and the brakes were hard to operate --- all power functions greatly reduced. Then the engine idles hard. This video is exactly what my car does: [xxx] there is no rhyme or reason when this happens---- very random. After a few minutes, I was able to restart the car and drive it to the dealership (the engine light was still on). Since the dealership can't duplicate the problem, they were unable to determine the cause for the problem. Since then, this has happened 10+ times. Recently I was going about 75 miles an hour, on the interstate, the car chimed, all the same things on the dash board, I went from 75 to 20 in seconds. Yesterday (6/11/18) was the last straw. I was going 45/50 on a major roadway when my car stopped working again. There was no shoulder to get to - an 18-wheeler carrying a large tractor had to swing into the next lane to avoid hitting me. It is only by god's grace that no one was hurt yesterday. Once the chime sounds, the car literally stops working. This is a very dangerous problem and in looking on the internet it is not uncommon to gmc vehicles. I have children and do not feel safe driving this car. I don't understand why gmc has not identified the problem. I found this video on-line that seems to identify the problem.
