Check Engine Light On problems of the 2013 Buick Enclave

After any amount of rain, the vehicle will not shut off after turning the key to the "off" position and removing the keys. The vehicles dash lights all go off with the exception of the "check engine light". The vehicle remains running. I have to pull a fuse to get it to shut off. Then, the next morning I have to jump it to get it to start.

While driving my 2013 Buick Enclave traction control, service stabili track flashes across dasboard. The check engine light comes on and engine speed is drastically reduced. Car does not accelerate properly and rpms are not producing speed. Car is lethargic and signs begin without warning. Once engine is turned off and turned back on traction control rests and display messages disappear but check engine light remains on. Temperature or weather or type of road you are driving on does not play a factor in defect of traction control stabili track.

My 2013 Buick Enclave started having problems back in December. When I was driving all of the sudden the car chimed about 3 times then all the sudden the dashboard read the following: 1. Engine power is reduced 2. Service traction control off 3. Service stabilitrak 4. The engine light comes on at the same time, the engine power started to die down and I was barely moving. It was hard to steer and all power functions greatly reduced. Once I shut it off and restarted the car my check engine light stayed on but it switched from traction control off to traction control on. Then I was able to continue driving again. I bought this vehicle thinking it was a good family car but now after dealing with this problem and seeing all the complaints online and nothing being done, no recall, I made a bad choice. My children were with me when this happend a few times and we were almost rear ended because of it. The car literally stops working. This is a very dangerous problem and is not uncommon to GMC vehicles. I do not feel safe driving this car. I don't understand why GMC has not identified the problem. I am taking it to nimnicht dealership tomorrow in jacksonville. Hopefully they have some real answers before this car ends up killing me or someone else. Very disappointed GMC after reading all the complaints and nothing being done.
