“Driving on interstate 75 north of cincinnati oh in bumper to bumper traffic on 7-13-15 in left lane when buzzer sounded ,traction control light came on and engine lost power. Trying to get to shoulder was a bad experience as traffic was having one hell of a time trying to cope with a car that suddenly wasn't moving. How a bad accident didn't happen, I just say it was good luck! We really like our Buick Enclave and would like to keep it. I have a code reader and no code was revealed. …”
NHTSA complaint #10734635, filed 2015-07, 72,000 miles“A 18 wheelers tire tread was in the road. I straddled it to avoid a wreck. The tread punctured the front of my plastic gas tank resulting in a gas leak. I had to pay for a new tank and installation. There isn't a protective shield on the front of tank.”
NHTSA complaint #10423404, filed 2011-08, 35,000 miles“While driving, I noticed my engine started sputtering and had problems accelerating. Soon afterwards, the malfunction indicator light (aka check engine light) came on and stayed on. I contacted the dealer and took it in for repair. It was diagnosed as pistons misfiring . I had pistons/cylinders replaced at a cost of several hundred dollars. A couple of months later, the same thing happened and I had other pistons/cylinders replaced. This has happened about a half dozen times between march 2014 and today (march 2015). …”
NHTSA complaint #10702848, filed 2015-03, 100,000 miles“Was driving on ramp to enter highway, with my three 6 and younger children, and also 7 months pregnant! The Enclave just stalled and still can not start but one time it did, but it sounded like it was going to blow up making weird noises so I shut it off right away. I have been researching this and I see it is very common with 2009 & 2010 enclaves. I don't understand why nothing has been done? If this happened shortly later I would have been on the highway and several people could be involved getting hurt or killed. I have had it less than a year, with less than 104,000 miles on it. …”
NHTSA complaint #11130833, filed 2018-09, 103,926 miles“The engine on my 2009 Enclave was replaced in feb of 2012 because it was cracked , at the time I had approximately 32k on the car. There was no indication of a problem the car just died on a major highway. The car again died a few weeks later due to a timing belt snapping. On 8/10/12 I was traveling from my home state of new york to virginia for vacation, with my family, and the car lost power again on a major highway at 10:30 at night we had to have the car towed, find a hotel and then rent a car to get to our destination. This time it was a fuel injector and an o2 sensor. …”
