While driving at 60 mph around a curve with an incoming semi, the car suddenly lost power and the steering locked up. By the grace of God, we were able to avoid the semi and get it off the road. Had it towed to mechanic who said the engine was blown. Regular maintenance always kept. Just had oil changed two weeks ago. This could have been deadly!!!

On February 27, 2023 while on the road in the morning heading to work I stopped at a red light. When the light turned green my 2011 Buick GMC Enclave hesitated when I proceeded to accelerate. My vehicle moved slightly then without notice it stopped in the middle of a busy road as several cars backed up behind me as my check engine light came on. Also, while my foot was on the brakes, my vehicle was rolling backwards. In lieu to this hazard to myself and other drivers I placed my vehicle in park. My vehicle was towed at my own out of pocket expense of $125 in addition to $16.99 for a Lyft ride home. Two days later the auto shop informed me they checked my battery and alternator and both was good. They continued to tell me they drove my vehicle and it did not cut off or stop running. I informed them I DON-€™T FEEL SAFE KNOWING MY VEHICLE SHUT OFF WITHOUT NOTICE could they check it again. They kept my vehicle another day and they stated NO CODES SHOWED UP AGAIN THAT THEY CAN POINT TO A SPECIFIC ISSUE. Again, another out of pocket diagnostic expense of $125. On 02/28/23 I contacted AutoNation Buick GMC Laurel to inquire if there has been a RECALL in place. The representative stated there WAS NO RECALL IN PLACE. After extensive research and review to my ultimate shocking surprise I see numerous complaints have been expressed with Buick GMC from consumers and previous customers outlining their concerns and this hazardous life threatening situation of THEIR BUICK STOPPING WITHOUT NOTICE. Buick GMC is aware of this repeated life threatening and dangerous issue from consumers and from previous customers year after year after year. Buick GMC nevertheless STILL REMAINS SILENT AND HAVE TAKEN NO ACTIONS NO REMEDY NO RECOURSE ABOUT AMENDING AND CORRECTING THE DANGERS OF THEIR MANUFACTURED VEHICLES. SUBSEQUENTLY, BUICK GMC HAVE NOT TAKEN THE NECESSARY STEPS TO IMPLEMENT A RECALL.

The check engine light comes on and off. The dealer pulled code P0008. Engine position system performance bank. There is a bulletin out for this code, indicating the crankshaft moves and gets out of time. They said the only fix is to replace the crankshaft. The dealer advised replacing the engine, since the cost is about the same, $9,864.21. I have kept up the maintenance on the vehicle, and it has only 132,820 miles.

I purchased the vehicle on 11/4/19. The dealership, salesman or service department. Didn't inform me or put it in writing that the crankshaft sensor was faulty on the vehicle. John Eagle Acura didn't consider safety first. On 11/7/19 at 48,076 miles the vehicle won't crank. It was cold and rainy so I didn't drive the vehicle. On 11/17/19 I drove the vehicle to church at 48,124 miles. When I got out of church it won't crank. I called the dealership on 11/18/19 and told them about the vehicle. They told me to bring it in. I brought it in on 11/19/19 at 3P.M. I asked the service department what was the problem because the vehicle won't crank. They told me that it is the crankshaft sensor. I told the salesman that you knew it was the crankshaft sensor and you put my safety at risk. Because you and the service department and dealership knew that the crankshaft sensor was faulty and my safety was at risk. He said to me and my husband that he knew and said that he should have given me a loaner car. But he never told me about it.

My regularly serviced 2011 Buick Enclave with approximately 75,000 miles on it began overheating last summer to the point when turning off the engine the radiator fan kept running. My servicing business was continually adding the recommended radiator coolant in amounts that totaled 3.7 gal. Between mid June, '18 to Sept '19. I was told by the dealer the radiator holds 14.2 qts of coolant which is 3.5 gal. So it lost over its total capacity. It did the same overheating with the radiator fan running after the vehicle was turned off this past summer. There is a recall 13091 on this issue of a leaky water pump for 2008-2010 Buick Enclaves as well as similar years for traverses, acadias, and outlook on hfv6 engines (LY7, llt) I was told that GM did not change the faulty water pump until 2013 on the Buick Enclaves. The car showed no error message of overheating or low coolant on the display panel. This is a safety issue. If the water pumps goes out while driving it could cause the engine to blow with a possible engine fire, unsafe for driver and passengers.

Hello - I am writing as a concerned consumer. I currently own a 2011 Buick Enclave. Two weeks ago, while driving this vehicle it started making a very loud knocking noise. The car then completely shut off and became inoperable while driving down a hill. With loss of power steering and the inability to restart the engine it became a dangerous situation trying to get the vehicle stopped and safely off the road. The vehicle was taken to a garage and it was determined that the issue was a broken timing chain. This repair required the removal of the engine to replace the timing chain. Research into Buick has shown that there is a bulletin out for this very issue but only for the 2009 model year. My 2011 was manufactured in 2010. For this very issue, Buick has extended the manufactures warranty to 120K or 7yrs. Research shows that this timing chain issue is not exclusive to the 2009 as owners of other model years are expressing the same concerns. I am writing to file a formal complaint, as this is a safety issue that Buick refuses to acknowledge. The failure of this timing chain lead to a situation that could have caused a wreck and possible injury. I have contacted Buick several times and they refuse to provide financial compensation for the repairs and refuse to investigate this further. Their response is simply, there is no bulletin so there is nothing that can be done for me.
