2011 Buick Enclave: check engine light

Filed Oct 12, 2026 · Engine, Lights · IL

The check engine light has been on for over 2 years now. It turns off and on, so it makes it hard to pass the emission test. I have replaced what shows on the emission testvas failed which are both catalyc converters, oxygen sensors and I also had to replace the engine in 2018. I have spent over $10k on the car and it still has the same codes appearing. I take it to different mechanics and they tell me they don't find anything because what the emission report states is not a problem on the vehicle. They don't understand why the light is on and they all tell me this is a huge problem with Buick Enclaves. Just get rid of it and never buy another one.

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 $125.00 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 $125.00. 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.

We purchased a 2011 buick enclave for what we thought was a great deal. We were prepared to pay for basic maintenance right after purchase. The check engine light came on as we were driving on the highway. I noticed loss of power while on cruise control(set at 65mph) and the vehicle started shaking. I noticed the RPM jumping from 1 to 2 . We took the vehicle to buick for repairs. We had a tune up, 2 catalytic converters replaced, 3 o2 sensors replaced along with one other one that I'm not sure the name, oil change, struts and shocks, rear sway bar links, air filter, and a gasket manifold. We have not had this vehicle longer than 2 months. The vehicle is still doing the same thing. Today after we picked it up from the shop(no check engine light) we drove it on the highway and now the service traction control light is on along with stabilitrak control. We have 6 children. This is dangerous. What are we to do?

Check engine light came on and vehicle suddenly reduced speed while driving on residential street. Message displayed on panel, "engine speed is reduced." in a separate issue, we were advised by the dealership to keep driving the vehicle even if the check engine light appears to empty out the fuel. The dealership believes the fuel is bad. This may be related to the first issue, but I am unsure.
