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.

The power liftgate door opens 75% of the way when I push button or manually but then starts to closes again. I have been hit by the door several times already due to door closing. Also day light on passenger front goes on and off. It will work for a few days then not work for weeks. Have had light bulb replaced and continues to happen. *Tr
Day time running lights. Left and right side lights go out for no apparent reason. Had two side replace the the other side not under warranty. Lights come on for several days, then will go out for no apparent reason sometimes while running sometimes not. Has happend on and off since 2014.
Tl* the contact owns a 2011 buick enclave. The contact stated that at any given moment or speed, the daytime running lamps dimmed. The contact was not doing anything to trigger the failure. The vehicle was repaired, but the failure recurred on several occasions. The manufacturer was notified of the failure. The vin was unknown. The failure mileage was approximately 90,000.
Hid lights turn off after our 2011 buick enclave is driven after 30 seconds. Headlights come on when vehicle is first started at 4:30 a.M. And turns off as indicated above. Issue has been addressed by the buick dealership but cannot determine the cause of the issue on three visits. There are no recalls from the manufacturer, as stated by the service advisor. Manipulating the controls is the only workaround. [[redacted]] information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6). *Tr
