Engine
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.

I contacted OnStar and they pulled many codes P02AD,P0300 x2, P0305 x 2 at 126,362 miles with 73% oil life remaining. I contacted by Mechanic and was able to have it towed to his show for him to inspect it and the engine was totally seized. While I did research before purchasing this car the year before (I only average about 6k miles a year) I missed that this year and several others have a known issue that the engines can grenade themselves. I called my insurance company as I had full coverage and gap…

I have had my car looked at and my camshaft reductor wheel/valve is broken. This happened very unexpectedly and almost caused a serious accident at highway speeds. I was able to drift the car to the shoulder from the middle lane, but almost was hit by a semi when my car randomly stalled out in the middle of I-5. This is a problem I have sense researched and has happened to many others with the same car and model year.
