Bought a 2009 Buick Enclave from CarMax on 11/18/2017. Had to replace the timing chain on 7/20/2020.

The timing needs to be replaced and am trying to find a Buick dealer that is reasonable. I am sure most are experienced as this is a known problem that GM will not stand behind. So far I have been quoted $3711.31 and $4818.00 by 2 different dealers; a third one wanted $95.00 to give me a quote and I would have to leave the car over night and they would not provide a loaner.

The car has never been serviced by anyone but a Buick dealer and at the prescribed service intervals.

I bought a 2009 Buick Enclave last year and the timing chain went out this year.

09 buick enclave cxl 3.6 126,000 miles. The check engine light is on. It's throwing codes like 13 different codes. It's misfiring. Like it's going to die on me. I put on new spark plugs, catalytic converter 3, o2 sensor x4 and coils and it still do the same thing. It's the timing chain.

Very pissed I bought this vehicle in the first place , the day I drive it off the lot timing chains , that was covered under warranty less than 1 year later , valve spring broke the head was rebuilt , this truck is in the ship more than on the road . It stop running last week on the way to my sons track meet 30 mins away the shop just called no compression in cylinder 4 GM should be ashamed of this vehicle !
