“The timing change is leaking it was fixed back in 2019 it hasn't even been a year now since I had it and it's leaking again I was driving home when I noticed a smell like oil burning and when I park the vehicle it started leaking from the front of the vehicle where the timeing change is housed”
NHTSA complaint #11337991, filed 2020-07, 119,280 miles“My 2009 Buick Enclave had to have the timing chains and also 1/4 actulators replaced at just under 78,000 miles. I did go ahead and have the other 3 actulators replaced since they already had to drop the engine out of my car to replace the timing chains. This was a huge expense and after doing some research online it seems that a lot of GM motors from 08/09 have had the same problem.”

None of these items were listed. …”

The fire started from the right front of the vehicle, which results in the whole car totaled. Me and my family have been suffering much from this event.

On 5/31 we reported to GM with detailed information and requested an investigation. …”
