NHTSA complaint #11210741, filed 2019-05, 152,000 miles“I purchased a 2008 Suburban ltz in july 2011. Shortly after we purchased the vehicle 3 of the doors locks have stopped functioning completely, the 4th door works sporadically (driver side, passenger). The locks do not work at all with the keyless entry nor the main lock button from the driver side door. I have been told that it is a problem with the lock actuators malfunctioning and that it is also a well known issue from various dealers and per my research on the internet. …”
NHTSA complaint #10524919, filed 2013-07, 50,000 miles“My 2008 chevy Suburban with 94,000 miles stalled while in traffic traveling at about 20 MPH without warning. I luckily was able to coast it to the side of the road and after letting it sit for a short time it did restart again but only to stall again after the car ran for another 5 minutes again traveling at about 20 MPH. I had it towed to my dealership and have been told that my crankshaft position sensor has failed. While my VIN and year is not covered, there is an active recall on this condition (GM recall no. 06083.). …”
NHTSA complaint #10683694, filed 2015-02, 94,000 miles“In 2008 it was hard finding a Suburban as a lot of dealerships closed already. So I found a dealership in glendale california. It was far from where I lived. When I was opening the sunroof it started going back and forth. I couldn't believe it. Ii had a long trip home and I was hoping that it would just resolve itself but it never did. I have told Chevrolet many times about this problem and you will find my records of how many times I had called them to resolve my problem but they never ever did a thing about it and it is still happening to this day. …”
NHTSA complaint #10881838, filed 2016-06, 45,000 miles“After driving for approximately 3 hours the problem began: the door locks cycle repeatedly, the instrument console flashes, the drive position flashes from park to drive repeatedly, the radio stops working, the vehicle surges, and the stabilitrac says it needs to be serviced. This is the second report we have filed in a month. We have already taken it to the dealership once for this problem in early august when it was just the radio malfunctioning. They said to replace the radio. …”
