Five problems related to equipment have been reported for the 2009 Chevrolet Suburban. The most recently reported issues are listed below.
Powered lift gate opens on its own with out pushing the button on remote or button on dash.
On three (3) separate occasions in the past year, the vehicle enters what appears to be an "electrical system reset" of sorts. This has occurred on long distance trips during operation at highway speeds. The entire electrical system will suddenly power off and on repeatedly, the electric door locks will unlock and relock, the engine will lose power (quite scary at highway speeds) and the vehicle must be removed from the road, powered down, let sit idle for 5-10 minutes and then can be restarted to a normal operating condition. It is almost as if the computer system is resetting itself while the vehicle is in operation and moving. This has happened three (3) times in the past year - all on long trips - March, July, and November. The most recent, instance occurred about three hours into a return trip home and recurred again about 1-1/2 hours later (10 minutes from home) during the same trip. By restarting/resetting the vehicle, I was able to get home. I took to advanced auto and the diagnostic came up negative - no codes, battery and startup all good. I have a large family and use this vehicle to transport them around town and for vacations and such. This is quite a dangerous situation when it occurs and I am afraid it may leave us stranded at some point in time, or worse.
The driver side temperature control is very distracting while driving. The setting stays at maximum heat / hot and does not change with the ac running. The driver is always extremely uncomfortable and distracted by trying everything to over and over. Keeping the upper vents closed still hot air comes through. You must keep the system completely off the floor vent, the driver side is extremely hot and causes distraction. Is this a new or unknown report for this vehicle? what has failed to create this problem? is this a safety problem, only while driver is in the vehicle and driving for more than 15 minutes and even worse during summer season.
Takata recall in addition the dash has split leading right up to the inflator cover. Vehicle was stationary when split appeared. Got in the car (parked in garage) one morning and split was noticed leading right up to the inflator over.
Door locks no longer working on driver door, front passenger, and now rear passenger. Dealership says all three need replaced. Driver door went first, then front passenger, and then rear passenger. I have found several postings related to multiple door lock failures - not just single locks, but many cases of 2-4 locks failing on a single vehicle. Locks are very expensive to replace (especially in quantities of 3 or 4) and represent a safety issue if the doors cannot be secured.
