Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Front brake line failed. Completely rusted, it blew out inside one the clips that hold it in place. Horrible design. Truck is sitting in my driveway because I cannot afford to repair brakes. Estimate was over 1500, just to replace the lines, with coated steel, not stainless. Fuel lines are all rusted as well. All need replacement.”
NHTSA complaint #10499973, filed 2013-02, 180,000 miles“Fuel gauge has been malfunctioning for several months now - sometimes works properly, but other times reads empty when tank is full, reads more fuel than in tank, etc. I have several friends who have this generation of GM full-size truck (Gmc Sierra, chevy silverado, Gmc yukon, chevy tahoe - gmt800 series), and most of them have the same problem. I am told that the issue is with the fuel sending unit.”
NHTSA complaint #10183294, filed 2007-02, 75,000 miles“When my issues started, I would fill my gas tank and the gas gauge would plummet to empty. While driving, it would go to full, back to empty or be anywhere in between. At that time, there no no mechanical issues, just the annoying fact that you had no idea how much fuel you actually had. This went on until this spring, when I had the first potentially dangerous incident. I was driving down a county highway at approximately the speed limit and the truck's engine just shut off. No power steering, nothing. It happened just as I was coming to a stop sign thankfully. …”
NHTSA complaint #10576461, filed 2014-04, 86,000 miles“State inspection, failed due to rotted fuel filler neck. Was told for awhile it was due to gas cap, replaced that, light would go on and off. When it would no longer go off took back to dealers. Dealership replaced fuel filler neck, along with valve/sensor at a cost of over $500. Gm will not help as they claim it was due to environmental factors (we live in ma). Also, parking brake backing plates rusted out, e-brake cables frozen, had to replace those at another $850. Old parts not available, dealer repaired.”
NHTSA complaint #10246093, filed 2008-10, 81,979 miles“Vehicle stopped running while driving 20 MPH, with a quarter of tank of fuel registered on the fuel gauge. Dealer was notified, and dealer informed consumerthat the vehicle was not covered under a recall.”
