Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“1) fuel gauge - the fuel gauge has done a 180, the needle is now upside down. And doesn't work really. I searched the internet and found out the there is a recall on 2005- 2007 Buick rainiers but not on my 2004. Maybe with my complaint, maybe it will include 2004 models. 2) drives door lock - the car key will no longer open the car door. I can only open the door with the remote button.”

NHTSA complaint #10467527, filed 2012-07, 79,000 miles

“My 2004 Buick Rainier has a gas leak. I'm told that the plastic tank is the same one used with the gmc envoy, the gmc trailblazer, old bravadier and perhaps others. The filler pipe welding breaks near the plastic tank and gas escapes. This is known problem and has been reported by many other gmc owners. This could be a the cause of fatal fires but gmc would rather ignore this safety problem.”

“Fuel tank is leaking at the filler inlet. This same problem was covered under a recall on chevy trailblazer ext's which share many of the same components. There is a smell of fuel in my garage and it is clearly visible on my garage floor. Why wouldn't GM cover all vehicles of the same build and not just the trailblazer? I am afraid my car will catch fire overnight or while my wife and toddler are inside it.”

“I have had this vehicle for 4 years and the speedometer has not worked for 2.5 years now. It will work if I reset the battery or turn the key over until the needle goes back to 0. I am told the instrument cluster is bad and I see that there are other complaints also. Please help. I need to know if this is covered at a GM dealership for free. The vehicle also sputters and I have already replaced the fuel pump and had the injectors looked at. If you can please email me or contact me I would greatly appreciate it.”

“I noticed in november of 2016 my Buick rainner was smelling like gasoline after I got out and left it running while I was dropping stuff at home from work. When I got back in my vehicle I didn't smell anything, but could smell outside the vehicle. I went about another 10 miles later to my destination and park. 20 mins later went back out and crank my vehicle and could smell a strong gas odor coming thru vents on the inside of my SUV. I got out and looked under my hood and didn't see anything wrong under the hood. When I walked toward the back of the vehicle the gas smell was even stronger. …”
