Example complaints

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

“Speedometer is inaccurate and very sporadic. Speedometer needle gets stuck on any number when vehicle is completely stopped and/or turned off. Most of the time have to guess how fast or slow the vehicle is actually going. This is a safety hazard. After reading about the same type of complaints from other consumers, I think it's about time GM fixes this problem by initiating a formal recall. My grandparents swore by Buick and GM vehicles. I absolutely have my doubts now. If problem is never recalled, I will never purchase a Buick or any other GM vehicle in the future. …”

NHTSA complaint #10551220, filed 2013-11, 62,000 miles

“Instrument lights on radio, heat/air controls, steering wheel radio/cruise control controls started burning out one by one. Thinking that it would be a simple, cheap fix, I took it to the dealer. At that time, they informed me that they could no longer just fix the burned out bulbs, but had to replace the entire electrical module just to fix the light. What was once a $10-$20 fix has now become a $150-$200 fix per module. One module can contain one or two light bulbs, so if you have 6 or 8 burned out bulbs, it can cost you up to $1600 to fix! …”

“Started out as a headlamp that we thought was burned out. Replaced the bulb and it worked for a day or two. Next the gas gauge, speedometer, heat and cooling gauge and now both headlamps do not work. My husband has to drive in the dark with brights on because there are absolutely no headlights . This is a serious safety issue and GM should be issuing a recall. This is extremely dangerous and we cannot drive our vehicle at night unless we use our brights the whole time which then becomes a safety issue to other drivers. This is as serious as seat belts failing or windshield wipers out of whack. …”

NHTSA complaint #10587636, filed 2014-05, 100,000 miles

“Originally when the issue happened at random times with the speedometer readingin inaccurately. Now it has fallen to the 6 o'clock position and never moves from that position. I have never had it repaired was told by dealers that the part was the instrument cluster and it would need to be replaced. Issue started at around 86000 miles (random readings) around 91000 speedometer (fallen to 6 o' clock position.”

NHTSA complaint #10575512, filed 2014-03, 86,000 miles

“Vehicle speedometer works on and off. Speedometer reads 20 MPH when going 60 on hwy. Took vehicle to dealer and they stated that the entire instrument panel would have to be replaced at a cost of 800 plus labor..... Vehicle has about 60,000 miles and had 55,000 at time.”
