Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on the highway and looked down and the speedometer said 100! Cars were passing me and I knew there was no way I was driving 100. Once I got to my destination, sitting still the speedometer was at either 50 or 60. When in motion it usually reads about 105-115 when going between 60-70 MPH. (I think, I really have no idea since my speedometer is broken!!!) I have just over 75,000 miles on a 2005 SUBURBAN 1500.”
NHTSA complaint #10257051, filed 2009-01, 75,600 miles“My 2005 k1500 suburban sustained a cracked head with 73,000 on the engine. The service department at my dealership has no information that a manufacturing problem exists. The repair cost over $2,000. This is not a normal occurrence or expected vehicle wear.”
NHTSA complaint #10252833, filed 2008-12, 73,000 miles“The contact stated while driving 50 MPH on a dry highway in a passing situation, a light stating reduced engine power illuminated in the vehicle. The vehicle lost a majority of the engine power, and the tachometer would not pass 1200 rpms. The vehicle was not immediately taken in for service.”
