Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Speedometer jumped from approx.69 to 110 and continued to stay haywire and is not reading accurately. Apparently a known problem by chevy but they are only repairing in 7 years 70,000 miles. Of course I am at 4 years and at 77,000. I was over 74k miles when notice came out so even then would not have been able to get known defect fixed.”
NHTSA complaint #10250850, filed 2008-12, 77,198 miles“A short in the wiring that powers the heated seats and power drivers seat. Connector is burned and melted. As a result of the short, my battery has been drained twice. Luckily this was found before a fire or serious injury.”
NHTSA complaint #10244730, filed 2008-10, 52,341 miles“First occurrence was in 02/2008. Power seat adjuster and seat heater quit working. Problem found to be high resistance in the electrical connector under drivers seat. Substantial burning and melting of the connector present. Second occurrence on 2/13/09, found same high resistance problem at the connector between body and rear hatch. Caused rear wiper and defroster to become inoperative. Both incidents raise concerns about a vehicle fire due to the extreme heat that is produced by current flowing through a high resistance connection. …”
