Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Driving on interstate at 65 MPH, the ABS warning light came on, and the speedometer started jumping erratically from actual speed to lower speeds 45, 25 + others as low as 8 (eight) MPH. This caused the transmission to downshift unpredictably, over-revving the engine speed. It happened repeatedly so I documented the odometer erratic movement on my cell phone as a video, showing road movement + all gauges + audio events like engine over-revving at same time. The video is of high quality and the events taking place are documented with the video. Rural area with few cars on road at the time. …”
NHTSA complaint #10629518, filed 2014-08, 16,614 miles“Dt: contact owns 2003 Chevrolet Express g3500 passenger van. The van will accelerate on its own sporadically. This started around 7-20-05. It does it while stopping at stop light and it will also do it while driving on the highway. The idle speed control motor, throttle position sensor, cooling sensor, ECM, and the prom have all been changed within 5-6 weeks. He says it did it at any speed sporadically. He made an appointment to bring the car in again for a possible repair. The check engine light will usually come on after an incident.”
