Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My speedometer quickly jumps from one indicated speed to another speed that is clearly inaccurate, down as low as -0- while driving, accompanied by the transmission attempting to downshift on it's own, which causes a severe engine over-rev condition or going into a neutral momentarily with no input from me as the driver. There are no specific actions I can take to trigger the erratic symptom, nor any specific action I can take to cause normal operation. …”
NHTSA complaint #10667542, filed 2014-12, 15,500 miles“My 2003 chevy Express 2500 cargo van was in evening rush hour stop and go traffic. After reducing my speed to 10 MPH then attempting to accelerate. The vehicle stalled and began to idle rough and shut-off. I had to put the vehicle in neutral and restart in the middle of the interstate. I had to continue to shift into neutral and press the gas to prevent the vehicle from shutting off in the middle of traffic. I had the plugs and wires change the very next day and the problem continued. This could have turned into a major accident with the vehicle shutting off in the middle of traffic. …”

NHTSA complaint #10583405, filed 2014-04, 254,000 miles“This vehicle was bought brand new but unbeknownst to me was made in canada (something which would not have been acceptable to me had I been told). Upon possession the windshield molding came off on the ride home. The driver side tierod end went at 12,000 miles and again at 24,000 miles because upon inspection the ball joints were never properly tightened. The bolts on the transmission were found by the dealer to have been never properly tightened. The sidedoor hinge had to be replaced at a cost of $600 because it froze up and could not be opened. …”
