Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car had around 65,000 miles on it, and all the sudden the heat stopped working. Air would blow, but it would be cold air. We replaced the thermostat, as a mechanic told me to try that, and see if it helped, but the heat was still not coming out. Eventually, as it was getting really cold, we took it to the mechanic, and it cost $498.30 to fix! He said the water shut valve needed to be replaced.”
NHTSA complaint #10255359, filed 2009-01, 65,500 miles“Clicks for 10-20 seconds when I switch from AC to heater and back every time. Twice while driving I switched from AC to heater and heard no clicking, but also got no heat (still blowing cold air). Started happening after about 5,0000, and has been ongoing for a few months.”
