Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving with A/C set on auto the A/C system would suddenly turn off by itself and would turn of repeatedly when started again. During such episodes the A/C would act erratic with fans turning on and off at different outlets, cycles between heating and cooling, and makes hissing sounds. This would occur many times a day on a daily basis in summer weather (except when the car is taken to the dealer, it seems). It took about 2 years for the dealer to finally fix the problem since they could not avoid admitting its existence after I had video taped the malfunction and showed them the video..”
