GMC Canyon intermittent window and mirror warning light issues with non-functional remote start in cold weather on GMC Canyon

Some GMC Canyon owners report experiencing intermittent window issues, where the windows may not operate as expected, even in newer models with low mileage. This problem may be linked to a defect in the logic board of the driver's door switch module, prompting some owners to seek workarounds due to the high replacement costs. Additionally, some owners have noted that the heated side view mirrors, designed to prevent fog and frost buildup, may not function properly, compromising visibility; checking the mirror heater switch inside the vehicle is recommended. In cold weather, some GMC Canyon owners find that the remote start feature may not work as intended, with the engine potentially shutting off if coolant temperatures rise too high or oil pressure drops too low. Furthermore, common complaints regarding the GMC Canyon include transmission problems, particularly a noticeable shudder from the 8-speed transmission in second-generation models from 2017 to 2019. For persistent issues, consulting a professional mechanic or GMC dealership is advisable.
