NHTSA Complaint #11444431 — 2013 BUICK LACROSSE

The climate control systems have stopped working. The temperature is locked to the last set temperature and blower zone (blowing lightly on feet only). It is available for inspection upon request. This is a significant safety issue as the climate control panel will not power on, affecting defrost for all windows. This is especially dangerous in Michigan during the winter months due to the need for defrost during spontaneous/lake effect snow. No defrost can cause significant visibility issues, which put the safety of the driver, passengers and others at risk. This malfunction also creates a safety issue because the vehicle is unable to be heated up properly when temperatures drop. This problem has not been reproduced or confirmed by an independent service center, nor has it been inspected by anyone. There were no warning lamps. My son (Ralph) has been helping me with this issue.
