“My 2012 Toyota Corolla has issues with the electric locks. When I try unlocking my vehicle using the keypad or the electric locks within the vehicle, it simply does not work on my two front doors despite having electric locks in my vehicle. My research of other customers' issues online reveal similar issues to mine. …”

NHTSA complaint #11330018, filed 2020-06, 70,000 miles“I have experienced this since the beginning of the purchase. I use the air condition. If I am done, I turn the AC off. After using the AC, there is a foul odor that arises. I have tried to open up the vents. I have checked underneath the car. I have opened the front where it leads to the cabin filter. I have changed the cabin filter several times. The odor still persists. The only thing that the car dealers have told me to do was to run the heater after using the AC. It is redundant if I have to run the heater in a hot day.”
