“I started my car and went to take off and the air bag light came on. There was a couple of incidences where I had a passenger and the airbag light came on to service airbag. I've read in multiple places where this occurrence has happened and the manufacture should fix this.”

“I was trying to start my car and turned the key in the ignition and my car was completely dead. I thought it was the battery and tried to take the key out, but it was stuck and wouldn't come out. I googled how to take it out and that worked, we jumped the car thinking it was the battery, but without the key in the ignition, the lights and electrical allturned on. This tells me that the car's ignitor/shifter was stuck in the on position. It could have been a dangerous situation if I were anywhere but home.”

“Connector feeding power to the A/C-heater blower melted; caused a crackling sound, a smell, and the fan to stop working. The connector melted together. To get a picture of the pin that failed required me to break the connector. Power was present on the brown wire as soon as the ignition is on - the blower did not need to be operating to generate heat at the connector. The wire leading to the connector was discolored from the heat.”

Door locks were still going up and down several hours later at the vehicle impound yard and was observed by the police officer and noted in his report. Additional. This problem is much bigger than believed! …”
