Gear shifter is not registering that the vehicle is in park. Because of this issue I have to sit in the vehicle for up to 15 mins trying to get it to register that it is in fact in park and can turn off. If I didn't take the time to do this, it would kill my battery. Unfortunately with the heat index, the vehicle gets hot very quickly and im now worried about getting hot stroke trying to get it to register it is park. This is a known issue with the vehicle that has an active recall for other vin numbers with the same issue.
Hesitants and Shudders when shifting into 2nd gear.
the transmission kept slipping. the car continued to lose power until it just wouldn't go anymore. The mechanic said it is definitely the transmission and drive shaft but my particular VIN is not included. I am looking at $7,000 in repairs on a car I owe $13,000.00
