Takata recall, have contacted dealer to remedy safety issue and understand there is no current solution or anything being done about a major recall to the supplement restraint systems fitted in my vehicle. Manufacturer has no future date for safety concern being resolved. I feel unsafe driving this vehicle. Transmission failure at high mileage due to torque converter seal failure and voltage spike to solenoid 3 causing transmission temperatures to rise and result in premature failure of zf 6hp19a transmission. Have contacted manufacturer and zahnradfabrik friedrichshafen ag to report premature failure of transmission, have not heard back. Vehicle was in motion when failure occurred causing sudden speed drop on a major highway, no injuries reported but accident prone.
