Only 3 out of 4 doors open, the outside door latches have failed since purchase in 2013. Have also continually failed/re-broke after being fixed. Car also does not unlock after being locked and inside door mechanisms do not unlock after being engaged. . Huge safety issue. Also multiple times the a solenoid has to be replaced due to the car does not shift correctly and fails to accelerate safely (takes a over a min to go from 35-60) and even then it will not maintain 60 miles per hour going up a hill . This is a automatic vehicle , and it is unsafe , especially when exiting off a onramp trying to excel to posted speed limit to merge into traffic off the ramp. I have had multiple problems/issues with this vehicle since its purchase and it is a very unsafe vehicle.
