Just bought my wife a 2019 outlander sport, has 30k miles on it and she told me that she parked on a gravel incline and went into reverse and the car would not move easily, so she puts it in drive, same thing like the parking brake is on but it's not, puts it back in park and then to reverse again and it works. So I take it out and try to replicate the problem and after 4 or 5 times on a gravel incline it does it to me too I get out have my wife give it gas and see that the rear passenger tire is locked up and tell her to put it in drive, same thing then back to park and reverse again and it works fine. Any ideas why this is happening? The car is in 2wd as far as I know and we just got it I know nothing about Mitsubishis but my friend has a 2wd outlander and has not had any issues with it so I thought I'd give it a shot. Anybody have this issue or know what's going on here?
