Consumer Description

Went into limp mode on 11/6/25, took to the dealership where they found metal shavings in the oil due to a “stuck solenoid ‘A’”. Originally said that I’d need a whole new transmission, decided to do the cheaper easier repair and just replaced the valve train (not my choice) got it back on 11/13/25. On 11/24/25 I was on a very busy highway, at a red light, hit the gas when the light changed and the car didn’t move. Just revved the RPMs, then it suddenly lurched/surged forwards. Took it back to the dealership and they said “it doesn’t have any codes showing”. This is not normal behavior for a 4 year old vehicle with less than 40k miles on it.
