Open the full vehicle complaint log (all categories)Vehicle shudders and surges while driving almost rubber banding. Mechanic showing code for fluid pressure sensor. Call to local Mitsubishi dealer said transmission needs to be replaced and since we are 2nd owners the 100k mile powertrain warranty doesn’t apply. This vehicle has 81k miles and it’s already fried and Mitsubishi doesn’t care unless we buy a new one.
The transmission has a severe shudder and lack of power. The malfunction occurs frequently and most recently has occurred while making a left turn in an intersection when the vehicle suddenly stumbled in the middle of the intersection with oncoming traffic nearing. The problem has been confirmed by Mitsubishi with a TSB released regarding the affected vehicles TSB-22-23-001REV, however, they refuse to do anything since the vehicle is no longer under warranty. The check engine light appears when the issues occurs, code "P084a" along with the "Service Transmission" indicator on the instrument cluster.
