| Power Train problems |
Our vehicle became unable to shift out of neutral after a traction event (wheel slip & loss of traction) when trying back into our driveway from a snow packed access alleyway then multiple system warnings occurred including transmission, traction control, abs, engine ecu, stability systems and anti-roll errors. I turned off the car and tried again with vehicle still unable to shift out of neutral with the multiple system warnings again occurring. I turned the vehicle off for a longer duration (10 minutes) while calling the service department at the dealership asking if our car should be towed. I turned the vehicle on again and it did go into drive and reverse but the check engine light displayed. Remote start no longer functions. Failsafe modes are not supposed to leave the car unable to shift out of neutral without warning! the fact that it threw multiple system errors at once, refused to shift, then later shifted after a longer power-down, and now has a check engine light strongly suggests a stored hard fault, not just a transient glitch. From a safety and regulatory standpoint, loss of motive control without driver input amounts to a reportable safety defect. if this didn’t happen while trying to park in my driveway, it could’ve been much worse. If this had happened in traffic, while pulling into an intersection, on a hill, during a snowstorm, or while backing into traffic, the inability to shift could have caused a collision. I did report this to vw customer care and they immediately escalated this to a case manager. The vehicle was dropped off to the dealership this morning and will be discussing the event with the service manager on Monday and that I want all stored fault codes printed, confirmation whether this triggered limp/failsafe logic, and what prevents it from happening again. the vw case manager will also be contacting the dealership directly. The bottom line is that I do not feel safe operating this vehicle until the root cause is identified. .
