2022 Porsche Taycan transmission problems

Filed Oct 18, 2026 · Electrical, Fuel system · GA

Vehicle experienced a sudden, complete loss of motive power while driving in active traffic at night, creating an immediate crash hazard. The vehicle had just been picked up from an authorized Porsche Service Center approximately 12 hours prior (picked up between 11:00AM - 12:00 PM, failed at 11:09 PM) after undergoing a comprehensive 60K mile scheduled service and a mandatory manufacturer software recall campaign. Without warning, the vehicle completely stalled and dropped into an undriveable state. The driver’s instrument cluster immediately illuminated two major critical alerts: "Transmission failure" and "Engine control error." Because the vehicle was stranded dangerously in live traffic, local police were dispatched to assist with safety and traffic control (Police Incident #XXX). The vehicle had to be urgently towed from the roadway at an out-of-pocket cost of $300, and it has been returned directly to the authorized Porsche service center in [XXX].

While driving in traffic on a busy highway, I heard a loud clunk from the rear of the car and it instantly decelerated from 70+ miles per hour to 22 miles per hour, where it stayed and would not go faster. I had to get across 3 lanes of traffic to exit. Thereafter, the car would not move and had to be put on a flatbed to get to the Porsche dealer. Note that for 2 years prior the transmission had emitted a whine while in first gear. The dealership (Porsche Austin) said it was normal, but it is a known problem among owners, possibly related to the input shaft bearing. They did not fix it when the problem was first raised. The dealership has diagnosed it only as a transmission error, without providing further detail on what is actually wrong. I should be able to access my dash cam footage if helpful.

Driving at 45 MPH, and suddenly the car lost the ability to accelerate. It has no power/torque. It seemed to be able to maintain the speed (but not entirely sure or if it was coasting). I had limited areas on the road to turn so took last possible turn to pull over. A shutdown/start corrected the situation. No warning lights or indicators of any kind appeared. Cannot reproduce, which makes this situation more frightening. No other symptoms or warnings before.

While driving on the city streets, the vehicle would not accelerate properly. At a stop sign, when pressing the accelerator, the vehicle started to jerk forward slowly and would not accelerate properly. A turtle started to flash on the cluster display. Trying to get to a safe location, the vehicle kept jerking forward slowly while slowly increasing speed and flashing the turtle icon.

While driving on the freeway at 65 mph, the vehicle suddenly began to quickly decelerate. Pressing the accelerator pedal had no effect. The car behind me quickly swerved to avoid hitting me. I was able to maneuver the car onto the shoulder and very slowly exited the freeway. I noticed a warning light shaped like a turtle on the cluster display flashing. I stopped fully and turned off the vehicle. The car was then towed to the nearest Porsche dealer. One week later, the dealer was inspected the vehicle and was unable to reproduce the issue. No repair was performed and Car was returned.

While the vehicle is in both Drive and reverse, the car randomly will shift itself into either neutral or park without warning. The first event occurred while in reverse and actively moving, the car shifted into neutral on its own. No warning lights or messages appeared. The following 2 incidents, while driving on city streets, at a stop sign in one instance and at a stop light in the other, the car shifted into park within seconds of the vehicle coming to a stop. Also, no warning lights or messages occurred. I have contacted my local Porsche dealer to see if there was any service bulletins or a know fix, and was informed that by the service advisor, that she believes this is normal operation because she has heard of it happening. This situation has been dangerous each time it has happened, as I was in traffic, and unaware that my vehicle no longer in gear until I tried to accelerate, and my car was unresponsive. I can’t imagine how your vehicle not being in the gear you put it in, is not a safety concern. I also fear that the vehicle may go into park while at highway speeds, and be catastrophic.

When the car was in Drive (D) mode but stationary at a red light, it abruptly went in to park (P) without any user intervention. Had to reengage the drive mode to move forward. Problem has occurred at least twice before (months apart) without any reproducibility. I did bring it to the dealer once but they did not find any abnormal logs. Latest occurrence on 7/6/2022 at approximately 6:15 PM Lost power steering assist completely in my driveway while backing out of the garage in reverse mode. No warning signs on the cluster. Could not turn the car. Only way to get power steering assist back was to turn off the car completely, wait for 10 seconds and turn it back on again. Incident happened on 7/7/2022 at 7:45 AM
