The torque converter in the transmission has failed it has currently been sitting at the dealership for 3 months do to supply chain issues. The dealership has confirmed the problem along with my auto insurance company as well. Prior too there was smoke with a bad odor coming out of the vents in the vehicle that could have caused me and my kids health issues dealing with breathing had we continued to drive the vehicle. There was no lights to indicate what the issue was. Only the fumes. The fumes came out from what the dealership stated was because of the clutch burning in the torque converter. This is a major issue that could kill someone if they inhaled to much of the fumes.

When the vehicle was turned off, a message appeared: Shift To Park. The red light on Park also remained on. I had to shut down the vehicle multiple times before the message disappeared. One time I just "jiggled" the shifter and the messaged disappeared. The message did not appear whenever I turned off the vehicle, only sometimes. However, it appeared more often than not. It did appear when the service representative at the dealer moved the vehicle and turned it off. The remedy was to replace an SL-N-Switch (04054-CT) and a N-Harness (02480-CT). The cost to remove the shifter and installed these parts was $360.26. The service representative advised me that this problem could run down the battery. It is a safety issue since the battery could run down if the car was exited and the message stayed on. I found a technical bulletin from GM ([XXX], September 2019, entitled "Intermittent Shift To Park Message Displayed While Vehicle in Park for a 2018 Traverse and another technical bulletin with the same reference for May, 2021. I believe that the 2019 and 2018 Traverse share the same drive train. I also found a forum online: [XXX] that describes what other customers have found with their vehicles.

When shifting into park, the vehicle does not recognize the shifter has been moved to the "park" setting. An alert will sound stating the vehicle must be shifted into park position. We then have to shift out of park and back into park...sometimes multiple times, before the vehicle recognizes that the shifter is in the Park position.
