2020 Chevy Traverse High Country Exhaust bank 1 and bank 2. Transmission shudder.

Receiving a persistent “Shift to Park” message, after the car has been placed in Park. This causes an inability to turn off my engine completely and is draining my battery. As a temp fix, I've had to wiggle the shifter many times, turn the car on and off, place the car from park into drive many times to get the car to realize it's in Park. Scheduled with the dealership and referenced the TSB that was issued for this specific safety issue (in writing). Brought the car in for the repair and the technician and intake person were both aware of this major problem and have seen other Chevy's with the same issue. Repair is $809.00 for a shifter assembly.

Vehicle started to show error for shift to park. Not able to shut vehicle off. Vehicle drives fine but when I go to park and vehicle is in park. I go to turn vehicle off and error appears. I called dealership according to them just to look at vehicle its going to cost me $275.. For everything else $1,100. After reading all the complaints on this issue why has manufacture done anything. Obviously this is a well known problem I've always loved my chevy

July 2025 the transmission started stuttering. Took to an outside transmission shop, report showed torch converter failure.

I recently had to replace my transmission (2020 Chevrolet Traverse) due to shuddering from manufacturer's fault in assembly process. Now I'm having to replace the transmission in my mother's 2018 Chevrolet Colorado that has less than 65k miles. These issues cause power loss while driving. I was in the middle of passing another vehicle when my vehicle experienced power loss. This is a HUGE safety issue, not only for my family but many others that I know that are experiencing or have experienced the same issues. I have 3 family members that have had to have the same repairs as well as over 40 acquaintances. I had assumed with the thousands others that I've chatted with on facebook and reddit that this would have been a recall, sadly, GM/Chevrolet doesn't seem to care that it is their fault that their consumers are having to spend THOUSANDS of dollars to correct an issue that leaves the manufacturer at fault. With the thounsands experiencing the same issue, i feel that those that have already had to spend money should be reimbursed.

The contact owns a 2020 Chevrolet Traverse. The contact stated that while parking the vehicle, the message “Shift to Park” was displayed and the contact was unable to turn off the vehicle. The contact stated that there was no warning light illuminated. Additionally, while driving at various speeds, the vehicle jolted abnormally while accelerating. The local dealer was contacted; however, the vehicle was not diagnosed since the VIN was not under an open recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 107,000.

Purchased the vehicle in 2024, the vehicle recently has been notifying “shift to park” when vehicle is on park and ignition is turned off, the notification stays on and alerting, so I am unable to leave the vehicle. I must turn the vehicle on and off again, while moving the shifting lever back and forth from drive to park, this must be done a minimum of four times before it reads the lever in park position. It’s a safety hazard because, the vehicle cannot be left on shift to park and possibly roll away or drive/excel on its own. Vehicle has not been inspected at this time, when purchasing the vehicle in 2024, car fax report did not indicate any issue with power train. Would also like vehicle to be inspected for missing airbags, when driving 65mph or more, you can hear and feel air coming in and out of side front left passenger side of the vehicle.

See GMBulletin #19-NA-206 I am getting the "shift to park" warning which makes it difficult to turn off/safely park my vehicle. I know the NHTSA is aware of this as well as numerous lawsuits in progress against GM for significant safety issues. Will this go to recall status soon?

The Transmission went out at 128k miles, a BRAND NEW GM transmission was replaced at a cost of $6,800 to me as it was not under warranty. Less than 2 months and 2k miles later, the new transmission went out. I just got my car back yesterday with yet another GM transmission and once again it is jerking, so I’m sure another faulty transmission from General Motors

Vehicle would not start. Towed to repair shop. 350A fuse blown that controls ignition system. Pulled starter to inspect for damage. Transmission Flex Plate had 7 broken teeth with a tooth being lodged in the starter housing.

Severe transmission shudder, issues accelerating. Torque converter failure is very common with this vehicle, even with following routine scheduled maintenance. There is no engine or MIL light on and symptoms appeared out of nowhere. Failing to be able to safely accelerate can cause accidents, putting lives and property at risk. Looking information up online will show that this is a very common issue with this model year and transmission.

The transmission on my 2020 Chevrolet Traverse has experienced severe shuddering problems when shifting gears. The vehicle is not old and the integrity of the safety of the vehicle puts myself and my family at risk whenever driving it now. The dealer quotes approximately $8,000 for a fix and a similar search online sees other customers with the same issues. Chevrolet should recall the affected vehicles and not force the consumer to pay out of pocket for the repairs.

The flywheel teeth broke off and became jammed in the starter, which apparently caused a short to the fuse block. The dealership hasn’t commented on exactly what the root cause was though for why that may have happened. I don’t have the original part(s) but the dealer might. I was in the car at the time with my entire family. We were in the middle of driving everyone home from school. The power to the car stayed on but the engine completely died. Given we don’t know what happened with I’m terrified the starter may have tried to engage while driving which would have broken the teeth off. The problem was confirmed by the dealer only in the sense that the parts were broken, but they don’t have root cause. The vehicle was never inspected by insurance as it still fell under the 100k mile certified pre owned warranty. No warning prior to the incident but after there was one brief message that came up saying we needed to check engine system.

While taking off after being stop the alclenton the tramssmion slip into gear late and you can notice it while foot on pedel after u take off oil was.change but still the same delership says it comon with this suv

2020 traverse was at Chevy dealership for state inspection & emissions test, maintenance service- oil & filter change, rotate tires, check all systems, update system & computer, flush & fill all fluids in car. Chevy certified technician preformed vehicle health inspection, multi point inspection . Car was not picking up acceleration will on a 351 mile trip alone, after stopping I notice the car hood was not on correctly when opened the oil cap was not in place but was on molding, oil had been pouring out leaving engine with no oil, the technician had not replaced cap during service and had no replaced brake fluid, antifreeze coolant, washer fluid and transmission fluid. He had force closed the hood, which could have opened at any time while driving, there was oil pouring from vehicle causes hazardous driving for myself and everyone else on highway. Car has OnStar coverage as well as Chevy safe driver function’s, and alerts on all systems all fluid levels, tire pressure, temperature ext. non of these alerts showed or alerted me putting my safety and the safety of others on the roads in danger. The technician in fact disarmed these systems and alerts when servicing my vehicle. Ciocca Chevrolet dealership in Quakertown pa, caused permanent damage to the engine and power train system, as well as putting myself and others in serious danger. The car was towed by OnStar roadside assist back to dealership where they tried to down play the severity of the damage . I refused to take back the car due to it not being drivable or safe. The service manager agreed to buy out my loan and the car is on lot for sale with tag stating ‘sold as is , no warranty” . Due to the computer system being compromised there is no data showing the service or showing the car being in distress , this issue needs to be know as driving this vehicle with out knowledge of engine damage caused from dealership failure to add all fluids during service puts driver, passenger’s and all others in danger.

The car has started to show a "Shift to Park" message on the dashboard when turning off the car. The car won't shut off until you give it a couple minutes and try again. This seems to be a consistent error with chevrolet models with a few years older and newer getting the recall.
