2020 CHEVROLET TRAVERSE Power Train Problems

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.

Slipping in low gears of transmission. Shaking of vehicle. Potential to break down.

Check engine light came on day after I purchased this vehicle. Cracks in both front exhaust pipes. Seem to be an issue with 2020 chevy traverse models.

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.

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.

Ive got this vehicle on 5/12/2025 and all of this need to be done CATALYTIC CONVERTER REPLACEMENT. DURING INSPECTION FOUND LOUD EXHAUST ON STARTUP. UPON FURTHER INSPECTION FOUND BANK 1 CATALYTIC CONVERTER CRACKED CAUSING EXHAUST LEAK. BOTH EXHAUST FRONT PIPES DAMAGED AS WELL(BROKEN MOUNTING BRACKETS BETWEEN BOTH PIPES) .

I am sure this was an issue to begin with.

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

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.

Mileage: 107,000

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

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.

[XXX] [XXX] [XXX] [XXX] 4/16/2025 General Motors Customer Assistance Center P.O. Box 33170 Detroit, MI 48232-5170 Subject: Power Steering Issue – 2020 Chevy Traverse (VIN: [XXX] ) To Whom It May Concern, I am writing to express my concern and frustration regarding a serious issue with my 2020 Chevrolet Traverse, VIN [XXX] . On [XXX], while driving, the steering wheel suddenly became very stiff, making it extremely difficult to turn right or left. A warning message appeared on the dashboard that read: "Reduced Steering Assist." I immediately took the vehicle to a certified dealership, where it has now been sitting for over two months. Despite multiple follow-ups, I have not been provided with a clear repair date. When I contacted the manufacturer, I was informed that the required part is currently on backorder, but again, no estimated time of resolution has been given. During this extended wait, I have been forced to rent a car to manage my daily responsibilities, and so far I’ve accumulated close to $1,000 in rental expenses. My case number is: [XXX]. I am requesting the following: 1. A clear update regarding the repair status of my vehicle. 2. Urgent assistance in obtaining the necessary replacement part. 3. Reimbursement or compensation for the rental car expenses caused by the extended delay, which has not been my fault. I trust that General Motors values its customers and the reliability of its vehicles, and I hope for a prompt and fair resolution to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

TRANSMISSION CHATTER AND SLIPPING. I WAS NOT ABLE TO SECURE AN APPOINTMENT BEFORE MY WARRANTY EXPIRED. ATTEMPTED TO CALL GM FOR ASSISTANCE AND THEY WANTED TO CHARGE ME FOR DIAGNOSIS AND COULD NOT ASURE ME OF ANY ASSISTANCE AND SINCE I HAD A DIFFERENT ISSUE WITH MY CHECK ENGINE LIGHT DUE TO FAULTY CATALYTIC CONVERTER THAT WAS UNDER WARRANTY AND I WAS CHARGED AND DID NOT GET MY MONEY BACK, I WENT A DIFFERENT ROUTE. THE DEALER ACTUALLY WANTED TO CHARGE ME TO REPLACE THE CONVERTER. i HAD MY TRANSMISSION REPAIRED AT AAMCO $6000.00. KNOWN ISSUE WITH THESE TRANSMISSIONS BY MANUFACTURER.

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

The car displayed a message on the board advising the following: "Steering assist is reduced, drive with care" right after the message popped out my steering wheel locked and I couldn't turn, and move the car to a safe place was very hard, almost had a crash. I was able to park, and turned the engine off. When turned back on the message disappeared and turned on again. Next day, no message, the car was running fine and after 8 miles of drive did the same and it required towing.

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?

1 year after buying my car two of my seat belts stop working one was the back driver side the clip doesn't stay in sometimes and then the middle seat and middle belt got stick in the seat and I wasn't able to pull it out to use it. I bought my car in Dec of 2020 and in October of 2024 my whole transmission went out which I never had any problems before not even a warning sign, I took it to a mechanic since it was only driving in first gear and they said it might be from the inside of the transmission when it was made they solenoids are bad.

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.

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.

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.

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 contact owns a 2020 Chevrolet Traverse. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle shuddered. In addition, the contact stated that the gear shifter sometimes failed to shift into the intended gear. The vehicle was taken to the dealer; however, the vehicle was not diagnosed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 120,000.

Mileage: 120,000

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.

The transmission failed in the middle of me driving the check engine light popped on and started jerking and accelerating and slowing down in the middle of traffic. It is available for inspection. Stopping randomly and jerking as soon as the light popped on. I am about to be out of thousands of dollars for a 40000.00 car that I'm still paying on always kept maintenance up and just had an 180.00 inspection at dealership prior to this no mention of a transmission failure prior. Everything came back good so this is frustrating several other 2020 traverses have been recalled due to transmission I am not sure how mine isn't included for same year. It conveniently happened right when it wad out of warranty.

The transmission went out, when going out it causes the vehicle to jerk while at a high speed of 60mph and then after the jerking it stops in the highest gear almost causing a wreck and this all suddenly happens on an interstate.

Alternator failing and needing to be replaced on a 2020 Chevy Traverse with only 33,000 miles. Seems to be a common issue with several Traverse and it's a costly repair as it's past warranty.

My vehicle along with many other make a stuttering feeling when accelerating at low rate of speed. This can lead to a bad transmission and causing the vehicle to cut off making a hazard.

In the past 3 years I have received 2 check engine lights giving a code of P0420, meaning the catalyst system efficiency is below threshold. Chevy replaced my catalytic converter in April of 2022… now a year and a half later they need to replace parts again. A catalytic converter is an important exhaust and emission component that is designed to burn up the toxic exhaust gases that come from the engine… carbon monoxide and hydrocarbons to be exact. I just found out today after taking it in for a second time that the first replacement of the catalytic converter was a defect on the manufacturers part. Every time I go in I have to pay the diagnostic cost and I feel as though I was sold a defective car. Catalytic converters are supposed to last the cars lifetime in some cases.

This vehicle has completely lost power and stalled on the freeway twice. The first time, I was with my wife and children when it happened on the highway. The vehicle stalled in the far right lane of traffic and it wouldn't restart. We had to risk our lives and push the vehicle off the freeway and onto the shoulder while other vehicles raced by. We are fortunate that we did not die or become seriously injured. The second time the vehicle stalled on the highway, my wife was crossing the highway and the vehicle once again lost all power and shut-off. She is fortunate that she was not killed in a T-bone collision. The first time, there was a dash warning stating to SERVICE ESC. The second time, there was no warning lights or dash illumination of a problem beforehand. The vehicle has been taken to the Chevrolet dealership twice. They ran a diagnostic and stated the starter was pulling too many amps which caused the vehicles fuse block to blow, resulting in total failure of all vehicle components. Total repair cost for first repair was approximately 1,000 dollars. We are awaiting the service advisors diagnostic for this second incident. The first repair is covered under a 2 year unlimited mile warranty so hopefully when they replace the starter and fuse block this time, they will also find the root cause of the problem. I feel as if our lives and well-being are in jeopardy since the first incident and we no longer feel safe driving this vehicle which has stalled twice during highway conditions. I am confident that we will no longer be GM consumers due to these life risking incidents.

Transmission shudders when warmed up. After driving Transmission will shudder pulling hills. It becomes worse and more noticeable the longer it is driven and when hot out. Numerous times after driving for a few hundred miles and then stopping, the vehicle will shudder trying to take off. Has been back to the dealership 4 times now for the same issue. First time was told it needed a torque converter, when taking it in to have the torque convertor changed a TSB was located advising to change the transmission fluid instead (January of 2022). After about 1000 miles issue has came back. Dealership is unable to duplicate it due to it being worse on hot days and unable to drive for long periods of times. There have been numerous complaints after researching online about this with the Chevy traverse. This vehicle has almost left me sitting in the middle of intersections due to Shuddering.

WHEN SHIFTING FROM DRIVE TO REVERSE, OR PARK TO REVERSE, THE TRANSMISSION WILL NOT ENGAGE RIGHT AWAY. THE VEHICLE WILL ROLL FORWARD OR BACKWARDS UNTIL THE TRANSMISSION ENGAGES INTO REVERSE. THIS WILL HAPPEN WHEN THE VEHICLE IS IN MOTION AT VERY LOW SPEEDS (1-2 MPH) AND ALSO WHILE STATIONARY.

Mileage: 3,300
