2020 Subaru Outback Transmission Problems

While driving on the NYS Thruway (I90), I started to pass a Tractor Trailer, I put my blinker on and began moving to the right to pass. There were 2/3 cars in back of me also passing. I was using cruise control and I began to put my foot on the accelerator to finish my passing and move over to the right hand lane to let the other vehicles pass me.

In January 2022 I received a recall notice on my 2020 Subaru Outback. I immediately contacted the nearest Subaru service facility (which happens to be about 30 miles away in Ft Myers, FL). I spoke w/someone in the service dept., and was advised that they, the svc.

On December 28, 2025, my 2020 Subaru Outback lost the ability to engage any gear (Drive, Reverse, or otherwise) while maneuvering at low speed to make a U-turn. The vehicle became inoperable immediately and was towed to the dealer.

Battery died at only 10months old. Left stranded for over 4 hours in remote area since we were camping when it happened. Nothing had been left on in the vehicle.

I'm writing to request assistance with my recall. This recall was first reported to the local dealership over one year ago. They have had me take the car back 4 times for inspection.

The contact owns a 2020 Subaru Outback. The contact stated that while attempting to make a turn, the transmission was slipping while attempting to shift gears. There was no warning light illuminated.

The car shifted (transmission) into neutral when cruising down the interstate at 62 MPH and stayed in neutral until the ignition was turned off. With no brake light cars were not worn and was nearly hit from behind. 2 weeks earlier the same happened on a city street. There was a previous transmission recall WRK-21Chain Slippage Recall on this vehicle that apparently didn't correct the problem.

Vehicle had 45,000 miles on it when right rear wheel bearing failed. It was covered under 5 year/60,000 mile warranty and was repaired today by a certified Subaru dealer and I no longer have the bad part for inspection. Safety risks would be anything that occurs from a bad wheel bearing like wobble, seizing, overheating, and more damage to other drivetrain components. You could hear the wheel bearing noise at 20 mph constant while driving, only getting louder with increased speed. No warning lights were present on the dash. I feel like at 45,000 miles, a wheel bearing should not be failing.

The contact owns a 2020 Subaru Outback. The contact stated that while his wife was accelerating from a stop at approximately 10 MPH, the vehicle stalled. The vehicle failed to move. There were unknown warning lights illuminated after the failure. The vehicle was towed to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The dealer informed the contact that there was no warranty coverage on the vehicle. The dealer confirmed the vehicle was not covered under NHTSA Campaign Number: 21V955000 (Power Train). The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 70,158.

The contact owns a 2020 Subaru Outback. The contact stated that upon taking the vehicle to the dealer to be serviced, the dealer informed the contact that the transmission was binding and making an abnormal grinding sound while driving at slow speeds and making turns. The dealer performed the TCM software update and replaced the transmission clutch kit under NHTSA Campaign Number: 21V955000 (Power Train); however, the failure recurred. The contact stated that the recall repair had failed to correct the failure. The vehicle was taken back to the dealer, where the transmission clutch pack was replaced twice; however, the failure recurred. The vehicle was taken to a second dealer, Schumacher Subaru (3021 Okeechobee Blvd, West Palm Beach, FL 33409), where the transmission clutch pack was replaced; however, the failure persisted. The vehicle was taken back to the second dealer, where the transmission clutch pack was replaced. The contact stated that the vehicle was temporarily repaired. The manufacturer was notified of the failure. The failure mileage was approximately 21,869.

On [XXX], I was driving east on [XXX] on the North side of Toledo Ohio close to the intersection with [XXX] . The "Check Engine" warning came on, all the vehicle "Eyesight" functions were automatically turned off, and Pre collision braking and Pre collision throttle control features were activated. There was no danger of a collision at this time, but all of this left me stranded in the middle of this busy four lane highway. I was able to literally crawl to the shoulder of the road. I was not hit, but it was just good fortune that prevented that. This is where my safety was at greatest risk. After about 10 minutes during which I started and stopped the car numerous times, the pre collision braking and throttle were deactivated and I was able to drive the car. I located the nearest Subaru dealer (Yark Subaru Toledo, Ohio) and drove there. The cause of the Check Engine light was diagnosed as a failure of the Thermal Control Valve. I had received a letter from Subaru dated May 1, 2024 stating that this part might fail and extending the warranty for this part. That letter specifically stated that nothing needed to be done until the part failed. There was no mention of the fact that the car would be disabled when it happened. Part was eventually replace on July 1, 2024 two days later. Since then I have spoken to 3 people at Subaru of America seeking to understand why a Check Engine situation caused the vehicle to be disabled. I also asked the Service Advisor at Yark Subaru to explain. They have all been friendly and attentive, but they cannot or will not give an explanation. My main concern is that a Check Engine situation may cause this Pre Collision shut down to happen again. Based on the danger I was in when this happed, I think that there should have been a recall and the Thermal Control Valve replaced before failure. To be clear, the repairs were completed under warranty and Subaru has sent me a $350.00 coupon for future service.

Thermostat Replacement: THERMO CONTROL VALVE IS NOT OPERATING. FLUID IS LEAKING FROM ASSEMBLY. The thermostat is a valve that keeps coolant circulating in the engine until it reaches normal running temperature. When this happens, the thermostat opens and allows coolant to flow to the radiator. There were no warnings before this occurred and my car could have overheated. After talking to multiple subaru outback owners, this issue seems to be predominant and am surprised it is not covered by Subaru or that the NTSHA has been warned of this issue.

[XXX] recall , Chain is slipping , Subaru Dealer In Boone NC Recommends [XXX] repair kit. Dealer, Hendrick of SouthPoint, Durham NC, won't cover expenses, because when they did the original procedure, [XXX] noted nothing was slipping at the time, and they updated the TCU and stamped completed. Now that the car is over 100k miles by just a few thousand they will not repair it. Cost to repair $12000.00.

Thermo Control Valve assembly has failed resulting in loss of use for the following: Rear Automatic Brake, Eye Sight lane keeping, loss of heat in cabin and failure of coolant to circulate within engine possibly leading to engine failure, loss of cruise control and check engine light coming on. Reference TSB [XXX] . Without cabin heat vehicle is not useable in current cold temperatures (Currently 22 degrees Fahrenheit in Ohio on December 14, 2023). Dealer has confirmed part failure. Issue must be addressed to continue operating vehicle so I paid $1185.87 out of pocket to repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Thermal control valve failed leading to temperature problems and loss of safety features such as automatic braking and adaptive cruise control otherwise known as “Eyesight”

Car lurches when put into gear, Transmission make loud chirping noise when place into gear from park, transmission shudders when turning. Car has had all recalls updated. Symptoms have been reported to dealer numerous times.

Two issues. Main cabin computer reboots randomly. This causes other safety systems, Eyesight, to stop working until the device boots back up.

On 3 separate occasions, my transmission has switched from automatic mode to manual “Auto-stick” mode on its own with no input from me. There were no warning lamps or error messages, and the gearshift was still firmly in Drive. This has resulted in 3 near-miss accidents because the car landed in 1st gear even though I was going about 30 mph each time. From my experience driving manual transmission vehicles, I know what happens when a moving vehicle is suddenly jammed into 1st gear—it comes to an immediate, violent stop. On all 3 occasions, I was lucky not to have other cars behind me. But I know I won’t be so lucky forever. Sooner or later, I will be rear-ended when this happens. I have taken the car to the dealership twice for inspection. They told me that they had never heard of nor seen any vehicle doing what I described. Technicians drove it 7 miles and reported no incidents. I knew it was unlikely to happen on command since it has occurred 3 times in 32,000 miles. They told me that Subaru requires dealerships to reproduce issues before undertaking any repairs. Therefore, they returned the vehicle and told me that it absolutely could NOT change modes unless I had bumped or moved the gearshift. Less than 2 weeks later, the defect happened for the third time. I returned to the dealership and insisted they look further into the problem. I involved the Service Dept manager so that my complaint might be taken more seriously. There is an open recall on the transmission for slipping but they said the 2 issues were unrelated. This time they kept the car for a week and drove it 46 miles. They connected a diagnostic computer to the transmission while driving it. But again, I was told since they witnessed no problems, they could do nothing more. I showed them a blog on Edmunds.com from Subaru owners reporting this exact issue beginning in 2011. Owners have taken this to Subaru many times but new cars still do this. Please help. I’m at my wit’s end. Thank you.

Transmission broke while vehicle was in motion. I was unable to move the vehicle any further and drifted to a complete stop in the middle of the roadway.

Date: March 25, 2022 - While driving to work, the car shut off. The RAB and eye technology features were disabled. The car indicted the battery was drained. The same day I got the car towed to the dealer. I stayed with the vehicle to find out what was wrong. After a two hour inspection, the Bay Ridge Dealer/Mechanics in Brooklyn, New York indicated that I left something on that drained the battery. I said sir "I did not." He said well the battery is ok and there is no indication that anything is wrong. The next day (March 26,2022) when I was about to start the car - the car couldn't start. I had to get it towed to the dealer and am left without a car.

The contact owns a 2020 Subaru Outback. The contact stated that he received a recall letter from the manufacturer. The contact stated no warning light was illuminated. The contact took the vehicle to a local dealer, where it was diagnosed with needing a software update. The contact reported that the recall letter advised that the vehicle has no remedy for it yet for the CVT chain. The contact said that the vehicle will be unsafe to operate and the dealer nor the manufacturer have offered any remedy. The vehicle was not repaired but was pending repairs. The manufacturer had been informed of the failure. The failure mileage was approximately 23,000.

We received the recall notice and do not feel safe driving the vehicle. This problem has the potential to seriously injure or kill someone if the vehicle failed on the highways. They quote May as the earliest time frame that they will begin repairs. This is not an acceptable time frame. Assuming the dealers are prepared in May, there could still be an overwhelmingly long wait list for the needed repairs. This could possibly lead on well into summer before my vehicle is in the shop. What are we to do for transportation in the mean time? Are we to continue driving as usual and risk our lives or those of fellow motorists near us? I would like a mitigating solution as we do not have faith in our safety if we were to operate the vehicle any further.

Since purchase, the transmission occasionally slipped and "clunked". Over the past few months, it has become worse, and now, with increasing frequency, grinds vibrates and shakes. It was taken into the dealership and nothing was done to fix the problem. We feel it represents a clear and present danger that could result in a severe accident.

3 months ago the 2020 Subaru outback required a rebuild of the transmission at about 50K miles. I was told it was due to uneven wear on the tires. They would not fix it until I replaced all 4 tires costing $600 which I did.

I bought my Subaru Outback in July 2020, it’s barely one year but I already had two major problems happened to the vehicle. The transmission was broken, it’s confirmed by the dealership and they were able to replace the whole transmission system for me.

MY 2020 SUBARU OUTBACK IS EQUIPPED WITH THE “AUTO-START-STOP “FEATURE. FROM THE BEGINNING THIS FEATURE WOULD ROUTINELY NOT FUNCTION, DISPLAYING THE ICON INDICATING AUTO START STOP WAS DISENGAGED. WHEN ATTEMPTING TO UTILIZE THIS FEATURE I LEARN TWO MORE DELIBERATELY HOLD DOWN FIRMLY ON THE BRAKE PEDAL AND I COULD ENGAGE THIS FEATURE AT TIMES. NINE TIMES OUT OF 10 THE AUTO START STOP FEATURE DOES NOT ENGAGE WHEN I STOP IN DRIVE WITH MY FOOT ON THE BREAK AT A TRAFFIC LIGHT OR AT A STOP SIGN. VERY OFTEN, THE FEATURE TURNS OFF MY ENGINE AND IMMEDIATELY RESTARTS WITH A RUMBLING OF THE ENGINE AND AN ABRUPT “KICK“ TO THE STEERING WHEEL. EVEN WHEN THE FEATURE ENGAGES AND SHUTS OFF THE ENGINE AS EXPECTED, THE DURATION OF STOP MODE IS A LIMITED TO NO MORE THAN 20 SECONDS WHICH DEFEATS THE ORIGINAL INTENDED PURPOSE OF FUEL CONSUMPTION AND EMISSIONS REDUCTION. OCCASIONALLY AT A TRAFFIC LIGHT, SUCH AS WHEN WAITING TO MAKE A LEFT IN FRONT OF ONCOMING TRAFFIC, THE FEATURE DOES NOT ENGAGE AT FIRST STOP AND AFTER INCHING FORWARD AND READY TO MAKE THE TURN THIS FEATURE WELL ABRUPTLY STALL THE ENGINE AND STRAND ME MOMENTARILY IN FRONT OF ONCOMING TRAFFIC.

I received notice of this recall in February 2022 and nothing has been done. Meanwhile I fear that my car is experiencing the problem that it addresses. What good is a safety recall as serious as this one may be if the manufacturer is not going to promptly address the problem?

******* delete voq ******* this complaint is being marked for deletion because the consumer placed the request.*djr ******* delete voq *******

Have been experiencing issues with the transmission for 6 months. Still have not been provided a remedy to correct the issue.

The car has a faulty electronic system that controls the stability and the adaptive cruise control. Transmission also needs replacement. Problems happen at high speed on freeways.
