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. Since that time as the problem has proceeded to get worse, which will now cost even more to repair, and increase the likelihood of the transmission damaging other parts of the drivetrain. Now I just received notification that they will not perform the recall as my vehicle doesn’t qualify. It has the problem of transmission slipping which is what the recall is for. I saw the pictures they took that looked exactly like the problem specified. I do not have $7000 dollars plus to fix the transmission. I can’t sell the car because the VIN will show the recall (which I’m sure they will try to just remove). All they have done is waste my time for the last year to do what? Gather enough evidence to try and get out of the recall?

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. The dealer confirmed via text and written estimate that there was no external damage, the failure was internal to the CVT transmission, and the transmission requires replacement. This vehicle has approximately 90,023 miles. The failure occurred under the mileage and age range covered by Subaru CVT warranty extensions for similar vehicles. Subaru of America reviewed the case and denied coverage, citing VIN exclusion and prior service gaps that predated my ownership. The vehicle is currently inoperable and presents a safety risk due to loss of propulsion. I am reporting this to NHTSA because it may indicate a systemic defect in CVT transmissions on this model year Outback.

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.

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.

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.

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.

Vehicle was taken to a dealer to perform warranty work related to Subaru MSB 16-136-22R on 7/6/2022, at mileage 18,317. Owner was experiencing vibrations and noise on turns during acceleration, first noticed a month earlier, which was steadily becoming worse, causing concern about the safety or possible failure of the vehicle. Dealer confirmed this problem existed in the multiple plate transfer (MPT) clutch and attempted temporary repairs, as per the service bulletin. Repairs were unsuccessful and vehicle status was then said by the dealer to be “off-road — not drivable”. The dealer indicated the front transmission had failed. Parts were ordered at that time from Subaru to do the repair. The vehicle has been in the dealer’s possession since 7/6, waiting for parts to arrive.

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. dept., have not received parts yet, but expect them in a few weeks. I waited about 8 weeks before calling them again, with the same results. Now, I treat Vehicle Recalls like a doctor's advisory. I take it to mean what it says and that it's IMPORTANT. Now, here we are in June 2022, and still NOTHING from Subaru of America, nor the Ft. Myers service department. Is it still a Vehicle Recall(?), must be because I've heard nothing to the contrary. And, if I've heard 'nothing to the contrary', why hasn't the US Dept. of Transportation followed up w/Subaru of America. SIX MONTHS is a pretty long time waiting to avoid an accident!

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?
