Defect. Subaru of America, Inc. (Subaru) is recalling certain 2019-2022 Ascent vehicles. The ground bolt that secures the ground terminal of the Positive Temperature Coefficient (PTC) heater may have been improperly fastened, which could result in melting of the ground terminal and surrounding components.

Risk. A melting ground terminal increases the risk of a fire.

Remedy. Owners are advised to park their vehicle away from structures and to avoid leaving the vehicle unattended while the engine is running. An owner who notices or smells smoke coming from the dash or driver's footwell area should immediately stop operating the vehicle and turn the ignition switch to the "Off" position. Dealers will replace the PTC heater ground bolts and if necessary, replace the ground wire and the connector holder, free of charge. Owner notification letters are expected to be mailed February 6, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRL-22.

After my husband replaced the 12V battery in my 2021 Subaru Ascent Touring ($90,000, fully paid off), Apple CarPlay stopped connecting via USB entirely. Android Auto and Bluetooth continued working fine on the same phone, cable, and port, proving the defect was isolated to Subaru's CarPlay system, not my device. I spent significant time and money troubleshooting this myself: multiple cables (including two labeled "Apple certified"), a full infotainment factory reset, and a software update attempt, none of which fixed it. The issue only resolved after I purchased yet another cable at my own expense, with zero meaningful help from Subaru. When I filed a formal complaint, I received a response with an appointment confirmation left entirely blank (no retailer, date, or time), which I was told was "intentional" so I could fill in my own details, shifting all scheduling and diagnostic responsibility back onto me. When I requested compensation for hours spent troubleshooting a defect that was never mine to fix, I was told plainly that no compensation exists. Shortly after, my key fob began requiring near-direct contact with the door and push-start button to register, despite a confirmed correct, brand-new battery, ruling out the simplest cause. This is a second unexplained electrical issue on the same vehicle in a short span. Subaru's support has been dismissive and apathetic throughout, repeatedly redirecting responsibility back to me as the consumer rather than taking ownership of

My local Subaru dealership / service provider has told me my car needs a new transmission at 66k miles, due to an issue within the CVT solenoid causing slipping and lag that will eventually lead to catastrophic failure of the transmission - per the Subaru of America service tree. This issue began on July 23, 2026, when a slew of warning lights illuminated on the dash and my car went into limp mode, not accelerating properly. It eventually began driving normally and all dash warning lights dissipated. Dealership couldn't see the car at that time, then I was out of town for about a week. Came back, experienced the same issues within 2 days of driving the car. I was able to get it into the dealership for service on 8/6 where it was diagnosed, according to the Subaru Service Tree, as needing a new transmission. Subaru technicians cleared the codes, and I took the car home on 8/7/26 with the warning from my dealership that it was only a matter of time before the transmission failed. The lights / limp mode driving came on again on 8/9 and I have not driven it since that date. I have opened a case with SoA and am waiting on a "resolution". I do not feel safe driving my vehicle so it has been sitting in the driveway since 8/9 while I wait on a resolution from Subaru of America.

The contact owns a 2021 Subaru Ascent. The contact stated that while driving at an undisclosed speed, the vehicle started to stall, and the transmission failed to properly operate. The vehicle was pulled over to a nearby shop and was advised to take the vehicle back to the facility that performed the oil changes. Several days later, the contact's husband test drove the vehicle and was able to duplicate the failure. The vehicle was towed to a dealer to be diagnosed, and metal shavings were found in the oil. The dealer determined that the CVT transmission needed to be replaced. The vehicle was being repaired. The manufacturer was notified of the failure. The failure mileage was 101,541.

On May 14, 2026, while driving a 2021 Subaru Ascent (approx. 94,291 miles) on a Texas expressway at highway speed during rush hour, I experienced a sudden and significant loss of engine power. There were no warning lights, no safety system activation, and no advance indication of the failure. The vehicle decelerated abruptly with traffic behind it. Live OBD-II data was being logged during the drive and was provided to the service advisor at the authorized Subaru retailer. This incident occurred only 3 days and approximately 125 miles after the vehicle was returned following a major engine repair performed at an authorized Subaru retailer in Texas under active powertrain warranty. That repair was supervised by a Subaru of America District Quality Manager and Field Technical Specialist, who conducted a 110-mile validation drive prior to release. Prior to the highway failure, visible fluid leaks were documented across the intake ducting, residue on lower engine components, a sweet and burning odor after driving, and milky sludge returning to the coolant reservoir — all within 125 miles of pickup. These are consistent with ongoing oil and coolant cross-contamination, which was the original diagnosis documented in the dealership's digital service portal. The vehicle has now undergone three major engine teardowns since March 17, 2026 — over 100 days out of service — for the same underlying powertrain issue on the FA24 engine. The current repair involves cylinder heads sent to a thi

I am submitting this complaint regarding a 2021 Subaru Ascent that I purchased new from Herb Gordon Subaru in Maryland. The incident occurred while driving on I-95 at approximately 75 mph with my family, including children, in the vehicle. The vehicle experienced a sudden and complete powertrain failure without any prior warning indicators. This created an immediate and serious safety risk on a busy highway. Fortunately, we were able to safely maneuver the vehicle out of traffic and avoid a collision. Prior to this incident, the vehicle had undergone regular maintenance, and there were no indications of any imminent powertrain failure. While a routine fluid service had been recommended, it was not presented as urgent and was planned to be completed at a later time. Following the incident, I conducted further research and learned that the vehicle had previously been subject to a manufacturer recall involving engine harness/ECM-related issues, which had been completed prior to the sale. This material information was not disclosed to me at the time of purchase and only came to my attention after the failure occurred. Had I been informed of this recall history at the time of purchase, it would have reasonably influenced my decision-making, and I would have reconsidered or sought further clarification before proceeding. The estimated repair cost is approximately $11,000. Subaru of America has offered $2,000 in goodwill assistance, which I consider inadequate given the severity of

I had catastrophic transmission failure. The car was completely inoperable. Thankfully this only happened in a parking lot. If this were yo happen while merging into traffic it could have been very dangerous. This was the second cvt in this vehicle. The 1st transmission was replaced around 52kmiles. The second transmission lasted not even 13 months sndless than 15k miles. Subaru replaced the transmission for a 3rd time at a cost of 1k to me. I no longer have the car.

Issue 1: Complete transmission failure was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles (drive train warranty 5 yrs/60,000 miles). Had to purchase and have installed a rebuilt Subaru transmission. First noticed transmission was slipping with a large load in vehicle May 2025 at 4 years and 8 months after purchase at about 40,000 miles on odometer. The issue was subsequently not noticed under typical load until slipping transmission signs reappeared December 2025. Made appointment in March 2026 due to a planned trip to [XXX] mid-February to mid-March. Failed transmission poses critical safety risks including loss of acceleration, stalling in traffic and unexpected deceleration. Subaru of New England was able to install the transmission at about 50% of the initial estimate over $12,000 (final paid $5400). Subaru of America file was claimed (Case # XXX-XXX) for the balance, but any further reimbursement was rejected. Issue 2: Driver window alternating between getting stuck fully opened as well as reversing to the open position when trying to roll up. The failure of window regulator and channel run was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles. Had to purchase and replace the Subaru window regulator and channel run. Power window failures in the open position create significant safety risks including vehicle theft, interior dam

I am a CPST. I use the Joie Mint Latch with my own child. On multiple occasions I have found on multiple occasions that when securing the lower rigid latch it will flip to green (secure) when it is not actually latched. It is during install when "jiggling" it into position. I am concerned parents who arent as well educated on car seats may not double check the latch before traveling and their child may not be safe.

Seat Belts

2021 Subaru Ascent (VIN#***). Water found dripping down both second row seatbelts on multiple occasions during or following heavy rain, accumulated into mold growth on the carpet in front of second row seats to the front of the 3rd row seats (cargo area dry, front footwells dry). Authorized Subaru dealer technician report (dated 10/29/25 and 12/3/25 copy pasted into email) explicitly documents 'condensation build up on the interior of roof (seat belt area)' due to unlocated water intrusion. The dealer attributes this to 'leaf debris' in the front cowl area and rear hatch hinge despite the leak occurring at the rear C-pillar (and notably cargo area and front footwells showed no moisture making this physically impossible). Despite confirmed moisture exposure to critical passive restraint systems, the dealer relays that the manufacturer has issued a verbal-only warranty denial (stating no addl records exist aside from the initial technician report) and suggest the only repair be carpet replacement, with refusal of confirmation of the source of the leak and no proposal of replacing the 2nd-row seatbelt retractors nor provide a written safety guarantee. The vehicle is covered by an active 8yr/120,000-mile Subaru Gold Plus Added Security Plan (Agreement #*******, started on 8/2/21), yet the manufacturer is refusing to honor the contract for the defect or the resulting biohazard ('mold spouts' documented by their technicians on carpeting and into the foam).

While driving my Subaru Ascent, a check engine warning light appeared on the dashboard. Shortly afterward, I noticed smoke coming from the engine compartment. I immediately pulled over and turned the vehicle off. Within moments, flames began coming from under the hood. The fire spread rapidly, and within 5-10 minutes the entire vehicle was fully engulfed in flames. The fire originated from the engine compartment. The vehicle was a total loss. Subaru of America was notified on 12/23/2025, but no follow-up or update on investigation has been responded. The vehicle was always serviced with Subaru. This sudden, traumatizing and catastrophic failure with no prior warning.

The transmission on our 2021 Subaru Ascent is slipping and failing to accelerate, RPMs reving, and every issue indicator notification light is on. We took the car to our mechanic, then to the Subaru dealership service dept for diagnosis. A full transmission replacement is required plus associated repairs for a cost of $14,543.98. Service estimate attached. This repair is more than 2/3 of the value of the vehicle. This make/model and transmission type have documented problems and Subaru has previously issued an extended warranty on other model years for this same transmission issue. We are trying to communicate with the Subaru customer service but have had limited response due to the holidays and have not had a resolution yet in the past month.

I bought a 2021 Ascent - Touring , lately there was an ever increasing amount of wind noise. It sounded like it was coming from the sunroof, but I couldn't see anything from the inside that looked out of place and there were no signs of water leaking. I finally looked up on the roof from the outside and the weather stripping along the back of the sunroof was coming out. The glue is thin, and didn't even stick to it anymore.. This is an ongoing issue. There are people people on the Subaru Ascent, Facebook Reddit forms that have said they are having the same issue..

The transmission/CVT component on the vehicle, 2021 Subaru Ascent is malfunctioning. When being driven, the malfunctioning transmission will cause the vehicle to hesitate in traffic, as well as feeling the slippage of the transmission when in motion. The vehicle also has a burning odor when being driven. NYS inspection was conducted on 10/27/25. The transmission malfunction has been confirmed by a Subaru dealer, who has had the vehicle at their dealership since 11/5/25, 34 days as of today. Subaru Advocacy , whom I have had many calls and emails with, is unwilling to replace the transmission at their cost.

On Friday, June 13, 2025, while (thankfully) in my driveway, the transmission broke on my 2021 Subaru Ascent in my driveway. I simply started my car, put it in reverse, and my car jerked and stopped. NO prior warning. I was on a slight slope. I thank my lucky stars I did not have my kids out on the road when it happened. I had to have it towed to the closest Subaru dealership (a $395 charge). Upon inspection, my transmission (the CVT model) was no longer working. My car was bought in December 2021 and it has around 80,000 miles on it. In researching, I saw that the 2019 and 2020 models with the CVT had been recalled (or had their warranties extended to 100,000 miles coverage) for the EXACT thing that happened to my car. If I am correct, my car was manufactured in November of 2020 from what I was told. I find it so hard to imagine that a transmission should fail due to "no reason" at this point, my car is not even 5 years old! The fact that this has happened on cars right in the timeframe of when mine was made, it's hard to imagine I should have to pay almost $10,000 for a new transmission when the history of these transmissions failing have been quite newsworthy! It was not fixable, the only choice I was given was to buy a new transmission. In today's economy, I just find this unacceptable.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
