2022 Subaru Outback

In September 2026, after a jump start, my vehicle's battery emitted a strong sulfur/rotten-egg odor, indicating overheating and overcharging. I was advised to shut it off immediately. The vehicle is now undrivable and parked, and I am concerned it presents a fire risk. This is the latest failure of a chronic electrical defect documented in the dealer's own repair orders since early ownership: •⁠ ⁠March 16, 2023 (4,985 mi): vehicle needed a jump start. Dealer tested the battery, said it passed, and blamed my driving habits. •⁠ ⁠May 16, 2023 (5,503 mi): vehicle again needed a boost. Battery failed the dealer's test and was replaced under warranty; dealer cited Subaru bulletin 07-213-22R. •⁠ ⁠August 4-8, 2025 (15,188 mi): vehicle again needed a boost. Battery failed the dealer's DCA8000 test (low CCA) and was replaced a second time. A dark-current draw test found the Telematics Data Communication Module (DCM) causing a parasitic draw (code B2A0C); the DCM was replaced. When I arrived to collect the vehicle after being told it was repaired, it would not start in the dealer's own shop. Subaru paid for the DCM repair as one-time goodwill while stating it was not covered by warranty. These repair orders understate the frequency: throughout ownership the vehicle needed a jump start roughly 80-90% of the times I used it, even the day after being driven, and I used roadside assistance several times. I believe this matches the known parasitic battery drain defect on 2021-2022 Subaru vehicles (control modules, including the DCM, failing to enter low-power sleep mode), the subject of pending class action litigation (Taylor v. Subaru of America, No. 2:26-cv-4935) and Subaru technical service bulletins. My dealer replaced the implicated module, the problem recurred, and the vehicle has now had an overcharging event that left it undrivable.

During normal vehicle operation, the castle nut came off the control arm causing it to disengage from the wheel. It is currently with the dealer for inspection and service. They still have not confirmed if this and the associated damage will be covered under the extended warranty. I have also reached out to Subaru of America as this is a safety concern and is same as the recall on the 2023 model.

My 2022 Subaru Outback Premium has had repeated intermittent stall/no-start events. The exact failed component is UNKNOWN, but the issue appears related to the fuel system, engine control, electrical system, or heat-related sensor/relay failure. The vehicle is available for inspection upon request. The first event occurred while parked: the engine shut off/would not start, while the dashboard and screen remained powered. After about 30 minutes, it started again. A later event occurred while driving: the engine suddenly shut off, but the dashboard and infotainment screen stayed on. I could not restart the engine for about 10 minutes. When it restarted, the vehicle would not accelerate past about 30 mph, suggesting reduced-power/limp mode. This created a serious safety risk because the vehicle lost motive power while in traffic. The vehicle was taken to a Subaru dealership. The dealer diagnosed the high-pressure fuel pump as failing and replaced it under the powertrain warranty. About one month later, the same issue occurred again while parked: the vehicle shut off, all dashboard warning lights illuminated, and it took several minutes before it would restart. The dealer then stated the battery was weak and replaced the battery. The new battery tested good after replacement. One week later, the issue returned again. A consistent pattern is that the problem occurs when it is hot outside and the vehicle has been running for more than one hour. The vehicle has been inspected by a Subaru dealership multiple times. The problem has not been reliably reproduced by the dealer, but the dealer previously confirmed a failing high-pressure fuel pump and later a weak battery. Warning lamps appeared at the time of failure, including multiple dashboard lights/check engine-type warnings after the engine shut off. There were no consistent warning messages before the stall/no-start events.

I am submitting a complaint regarding the battery in my 2022 Subaru Outback. The original battery failed after only approximately 2½ years of normal use. This issue became a serious safety concern when my vehicle stopped at a traffic light at a very busy intersection and died. I was unable to safely move the vehicle and felt that I was in a dangerous situation because of the surrounding traffic. I was so concerned for my safety that I had to call 911 for assistance. After experiencing battery problems, it was determined that my Subaru Outback needed a larger, higher-capacity battery. This raises concerns that the original battery supplied with the vehicle may not have been adequate for the vehicle’s electrical demands. I do not believe a vehicle of this age should experience a battery-related failure that leaves the driver stranded in an active intersection and creates a potentially dangerous situation. I am requesting that Subaru issue a recall On model year 2022 Subaru Outback. Im requesting a reimburse for the costs I incurred as a result of replacing the original battery. Most importantly, I believe Subaru should address whether this battery issue presents a safety risk to other Subaru Outback owners, since a sudden loss of vehicle operation in traffic could potentially result in a serious accident. Unfortunately, the problem did not end there. Roughly a year and a half after the replacement battery was installed, I had to replace the battery again. Having multiple batteries fail within such a relatively short period of time makes me concerned that there may be an underlying issue with the vehicle’s electrical or charging system rather than simply a problem with the batteries themselves Thank you for your time

When traveling eat 6-65 mph and needing to merge and stepping on the gas pedal all the way the car would just sit there and do nothing for 1-2 seconds. this was not a one off situation. The car would do this regularly until I found out subaru had a fix for the transmission software. I recently had to pay to have this done even though my car was still within the powertrain warranty because Subaru said it is maintenance .

Vehicle is exhibiting signs of a possible design defect which causes windshields to prematurely crack, break, or shatter. My vehicle is a 22 Subaru Outback that when bought new, in the first week of ownership developed a windshield crack that the dealer ship refused to replace under warranty. We worked a deal out and were responsible for a percentage of the repair on our part, and they replaced the windshield. The 2nd Windshield cracked after a few months, no visible impact this incident either. We had it replaced, and this would be our 3rd windshield (we tried another brand of glass called FUYAO). Now this 3rd windshield suddenly cracked again, without a sign of impact. vehicle has about 38,000 miles and considering the driving conditions and care the vehicle experiences, i believe it to be some sort of design defect which will crack any new windshield within several months.

The contact owns a 2022 Subaru Outback. The contact stated that while driving at an undisclosed speed and making a left turn, the message "EyeSight Disabling" was displayed. No warning light was illuminated. The vehicle then lost motive power and was unable to restart. The contact called 911, and two bystanders assisted in pushing the vehicle to a Jiffy Lube. The vehicle was towed to the dealer, who determined that the battery had failed and needed to be replaced. The vehicle was not repaired. Upon research, the contact associated the failure with the engine. The manufacturer was made aware of the failure. The failure mileage was approximately 58,000.

I parked my 22 Subaru Outback in my enclosed garage about 11:00 AM. I was in and out of the garage at least five times between 11:00 AM and 6:00 PM and in a room next to the garage the rest of the time. At 6:00 PM I went into my backyard. Upon returning inside the house about 7:30 PM I heard the car running in the garage. The car had remotely started sometime between 6:00-7:30.The keys had been hanging up all day and were not touched. My phone had been placed on a shelf and was also untouched between 6:00-7:30. There was no explanation for why the car started in the garage. Fortunately it wasn't while we were asleep. We took the car to the dealer the next day and were told it was impossible for the car to start under the conditions described above and there was nothing wrong with the car. Although we never had issues with the car previously We drove it from that dealer to another dealer down the road and traded the Subaru for another car so we no longer own it. I just wanted to report it in the event this is not an isolated incident.
