NHTSA owner complaint records remain part of Official Vehicle Data. Subjective review contributions remain in Owner Experience. One does not validate or prove the other. Read the methodology.

EVIDENCE, NOT A SCORE

WHAT THIS DATA CAN TELL YOU ABOUT RELIABILITY

Official records can provide useful research context, but each source has a different meaning. Complaint counts are not failure rates; recalls are formal safety campaigns; manufacturer communications are technical or service documentation; and investigations reflect formal NHTSA activity. Data Confidence measures evidence availability, not vehicle quality. CarIQ does not publish a composite Reliability Score.

Available evidence summary: 296 NHTSA owner complaint records; 4 safety recall campaigns; 0 manufacturer communications; 0 applicable NHTSA defect investigations.

Owner-submitted NHTSA complaint · ODI 11759871
Read complaint narrative

Vehicle's Auto Start-Stop system shut the engine off while stopped at a red light in [XXX], in rainy conditions in late XXX at approximately 29,000 miles. When the brake was released after the light turned green, the engine did not restart, leaving it stopped in the travel lane in live traffic. The driver had to use a portable jump starter to get it running again. This was not isolated — repeated failure-to-start incidents in prior weeks had already prompted carrying a portable jump starter in the vehicle. At the time we believed this was a failing 12V battery. The original battery was replaced XXX with a new aftermarket AGM battery. Despite that replacement, the vehicle has continued to have multiple complete battery drain if left parked for multiple days (but less than a week), indicating the restart failures were likely caused by an underlying parasitic electrical draw rather than a simple worn-out battery. Subaru's own Technical Service Bulletin 07-199-21R, "Measurement of Dark Current (Standby Current Draw)," describes this exact failure pattern (batteries/vehicles going dead over time due to standby current traced to the VDC module and/or Power Rear Gate control module) for this model and model-year range. A pending federal class-action lawsuit, [XXX] v. Subaru of America, Inc., Case No. XXX (D.N.J., filed XXX), alleges an electrical-system defect preventing one or more control modules from entering a proper low-power sleep state, causing parasitic battery drain, and specifically names 2021-2022 Outback vehicles. We are concerned this defect can cause the Auto Start-Stop system to fail to restart the engine at a stop in live traffic, creating a real risk of being rear-ended or blocking an intersection, as happened in the incident described above.

Good Day! I bought my 2021 Subaru Outback XT Onyx in Jan 2021. I had waiting 6 yrs for Subaru to use the Turbo Motor in the Outback again. I've had this car for 5 years with my warranty running out Jan 2026, but I only drive 5000-7000 miles per/yr. Current odometer is 29,901 miles. At my most recent oil change service at the Dealer, they showed me a video of my cars drivetrain from underneath. There were two bad seal leaks. One at the transmission pump housing and the other at the Upper Oil Pan. I had been there for an oil change a year earlier for the same service and there was no mention of these issues! After speaking with the service advisor, he said to call Subaru Customer Advocates. They listened to my situation and a few days later offered a $1400 credit for a $4000 job that involves the removal of my cars engine (upper oil pan) to replace it because it's bolted to the frame there. The other leak seal involves dropping the transmission. These are major repairs that following will dampen my ownership experience after decades of Subaru praise by Americans. I researched this issue online and found out there was a manufacturing defective regarding the silicone liquid seals they used for 2020-2022 Outback, Ascent, & WRX! This procedure was used throughout the driveline with the Turbo Motor & CTV Trans. There are 1000s of accounts of this defect placing burden on the owners of these cars who bought them in good faith. I did the research, called the dealer & Subaru with the discovery & overall complaint! I asked for 80% to 100% help with these repairs because how many more will I have to deal with after these two are repaired??? I have received zero responses from either after expressing that this was a known defect, Bullitens went to all the dealers, nothing was mentioned to the owners, and they've just covered those cars still under warranty. Since I didn't drive enough, the seal issues on my car took longer to start leaking, and then out of warranty. HELP!

I am reporting a serious and intermittent steering safety issue with my 2021 Subaru Outback. On two separate occasions, the vehicle suddenly lost what appeared to be power-steering assistance while the vehicle was in motion, causing the steering wheel to become extremely difficult to turn. The first incident occurred while I was driving on the highway and going down a ramp. The steering suddenly became extremely difficult to operate and a warning symbol illuminated on the dashboard. I was able to maintain enough control of the vehicle to safely pull over to the side of the road. I turned the vehicle off and restarted it, and the warning light disappeared and normal steering operation returned. The second incident occurred while I was making a turn into a neighbor. The same problem occurred: the steering suddenly became extremely difficult to turn and a warning light appeared on the dashboard. After turning the vehicle off and restarting it, the steering returned to normal. The intermittent nature of this problem is concerning because restarting the vehicle temporarily restores normal steering, but the failure has now occurred more than once without warning. One of the incidents occurred while traveling on the highway, creating a significant risk of loss of vehicle control and a collision. I am concerned that this may involve the vehicle’s electric power-steering system or related electrical components. I am reporting this to NHTSA because a sudden loss of steering assistance while a vehicle is moving presents a serious safety risk, particularly while turning or traveling at highway speeds. I am requesting that NHTSA document this complaint and evaluate whether similar steering failures have been reported by other owners of 2021 Subaru Outback vehicles.

My 2021 Subaru Outback suffered a failure of the Oil Control Valve (OCV), a sealed Subaru component with no maintenance interval, no inspection procedure, and no preventative service. This failure allowed engine oil to migrate into multiple wiring harnesses and modules, causing extensive electrical contamination. This is not normal wear and tear. It is a latent defect in a Subaru component. Due to the failure of this sealed component the Subaru dealership and a second independant shop have recommended replacing the entire electrical wiring harness at over and estimated $15,000. Even if the entire harness is repalaced the extensive contamination may find its way into electrical connectors even after replacement of the harness. The fact that this contamination was so wide spread, and there were absolutly no warnings that indicated the widespread contamination is alarming. I guess the thought is that different electrical components could just stop working. This seems like a serious safety concern. It is impossible to know how long the contamination was spreading through the car since there are no errors or warnings that indicated an issue.

I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property Damage occured. No injuries. Vehicle defect.

First battery drain in car. Bought a new battery and it drained again for the second time. Called Suburu to ask about a parasitic drain from the DCM and they said it was likely that and told me to call Suburu America. Did that but they wanted me to take it to a Suburu dealer to get the problem verified. I don’t have the $ to do that. I notice there is a class action in court right now for this exact problem.

We are VERY concerned about the failure of some very important safety features of our 2021 Subaru Outback Touring Edition. We were involved in a bad car accident caused by a person under the influence who was in handcuffs when we were taken away by ambulance. As you can see by the photos, there was MAJOR damage to the other car and significant damage to ours. What is most concerning is the fact that NONE of the airbags deployed and the safety and security plan also failed - it did not call 911. I had to find my phone on the floorboard and call 911 myself. I am not sure if the insurance company will call it a total loss but I really don't think I want the car back BECAUSE of the failures of these very important safety features. I truly feel like Subaru has some explaining to do on this.

NHTSA complaints are reports submitted by vehicle owners and other consumers. Complaint counts do not represent the percentage of vehicles affected and do not by themselves establish that a safety defect exists.

A higher complaint count can partly reflect how many vehicles were sold, vehicle age, and other factors. CarIQ does not yet normalize complaint counts by vehicles sold.
