2020 SUBARU CROSSTREK

SEATS

The bolt attaching the front left corner of the seat to the rails came loose and allows the seat to wobble and bounce.

POWER TRAIN

The rear differential on my Subaru Crosstrek Hybrid has failed twice. The first failure occurred around 12,000 miles and the second around 50,000 miles, both while maneuvering slowly in a parking lot. There were no warning lights or messages beforehand. The failure caused grinding and drivetrain resistance while turning. During the second incident, a certified Subaru dealer confirmed the rear differential had failed again. They also discovered that Subaru had issued a revised version of the differential that is no longer compatible with the original axles, requiring additional parts to complete the repair. I was informed the original design has been discontinued, suggesting Subaru was aware of an issue. This kind of drivetrain failure is a significant safety risk, especially if it were to occur at higher speeds or in traffic. The issue has now occurred twice on my vehicle under normal driving conditions, and was verified both times by a 2 Subaru dealerships in Southern California. When I returned to pick up my vehicle, I was told by the service technician that another hybrid Crosstrek had just come in for the exact same failure. Additionally, a local independent Subaru performance shop mentioned they have performed three similar rear differential replacements this year. This clearly appears to be a recurring problem, potentially linked to a design flaw, and I believe it warrants further investigation.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

The 2019-2021 Crosstrek Hybrid has an issue with the fuel tank design. Subaru has finally released a TSB (Reference: 09-82-23R) that explains the issue in more detail and how the defective parts need to be replaced. In short, the fuel tank has a design flaw such that regular fuel corrodes the fuel tank and causes clogging in the vapor vent tubes. Subaru says it's related to fuel with high ethanol content, however I have been filling up with regular fuel and have still experienced the issue. I have personally owned two of these vehicles and experienced the occasional P0452 check engine light which when diagnosed by a licensed shop pointed to this fuel evap system issue. Subaru has finally acknowledged that this is a known issue and issued the TSB, however they have not yet issued a recall. The repairs for this issue are expensive and the symptoms are an occasional check engine light. I am concerned because this issue is not easily detectable and is expensive to repair. Since this involves the fuel tank and fuel vapors tubes I am concerned there might be a fire risk or health risk, but since there is no recall issued I don't know if it can be ignored or needs immediate attention. Subaru does cover this repair under 3 yr / 30k mile warranty but with the irregular symptoms it is hard to detect and diagnose it and Subaru only issued the TSB in Jan 2024 when the 2021 model became 3 years old and out of warranty. It seems like Subaru knew about the issue but didn't want to address it under warranty so they issued the TSB only after all the cars were out of warranty and only now when the consumers have to pay out of pocket are they diagnosing it correctly. Also, this issue triggers the check-engine light only occasionally and at random, and when the light goes on all the vehicle safety aids like pre-collision braking and rear cross traffic warnings are disabled. I think this is dangerous because drivers tend to get used to having those features.

VEHICLE SPEED CONTROL

The contact owns a 2020 Subaru Crosstrek. The contact stated while pulling into a parking spot and depressing the brake pedal to come to a complete stop, the vehicle failed to respond. The contact stated that upon depressing the brake pedal a second time, the vehicle jerked, unintendedly accelerated, drove up the curb, and crashed into the metal plastic pole of Wawa. The pole was fractured. The air bags did not deploy. There was no injury sustained. There was no warning light illuminated. A police report was filed, but the contact did not have the police report information available. The vehicle was towed to the residence. The dealer was notified of the failure and informed the contact that they could only diagnose the vehicle after it had been repaired by an auto body repair shop. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and advised the contact that she would be contacted later and would be informed of the location she would need to take the vehicle for diagnostic testing. The failure mileage was approximately 42,000.

What component of system failed: transmission At low speeds, my car makes a low moaning sound. I took it to the subaru dealership and after 2.5 hours, they said it's an issue with the transmission and needs a full replacement. Safety: According to a local subaru dealer's website, "While it might be tempting to keep driving despite a known transmission fault, especially if the car seems to be running ‘fine’, there are inherent risks. Firstly, there’s the potential for the fault to escalate, causing more significant damage to the transmission system. This could, in turn, result in costlier repairs down the line. Secondly, and more crucially, a transmission fault could lead to unpredictable vehicle behavior, especially when changing gears. This unpredictability can be hazardous, not just for the driver but for others on the road as well."
