2020 Subaru Crosstrek

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.

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."

6-8in windshield crack on passenger side, near the bottom just above defrost vents. No apparent trauma to the windshield in that area. No indication that there was a crack forming otherwise; appeared seemingly overnight. Have not yet reported to insurance, dealer, or mfg. I have seen that there was a class action settled recently regarding some Subaru windshields cracking without warning so this may be a known issue. Car is available for inspection upon request.

The contact's significant other owns a 2020 Subaru Crosstrek. The contact stated while his significant other was driving from a complete stop, several unknown warning lights illuminated. The contact stated that the failure had been recurring. The vehicle was taken to the dealer several times. The dealer replaced the battery, the fuel cap, and cleared the warning lights; however, the failure persisted. The vehicle was towed to the dealer, where it was being diagnosed. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 51,000.

The auto engine shut off was disengaged by the dealer while doing some repair. When we picked up the car, noticed engine trouble icons signifying this. We called the dealer and advised of this situation. We had asked if it could be disconnected and was told no, it is forbidden and a safety issue. So when I advised it was turned off, the dealer then refused to work on the car any further or to turn it back on. THEY ARE THE ONLY LOCAL SUBARU DEALER IN KNOXVILLE. That certified mechanic is the one who DID NOT reconnect this safety feature and then refused to fix it. What ever measures need to be taken to this dealer (Grayson Subaru - Knoxville) I need to do so. This has created a huge safety issue with the car and driving and a authorized / approved Subaru dealer refuses to follow the law.

This vehicle is a plug-in-hybrid. It should not be able to move while plugged in. Problem is attempting to move the vehicle when the charge cable is still attached and the vehicle is on an incline. Subaru does not display a warning message - instead it displays "check engine" and an ambiguous symbol (a red steering wheel). Subaru disables the power to wheels that would have enabled the driver to close the gap to the charging station. Instead the vehicle rolls away from the charging station, breaking power plug at the vehicle port. Even placing the car in Park does not prevent damage, the car will roll down hill until the Parking gear latches. I have now broken my power plug 3 times. I am a professional electrical engineer. This should not be able to happen Subaru should prevent the car from being able to move if the cable is still attached, and instead display a message that the cable is still attached. With the "check engine" message, I engaged my OBD diagnostics and it could not find a "check engine" flag. At this point, I put the car in gear, and even through Subaru disables power, the car then passively rolls down the driveway, breaking the cable at the power port. Instead of the ambiguous "red steering wheel" icon - Subaru needs to lock the car in Park and display a real message. When you finally turn the ignition off - Subaru displays a huge "Goodbye" message on the auxiliary display. I say finally because if you do restart the ignition with the cable attatched - you will not be able to turn off the ignition - only after exiting the vehicle, disconnecting the plug will you be able to turn off the vehicle. Not being able to turn off the ignition should not be permitted. Numerous errors in the control logic.

The contact owns a 2020 Subaru Crosstrek. The contact stated that while she was sitting in the parked vehicle on the side of the road, another vehicle driving at approximately 60-65 MPH rear-ended her vehicle. The contact's vehicle was pushed into the highway's first lane. The front driver's side seat belt failed to restrain the contact in her seat, causing her forehead to hit the steering wheel and the back of her head to roll between the A-Pillar of the front windshield and the front driver's side door. The contact attempted to depress the brake pedal when the front of her ankles hit the bottom of the dashboard. The air bags did not deploy. A police report was filed. The contact was transported by ambulance to the hospital and received medical attention for a brain injury, lower back pain, and broken blood vessels on her ankles. The contact was later diagnosed with craniocervical instability (CCI). The vehicle was towed to a body shop, where it was repaired. The vehicle was not deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was unknown.
