2018 Subaru Crosstrek engine problems

Filed Jul 7, 2026 · Electrical, Engine · CO

On 06/26/26, while traveling at highway speeds, the vehicle suffered a sudden, catastrophic loss of motive power in active traffic due to a blown out/melted Cylinder 4 ignition coil. This unexpected engine failure forced raw fuel into the exhaust system, causing an immediate internal thermal meltdown of the catalytic converter, rendering the vehicle entirely undriveable and creating a severe highway safety hazard. This vehicle was previously serviced under the federal safety agency Campaign 21V264000 (Subaru Recall WRE-21), which was intended to permanently remedy an ECM software defect that over-energizes and melts the ignition coils. Subaru of America (Case # 260630-2101598) is denying coverage, claiming that because the recall was executed 90,000 miles/5 years ago, and because the current software Calibration ID (CID) matches their post-recall database, the thermal melting is standard "wear and tear." I am filing this complaint because a safety recall remedy must be permanent and effective. The physical evidence, a melted plastic coil housing with a hole blown through it, is an engineering impossibility under normal wear and tear and proves that the original software patch failed to permanently mitigate the high-voltage overloading defect. Over a 5-year period of gradual thermal degradation, the defect reoccurred, creating the exact highway hazard the recall was mandated to prevent. I request a federal investigation into the long-term efficacy and failure rates of the WRE-21 software reflash.

Dangerous stall in traffic due to ignition coil failure. Ignition coils and spark plugs were replaced during the WRE21 recall campaign only 13k miles ago back in 2021. Stopped at red light awaiting to turn left when the vehicle started shaking violently. No check engine light came on though. When the light turned green, the vehicle was barely able to move forward then it completely stalled before pulling over to the curb. Since the tail of the car was sticking out into traffic a bit, it was a downright dangerous situation. Car had to be towed to dealership and took them 5 days to diagnose and fix the problem. Ignition coil and spark plug replacements costed $1500. Don't think the recall fixed the root problem and this could potentially happen again.

I have a 2018 Subaru Crosstrek, I am the second owner, the first owner bought it in 2019, I am having acceleration problems, I have already taken it to two different mechanics, they say it is a problem with the computer, they have already checked and scanned it and they tell me that you have to reprogram the ECM for DTC P1603 / Engine idle drop or stall, when the car accelerates it makes a jerky or knocking noise when I go 15 miles or stop and move forward again the car locks, this only happens when the car is already warm and has been used for about 10 minutes

I was driving on Tuesday, January 17 and my steering made a pooping nose strug and swirl to the right then continue driving. I found it strange but this never happened. Then on Thursday, January 19, 2023, I put my vehicle into the driveway, my engine was not even off yet, my steering wheel to the left with key still in the ignition it locked. I know how to unlock my wheel but with this I can't this is the 4th time it has happened. It is freaking me out because every time my son is in the car. If this happens when I am driving it going to take the grace of God to save us. The first time was in Hartsdale, NY parking lot Subaru assistance was called, he made a report, 2nd time it happened by Trader Joes Larchmont, NY Police came out they made a report, 3rd time a Man in KeyFood Bronx, NY 2022,help me and 4th Time January 19, 2023 Entourage Automotive Corp tow was called. He wants to tow my car in the morning to Subaru Service because he says it too stiff and hard to turn. He had to lean his body on it and then turn it hard. I can't do that and it not suppose to do that. In December 21, 2022, my car was park under the port, when I went out the hand rest was wrinkled. When I took my car in for 4 tires I indicated this to Will the service guy and he said I could buy a new one and have it replace. It was strange he never hard of it. Well know through some research this is a big issue with vehciles from 2017 to 2022 and they have a cover for it now. but it should have been a recall to fix the ones it already happen too now.https://subaru.oemdtc.com/3574/2017-2021-subaru-center-console-armrest-cover-wrinkled-appearance My car is staining from the ceiling to the side of the upper doors, as well as water stains.

When I attempted to start the car, the starter would spin but fail to engage the flywheel, leaving me stranded in a parking lot. The car needed to be towed to a repair shop. The repair shop confirmed the problem and replaced the starter with an OEM replacement part. I am told that the manufacturer has redesigned the part. The car has less than 55,000 miles on it. I was unaware of any symptoms of the impending failure of this engine component.

This morning August 29 2022 I started my 2018 Subaru Crosstrek, when I put it in gear the car just took off before I could stop it. The idle when about 5000 RPM and then up and down. I was able to get the vehicle stopped and parked. I tried starting the vehicle again and the same. The vehicle is on its way to Crews Subaru North Charleston. Even the tow truck driver wouldn't drive the vehicle. This makes the vehicle unsafe. What if someone was walking past my driveway when this happen? It took about 40 feet to get the car stopped with my foot on the brake hard and to park the car. I have a video showing the RPM at 3900 but could upload it to your site. The consumer stated he would like the complaint removed, the floor mat holding the accelerator down was the problem.
