2018 Subaru Crosstrek Complaints

ELECTRICAL SYSTEM,ENGINE — Filed 06/26/2026

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 NHTSA 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.

Drove home parked next day 3/19/2026 turned on car made a tapping nouse after five minutes went away call dealer left message on Andrew manager answering service. Car parked at work 8 15 am to 3 40 pm. Drove home got home at 3 50 am turned off heat heart rushing water like down a creak. Turned off car looked in the front some liquid gushing out car smelled like it was burning. Put paper under car with rock to see color of fluid it was blue new it was coolant call dealer againt went to voice mail manager Andrew hung up went to dealer. Arrived at 4 40 pm Chris service Advisor check said was not save to drive burning smell still there got another loaner another 200 dollar on top of the 250. Called saburu customer advocacy this morning spoke to Latoya 11 15 am 3/20/2026 case number XXX-XXX waiting for someone to call me by Tuesday. I requested a 3 year gold plus warranty as a goodwill gesture to restore my confidence in the vehicle and protect my engine integrity. I am deeply concerned that the gushing coolent damaged the internal engines seals or may have been compromised due to the heat, the hoses or gadgets now or over time. I have puctures and documents that the system won't allow download. If the car continues to have reoccurring issues due to this complete repair failure. I am asking them to replace my 2018 saburu crosstrex that has only 52, 315 miles with an equal value car without issues. My car is 10 years old low mileage.

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.

SUSPENSION — Filed 02/01/2026

Starting at around 75,000 mileage on my 2018 Subaru Crosstrek, a persistent howling noise is heard while driving. This noise comes from the rear of the vehicle and occurs at nearly all driving speeds, measuring at around 90.0dB while on a highway (a dangerous level for prolonged exposure). A service shop and the dealership have both diagnosed the noise as an issue with the rear wheel bearings (consistent with Subaru Service Bulletin 05-70-19R). In January 2026, my low tire pressure warning light appeared on my dashboard. I checked the tire pressure with a gauge and found no issue. I assumed (and later confirmed while getting a tire changed) that the tire pressure sensor had a dead battery, and that the warning light was related to this dead sensor rather than an issue with the tire pressure. Before getting the sensors replaced, I drove for a week with the low tire pressure warning light on my dashboard. I ignored this sensor because I confirmed daily with a pressure gauge that the tire pressure was fine. However, one day while driving in February 2026, I got a flat tire on the front passenger side. I drove with this flat tire for at least six miles, not knowing I had a flat. The howling noise from the rear wheel bearings masked the noise from the flat tire, and I could not audibly distinguish anything out of the ordinary with my car. Unfortunately, this occurred in the same period of time that my tire pressure warning light was giving false flags for low tire pressure. I feel it important to log this issue because - had my rear wheel bearings not been making a howling noise - I would have noticed the flat tire immediately and would not have posed a safety risk to myself or other vehicles.

EXTERIOR LIGHTING — Filed 02/26/2026

The contact owns a 2018 Subaru Crosstrek. The contact stated that while driving at an undisclosed speed, the headlight warning light illuminated, and the contact noticed that the passenger's side LED headlight had become inoperable. The vehicle was taken to an independent mechanic, where a headlight assembly replacement was recommended. The vehicle was not yet repaired. The manufacturer was not contacted. The failure mileage was approximately 90,000.

POWER TRAIN — Filed 01/28/2026

Vehicle was maintained by dealer and out of the blue, started bucking intermittently while driving resulting in an unsafe driving experience. took it to the dealer to evaluate, told us, "They could change the transmission fluid and filter to see if that fixes the problem." they were not sure that would fix the issue. After researching issue, saw there were numerous complaints about the transmission in the 2018 crosstreks. Call a professional transmission shop and will be making an appointment with them in the near future. They told me (and I found out through my own research) if is was the transmission filter and fluid, it would act up all the time, not just intermittently. And... the dealer wanted to charge me $665 to change the filter/fluid and not sure it would fix the problem, seriously? so now I have to wait and see what the transmission shop says. I have also seen post about the ignition box also gives issues, so who knows, maybe it is the ignition cutting out causing it to "buck" every here and there. Either way, the vehicle is unsafe to drive and could potentially cause a major accident if the transmission locks up or the ignition totally cuts out. Should be a recall either way and Subaru should be responsible for it. This is nothing we have done that could've prevented this issue.

The front windshield spontaneously developed a crack about 5 inches long which later suddenly increased to about 15 inches in length. It is our understanding that this problem has occurred in the windshields of other Subaru models. The internet states that Subaru windshields have had a tendency to crack without impact due to the windshield's angle or thinness to accommodate Eyesight technology.

All four tire pressure monitoring sensors failed on my 2018 Subaru Crosstrek at approximately 69,000 miles. The TPMS light remains illuminated, and the system no longer provides low-tire-pressure warnings. Subaru of America acknowledged the issue but declined full repair coverage, offering only partial “Goodwill assistance.” Because TPMS is a federally mandated safety system, a full-system failure poses the risk of operating the vehicle without tire-pressure warning capability. The dealership quoted approximately $1,000 to restore the system. Subaru’s decision to deny full coverage leaves the safety defect uncorrected.
