“On June 24, 2026, my stock 2018 Subaru WRX Limited experienced a sudden catastrophic internal engine failure at approximately 67,319 miles while I was driving. I first heard an intermittent ticking/noise under acceleration. Within about two miles, the noise became much louder, followed by a loud pop, sudden loss of power, and smoke from the engine bay. I was able to get the vehicle stopped safely. I do not recall a warning light or message before the failure. The vehicle was towed to an authorized Subaru dealer. A full engine teardown found catastrophic internal damage concentrated in cylinders/rod bearings 2 and 3, including multiple holes in the engine block, while cylinders 1 and 4 were comparatively intact. The service advisor stated that the damage pattern did not appear consistent with generalized lack of oil and that recent over-revving was not indicated by the vehicle data. An independent inspection on September 17, 2026 confirmed catastrophic internal material failure involving cylinders 2 and 3, crankshaft damage, a deeply gouged cylinder wall, and metal debris associated with the failure.

“2/17/2026 Mileage 96,000 Subaru case number Case # 260217-2101937 Vehicle intermittently indicates reverse gear while driving forward at speed. Backup camera activates and reverse lights illuminate while in forward motion. This condition matches NHTSA Recall 22V-522000. The recall repair was previously performed but the safety defect persists. Manufacturer was contacted and declined further repair despite active safety condition.”
“Unknown. I am unsure of the issue. However, there is an issue. & it is very dangerous... This has happend about 5, or 6 times now. Sometimes when I am making a turn (I believe it is related to the braking), My steering wheel locks up (as if the key isn't in the ignition). It only lasts for a second, or two. But again, it is very dangerous. & I am at my wits end trying to figure out what the issue is. I am unsure of the issue. But, there is an issue. & it is dangerous for myself, & others. I am trying to limit my driving, but I still have bills to pay, & jobs to do. So please get back to me at your earliest convenience. Thank You, & God Bless.”
