Filed Jan 23, 2026 · Engine · CO

At 77,000 miles, my vehicle suffered a major failure where the #2 connecting rod and piston were destroyed, requiring a short block replacement. This repair was performed by Autonation West Subaru in Golden, Colorado and was covered under the SAS gold plan, certified pre-owned 7yr/100,00mi. warranty purchased with the vehicle. According to the technician's report at that time, the failure was so violent it cracked the engine block and contaminated the entire oiling system with metal shrapnel. A short 18,000 miles after receiving the vehicle back at 95,335 miles the clutch went out, needing to be replaced. Keep in mind that this clutch had recently been replaced at 35,757mi. by this same dealership who at the time charged me $900 even though I had just bought the car in July of 2021 with 22,000mi on it. Now, I am at 128,000 miles—only 50,000 miles after the dealership repair—and the engine has failed again. Fortunately, just as I was pulling up to my friend's house, it stalled with an engine code of p0171 present and several dash lights illuminated. And all I've gotten it to do is crank but not start, since early September. In October I had it towed to Subie Smith in Thornton, Colorado. Who did an inspection and compression test, reporting low compression in 2 of the 4 cylinders. And recommended a full engine replacement, either used or new. I don't have the means to afford an engine replacement now out of warranty.

The vehicle stalled at highway speed as I began to decelerate on the interstate highway. I attempted several times to restart the engine until the vehicle reach a rolling stop in the middle of the 4 lane highway. I turned on my hazard lights and after approximately a minute I managed engage the engine for a brief period to reach the shoulder of the highway before the engine stalled again. There were no indicators or warning lights on. I tried several times to start the engine with no success so I called for service. After waiting for 30 minutes, I tried to start the car again; this time the rpms stayed normal. I drove to the car dealership for service. On the first day the technicians were able to replicate the issue but could not identify anything wrong with the vehicle. The technicians tested my fuel octane and electrical system. The technicians then ran a full diagnostic test on the car and still they could not find anything. My vehicle has been with the subaru technicians for 6 days and so far the problem is still unknown.
