2010 Subaru Forester engine problems

Filed Dec 9, 2025 · Engine · VA

The engine in my 2010 Subaru Forester (VIN: [XXX] ) suffered a sudden and complete mechanical failure on November 15, 2025. While driving, the vehicle abruptly lost power without any warning lights or messages. I was able to pull off the roadway, but the loss of power posed a significant safety risk. Had this occurred in traffic or at highway speeds, it could have caused a collision. The vehicle was inspected the next business day by Wiygul Automotive. Their technicians found no measurable oil on the dipstick and added three quarts just to restart the engine. They confirmed no external oil leaks, and diagnosed the failure as a catastrophic internal oil consumption defect that had been occurring over time. This defect resulted in oil starvation and severe internal engine damage. The engine is fully available for inspection upon request. Wiygul provided a written diagnostic report confirming the cause of failure. The dealership has been notified but has not yet performed an inspection. ​No manufacturer, insurance, or law enforcement inspections have occurred to date. Importantly, the vehicle had a documented pre-purchase inspection on August 7, 2025, which noted the engine oil was significantly overfilled by approximately one quart and that all diagnostic codes had recently been cleared. These findings are consistent with an existing engine issue that would not be detectable by an ordinary consumer. On August 28, 2025, a full synthetic oil service was performed and again documented no external leaks. There were no symptoms, warnings, or drivability indications prior to the sudden loss of power. The failure occurred without warning, and the underlying defect was only discovered after the breakdown. This internal oil consumption defect rendered the vehicle unsafe and unfit for use, and the sudden engine shutdown created a clear risk to my safety and the safety of others on the road.

In brief: I purchased a used 2010 Subaru Forester in Nov. 2022. Because the vehicle gave me many problems, I decided to purchase another vehicle. In June 2025 I went to Fred Beans in Mechanicsburg, PA. They ran a Car Fax on my 2010 Subaru & found, among other things, the odometer of my 2010 Subaru had potentially been rolled back (mileage going from approx. 171,000 to 91,000) prior to my purchase. I filed a report July 03, 2025 with the PSP in Carlisle, PA: Trooper Stevens, badge 12980, Case [XXX]. I am filing this complaint with the federal safety agency as part of the initial report. Please refer to the PSP Case [XXX] for more details & information regarding the ongoing investigation (which includes NJ). The exact date of the rollback/tampering is unknown to me.

I bought a 2010 Subaru Forester vehicle on 05/22/2021 from AutoFair Subaru dealer at 503 Broadway, Haverhill, MA 01832. The car engine was making noises from the day 1 of this purchase. I reported this to the dealership but they denied the facts. Rather they said that I did not know how to drive and was making jokes at me. In month 3 (07/17/21), there was a warning sign on the dashboard. I took the car to them. There was a leak in the tire. It got fixed. I returned with the engine noise still in the car. In month 4 (08/21/21), again there was a safety sign on the dashboard. There was a oil leak in the engine. They charged me a huge amount of bill to repair this. Last Saturday on 10/30/2021, I was going to Walmart. I was on highway I-495 just a could of miles away from the exit, the car engine light was flashing. The engine sound gets louder. As soon as I pulled the car to the roadside, the engine stopped and the whole car was full of smoke. My life was on danger last Saturday. I called the dealer on Monday (11/01/2021). Again, they denied the facts. I demand a full refund of this purchase to avoid any life threatening car accidents in the future.

Head gasket suddenly failed on the highway. This is a known problem Subaru has yet to address and has been present on all their models up to 2010. This is something that Subaru should have addressed years ago but are allowing people to put the safety at risk due to negligence

At 90,000 miles the head gaskets need replacing (a $2600 repair) on a 2010 car that has been taken care of, all oil changes, all maintenance has been done to. Seems like a failed part. Noticed others have complained about the same issue. Just curious how long head gaskets should last under normal use?

I purchased this 2010 Subaru Forester from a private party in 2/2021. It had about 98500 miles, ran smoothly, had service records and was up to date in maintenance. It stalled out in traffic due to low fuel and oil issues. There was oil showing on the dipstick but also oil leaking under the engine when checked at a Subaru service dept. I now found that oil leaks and problems are common according to articles on line. It will cost thousands to either replace the seals or the engine!! For a vehicle of this caliber I expected years of services not immediate oil issues. This is a potential seizing of the engine issue. It consumes too much oil due to the leaks. Is there any pending lawsuits I can join to cover these repairs? Secondly the low tire light is on at all times. Air pressure has been triple checked to no avail.
