Gas Recirculation Valve (egr Valve) problems of the 2015 Subaru Forester

Vehicle had 82,401 miles when on January 19, 2021 the "engine low level warning light" illuminated. Oil level on dip-stick measured at very end of stick. Added 1qt 0-20w synthetic oil, scheduled a complete "leak-down test" at dan o'brien Subaru in vermont. The service also performed a 2k mile "consolidated engine oil consumption test". The results measured no oil consumption but the "compression & leak-down test" measured: cylinder #1 = 160psi & 5%, #2 = 148psi & 25%, #3 = 165psi & 5%, #4 = 153psi & 20%. They reported most of "leakage was going into block past pistons and some was "leaking" by intake valves. Recommend replacing short-block". To date, due to the "oil consumption test" and not the "compression and leak-down test" results, the dealer is not willing to repair and/or remedy the problem, even though, the compression and leak-down test indicates a "severe" degradation to the engine with only 84,770 miles. This is well below Subaru's advertised 100,000 mile drive-train warranty publicized. Note: this vehicle has been serviced regularly by only Subaru dealerships since it was purchased in 2017, and the carfax report stated it was only used by Subaru dealership as a corporate personnel rental before then. Additionally the current carfax report showed no incidents or accidents and all vehicle services maintained properly.

Engine shut off while driving on interstate at 70 mph. No warning or engine sputtering. Plenty of fuel. Foggy weather and 37degrees f. Dash lights stayed on same as if it was in the on position. After 1 1/2 hours vehicle restarted and hasn't shut down while driving since. Took in to the dealer and they said battery was weak and replaced that. They said other engine codes pointed to power supply. I have never heard of a vehicle quitting while driving because of a weak battery so am suspicious about this as a good repair. This is potentially a very dangerous problem.

Driving with eyesight enabled at 75mph in heavy traffic on loop 202 freeway at approximately 2:30pm local time. Weather was sunny and dry, approximately 97 degrees. Nearly resulting in a crash. Feet were not on any pedal. Vehicle suddenly lost power and revd to redline as if the car was in neutral, engine then shut off. Instrument cluster showed every warning light illuminated. Eyesight display showed a vehicle directly in front yet there was no vehicle present. I checked to make sure gear selector was still in drive. Pressed the accelerator which had no affect, no rpm change. Was able to coast a short distance but still obstructed traffic. Police had to shut down freeway to move my vehicle to the shoulder. Attempts to restart vehicle failed, all warning lights on instrument cluster illuminate any time the key is turned to the "on" position. Subaru roadside assistance towed vehicle to local Subaru dealer, awaiting diagnosis.

The current mileage of my car is 45,751. I faithfully follow all maintenance schedule, particularly, oil changes. On two occasions now, my oil light has come on, the last one 2,000 miles before the next oil change. When I questioned the Subaru dealership service guy about this, he said, well, I need to have oil changes at 5,000k instead of the recommended 6000k. He said 6000k is for ideal driving condition - temperature should not below 30 degrees, no stopping here and there, no idling, etc. Synthetic oil is expensive enough and I certainly do not need to be paying someone to top it off every time. And I do not want to be caught with this problem while I'm travelling. I bought this car new and at this mileage, I should not be having this problem. Fyi, the mileage of this car is mostly highway miles. From reading online, I learned that other Forester owners are having problem with oil burning as well. There is definitely something wrong with the car and Subaru needs to remedy this. Would appreciate any assistance to this problem. Thank you.
