Gas Recirculation Valve (egr Valve) problems of the 2014 Subaru Forester

While driving vehicle on highway speeds in temperatures around 85-90 (or greater) degrees vehicle will not allow acceleration. Vehicle stumbles, detonates and will not allow the driver to apply power without hesitation and engine stumbles. This problem can be recreated at will and yet the vehicle will not throw a cel unless a larger failure happens, which typically is the #3 cylinder burns off the spark plug electrode and damages the engine. Subaru is aware of the issue but considers this condition normal. The vehicle is not appropriately mapped for the Subaru suggested fuel octane level, has turbo boost piping leaks according to numerous individuals.

At cold starting, approximately one time out of 20, the car is very difficult to start. It cranks for up to 10 seconds before starting. I don't know if it's a fuel delivery or an ignition problem. It has happened at ambient temperatures from 35 to 65 degrees. If I didn't continue cranking the engine to an extent that I think is harmful to it, it wouldn't start. I consider that a safety issue, if I needed to get the car going quickly.

After I purchased my vehicle, I noticed a hesitation between 20 - 40 mph. This is the first year for the Forester's to have a cvt engine so I thought it needed broken in. I also went through 3 cycles of filling up my gas tank from 3 different gas stations and the hesitation continued. The first time I brought it in the technician said he overfilled the oil a slight bit, removed it, and I should notice a difference. No difference. I brought my vehicle back to the dealership addressing the same issue. They performed the tests Subaru of America (soa) suggested and nothing was found. The last time it happened, > month ago, I feared an accident because it hesitated through an intersection. I returned the vehicle wanting answers. Subaru sent out their own technician to gather information to send to fuji and what I was told was that their equipment did not find anything wrong and that it was normal for a cvt engine. I test drove several more Foresters and they all had varying degrees of hesitation and all had different mileage on them.
