About a month ago, the check engine light came on in my car; the cruise control stopped working and this continued intermittently. When I'd start it up, a message would say "Check emission control system." Engine sounds rough; our code reader said P0300, "random misfire on multiple cylinders. Took it to the Subaru dealership today; their code reader had same code; diagnosis was "found roughness counts on all cylinders intermittently;" "checked battery current value and roughness counts, found battery current changes out of specifications and roughness counts go up. Per bulletin replace alternator and belt tensioner to updated design and advise." In other words, the alternator is not working properly, Subaru is aware of this and advises me to purchase a new alternator with "updated design". In other words Subaru is aware their installed alternator is faulty but it's my responsibility to replace it. Why don't they replace it, and/or recall it? This is at 51,500 miles. I am so disappointed in this 2015 Subaru. I had an 01 Forester for 14 years and did not have the kinds of problems I'm having with this one. This is the 3rd relatively major problem this year that I've had (I'll detail the others in subsequent complaints), and once I replace the alternator, I'll be out around $1,800 with Subaru repairs this year. Something is wrong with this picture.

Engine light came on. Owners manual indicated low oil. I just had the oil changed 1,000 miles ago. A check for an oil leak showed there was none. I had oil added and the light went off. The miles per gallon has gone down recently by 10 miles per gallon. I am concerned there is something wrong with the fuel injectors and the engine oil fuel mix. I see that there is some sort of recall on this vehicle related to the intake duct for the turbocharger, whatever that is.

I scheduled to take this vehicle in to a Subaru dealer to see if this is the problem and if Subaru will pay to fix the problem on my relatively new vehicle. This car is not driven hard and should not have this sort of problem since it is only 3.5 years old and has a little over 40,000 miles on it. Hopefully Subaru will stand behind their product and provide some relief and a fix with no charge to me. Time will tell.

Update from Sep 15, 2018: The dealer told me they fixed the computer on my vehicle. They did not charge me anything. My vehicle has stopped burning oil. My gas mileage is back to normal.

The car started ok in the morning but after about 5 minutes of driving what appeared to be all the lights on the dash started flashing and then the service needed light came on. At this point, the car automatically shifted to the drive mode to (S) drive and I was not able to change the drive mode. I pulled over and turned the car off and back on but the need service stayed on and I was only able to drive my car in (S) drive. The following day I started up my car and it worked fine... no service light on anymore and I was able to drive in any drive mode.

Next time I brought my car to the dealership service I told them of the issue. They ran diagnostics and could not find any issue. They stated it might have been the gas cap that was not put on tightly. Really?!?
