Rough Idle All Times, Check Engine Light Comes On

2014 Subaru Forester

This problem may be covered under warranty. Ask your Subaru dealer.

CarComplaints.com Notes: Is burning a quart of oil every 1,000 miles normal? Depends on who you ask. While Subaru says it's within "normal specifications," owners wonder why they need to top off their oil reservoir 4 times between every 5,000 mile oil change.

I purchased a 2014 Subaru Forester on March 23, 2013. Approximately 2 months after purchase, the check engine light and hill assist warning lights came on. I immediately stopped, called the dealership and was told this happened with Subarus sometimes and to continue driving. They told me the only thing I wouldn't be able to use when this happened was the cruise control. So, no big deal, I thought it was just a glitch and sure enough the warning lights eventually went off only to come back on again soon after. This has gone on for 3 years now and the engine runs very rough - to the point where it jerks and hesitates badly, especially on acceleration.

The dealership is well aware of these issues as I mention it every time I bring it in for servicing however, each time I am told they don't know how to fix it. My last "repair", in Aug, 2016 involved a major decarbonization service and cost me $500 which resulted in 2 days of smooth driving, only to be followed by the warning lights coming back on and the engine running very rough again. Since I service my vehicle on a regular basis and mention this problem each time I bring it in - how can they possibly not figure it out?? They just tell me this "never happens" but coincidentally, a few months ago when I brought it in, I was taking the dealer shuttle with a man who told me his Forester was in for the exact same thing!!! How weird is that???

I am so frustrated and feel Subaru has totally failed as far as standing by their product. The other day, I was trying to merge into traffic and the engine hesitated so much that I wasn't sure I was going to make it! This is a safety issue! There is no doubt in my mind that some time down the road, an accident will be inevitable...and then what?? Subaru - stand by your product!!! Acknowledge that there is something very wrong with the engine/catalytic converter (or whatever the problem is) and fix it so that these hesitation/acceleration issues stop. The other day, I was trying to merge into traffic and the engine hesitated so much that I wasn't sure I was going to make it!! This is a safety issue!

I have voiced my concerns to Subaru Canada to no avail and feel I am wasting by breath. As a business, it is Subaru's reputation on the line but they don't seem to mind. As a customer, I can only pass on to others what my experience with Subaru has been...terrible!
