Has anybody had problems with their Subaru Forester Turbo ECM (Engine Control Module) ?

Asked by Aug 03, 2016 at 09:50 AM about the 2015 Subaru Forester 2.0XT Touring

Question type: Maintenance & Repair

I received a notice from Subaru for a required service program update to
reprogram the Engine Control Module (ECM) on my 2015 Forester 2.0XT
Turbo Touring model.  Since then, my car has not run  properly.  The  car
lurches rapidly with acceleration in  the 1800 to 2000 rpm range.  Is anyone
else having  similar problems?  What has Subaru done for you to fix  this
problem ?

My 2015 Forester XT had the ECM recall in March 2016 and has been lurching ans stuttering since, despite 2 software reflashes and cleaning/decarbonization of the valves. Their next uggestion is to replace the ENGINE! I am in contact with Subaru customer service as my local service manager is livid and does not believe that Subaru has a fix for this and is putting people off to buy time. Their service department is now telling people openly that this recall often causes these lurching and stuttering problems and there is no way to return the engine's computer to stock once they mess with it. Please file a customer service complaint ASAP and warn others not to have the recall done. FYI I love Subarus and always have. I am trying to remain a loyal customer by asking them to do the right thing and replace my vehicle which meets Lemon Law Criteria.

I have had the same problem with my 2015 Forester XT since Subaru did the ECM recall in March 2016. Subaru has stated that they are having these problems in the warmer southwestern US climates, specifically Las Vegas, Tucson, Phoenix, etc. I have allowed teams of Subaru engineers from Japan and Subaru Corporation of America to evaluate my car trying to come up with a fix. 4000 miles and a speeding ticket later showing a Subaru Corp employee speeding in my car, the only recommended fix was to replace my engine and wiring harness. Subaru has done engine replacements on Foresters with similar problems, but the lurching and stuttering returned shortly after the engine replacement. Subaru has stated that they have a software fix but have to wait about 6 months to get approval from the Environmental Protection Agency to perform the software fix. Unfortunately, my car was just beyond the lemon law limit of 24000 when this whole goat rope began. So, I have been negotiating with SubCorp of America to get a new car. Sounds promising, but no results yet. I agree with the previous commenter that anyone having these problems after the ECM recall should file a complaint and take action before their car exceeds Lemon Law Criteria.

I have had the same problem with my 2014 Forester XT since Subaru did the ECM recall in March 2016. It does not qualify the Lemon law either for me. They change the ECM and wire. Let hope that my car still can work like a normal car. Previous commenter did you have a chance to get a new car and What thing you key point to dispute to replace your car for a new car

Same exact problems here with my 2015 forester XT. The engine started losing power like a piston wasn't firing and then started losing power on the freeway, blowing black smoke. Dealer said that the spark plugs melted and they had to replace the entire motor.

My dealership trying to fix a problem that I did not notice with my 2014 Forester, upgraded the software. Car works terrible after the upgrade. Radical changes in acceleration. Sometimes normal. Sometimes no power. Mpg also radically changes and is 20-30% lower in general. I would not buy a car that runs like this.
