Subaru Forester 2.5 2010 warning light showing

Asked by Jul 10, 2017 at 12:32 AM about the 2010 Subaru Forester 2.5 X

Question type: Maintenance & Repair

Few days back i was driving and i heard a strange sound suddenly coming from the car. when i stopped and opened the hood i noticed that Alternator belt had snapped since i was on the highway i drove car for few kilometers & stopped at a safe place and got belt replaced on stop by mobile mechanic team.

By that time battery was completely drained and i had to jump start the car.

It worked smoothly on highway but i noticed that while car stops or slows down at signal (red-light) it seems to loose power but car doesn't shut off. i also noticed car engine turn off while reversing (this happened only twice in few days)
Today i noticed warning light showing up for half a second when i stop at parking area and light goes off when completely when i turn off the AC.

I started having these problem after changing the Alternator belt. what could be the cause of this problem as i can sense something but don't know what it could be

Light which show in yellow
Vehicle Dynamics Control System

Light which show in Green

Light which show in RED

You need to have the engine trouble codes read.

Reply from another forum for this question? Hello, I would pay close attention to the pulleys that the belt drives. The belt could have broken due to age and dry rot, or it could have broken due to an intermittently binding pulley. A second thought would be to check your battery to see if it is fully charged, and if it able to handle a load. The vehicle needs the battery voltage to run all your accessories when at idle -- stopped at a stop sign or traffic light, and similar instances. If your battery has no capacity, it can make odd electrical things happen. This is what it sounds like, but of course, I cannot be sure. Check the battery, replace or charge as needed, check the alternator, power steering, air conditioning, tensioner and idler pulleys. That would be my recommendation from hearing your story.
