While driving at high way speeds engine warning lights began to flash on the dash board. Power loss occured. Pulled over and checked vehicle, waited 10 minutes, restarted vehicle and continued at reduced speed. Vehicle continued to flash lights and lose power with no warning but particularly on hills. Subaru delership in rapid city, south dakota advised us to continue home to saskatoon. Total failure on CVT with replacement cost estimated at $6000+ tax and labor. Wondering if this is the beginning of many such experiences as our year is one of the earliest models with this sealed CVT. No way to check any parts or service it as the unit is sealed.

When driving and approaching a traffic light the car will begin to stutter as if there is a clog in the system. Then it will shut off. I contacted subaru regarding the issue when we first had the car because there was always a loss of power. Our model is the outback 2010. They inspected and said it was a carbon build up in the pistons that would cause this issue. There hasn't been any recalls or subaru notices about this. Now while driving and coming to a stop the car just turns off. On your site nhsta some other customers have been saying that it could also be a bad torque converter. Either way this issue could cause serious accident if not dealt with. The stutter and shutting off happens any time of the day and cold or hot weather it doesn't matter. Some days it happens more often the others and usually after a few times of shutting off the problem does stop for remainder of the day.

We bought our car in 2010 its a subaru outback. There has always been an issue with a loss of power. The dealership at the time said it was caused by excessive carbon build up on the pistons. Its now 2016 and the car will stutter and shut off when you are braking at red lights. To try to beat the stutter and stall, I find myself having to ease off the brakes and try to reapply my brakes to see if it won't shut off. I've avoid many accidents but one of these days I won't be so lucky. I feel a rear end accident is coming. This stutter and stall happens any time during the day and in any weather. This morning there was no issue, this afternoon there might be. Usually once the car stutters and stalls the problem goes away for the day. I read some other complaints on nhsta and they are reporting their similar issue as it being a possible torque converter problem. I'm not sure either way since my mileage puts me over the warranty and I don't want an accident to deal with I would like to see what are options to getting this problem taken care since its been doing this since 2010.

The engine stalls while at a stop or coming to a stop. The rpms suddenly drop and the engine stops. Car will restart and operate normally for a while but the problem has been persistent and is occurring more frequently. The dealer could not replicate the problem and returned the vehicle to us. The next day, it did the same thing. This is a dangerous situation especially when making a turn and experiencing a stall, loss of power steering, and acceleration.

When downshifting to turn or when slowing to stop, the engine regularly sputters and has died twice in the last month causing a loss of power steering and brakes. It also happened once while I was turning left into my neighborhood. Luckily the car had enough residual speed to complete the turn and no traffic was approaching. The car does not have any issue restarting after it happens. I took the car to the dealer this morning, 26 july 2010. After 2 hours, they said they know of the problem, but could not "download the fix".

(1)under normal driving conditions, (2)the engine stalls approaching a stop when the clutch is depressed, it almost stalls every time I drive it whenever approaching a stop. It has only stalled once in the two weeks I have owned it. Possible consequences could be a collision due to loss of power steering, power brakes, and distraction.(3)contacted dealership service department and was advised that they have another vehicle with same problems in for over a month with no fix available yet. I was offered a loaner vehicle, but I declined it. Vehicle is a 2011 subaru outback with 6 speed manual transmission, not a 2010.
