  • Manual transmission
  • 2,050 miles
We bought a 2010 Subaru Outback with manual transmission in July 2010. It has stalled twice (once in September and once in October) while driving about 25 mph with the clutch depressed and making a lefthand turn into oncoming traffic. In both instances of stalling, there was a slight incline in the hill. Since I was turning into oncoming traffic this was a very dangerous situation. The car started up immediately after I pulled to side of road. I am bringing in this car for service this upcoming week. The Subaru dealer I just spoke with said that they have had to service multiple cars with this stalling issue for the 2010 model. This issue is extremely dangerous and Subaru needs to provide a comprehensive fix before people are hurt or die--perhaps some people have been hurt already?

I have a 2010 Subaru Outback pzev 6-sp manual. The engine will sometimes stall (4 times and counting, in the past 4 months) when the clutch is depressed to slow down for a stop sign or light. Also at times the engine will stumble when the clutch is depressed for upshifts (numerous times over the months). The problem is aggravated when the A/C is on. This stall problem can happen at any speed, most notably at 70kph in 4th gear - shifting to neutral while approaching a red light. The orange and red dash lights will come on, steering and braking become heavy, the A/C shuts off while the fan continues to run and a restart with the key is necessary. Thank god this has not yet happened on an on-ramp or off-ramp.

2010 Subaru Outback stalling and choking off. Dealer unable to duplicate at this time. Car put in shop 2X so far with no solution. Car stalled or cut off 2 to 3 times a day. No trend. We feel very unsafe driving this car. The dealer loaned us a 2010 Subaru Outback, and this car has the same problem. The car we own is approx. 4/5 months old with approx. 13000 miles on car. The loaner we have has 3500 miles on car at this time. We don't feel this is related to just our car being the loaner we are driving has the same problem.

Outback 4-cyl

  • 13,566 miles
The 2010 Subaru Outback 4 cylinder, standard, has a significant stall flaw. The vehicle will stall in traffic when the clutch is pressed. This happened on the interstate while accelerating on the onramp. At 50 mph with the clutch depressed, the engine stalled resulting in no power steering. A tractor trailer barely avoided hitting this car as we maneuvered to the side. The engine started up promptly. This is the 10th time the car has stalled and the most serious to date. Other incidents have been at lower speeds with the clutch depressed: 20 mph, left turns, and decelerating. The local dealership has inspected the car 3 times, but has not duplicated the issue.

2010 Subaru Outback 2.5L cvt. Engine hesitates or stalls when starting up from a stop or low speed, especially if uphill. Usually before engine is fully warmed up but also when warm. No difference with or without A/C. occurs at least once daily. Problem started at about 5000 miles on odometer. Several near misses when trying to cross traffic. Dealer says there is no fix. But similar problem with same year manual transmission Subaru's has a fix involving the ECU.

2010 Subaru Outback, 6 spd mt with 2,521 miles. Car has nearly stalled on numerous occasions when slowing or downshifting with clutch depressed and with ac on. More noticeable during hot weather (90+ degrees). Local dealer denied knowledge of this issue, only acknowledged cold engine stalling and they don't think that "fix" applies but will check to see if car could also be affected by that issue. Potential for being rear ended (and possibly pushed in to oncoming traffic) is high if car stalls in traffic due to loss of brake and steering control.

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".

  • 5,000 miles
I purchased a 2010 Subaru Outback 2.5I with a 6 speed manual transmission on May 2010. What has been happening is upon fully depressing the clutch to either slow the car down and/or bring the car to a coast the engine rpms drops rather rapidly which on several occasions has resulted in the vehicle borderline stalling before the engine computer compensates by increasing the idle slightly while coasting or slowing down with the clutch depressed. This is far more prevalent when the A/C is running. Today (sun 7/25) I was approaching a right turn, the A/C was running. I started the process of slowing down the car by fully depressing the clutch and braking. When I started to turn the steering wheel to enter the turn I barely could do so. The reason for this is the engine this time stalled. Generally you can hear the engine shudder before a stall, in this case it did not. It almost resulted in the vehicle hitting a pole with my two young children inside. The car restarted right away and I was able to resume normal operations. During the course of this same day on at least two more occasion I fully depressed the clutch to either slow the car or coast and the car shudder indicating a potential stall but the car compensated. This issue needs to be addressed asap because it will result in a serious accident. Thank you.

The engine stalls when coming to a stop while the air condition is on. The event occurs when slowing down, getting ready to down shift. When the clutch is pressed in, the engine stops before the car comes to a compete stop. The issue is not repeatable. It happens once in a while with no apparent cause other than the air conditioning being on. The issue has never happened while the air conditioning is switched off.

  • 50 miles
I purchased my new 2011 2.5 premium 6mt (non-pzev) Subaru Outback on June 25th, 2010. Just a few days later, with only 50 miles on the car and my first time driving with the A/C on, I experienced my first near-stall engine shudder while coming to a stop. As outside temperatures have gone up lately, so has my use of A/C, and so have my occurrences of engine stalls and near-stall shudders. The revs will drop below 500rpm, the HVAC fan speed will audibly slow, sometimes the "battery/alternator" warning light will illuminate on the instrument cluster, and the headlights will dim. The shudder is sometimes quite violent, and shakes the car. A few times, the car has actually stalled out. This could be a serious safety issue, as power steering and power brakes are lost during an engine stall. I'm 33 years old. Iżve been driving manuals since 17. This is my 3rd Subaru and my 6th car ż all manuals. IżM pretty sure I've got my head wrapped around driving stick. The shudders and stalls will occur even if the gear stick is in neutral, so I know this is not due to insufficient or improper use of the clutch. The second issue Iżve been having with my new Outback is a slight shake or shudder in the steering wheel at highway speeds.

(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.

  • 2,554 miles
I bought my Subaru Outback 2010 in early Apr. While I am fairly satisfied with the vehicle, I encountered 4 times totally that the engine shut off itself while I was driving. Normally it happens when I was slowing down and sometimes switching lanes. When that happens, I have to restart engine quickly to have full control of the vehicle. Since when engine is off, power break and steering system will not work. I had to use parking break to stop the car from rolling the first two times since I was nervous, and I didn't know the engine was off. 2 weeks ago, I brought my car to local dealer to check. Dealer technician just thought what I said doesn't make sense at all. They didn't think it could happen at all. (they still don't, not sure why they have so much confidence). Anyway, dealer scanned the computer code and nothing found. So, they returned car to me and told me nothing was wrong, it is safe to drive. I don't know how to reproduce the problem. I continued driving for 2 weeks, then it happened two more times. I have called dealer to schedule another appointment, but I doubt they can find anything either this time. They just don't think that could happen. I did some research on internet, and I did find a number of people complaining about the same problem. Now I feel maybe Subaru can believe our problem is real now? thanks.
