Once again I was driving on the interstate for about two hours at around 75 mph, when the car seemed to shift into a lower gear. The rpm's increased and the car slowed significantly. I tried to accelerate but there was no response. I pulled to the shoulder and came to a complete stop, the engine shutdown. I tried to restart the engine, it turned but wouldn't start.

I called Subaru Roadside Assistance several times before I was actually able to talk with someone. I explained the problem and they told me it would cost me $260.00 to be towed to the nearest Subaru dealer. I told them I had AAA and would try them. During the phone calls I tried to start the car several times. The engine would turn but no luck.

Called AAA and was bounced around several prompts. While on hold I tried once again to start the car. This time it started (20 minutes or so after it initially shutdown) although the check engine light was on and there were several prompts of things that should be checked, no cruise control. Put the car in drive, pushed the accelerator and it just crawled, no power at all. I put it in manual and shifted with the paddles and was able to slowly get the car up to 65 mph, that was it. I was able to get to the next exit and filled the gas tank (it was at a little more than an 1/8 of a tank). After filling the tank the car ran fairly normally and so I drove it to the dealer.

This time when they ran the diagnostics it came back with a "Fuel Pressure Sensor Fault". Should have the car back in a couple of days at a cost of $725.00 for repairs.

I was driving on interstate going 75 mph and my car suddenly acted like I was on ice and shut down. Tons of traffic behind me and I was in the passing lane with no place to go. I stepped on the accelerator pedal not believing what was happening and NOTHING!! I drifted to the median while trying to signal those coming up behind me by turning on my Hazard Flashers. It could have been a fatal accident for me and many others had I not been able to get off road.

Now I am searching to see if there is a recall on this condition. I have researched online and find many others with the same type of incident happening. Subaru needs to pay attention to this. VERY SERIOUS. I am afraid to drive this car now. Calling dealer tomorrow first thing.

Forester Limited 2.5L

  • Automatic transmission
  • 56,000 miles

While driving down the interstate for less than two hours, the car's mileage slowly started to drop from it's standard 30ish to 25 on the highway. It soon stopped accelerating. Whenever we pushed the gas, it failed to accelerate and began to slow down on the highway. We turned the car off as we figured it might've overheated (unfortunately there's no gauge/meter on the dash to determine this safely). We attempted to turn the car back on after waiting about 20-30 min I but the engine wouldn't turn (the battery worked though) We had to pull over on the side and get towed off the highway. An hour later after getting the car towed, the car's engine would turn and run fine. We will took it to Subaru to get it checked out- they did a full diagnostic and found no problem with the car. Not comforting- I've done all the routine maintenance on time/early.

Second time this happened- While driving down the interstate for less than two hours, the car's mileage slowly started to drop from it's standard 30ish to 25 on the highway. It soon stopped accelerating. Whenever we pushed the gas, it failed to accelerate and began to slow down on the highway.

We attempted to turn the car back on after waiting about 20-30 min but the engine wouldn't turn (the battery worked though). We had to pull over on the side and get towed off the highway. An hour later after getting the car towed, the car's engine turned and run fine. We took it to Pep Boys to get it checked out- they did a full diagnostic and found no problem with the car, said it's good to go yet again! I don't feel safe driving the car anymore and having it break down in the heat of summer on the highway in the middle of nowhere is not safe and extremely frustrating.

engine stalls/dies while driving

Second engine failure in less than a month. Driving for 4-5 hours on the interstate in dry weather. Cruise set at 80 mph. Low fuel indicator had just come on and car reported 50 miles left on the tank. Engine revved like it had been shifted into neutral, and then sputtered out as if it had run out of gas. Coasted and braked it over to the shoulder. Had it towed into a local truck stop. The mechanic there pulled a "low fuel pressure" code off it, added two gallons, and it started right up. He said I simply ran out of gas. Gee, aren't I dumb? But I topped it off afterwards and only 11 gallons went in, which means, counting the two he added, there was still two gallons in the tank when it died. That makes sense because I'd have about 50 miles left and that's about when the fuel indicator light comes on. So it wasn't just out of gas, but there appears to be something wrong with the fuel system, like the fuel pump, fuel pump relay, or fuel filter. But I'm not sure which. I brought it back to Green Subaru in Springfield, IL. They again were unable to diagnose a problem and said all the fuel system parts they tested were operating to spec and kicked it out the door without doing any repair work.

The dealer offered no further assistance or suggestions on how to fix the problem, other than to say, "try and bring it again when the gas is low". But I've driven it to near empty a couple times without the problem being reproduced. It seems to happen after the car has been on the road for several hours already. So duplicating it for the mechanics is going to be intrusive and not practical.

I wound up having to try and diagnose this myself. I found a couple cases on this site and the Forester owners forum with matching symptoms: engine dies and revs while in cruise after a few hours, no error code after the first failure, followed by low fuel pressure codes as if it had run out of gas the next time(s). In both cases the problem turned out to be a bad fuel pump relay. The part and repair isn't that expensive or difficult, so I asked the dealer to just replace that part based on these other reported cases. They could at least make an effort to try and fix this problem, right? Even if they had to eat a few bucks guessing, just to keep their customers happy and safe? Nope. I scheduled to have the part replaced, only to find out they hadn't even ordered the part yet, so I dropped it off for no reason. Then all they said was they couldn't diagnose or reproduce the problem. Both the dealer and Subaru of America said the problem had to be duplicated before they would do any work under the vehicle's warranty.

Green Subaru's management wound up being defensive and not helpful, making excuses for why they couldn't provide any further help and acting incredulous toward my problem. Subaru of America offered no further ideas or assistance either, beyond saying the problem had to be duplicated... which might happen at random in the next couple of weeks of driving it. Meanwhile I have a defective car and Subaru was unwilling to at least try to make a repair based on the customer's recommendation, which is costing me hundreds of dollars in tows and down time.

Taking it to a third party mechanic and will try to have this diagnosed and the fuel pump relay replaced on my own dime now and see if the problem reoccurs.

engine stalls/dies while driving

Driving on the interstate for about 4 hours in intermittent rain. Had between 1/8th and 1/4th of a tank. Cruise control set at 76 mph, the engine without warning revved as if it had been shifted into neutral (but was still in Drive) followed by a loss of power. Coasted and braked it over to the shoulder, all lights on the dash came on as it came to a stop. Tried a restart several times. The starter cranked strongly, but the engine wouldn't kick over. Had the car towed to Green Subaru in Springfield, IL. The next morning the dealer reported that the car started right up and there were no error codes on the system. They said it might have been "moisture" getting into the system, but were unable to duplicate the problem. They said the car was safe to drive and kicked it out the door without doing any work on it beyond what seemed like a superficial diagnostic. Clearly it wasn't though, the problem reoccurred under dry conditions, so it wasn't "moisture".

Forester ES

My mom was driving, merging onto highway, and all dash lights came on and car shut off. She was able to pull over and had to call 911. State troopers were prompt and assisted her with a tow truck. The highway was busy during this time and dangerous for someone to be broken down with no hazard lights. Vehicle towed to Subaru and they said it was a broken belt. Fixed in 10 minutes but this was a dangerous situation and shouldn't have happened to a car that has been driven for only two years with so little mileage. I am happy that no one was hurt but disappointed with the quality of this vehicle.
