Outback 6-cyl

  • 90,775 miles


In the summer of 2011 I was driving on the highway at approx 75mph. All of a sudden temp gauge made a big jump into the red zone and the engine started making loud upsetting sounds. Pulled off the highway and right at the exit lost power steering and the car died. Car was diagnosed with blown head gaskets and cracked engine block. The entire engine was replaced under warranty (approx $8000 replacement). Fast forward to June 2014. The new engine did exactly the same thing. Temperature shot up on the highway, engine died, head gaskets once again have blown. This new engine was four years old and had only 30,000 miles on it. Car has had regular oil changes and service throughout its lifetime. I am currently having my situation reviewed by Subaru of America. I am hoping they will cover the repair costs.

Our 2006 Subaru Outback needs the head gaskets and rear main seal replaced. The vehicle has been maintained to manufacturer recommendations. This seems to be a common issue for the 2.5 engine and should be recalled.

Subaru head gasket has failed. This is a known issue across just about all Subaru models with 2.5 engine. If you contact various Subaru owners you will see that this head gasket failure is high at an abnormal rate. I am hoping that you investigate and hold the responsible and accountable. This is unacceptable.

Happened twice in one week. All of sudden, accelerator not responsive and lost of power. Check engine light comes on and cruise flashing. After turning on and off or stay off for a night, lights went out themselves. Error code P2138 accelerator position sensor. Check sensor no obvious loose on connector. Press connect on and no issue so far. It seems the connector too close to the floor and easy to kicked or touched by foot. \ car was bought in buffalo West herr Subaru and used in toronto.

No warning lights. No precussors. Vehicle purchased 5/13 w 86K on it. Dealer hides behind 'as is' or expensive warranty after bragging about 'award winning dealership'. first oil change at 90896 in 8/13= forced dealer to replace head gasket-leaking-smelled oil on test drive-dealer poo-poo'd as recent oil change prior to sale. I paid for timing belt. 10/13-car died pulling into driveway with horrendous knocking sound. 2 qualified mechanics checked my car in driveway-saw metallic sheen in oil, oil dipstick at proper level. Car towed back to above 'award winning dealer'. service accuses me of over filling oil- it was never touched by anyone other than them on 8/13, then tells me engine must have been run with no oil causing damage.(car due now for next oil change) have forced them to recheck timing belt function-they have ruled that out and state most likely a rod or two shot in lower engine. No help offered to me. Possession of car by me-less than 6 months &less than 10K miles, paid 11thousand. Towing it to a non-dealer dependable local Subaru guy for replacement engine. Do not buy as is. Do not buy expensive extended warranties. Insist greedy dealerships put their mouths where there trophy showcases are and make it right!!! I have owned Subaru for over 2 decades....no more if their engines continue to fail leaving loyal customers high and dry. Going back to Toyota, or maybe even Hyundai! I work in the medical field and I will negatively speak loud and often about this dealer to hundreds of people whether directly or indirectly so anyone and everyone can hear. Now off to social media to disseminate my treatment there as well.

Outback 5-cyl

  • 73,956 miles
Four times in one month prior the above date, this vehicle stopped running in traffic. It would not restart. Most importantly, the automatic transmission could not be taken out of gear and put into park!! in addition, the emergency brake failed to properly keep the vehicle from rolling in traffic. The most recent time this happened, the driver was in heavy traffic on a hill and the emergency brake again did not properly hold the vehicle. The driver had to open her door, exit the vehicle in order to physically stop it from rolling downhill in traffic and was nearly ran over by a passing semi trailer truck. This is a well maintained vehicle, often through the dealer it was purchased from. During this time, the vehicle was towed twice to the dealer. They diagnosed the problem as being caused by electronic computer parts malfunction. After these expensive and possibly unnecessary repairs the problem still persisted. The vehicle continued to stop for no reason in traffic and would not restart. Each time this happened, the vehicle could not be taken out of gear and put into park!! I know of no other vehicle where this type of problem has happened. After the latest breakdown, upon inspection, the dealer located a section of wire loom that had worn bare and possibly had caused a short in the electrical system. This worn spot in the wire loom may have tripped up the logic in the vehicle computer and been the reason the driver could not put the vehicle in park after breaking down in traffic. If this electrical wire loom caused this "malfunction", it would put anyone in this vehicle in a position where there is great potential for serious injury, or death. This problem should be looked into by your department in order to make sure this does not happen again to someone else.

There have been two incidents so far. One was traveling on the freeway at 65mph when the throttle completely stopped responding. The other incident occurred at much lower speeds when turning a corner and the throttle no longer responded. In both cases the car would not accelerate or maintain speed. Pressing on the accelerator did not have any effect at all. In both cases the car would "coast" along at whatever speed the engine idling would move it - roughly 15 mph.

While driving on interstate highway, vehicle lost engine power. Electric was still on. Gas pedal did not work. Cel and cruise control lights both blinking. Was able to maintain 15 mph on flat road, and barley any speed on incline. Got off highway near home and shut of engine. Waited and tried to start back up. 30 seconds of cranking, and nothing. Waited another minute and it started. Got home and pulled a P2138 code. Pulled wiring harness off gas pedal and reseated it. Reset the cel and everything has been fine since. Scary situation, especially at 65mph during thanksgiving eve rush-hour.
