When the outside temperature is below 32 degrees F, there is a strong odor of exhaust fumes or gas coming from the engine. When you turn the climate control to the cabin air recirculating position the smell decreases dramatically. This car must be driven with a window partially open for fresh air for safety. The odor is strong enough to cause nausea. There are numerous problems on the internet regarding this issue with Subaru. Subaru has never issued a recall to the best of by knowledge.

Outback 4-cyl

  • 23,000 miles
Engine made a sudden rattling sound that got progressively louder, then had a loud banging sound.after a few days of investigation, it was found that the torque converter bolt came loose, bounced around in my engine, damaging a plate and "taking a few 'chunks' out of the engine block, according to the mechanic.the mechanic said in his professional opinion, the only way the bolt could have been loose, is that is was not tightened properly on the assembly line.this was the first time this has ever happened to a Subaru that they are aware of.the car is 6years old and only had been driven for 5years(bought it in 2009 with 33 miles on it, as it hadn't sold in 2008), and it has only 23,000 miles on it. There is no recall, and my warranty expired 7months ago. Subaru said they would cover half the cost of repairs, but we are still pursuing options.

Oil leaking from passenger side head gasket onto exhaust manifold. Read web and see this is a very common failure item for Subaru engines 2000 thru 2009. My concern is potential fire. Repair costs $1800-3000. Widespread issue and fire hazard thus I hope Subaru will address this design issue more proactively.

Leaking headgasket on a 6 year old Subaru Outback 2.5 with 79,000 miles. Repair job cost of $2,000. Head gasket issues are a major complaint/defect on Subaru 2.5 4cyl engines. Subaru should either offer to subsidize or cover major repair cost.

The head gasket is leaking coolant into the oil. Advised not to drive the car until head gasket replaced. Subaru used in 2007 a paper gasket which has been found not to hold up. New had gasket much stronger. Trying to get Subaru to warranty this serious safety problem. The car has only 43,800 miles on it.

Outback 6-cyl

  • 66,270 miles
While driving our 2007 Subaru Outback sw on a 6 lane divided highway at 65 mph, the car suddenly decelerated and lost all gas pedal response. My wife was able to move the car to the side of the road although she almost caused an accident due to surrounding traffic. The car started flashing the cruise control, traction control, and check engine dash lights. After allowing the car to sit for a few minutes, my wife was able to start the car again and get home. I checked the error codes and got a P02138. I did some research and found numerous other people experiencing the same issue on the Subaru blogs. All of the other reports pointed to the same source(s) the gas pedal position sensor or throttle position sensor. Most reported Subaru service departments claiming no knowledge of the issue ever happening before. Both my wife and I have had the same thing happen several times since in both local and highway traffic. I have cleaned the terminals on both sensors and this seems to help, but the problem always returns. I read where several other drivers had the gas pedal assembly changed and the issue seemed to be resolved. This seems to be a severe safety issue. Having a car suddenly become dead on the road in the middle of traffic is dangerous to anyone around.
