“Head gasket failed at 125k miles. I spent $1725 getting the head gasket & cylinder bolts replaced. The head gasket is now failing again 9 mos & 12k miles later. I have always meticulously maintained this car.”

NHTSA complaint #10210975, filed 2007-12, 125,654 miles

“Head gasket failed on 1999 Subaru at 38,000. Car was maintained religiously. Subaru recall was never sent to me. I was told my car was the 'wrong phase engine' to be covered under warranty. Car had overheated 3 months earlier. Subaru flushed the system and added 'special coolant lubricant'. This was worthless. I was told it would cost $2000+, even though my family has purchased 4 Subaru's from the same dealer. After a lot of screaming and yelling, they replaced both gaskets, radiator, thermostat and water pump. I ended up paying $250. …”

NHTSA complaint #10279775, filed 2009-08, 38,000 miles

“In october 2003, the engine of my 1999 Subaru Outback with 80,000 miles overheated, seized and required replacement. I was on the highway at the time and realized the car was losing power and the thermostat gauge was above h . I contacted Subaru prior to the repair and was told that the problem was likely due to improper maintenance and besides, my vehicle was out of warranty. This was Subaru's response even though I regularly maintain my car. I did get the engine replaced at significant out-of-pocket expense. …”

NHTSA complaint #10151257, filed 2006-02, 113,000 miles

“The 1999 Subaru Outback is equipped with a dual overhead cam engine. The timing belt pulley for the cams are made of plastic. My wife and 2 year old daughter had just exited interstate 20 near atlanta when the engine sounded like an explosion according to my wife. The engine immediately lost all power and seized, and she had difficulty steering and stopping the car without power steering and brakes. The vehicle was towed to the local dealer and it was discovered that the right cam pulley (plastic) had shattered causing the engine to seize. …”

NHTSA complaint #10147068, filed 2006-01, 110,000 miles

“I had just paid approx. $450 for the major 90,000 mile dealer service and they told me my vehicle is in great shape. I've maintained it religiously. I had an extended warranty of 6 years/100,000 miles that just ended sep. '04. I just drove it up to the mountains and 90 miles from my destination, with the car driving perfectly, I noticed the temp. Gauge was spiked. Ultimately it turned out that the head gasket went. I have 91,000 miles on my Subaru. I spoke to numerous garages in mammoth lakes and they see this problem on a daily basis. …”
