Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“As soon as the car aged to 75,000 miles I started having problems. The closest Subaru dealer is 51 miles away from my current location. Not easy to get to. My in town mechanic has only been trying to treat the symptoms. I've had thermostat, heater core, valve covers, spark plug wires replaced, hoses replaced, and still has not fixed the issue. I took it to a Subaru dealer this morning, still overheating, and he says I have a blown head gasket and I will have to replace valve covers, wires, obviously the head gasket and possibly a few other parts. Labor alone is a 1000 dollars. …”

“Exhaust fumes some co poisoning symptoms 2001 Subaru Forester posted by dave on february 08, 03 at 06:52:29: I fueled my Forester with 91 octane premium fuel and took off on a 5 hr drive to denver. There were extreme driving conditions 40 MPH winds and ground blizzards. Set the cruise control at 75 MPH and it was all the car could do to maintain 70 MPH in high gear and on some hills it would downshift to a lower gear to satisfy the computer setting of 75. After 2+ hours of driving I noticed a strong smell of exhaust fumes. I developed a headache. …”

NHTSA complaint #10005513, filed 2003-02, 37,200 miles

“At about 25,000 miles my 2001 Forester stalled 3 times in my driveway and shook a bit. I had the idiot-new-owner-package with the dealer where they did all the maintenance, etc. And was scheduled for an oil change/whatever maintenance anyway so I asked them to check it out. They could not reproduce the problem and it did not happen again to me until several months later. Now at 38,000 miles (3000 miles after warranty and after the end of the idiot-package) it happened again. This time it stalled on several occasions both in parking lots and at stop lights. …”

NHTSA complaint #10010599, filed 2003-03, 38,000 miles

“Blown head gaskets, cracked short block, and o2 sensors all replaced at around 100,000 miles. O2 sensors replaced twice. Unknown when problem first occurred and which was cause and which effect. Head gaskets should be covered by program wwp-99, but Subaru will not consider nor discuss any accommodation.”

NHTSA complaint #10172101, filed 2006-10, 100,000 miles

“Recall ww-99 was issued by the manufacturer that was not found at this time. There was external coolant leak into the head gasket, which could cause the vehicle to overheat. Dealer was only flushing the system, and was unable to remedy the problem. Also, yokohama tires that were under the proper inflation for the vehicle caused it to slip and slide even though it was all wheel drive.”
