Example complaints

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

“Car began 'stumbling' at 3k RPM under very light load/throttle. Had substantially less power at highway speeds. Small trace of white smoke during startup, only happened once. Compression/leakdown results; cyl1 = 115 / 10%, cyl2 = 125 / 10%, cyl3 = 117 / 18%, cyl4 = 100 / 23%. Driving habits are mild, I-mode 90% of the time, shifting at 2800-3200 RPM... Car is currently at dealer, they have confirmed an issue and we're awaiting response from Subaru of america on whether or not this will be warrantied.”

NHTSA complaint #10448881, filed 2012-02, 32,000 miles

“2008 Subaru wrx manual trans. 22,500 miles. Between the time the engine comes off high idle (after being started cold) and when it is completely warmed up, the engine will drop its RPM to 0 causing an engine stall when the clutch is depressed in order to change gears. This recently happened when entering a roundabout when I was going to shift down from 3rd to 2nd gear. At this point I only have my left hand on the steering wheel and right on the shift lever. The engine stalls and I loose power steering. …”

NHTSA complaint #10306023, filed 2010-02, 15,000 miles

“I started to get a film on the windshield of my 2008 Subaru. I took it into the dealership and they did a test and found a problem with the A/C unit; they told me the film on the windshield was safe and car was safe to drive. I took the car in again while they were waiting for parts, for another issue, and I requested a copy of the tech notes and the film that was on the windshield was freon!- health hazard. They fixed this problem with the freon film, and now not a month later its back, and worse. …”

“I own a 2008 Subaru Impreza sti which I purchased in feb. Of 08'. 2 months ago the car went into limp mode when I was driving home. I took it to the dealership to have it checked and they said it only had 1 1/2 quarts of oil in it. I had checked the oil the previous week and it had shown full. They requested that I give them record of my previous oil change so I did. Unfortunately, it did not have mileage documented because it was a small shop that did it for me. They refused my claim on the grounds that I did not maintain the car. …”

NHTSA complaint #10241388, filed 2008-09, 13,000 miles

“Smoke coming from the exhaust, rough idle, oil consumption were my first signs. The dealer wouldn't do a compression check on the motor since there was no check engine light on, so I had to pay with my own cash and take it to a private shop and found out that in fact cylinder #2 had a shot ringland. They replaced the piston but the motor doesn't seem to be right still since I have a car that was involved in a stop sale that involved some engines having some debris in the motor and was causing knocking and throwing bearings. Subaru should have replaced the short block but didn't.”
