Example complaints

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

“Shifted from park to reverse with normal brake depression; vehicle immediately accelerated to 20 MPH, no brakes and the dash control center completely lit up. The only way I was able to stop vehicle was by shifting to neutral and engaging the parking brake. I then tried the same procedure in forward with the same results except this time resulting with the car colliding with the garage wall causing approximately $6000.00 worth of damage between the car and house.”

NHTSA complaint #10629193, filed 2014-08, 105,000 miles

“The check engine light came on while driving and stayed on. That meant something was amiss with the emissions control system, probably a loose gas cap. I checked the cap, took it off and retightened it until I heard the proper clicking sound. The light remained on the rest of the trip home. Twice more before servicing, I repeated the process of checking the cap. Both times I heard the clicking sound. The light remained on. I had the problem looked at by a Subaru dealer. After 2 hours they told me I was either overfilling the tank - I never top off - or not putting the cap on properly. …”

“Vehicle: 2009 Subaru Forester limited, on 6/20/09 I experienced an incident of unintended acceleration. Cruise control was on. Before our exit I canceled the cruise control but left it on . On the ramp, I let the car slow. At about 40 MPH I moved the shift lever into 'sport' mode, downshifted to 3rd gear, then 2nd, then braked to a stop. The car was stopped, in gear, idling. My foot was on the brake. Without warning, the engine raced and the car jolted forward about a foot; it would have continued but I increased pressure on the brake and stopped the car. …”

“Traveling on an interstate at 70mph, car check engine light came on and car lost all power. Was able to limp off the road and wait 3 hours for a tow to dealership. Diagnosis; stage 4 blown head gasket. There was no prior warning or symptoms and could have been a greater danger if heavier traffic. Head gasket problems know on early model Subaru's.”

NHTSA complaint #11404303, filed 2021-03, 160,000 miles

“Gas tank corroded and is leaking gasoline. Car has not been driven off road, is regularly washed and stored in a garage when not in use. Car is 9 years old and has 105,000 miles on it. Although out of warranty, seriousness of leaking gasoline warrants a look at these tanks, are they properly rust proofed ? Tank hands down under car, rear seat area and is exposed to road salts, water and mud.”
