Example complaints

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

“The speedometer on my 1999 Subaru Legacy l sedan stops working at random intervals. My mechanic tells me that this is connected to the also faulty transmission and is not just a minor speed sensor problem. Subaru denies any knowledge of these problems but I have researched and found many, many 1999 Subaru owners with the exact same problems. The 1999's had a new transmission that is very flawed and was changed again before the 2000 release because of so many problems. …”

“This car accelerated suddenly and spontaneously while I was shifting from reverse to drive;the brakes had no effect in slowing the car down and I had to crash into a concrete post to stop the car and avoid hitting other cars and pedestrians. The car is totaled and I am lucky to have survived.”

NHTSA complaint #724364, filed 2000-06

“On two consecutive days, 4/15 and 4/16, while stopping from a <5 MPH speed, the car surged ahead 2-4 feet, stopped, and immediately surged ahead 2-4 feet again, and stopped. The first time it almost put me out in heavy traffic on a 4 laned highway. The second time I was pulling into my daughter's driveway and was stopping when it surged ahead taking out the post supporting their front porch, stopped, then immediately surged ahead taking out the lattice work under their porch. Both times the car was on an uphill incline. …”

“Cruise control was engaged as I was driving on the highway. When I applied the brakes approaching the exit ramp the cruise control did not seem to disengage. While my foot was on the brake pedal, I hit the cruise control switch on the dashboard--the cruise control light went off, however the car did not slow down although I was applying the brakes as hard as possible. I lost control of the vehicle and hit a tree head on at an estimated speed of 40-50mph. Neither driver nor passenger airbag deployed. The vehicle was a total loss. I contacted Subaru of america, inc. …”

NHTSA complaint #704070, filed 1999-03

“While accelerating away from a stop, at low engine RPM and low throttle opening, the car hesitates. If you give it more throttle, it gives a sudden but unpredictable burst of acceleration. It is very difficult to get out of the way if someone happens to be headed toward you. It is also impossible to know when the car will start to accerlerate normally. It is a jerky type of action that does not coincide with the smooth application of the accelerator pedal.”
