Vehicle began surging during acceleration. Dealer stated that the engine intake valves had carbon deposits that were causing performance issues including poor fuel economy, increased emissions and running concerns. The valves required a cleaning to correct the issue. This is a 4 year old vehicle with only 38,000 miles, this is unacceptable for issues like this so soon. Estimated cleaning cost is $300 and is mentioned no where in the scheduled maintenance information.
Once or twice a day my vehicle hesitates from a light and I have to almost floor it to get it going again. I have brought it to 2 different Subaru dealers 3 times and they say they can't fix the problem.
Vehicle was parked and idling unoccupied for under 5 minutes when an extremely noxious, hot blast of fumes came from underneath the back. Black smoke immediately entered the passenger cabin through the vents and flames were visible in the engine compartment and running onto the ground. Entire vehicle was burned beyond recognition in a matter of minutes. Ten days earlier the tcv, a known problem, had been replaced at a dealership per TSB 09-80-21. The vehicle had been driven under 300 miles since the replacement. Afterwards, a manufacturer rep inspected the vehicle, indicated the fire started in right rear of the engine compartment, could have possibly been a fuel leak, but damage was too extensive to determine the exact cause. The referenced TSB explicitly requires a new fuel line for every tcv replacement.
I was coming out of my garaged ( car was facing forward) . The car seemed to hesitate as I tapped the gas pedal. I thought maybe this was because the car sensed the sides of the garage via the rear view mirror sensors. I am always careful when exiting my garage so as not to ding the rearview mirrors. I repeatedly tapped the gas lightly about three times but the car hesitated each time and did not want to seem to move forward. One last time I tapped the gas and the car bolted out of the garage jumped the curb across the street at an unexpected rapid speed. I did not have my foot on the gas pedal. The car lunged forward , crossed the street and hit the garage door and frame of the house across the street for me doing structural damage. I believe this to be unintended acceleration for which other Subaru models have experienced problems. The air bags did not deploy. . Read more...
This is for a car only 18 days driven. Windshield cracked from bottom, under retaining gasket, with no strike, impact, or previous ding. Car hood flexes up and down, more than 2-inches, when large trucks pass in opposite direction. Automatic fuel stop at pump did not work properly, causing fuel spill one time, and underfill another time. Windshield visibility and possibility of total failure. Car hood could fly up and obscure visibility and break windshield. Have not contacted dealer or insurance company yet about issues. Windshield problem is a known defect for Subaru, and subject of many lawsuits. No warnings before problems.
