What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I was parking at the dentist office in their parking lot going slow, turned into a parking space and thought i was slowly braking but my car lunged forward and hit a tree. I would normally be minimally braking, so I'm not sure what happened but it was sudden. I could have hit the gas pedal but i would have pressed it a lot I think for the sudden lunge to happen.”

“I was pulling into a parking spot almost stopped when the vehicle suddenly surged forward. I slammed on the brake and put the car in reverse since it had driven upon the walkway. This happened earlier today and I plan to have it checked out as soon as possible . Never have had this problem before, no warning lights or messages.”

“This has now happened twice to my daughter, both times on the highway. One time the car shut down completely and the 2nd time the car just started slowing while pressing the gas and coasted to a stop. Luckily she was able to avoid other cars and get to the shoulder. The car restarted both times...1st time after about an hour wait and 2nd time within minutes. Both incidents happened when the gas gauge was at 2 bars. I am terrified of this thing right now. No warning signs at all prior to the incident. I took it to the dealer after the first incident but they could not figure out what the problem was as they were not able to recreate the issue. This is an extremely unsafe issue and I am not sure what I should do next.”

“On 3 different occasions the car randomly accelerated at a high speed without stepping on the gas pedal. The first time was in a parking lot. The second time was on a busy road while traveling at 35 mph. The car accelerated to about 60 mph, fortunately once applying the brakes the vehicle slowed down to gain control. The third time it happened was recently on [XXX] while slowly backing down [XXX]. The car accelerated backwards at a very high speed narrowly missing a fence in the neighbors yard. These incidents have happened with large time frame gaps in between the occurrences. After the third incident I took the car to a dealer Planet Subaru in Hanover MA. After keeping the car for a few days, the dealer called and said that they could not find anything wrong with the car and there was nothing that they could do for me. This issue is obviously very serious, if the car surges forward randomly while someone is crossing in a crosswalk it could be potentially fatal.”

“Retailer failed VSI due to a defective cracked catalytic converter under warranty. Part is still in use because retailer refuses to service vehicle forcing me to operate my unsafe vehicle endangering myself and family including my then [XXX] son. Dealer confirmed defect and warranty coverage yet still refuses to address the issue. The vehicle has become notably louder as a result of the exhaust leak.”

“Oil consumption issue starting within the first 3 years of owning the vehicle. Oil light comes on generally after driving 2,000 miles or less from the last oil change or oil fill up, but prior to the light turning on there are acceleration issues. Vehicle bucks and lunges when accelerating. Lunging seems to occur after vehicle seems to loose power to accelerate and then lunges forward shuddering as power returns. These issue worsen after oil light has come on. Vehicle feels very unsafe when trying to merge if acceleration is needed. Also almost hit from behind when car seems to lose power when trying to accelerate after stopping for a red light. Vehicle has been serviced repeatedly at dealership and oil consumption issues documented. Vehicle’s make/model with known oil consumption issues, but this vehicles VIN has not been included in recalls.”
