Hi everyone, just took my 2017 Crosstrek CVT in to the dealer for the 30k recommended maintenance. Oil change, brake flush, fuel flush, throttle cleaning... Car has always run well. Got it home okay. Next day the car started rough but got me to work and back. The following day I had a really hard time starting the car, got to work, had a hard time starting after work and then car was sputtering and jerking when I let off the accelerator. No problem during acceleration. Parked the car and it started pinging and rattling like crazy. Turned it off and restarted with hood open. Pinging, squealing and a strange recurring swishing sound. No smoke, steam, dashboard lights. Called Subaru immediately and said I didn't think the car should be driven as one of the sounds seemed like valves. They told me that was typical if the computer didn't reset correctly. 2 days later? They asked that I drive it in-45 min away. Switched it out for a loaner. They're telling me that the throttle body is stuck open after repeated cleanings and that they are assessing the engine for damage after replacing the spark plugs. They asked me if I put gas in after the service. Nope-filled up 1 wk prior at Exxon. No update yet but not a good first Subaru experience. Will see what they have to say today or tomorrow. If they can provide a sufficient explanation and replace everything harmed, I may just ask them to extend the warranty. Anybody else have this type of experience?
