HELP First time WRX owner - Valve adjustment needed at 50k miles??
First post, and really in need of some help here.
I purchased my 2013 WRX hatchback new and absolutely love it. Haven't had an issue with the car until about 3 days ago.
Brought it into the dealership for it's last covered service, the car just reached 50k miles. About 3 days before I brought it in, the CEL, traction control, and cruise control lights all came on. (No, the gas cap was not loose.) When I brought the car in for the service, they checked it out and told me this:
P0300 code - Random misfire detected in cylinders #1, #2, #4
Inspected the spark plugs and they are OK
Ignition system is working properly.
Recommend performing engine valve adjustment and inspections $4500, not covered by powertrain warranty
1) wtf? I drive this thing conservatively. I don't red line it, ever. I usually always even shift before 4k rpm. Is this a common issue at 50k miles?
2) $4500 seems waaaaaayyyy excessive for this job. I called other Subaru dealers in the area and got quotes ranging from $840 (just labor, not including part cost) to $1200 (includes labor and gaskets, no shims). comparing that to my initial quote from the dealer that I bought the car from again, wtf? $4500? I feel like this guy is trying to rip me off, more than 2x the cost of other nearby Subaru dealers
I know dealerships are always way expensive, but I figured I'd get the work done there until the powertrain warranty was up (10k more miles) incase something major went wrong.
The only thing I've noticed in performance, is that when the car is hot (after commute home) and I'm in the process of pulling into the garage, I put it in gear, slowly pull in, and when I press the clutch and stop the car, the idle dips really low
Any and all information shared would be a huge help! Thank you!
