Just hit 20,000 and car was sluggish then the check engine light came on. One week left on factory warranty
dealership replaced fuel pump and manifold major carbon buildup.
Check Engine light returned fault code for Fuel System. Replaced gas cap initially, but Check Engine light went on again. Smoke test found leak from fuel vent valve, which is part of leak detection pump. So replaced leak detection pump, but Check Engine light in on again after a few days.
In the shop now...under warranty...except now they say I need a waterpump....dealerships are not to be trusted...still waiting to speak with the service manager.
