27280 mi Now told vibration is normal due to running a lean mixture during warm-up to prevent carbon build-up.

This RB Accent tends to develop a Pinging issue in some cars, I just happen to have one of those cars. If you run 91 Octane or Higher it no longer has this issue. Hyundai has a recall in this issue, but states that is does not affect my car.

45880 mi Gas cap light continued to turn on and off intermittently. Dealer replaced vent valve under warranty. Issue has not returned in 3 weeks since. 
68180 mi Check engine light on again. Code indicated knocking, a known issue with an available ECU update, which was performed. 
77064 mi Check engine light on again. Diagnosed as a faulty purge valve, which was replaced under warranty for a second time. 
80665 mi Check engine light on again; "resolved" by clearing water from evap line. Was charged a diagnostic fee despite car being under warranty; apparently Hyundai warranties only cover labor when it's to replace parts, and no parts needed to be replaced. Dealer provided no answer as to how water got into the fuel system or what they had done to prevent the issue from reoccurring. CEL came back on within 48hrs of previous visit. Dealer ordered replacement charcoal canister, took 2 weeks to arrive. Charcoal canister replaced under warranty.
