I just took my 2019 2.0L Turbo in for a recommended spark plug change at 30,000 miles. The dealer said FCA changed the interval on that engine to 60,000 miles, so I didn't have them changed. I also can't find the plugs for this engine anywhere; Autozone, RockAuto, O'reilley's, NAPA or Advanced Auto Parts. They simply don't list them. The Jeep dealers have to order them by VIN and charge about $22 apiece. Anyone know why this is such an issue?
