The problem: Drivers may notice engine misfire and smoke coming from the tailpipe upon startup, acceleration or deceleration. Additionally, the engine may run rough and consume excessive amounts of engine oil. These conditions have been attributed to leaking valve stem seals. When these seals leak, they foul the spark plugs, causing these symptoms.

Corrective action: Dealers will replace the valve stem seals.

Warranty info: This repair is being covered under the new-car or extended warranty, whichever is applicable.
