It started with a ticking noise and when I took it for service they said that it was my lifters and to replace them it would cost 5-6 thousand, and that I might as well replace the engine. I later find out that this is common with all the 07 but the manufactory want recall or assist with replacement cost.

Vehicle used way too much oil. Oil consumption was extreme. Began to hear a ticking sound, while driving on expressway the lite up like a christmas tree. And smoke began to billow out the exhaust. Took it to dealer said I needed a new engine. Reading posts on line everyone is complaining of same issue. This should be remedied by manufacturer. Now car is sitting waiting to get an engine.
