When the check engine light I was not really concerned, Now it is in the shop and the service mgr. did not sound confident in the repair. Said it would be a few days??? A cam sensor issue. I was told the intake needed to be removed to access the cam sensor and removing shims to order the correct replacement shim. Then I started researching online and read all about these related cam problems including head,cam and entire engine block replacement. WTF only 3000 miles (not driving in snow)
