I drive an 08 that I bought new and have just experienced a new problem that others might profit from reading about. Went to start the car early yesterday morning, temperature in the garage about 25 degrees. Didn't start. Tried it again and it tried to start and sounded like there was no compression on at least l cylinder and maybe two. After multiple attempts, it finally started, ran on 1 cylinder for awhile and eventually another cylinder kicked in. Shut it off and took the truck for the errand I needed to do, while going through the possibilities of what might be wrong. Remembered that it was last driven by my grandaughter, so immediately feared the worst....did it overheat and she didn't notice??? Got home and checked coolant level....right on the mark, so that was one big worry gone. Back to reviewing possibilities. Happened to think that this was the coldest morning we've had this year. Checed the temperature in the garage and it was now 38 degrees. Tried starting and it started, sputtered once, then ran normally. Clonclusion....some water in my last tank of gas and it froze at the injectors, or the individual lines leading to them.. Put in some Heet and took a test drive and everytrhing was normal.
