Could be a few things assuming you have the i6 engine. Check your plugs, and coils. Did it recently rain? Our hood seals at fire wall are faulty, will leak water into cylinders 4 through 6. Check each cylinder with a mirror, make sure no water. I use a long screwdriver with a rag or paper towel to get in there an soak it up, prior to plug removal.
