Any battery can be a good battery. The Walmart battery is an excellent battery at a good price. Know that Walmart does not manufacture batteries and it is made by one of the 4 manufactures in the U.S. The best battery would be an Optima but they are pricey.

Same way you do for every other car.

Have it checked for codes. There has to be a reason that the computers are limiting you to that speed.

You have to remove the taillight assembly. When you open the lift gate there is 2 push clips (black round) that keep it in place. To remove the clips, you have to pull sort of hard. Then slide the taillight out of the slot that it clips into. Don't be afraid to pull the taillight, it's in there pretty tight even after the clips are removed. Twist the light bulb that needs replacing to the left and insert your new bulb.
