Your reply is greatly appreciated.
1. where is the battery location?
2. OEM or costco battery or?
3. Is it a straight fwd battery replacement, just like any other simple cars?
4. Do I expect any faults?

Because I use the 12v inflator to add air on all 4 tires. I feel the battery is kinda weak,
whenever I started the car. That is the reason i am thinking of replacing the battery.
Any recommendations are appreciated. Thanks in advance.

My battery just died - would also love to know the above information - can you just grab a battery at CostCo, or do you need to take it in?

I had the same problem on my 2009 not too long ago. I went to the dealership and bought a battery there probably for either the same price as the auto store if not cheaper. I think I paid around $175 for it.

1. where is the battery location? Battery is located in the engine bay on the passenger side of car, near the windshield. There is a black bulky air filter cover, undo the 3 clips holding it in place and remove the cover, and you'll see the battery.

2. OEM or costco battery or? It should be all the same, just whichever is easier for you.

3. Is it a straight fwd battery replacement, just like any other simple cars? I saw the MB roadside assistance come change mine this April. When she changed mine, the process looked very straight forward, just like any other car.

4. Do I expect any faults? If you're using the same battery since 2008, it's probably time to change your battery. My batteries typically lasts me 4 years.
