I'm honestly getting tired of calling around and getting vague answers every single time. My 2017 Cadillac XTS started giving me trouble last week, where the engine cranks really slow in the morning but after a short drive it seems fine again. A friend told me the heat here kills batteries faster than anywhere else and I should just replace it before I get stranded. The problem is every shop I talk to gives me a different price and a different brand recommendation, and I have no idea who actually knows what they're doing with Cadillacs. I don't want to end up with some cheap battery that dies after three months or worse, one that causes electrical gremlins because the car's computer doesn't recognize it. Has anyone here gone through this and found a place that actually understands these cars? I'm looking for Cadillac battery replacement experts Dubai who won't overcharge me but also won't mess up the installation. My XTS has all sorts of electronic features and I've read that some cars need the battery registered after installation otherwise the charging system gets confused. Is that true for Cadillac as well or is that just a European car thing? Also what brand should I be asking for? Should I stick with AC Delco or is there a good aftermarket option that survives the summer heat without swelling up? Really need some solid advice before I make a decision because right now I'm just driving around nervous every time I start the car. Appreciate any help from people who've been through this already.
