NHTSA Complaint #11495411 — 2019 HYUNDAI SANTA FE XL

Purchased vehicle 7/25/2022 at the end of October battery was dead we jumped it. Then when it got cold it would not start jumped it and started. Went bought a new battery the battery in car when we bought it was a 630cca parts store didn’t have a listing for my battery so matched it and got one with 640cca. Next morning would not start. Tried jumping it wouldn’t start that way. Called Hyundai parts department and asked what battery should be in it said at least 660cca, so we got a 750cca a week or 2 later Today 11/29/22 was cold snow morning wouldn’t start. The problem is my car doesn’t start below 32degrees. Very upsetting I buy a new vehicle that reliable and it doesn’t seem reliable it. I’ve also read earlier forums and I read numerous complaints about this issue. I try looking up the battery for this model and it say’s discontinued so what am I supposed to do. I need a reliable car for my family not one that will leave me stranded and calling in to work or kids to not go to school.
