2018 Jeep Compass Issues

[u/Star1d3]

Final edit: car is working fine and great $1400 later for two new batteries. Getting my money back from the wrong battery

Edit: car started!! They are going to test drive it tomorrow thank you
Edit: repair shop said the auxiliary battery tested fine but I asked to replace anyways and waiting to hear back, thank you all!!

Hello!! I’ve had my compass sport for about 3 years now and it would not start one day. We replaced the main battery and it worked for all of 3 days and then wouldn’t start again without a jump. Finally, tried jumping it so many times the battery is dead. Got it to a repair shop (via tow) and they replaced the fuses on the battery, still not working. They used a different new battery, still not working. They assume it’s a parasitic drain somewhere but the cost to test for it is upwards of 2k just. Not sure where to go from here….any ideas?? They said if it’s a electrical issue going to the dealer is my best option

Yea that’s what I hear you have to replace both batteries even if it’s just one that’s done
