So it finally happened , I have my first GTS electrical issue that happened tonight unfortunately away from my house 😭. So looking for ideas on what to check out tomorrow before I pay for a tow truck to drop it back at home. as far as bad news goes it is stuck parked at the top empty floor of my local restaurants parking garage so it’s fine for tonight as I don’t think it’ll be impounded/ticket towed
anyway the basics is it’s been cold here (45 degrees) all week so I didn’t turn the Car on since last weekend.
Tonight I go to the car, doors open fine with key I sit down turn the key to on position and
no noises/clicks (no crank ) i don’t hear any relays and starter not engaged, car doesn’t even attempt to crank.
All lights work in the inside and no flickering or error lights aside from the ones that always show before you start the car. I have the digital dash so it shows 11.4-11.7 voltage for battery. I close my car door take the key out lock the car unlock the car open door put the key in turn it on etc basically do this like 4/5 times and it finally starts after 5 mins of trying these random combos . no error lights on Dash and no engine noises or issues entire 25 min drive and while driving battery voltage shows as 13.5-13.6. Park in parking spot and let car idle an extra 5 mins before turning off.
go to eat for 2 hours and come back and now same exact issue. Can unlock door all lights work no flickering but when you move to ON position car doesnt crank , seems like a relay issue. Battery voltage shows as 11.3-11.6. I disconnect negative battery terminal let sit for 5-10 mins then still no difference. Then I think since it won’t even crank maybe it’s a key immobilizer issue so my friend and I go to a grocery store and buy new key battery.Go back to car still no difference
Anyone know what ignition or crank relays or things I can check when I go back to the car tomorrow ?
Battery is from 2020 so not super old and it has drained once but those symptoms were very obvious like the key getting stuck in ignition and the dash having all these error codes and the typical starter clicks . My issue it won’t even crank.
I will also be bringing a few tools so I can actually unbolt positive terminal also so battery is completely disconnected.
