Default 992 Jumpstart Issue

Merry Christmas Eve All,

Forgive me if this is a topic that has been addressed recently, as it has been a while since I was on the forum. My 992 turbo s has sat largely doormat for the last 7 weeks (less two start ups) due to an ankle surgery on my right leg that has prohibited my driving. I started the car on Wednesday for 5 minutes and now the car won't start, nor will the frunk release to allow access to the battery. I have opened the fuse panel, pulled out the retractable charger prong, and have connected both a jumpstart pack as well as jumper cables from my wife's vehicle to mine with no success. Has anyone on the forum had this issue before?

this thread has quite a bit of info

sounds like your car is parked in a safe place so give the dealer a call and see about replacing the battery

once done get a trickle charger

this is especially critical if you have the lithium battery

Plan on calling Tuesday. I should also add, when I have the cables connected, the rear light bar a brake lights flash, but interesting not all of them. It's one brake light and half the light bar on the opposite side.

Im not an expert on exactly whats happening relative to what you describe but I have heard the system is a bit sensitive so if I were you I would wait and let the tech guide you. Maybe some folks on here know

obviously it makes it easier if it is safe at home and you do not need to drive it

Try opening the trunk with the key while the jump connections have been made. Also make sure you have a good ground for the negative cable. Try a few different spots.

Since his car is relatively new, can’t he just recondition the battery? Does he necessarily need a new one?

Once you connect the red tab to the jump pack, use your KEY FOB frunk release button, not the one on driver’s door sill. It needs to be on your key fob.

earlier models 2021/22 had a defective ground cable strap where it connects to the chassis - be sure to inquire about it....although it is an official recall so it should be taken care of at your next dealer visit

i found out the hard way (had to be towed to the shop because it wouldn't start)...but initial signs that it was going to be a problem were the lights started going whacky, and the lights on the console were not consistent

Using the Key Fob versus the manual release did the trick. Thanks again and Happy Holidays!
