Just jump started 2019 Cayenne

Now getting these errors


Vehicle electrical system error

Engine run required for electricity
Vehicle system error

Electric parking brake error

Drive distribution system failure

What should I do?

Will these errors go away after car gets fully charged?

I left the car running so it charges

it was completely dead

 

I don't believe those errors are going to go away on a 2019 with the LiPo battery. More that likely the module on the side of the battery has gone bad and you will now need a new $2300 battery according PCA. Read over the 2019 Battery sticky at the top to see your different options.

 

I did not drive the car for 4 months so battery died.

so we jumped it and now got these errors.

so am thinking once it’s fully charged, errors should go away.

I doubt battery gone bad just because we let the car sit for 4 months.

You telling me if we go on vacation and come back we need a new battery that cost $2300 each time.

If that’s the case I will be going to Porsche headquarters

 

Charge your car with the charger. Once the battery is charged, lock it with the key and leave it for 15-20 minutes. After that, check if you still have errors. Various errors may occur when the battery is discharged.

 

It is possible that all those errors are due to low battery voltage. Try to charge it fully and see if they go away. It is also possible that due to the depth of discharge the LiPOS battery in your car is damaged and will have to be replaced. If you are going to go away for more than a couple of weeks then it is good practice to hook up a trickle charger. Porsche warranty on the battery is void if the vehicle isn't driven more than 6000 miles per year and not trickle charged (this part is in the manual). And yes it sucks and is stupid. There is a mountain of threads on the topic of this LiPOS battery here. Even if you do everything right and drive the car and trickle charge when not in use there is a good chance the battery will fail in a few years. Plenty of people have complained to Porsche.

 

I experienced a discharge on my 2019 recently when a maintainer lost power due ro plug being disconnected by a family memeber while I was recovering from hip surgery. Jump started it and got check engine light. Hooked up a battery maintainer until battery was fully charged. Started the vehicle and check engine light is off. So, try that. Also, I’m not sure, but I think there is a protection shut off circuit for the battery that keeps it getting to a fully discharge state causing permanent damage. If so, your battery should be ok.

 

Will my battery fully charge by leaving the car on and letting the engine run on idle?

How long will it take for full charge if I just let it run while parked?

The warning lights say stop and park it safely…or something like that…so I did not drive it yet

just letting it run while parked

 

It’s a 2019 so will the battery still be under Porsche warranty?

 

It is best to charge the battery with a charger. If you want to charge it by leaving the car idling, the charging process will be long and it is also not good for the engine.
If you don't have a charger, just get in your car and drive it for 100 miles.

 

If the check engine light is not flashing, you are ok to drive. If you did not have a check engine light before this, then once charged to an acceptable level (>~75%), the warning lights will most likely go away on restart. Retom's recommendation on using a charger/maintainer and or driving is a good one.

 

Car should always be put on a trickle charger if not driven for more than 2-weeks.

 

Wasted 2 hours letting the car run idle thinking it’s going to charge the battery.

once I shut the car off, and tried to turn it on, it didn’t start…completely dead

now what???

should I get a trickle charger…what kind?
don’t know anything about trickle chargers
Can I get it at Walmart?

Do I plug it in the front or under the passenger seat battery?

thank you all for helping

 

Which trickle charger should I get from this Walmart?
