Porsche Cayenne all systems faul

[Masliantchouk]

Hello. Looking for some advice as to what might be the problem with my dad's Cayenne. He recently drove to FLA with a fully loaded car. The trip was smooth, but on the second day after arrival, many faults popped up. ABC fault, PCM fault, chassis system fault, all wheel drive system fault, electric parking system fault, steering wheels system all the same time. The car still drives fine, for now, but it is alarming to have so many faults. He's been to autozone, but their diagnostic tool failed to show any cause for this. Any guesses at what this may be are greatly appreciated, before he'll have to go and unload some Benjamin's at the dealership. Thanks

How old is the battery?

[Masliantchouk]

The battery is original one, from 2012

May be time for a new one. P-cars get weird when the battery is on it's last legs. Can be done at ome but it is a pain. Head over to rennlist.com Cayenne forums or see if the procedure is listed here

Thanks. I will check it out. Is there a way to check the status of the battery? How well it works/charges the car?

Recommend Autozone, Sears, ***Free Alternator Battery check Diagnostic.***

They can give you a print out...

Best regards.....
