Hey guys and gals,

So yesterday my car started flashing the hazards about 20 seconds after locking the car. I don't know how long it goes but after a few minutes, I press the unlock button and it stops. But then the car re-arms after a few minutes and it starts again.

I have looked through a bunch of Porsche posts (not even specific to 958) and some actually have said it's the cars way of saying the electrical charge is low and may need a new battery. I fail to see how that would ever be engineered into the car. Plus, voltage has been normal as it's always been.

Some other posts say it may be a fault in the alarm module and it needs to be replaced. I don't have a real diagnostic tool but do have Blue Driver. I scanned the car and I get no codes.

Has anyone else had (or read about) a problem like this?

If I can't figure this out, I'll drop it off at the dealer this weekend..but figured I'd check here first.

TIA!

Year?

Batteries degrade over time, some folks get longer life out of them than others, but 3-5 years is not an unusual frequency for changing them.

One quick check would be to put a battery charger on it when you park it and see if the situation changes. If so then it'd seem like a battery replacement is in order.

Just updating for those who have this issue in the future.

Took her into the dealer and evidently the issue was a faulty (non working) alarm horn. They replaced it a few weeks ago and all seems to be back to normal.

Thanks for updating the thread! It's good when a thread has a "solution" to a problem.
