More strange things happening

In August 2023 I was in Italy for a business trip, in the hills nearby Porlezza. Suddenly while driving down to the city of Porlezza itself, a "ticktack" sound appeared, while driving in the corners.

First it came to my mind that maybe a stick or a leave or something similar was caught in the wheels and I did not pay too much attention to it.

The following days the sound would not vanish and about 2 years later, this is still the case.

The sound

First of all, this is not the noise caused by the Ackermann effect). Porsches have the strange behaviour that when the whell is fully turned and the tyres and not warm, there is a sound from rubbing.

That's not what I am talking about. Instead it as a coming and going "click" sound, as if something is hit by something turning. Imagine a plastic slightly bended, that you push to its extreme and the with force it gets back into its original position and hits something.

That is roughly the sound I am talking about.

It is temperature, wheel, speed and angle dependent.

Temperature dependency

Initially the sound would only manifest if it was warm weather. So I suspected something might be influenced to be more loose or might have grown due to temperature effects.

While in the beginning it was only audible at higher temperatures (above 25C), over the two years that the sound came and went, it also appeared at all temperatures between 0C and 35C.

Wheel dependency

Initially only the bigger summer wheels would cause this noise. Later in 2024, the winter tyres (different rimms, different tyres) would also start to make the same sound.

Speed and angle dependency

Now this is a simple one. The faster you go, the stronger the angle is, the louder the sound is. If I drive straight on a parking lot, there is no sound. If I drive left or right on parking lot, the sounds is there.

If I exit a highway (long fast corner), the sounds is very loud.

Repair tries

Since 2023-08-20 the Porsche Center OZS has been repairing this and took various approaches:

• Change wheels - to ensure it's not a problem in the wheels. Initially and strangely this helped when switching from summer to winter tyres. Later to be happening on any wheel.
• Disassemble the summer wheels - the wheels have covers, which can accumulate dirt and according to the Porsche center it is possible that dirty causes that sound
• Disassemble the brakes - as well as the wheels, the brakes can also collect dirt and again, same story, are potentially making the sound. So in June 2025 the brakes were cleaned.

Full History

This is a very particular issue, because the failure started on 2023-08-20 and has not been fixed as of 2025-05-24.

In 2023 when the problem first appeared, the car was on summer tyres. After several tests the Porsche center concluded that the problem must be dirt below the cover of the wheels, because the wheels of the Taycan have covers to make it more aerodynamic. Great stuff in theory.

The Porsche center disassembled the front wheels, cleaned them, put them back together and send me a bill of about 2000 CHF. A few days later, the sound reappeared.

Unfortunately I had to change to winter tyres soon after, which are are smaller wheels (20" instead of 21"). During the winter the sound was gone, so the Porsche repair center reasoned it must have been the summer wheels. My assumption was that something of the wheels is actually touching other car parts. My assumption has not been rebutted yet, however the one of the Porsche repair center has been:

After several repair tries in 2024, a replacement of the front wheels, the winter season of 2024 started. And interestlingly, the sound did reappear with the winter tyres now as well.

After switching to summer tyres in 2025, the sound was gone for a few days, just to reappear. As of writing this article on 2025-05-24, the car is again back in the repair center.

A bit more background to the sound: it sounds like a ticktack with something stopping (like a plastic), being bended and then popping out to make a sound. Almost like an unpleasant instrument. When you drive down the mountains of Switzerland and you drive through 180 degree corners, it as very loud, even louder than regular radio music.

It is also audible at low speed when the steering wheel is fully turned or when one leaves the highway and the highway exit is a corner. So essentially one car hear it at a speed of somewhere around 5 km/h up to somewhere around 100 km/h.

Someone suggested this might be a (known) problem of Porsche ceramic brakes, but this theory was rebutted by the Porsche repair center.

As of today, the Porsche repair center did actually clean the brakes and says it has been fixed.

Current state

After the brake cleaning in June 2025, I did not have the possiblity to drive the car again, I will report back back here in July 2025.

Review

So many things wrong and so much effort. It is for me hard to believe how difficult it seems to fix such a simple problem.
