Taycan Brake Failure

[stichill99]

I was speaking with a friend who had a Taycan and while travelling at 70mph had complete brake failure which almost caused a serious accident. Porsche offcourse had never heard of this before but did eventually concede a component failure had been the cause. Taycan now gone at huge depreciation as his wife refused to drive it again! Anyone else had issues?

I had issues where I pressed the brake and only got the regen breaking, then the next time the calipers and the regen. This was ridiculously disconcerting as you didn't know what brake pressure you were going to get. At one point somebody pulled out in front of my, I jumped on the brakes and they barely worked, nearly ran into the back of the car. My son was in the car and couldn't believe how far we travelled before we stopped. Spoke to the dealer and was told that was a common issue!! Got rid.

Had similar on a 911, the brake fluid was defective as in not enough of it, top quality OPC servicing. Looks like you got the new and improved version, no servicing required.

You need to report this to DVSA as it is a serious safety failure.

The braking in my Taycan Sport Turismo was inconsistent; sometimes you got everything, other times only regen etc. and it wasn't necessarily dependent upon brake pedal pressure. it was disconcerting to say the least.

The car has gone and been replaced with an e-hybrid Cayenne, which has been faultless and is the perfect blend of electricity and ICE as far as I am concerned.

A fault that causes a leak of hydraulic fluid but cars remain safe to drive.

They must think their customers are stupid.

Isn't that the sort of thing that creates those class action lawsuits in the US. The ones the manufacturers are actually scared of. Not that UK customers will reap any benefit.

I haven’t had a letter yet, so maybe I should write to Autocar?!

It’s a brake hose, so anyone who’s bought a Porsche since 2020 should watch out then. Even a 992 ST or 991.2 Speedster etc will be fitted with crappy peripheral parts that are shared with a Skoda or Seat. Luckily these cars are never really driven so the drivers should be safe.

I’ve just had the letter so suggest you contact your local dealer and just book it in, it’s a serious fault. My brakes have been fine since they changed the actuator under warranty a year or so back, prior to that the pedal was very soft and performance inconsistent.

I’d recommend anyone who has concerns about braking performance to speak to their dealer, the actuator update seems to have been haphazard.

Out of interest, how did the pedal feel after the actuator change?

I had issues with my brakes back in Jan/Feb where the pedal was getting longer and the car felt like it wouldn't stop when coming to a halt. It always did, but only just.

They changed the fluid and bled the brakes as part of a campaign on the brakes. It was better, and at first never felt it wouldn't stop. But recently it's started to feel like it goes long again.

Got the brake hose recall letter today so will get it booked in for that. But not really sure what "good" should feel like (Will try and get a Taycan GTS loaner to see how it compares).

Hi Murph, after the actuator update it was night and day, consistent pedal feel and braking performance, it was carried out during an annual service but I think you’re in a later car (mine is late 2021) so maybe you don’t need it.

I have had one or two moments since when I’ve had to press harder than normal, but I’ve experienced similar in previous cars, most notably a C7 RS6 so I’m not sure this is exclusively a Taycan or EV problem.
