Dealers here have no cars on the lots and the P8 is very rare.

Hypothetical discussion

Just had a thought, and wondering if anyone has considered this. I was talking to my wife about this issue and letting her know that one of the quirks of owning an EV (with electrically actuated parking brakes) is the need to drive it round and dry them off after washing. I was mansplaining her that unlike the XC90 you can't leave it in park (transmission park) with the parking break unused as there is no conventional transmission. It is not accommodated by Volvo, no doubt for safety reasons. Then it dawned on me that there is a scenario when you need the parking break to not be on and the car to able to move.......Towing!!!

DON'T TRY THIS!! - Discussion starter only

I looked up the owners manual and noted that:- "Tow mode is used when the vehicle needs to be able to roll freely, for example, to pull it up onto the bed of a tow truck." which deactivates the parking brake.

Once the pads and rotors are dry.
"Deactivating Tow mode

• Make sure the vehicle is stationary.

• Apply the parking brake.

• Tow mode is now deactivated."

Obviously this comes with very significant potential safety issue as 4700lbs of vehicle rolling on its own will cause significant damage and even possibly fatalities, but if the wheels were securely chocked for a couple of hours....

Anyone crazy enough to think of this idea?

I am not willing to do this. I have been determined to now have to be inconvenienced by this brake design. Either they fix it or they buy it back. Putting metallic bpads against a wet rotor is a dumb design. My car is at dealer for brakes again. I am hoping they agree to use my pads and support them via warranty. If they don;t I can either keep having them do rotors and pads every 1-2 months or they can buy it back. I may gamble on the pads either way since the car now qualifies for lemon law using their parts. At this point if my pads don't do any better they can buy it back.

Tow mode... I believe it requires the motors to be powered which will drain the HV battery a bit more than you'd expect. Also, I thought that it will automatically shut off after a certain amount of time. Something like only 30 minutes, but I can't remember.

Guess I'm crazy 'cause I tried it a couple months ago and it doesn't work, unless you want to leave the car running and drawing down the battery. The vehicle stays running while in tow mode, but I don't know if it times out after a set time or not. I tried it for about 10-15 minutes. Anyone try it for more than that?

Uh, have you been checking the Polestar forums lately?

Didn’t drive for 10 days - now it’s f***d

Went on holiday. Left car in driveway. Gone 10 days. Now back and car is knackered. Massive clunking noises as wheels rotate - feels like motor broken or wheel knackered but totally unsafe to drive. It was fine before we left.

I joined, put my story in there with a link back to here. It seems sooner or later Volvo/Polestar are going to have to address this.

This type of issues tend to end up as a service bulletin (there might be one out already) or a recall. To expedite that, everyone affected needs to contact volvo (ensure there is something on writing) and have them acknowledge they hear your complain.

Long story short, I had a mazdaspeed3 a few years ago, the car had a constant clicking coming from the windshield. It was not addressed by Mazda until multiple people started bugging them. They eventually created a service bulletin. Even with a service billeting dealers kept saying there was nothing they could do even though it stated that the windshield abs pins needed to be replaced.

I still remember very clearly when ORKA was towed from work (impossible to continue driving due to the loud clanking as the wheels were turning), and that's after 2 weeks of rolling it out of Dealership. 1 week of "fighting" with Dealer as shockingly they couldn't replicate the sound ! But after much pestering of "Do you REALLY think I want to call a tow truck to take a $60k car away if i thought it wasn't a safety issue ? And have to explain to EVERYONE why a brand new car is towed away with co-workers looking on ?" So they decided to open it up, and agreed (they even sent me pics) that the brake pads were totally ripped from the rotors....... since the rotor and pads were replaced, I haven't had the same issue.
BUT WINTER IS COMING..... we shall see !

Dealer called. Typical they will put my pads on and if it fixes it they will replace them with redesigned pads when they come out no charge. Ironically they don't want ot replace the rotors and I asked them to call regional persona nd get that approved. Told them we will know real soon if this fixes it fine I keep the car and get another one to replace her T5. If they don't then I submit car for lemon law.

 

[He Keith]

Been following tat Polestar forum now and seems a few folks there have been having same sticking brakes issue, some multiple times.

 

[SeattleCat]

Not surprising but also a mix of reassuring and depressing

I wonder what is going on with the porche ev.

 

[He Keith]

Dealer called, my car will be ready in a few hours with my pads and new rotors. So the next week or 2 should be interesting.

Would be interesting to know from the service department if it is ok to engage the P while the car is moving. When is it ok to do engage it.

Good luck. Glad you’re getting it back.

I don't see the service department ever saying to put a car in P while driving or moving. In the end Volvo needs a new pad formula.

We can always accomplish the same thing just hitting the brakes. I did that with my S4 after washing. Guess I will do same with the XC40.

I withdraw my comment about using P button.

Someone else on here suggested it. I have used it since May with no problems but I cannot find any official notice or technical information on it to support its use so despite the fact it has worked perfectly for me I no longer endorse it’s use and will not mention it again.

Do not use the P button in motion to clean your breaks there is no written evidence that this is safe or useful.

Wish I remembered who suggested it in the first place.

OK, car is back with shiny new rotors and the Powerstop ceramic pads. Evidently the regional rep came by yesterday to check out the damaged pads and to take pictures of the new pads and such for Volvo. Now to drive these a few weeks to bed them and then start wetting them up to see if they fail.

Sure hope it solves the problem! I wonder if the cars we get in AU have the same pads? Ours are made alongside the Polestar 2 in the Luqiao plant.

 

[He Keith]

I suspect the parts are the same and made to same spec, but may be sourced differently.
