2025 Porsche Macan — rear tires are disappearing faster than expected — Nashville owner question

ShiftHunter834Community StarterMay 15, 20262025 Porsche Macan Electric 4SNashville
2025 Porsche Macan Electric 4S, about 19,000 miles. The car is aligned and pressures are correct, but rear tire life is much shorter than my previous gas cars. Has rotation strategy, tire choice or driving style made the biggest difference? I am trying to get the facts straight before spending money.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2025 Porsche Macan so service can see what you saw. Then you'll know the next fork. Happy to compare notes if your setup is different. Not driving it hard until I know more.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2025 Porsche Macan charge sessions. I'd do that before spending real money. Have you gotten a second quote in writing? Checking again after work.

I'd treat 12V warnings as a no-ignore. On the 2025 Porsche Macan, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. That's where I'd start. On “rear tires are disappearing faster than expected,” that was the fork that mattered for me. When does it actually happen? If your situation is the opposite, ignore me. I'm in no rush to be a hero on it.

Checked the easy stuff on the 2025 Porsche Macan and found one clue worth chasing before I book a shop. Only after sitting overnight so far.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2025 Porsche Macan — site sharing and pack temp change the curve a lot. Then you'll know the next fork. If they can't show the line item, I assume it's hiding. Trying not to diagnose from the couch.

I'd do that before spending real money. If it doesn't change the out-the-door or the repair estimate, it's noise. Video is ugly but it shows the hesitation.

This is from a 2025 Porsche Macan in Nashville with 19,000 miles. Write the result down so the next test isn't a repeat of the last one. Not driving it hard until I know more.

Time, temperature, and whether it's in gear are the notes that actually help a shop. If it repeats twice more I'll book time.

It did rear tires are disappearing faster than expected twice this week, both times after sitting. No change in mileage feel. Happens in gear, not in park, for what that's worth.

I hear you, though I'd still want a second check. Leave the alerts on the 2025 Porsche Macan so service can see what you saw. That's where I'd start. Do that first. If the story changes I'll post the new data.
