Teslas do that. Mine doesn't

The Renault Zoe has a heatpump (integrated with the cooling system so it can use waste heat) and it's not exactly a high-end vehicle. On a 30 minute drive last weekend (around 8C outside temperature, cabin temperature set to 20C) it used 0.2 kWh to reach and maintain cabin temperature.

f4eru:
Cool, didn't know that the Zoe had this... My Tesla doesn't (too old, now it's a standard on all new ones).

I hope it gets to be a standard equipment soon on all cars.
VW still has it as a paying option....

Enough surface rust near the circumference of the brake rotors had formed to produce a slight grinding noise on right turns (as the inner pad dragged along the rusty border between swept and unswept).

A quick sanding to remove that rust, brake pad check (50% or so left on front, 25-30% on rear), front<->rear tire rotation, and everything is back in order. It’s impressive how little maintenance has been needed (aside from the battery pack module replaced under warranty, which is big for Nissan, but free for me).

As a cheap run around town car, it fits the bill nearly perfectly.

A slight grinding noise on turns is a sign of a worn wheel bearing. OR, in the past somebody forgot to tighten the driveshaft nut on a front wheel drive. Save for marginal brands, wheel bearings wear due to water going past the ( marginal ) seals built into them. On modern cars they are angular contacts, back to back ( inners), factory preloaded, in a common outer race. That makes testing them almost impossible when the wear is marginal as the bearing shows play only when the weight of the vehicle bears on it.

sokoloff:
In this case, it was rust on the unswept portion dragging. 45 seconds per side with a flap disk and the noise (which was entirely repeatable previously) went away entirely.
