u/1776Chad

Bought the car used about 6 months ago with 15k miles on it.

It is 4 mph slower than actual speed no matter what speed I'm going. The dealership said some of these cars have that issue and there's nothing they can do to calibrate the speedometer. It's CPO until 115k miles bumper to bumper.

I've verified this against google maps, waze, and actual radar gun, speed readers, etc. I'd like to get it fixed as it's kind of annoying. Wondering if anyone else has dealt with this issue?
