I feel your frustration bkuz
. I've got similar dents. Mine are over both the drivers door and passenger door. They are very hard to see unless in the right light but once you see them you can't help but notice them. I took it to a paintless dent repair guy & he said he couldn't do anything because they are right at the reinforced area over the doors. I'm curious, did your dealer say what they did to fix them? I took some snap shots back when I first noticed them (almost 2 years ago) but they have worsened since and are a bit more noticeable now.
Here's what they look like today (excuse the dust, it's super windy here today):
I really baby this car but that didn't stop me from doubting myself and thinking maybe I caused the damage during a wash and wax or something. The dent guy said it was unlikely that I did the damage since that reinforced area would take quite a bit of pressure to create the dents. We even theorized that maybe the car hauler driver stood or kneeled on the car maybe to fasten a car above it for transport. Who knows? Your weather change theory makes more sense since I drove mine cross country from snowy Pennsylvania to sunny California when I purchased it.
Even though you can't see them unless you are looking for them, they still drive me crazy. Most people don't notice them but I do every time I look at her. These dents are the ONLY thing I hate about my car.
