Google this to see about your steering. Sounds like a variable ratio mechanical system.
Electromechanical power steering with Direct-steer
The steering system adjustment won't fix a pull to the right, that will be from an alignment issue. Have they put it on the alignment rack?
I discussed electric steering and electronic steering with the SA. Two different things. He kept referring to "electronic" steering and that was what he claimed they adjusted to no avail. He could never explain what "electronic steering" was. It sounded like he made it up to make it look like they actually did something.
Yes, they checked the alignment first time at my request as recommended by Discount Tire ("tar" in Texas). No pull BEFORE I brought it in, only after they aligned it or whatever else they did.
No call today. With Mercedes me Driving Journal now on, I see they moved it a few times a few blocks between 6:58 and 9:25 today. Wish I had had it on when they drove it 30 miles in one day without noticing, finding, or fixing the problem they created. Also set 65 mph speed alert. Handy service, I recommend it if only for service. Has to be reset every 24 hours, so don't let it lapse.
After claiming he was going to park the car in the garage, the car was hot from the Sun when pulled up for the test drive. There was a hailstorm overnight at my house six miles away, but luckily it missed the dealership.
Day Nine starts tomorrow.
