Re: n222375790-06. Due to the industry-wide semiconductor shortage, the park assist feature is not functional on this car. I was informed of this at the time of sale and told that when parts were available i would be contacted for a "no additional cost retrofit". I have not been contacted and buick now tells me i have to use nhtsa. Gov to report this issue so that my vehicle is marked "open" on the investigate vehicle history screen of the gm global warranty management system.
