Is that a strike against HCA, or the dealership, or the service manager?
Car dealerships are both dependent on the manufacturer, and independent of the manufacturer’s control.
I put 100% of this on the service manager and to a lesser extent the dealership that permits (or worse yet encourages) them to operate that way. HCA is a long way away from this problem.
Correct. They are afraid of getting downgraded by American Honda Co, Inc. who sent the survey. I assume they are the Honda marketing and distribution arm of Honda in the USA.
I left them a bad Yelp! review and they are really pissed now.
Hey, hearing aid manufacturers and retirement planning advisers would love to talk with you over a lovely rubber chicken meal.
As for car dealerships - one time I was waiting around in the showroom for help on something and started leafing through their customer satisfaction surveys which they had in a big looseleaf notebook on a shelf. I read a few doozies of negative reviews, wandered off and came back a few minutes later to find that someone had flipped from the negative pages back to pages showing stellar reviews. 
I’ve bought things on eBay fewer than five times. I have never responded to an opportunity to rate the experience.
