Why would a Honda Dealer lie to a customer telling him nothing is wrong with his ATV?

The same reason you lie on this site - they have a lot to hide.

I'm a honda dealer and we will always take as many service jobs as we can. I can understand warranty claims being ignored because honda pay us very little to carry out warranty claims and if you have rusty bolts / broken bolts ect we LOSE money because it takes longer then honda will pay for. But as it wasn't under warranty I would guess your friend asked them to look at the engine and not the quad itself? or they put an inexperienced employee onto the job? When it comes to things like this I promise you it's not the dealership themselves. It's the employee who can't be bothered to work on a muddy rusty quad or things along them lines. Dealerships are businesses we make more money by keeping long-term happy customers that return year after year for servicing and repair. If you sell a quad and make say $1200 that's a one time thing but if that same customer gets his quad serviced with you for the next few years your get a better profit. At our shop we've returning customers from 15-25 years ago that will not go anywhere else because of our great service and willingness to help as much as we can. No dealership will throw away business and face losing a returning customer. It's the people within the business that have no gain whether they service your bike or not. the guys who just work at a shop and just look forward to there pay check and take no pleasure or pride from doing a good job done right. I don't mean every dealer you go to will have people like that but some do. This is all just my opinion but it would of been best to tell the boss of the dealership and see if they will fix it for a discount. Also Honda are very strict about customer service, If you email Honda direct they will atleast write the dealership to resolve any issues.

Sounds, like no one actually looked at it in the first place. A mistake?

They're just there to make it look like if you buy the things they sell, you'll be taken care of while you own it. But you won't! Even when you are under the best service plan, they only pretend to do stuff like change oil, fluids, windshield wipers, broken parts, etc. It's a hoax.

It's a Honda what do you expect! you moron.

Its a honda you silly.
