The problem is more often the dealers.
They’ll typically only get somewhere between 50-70% of their retail labour rate for warranty work, as the manufacturer sets the labour rate. And there’s no sneaking anything extra on to the warranty bill, like they can do with retail work. So they’ll often do their utmost to avoid warranty work.
I’ve seen local dealers try it on with my employer. Best one was the Honda dealer who tried to bill us several hundred pound for a new seat base for a ten day old CRV, after the adjuster came of in the drivers hand. My boss told them somebody would get back to them. He then phoned our HQ, and 10 minutes later Honda UK were on the phone, asking exactly what had been quoted, informed him it was a known problem, the part required to fix it was £16, and there was no doubt that it was covered by warranty.
Said CRV was delivered back next day, fixed, and with a box of chocolates for the driver. That dealer has been very helpful ever since.
