Some of these 'warranty' covers can be so sketchy!Your lucky they sorted the wheels.
I had a new Suzuki Jeep bought new years ago, and the wheels corroded white like that in one year, and Suzuki said wheels were not covered under warranty (who reads the small print), so I had to get each wheel powder coated at my expense. Never bought a Suzuki again
Only fault I have had with a rear light cluster, was our Mitsubishi Colt and it was condensating on the inside after just three months from new, so was replaced under warranty with no hassle. Found to be a thin external crack in the make up of the plastic casing.....One weird one is that I also mentioned a internal crack appearing on one of our rear lights. The crack is clearly on the inside of the plastic, but they said not a manufacture defect. As it's not really noticeable unless you go right up to it, I'm not bothered. Just strange how it's clear that we haven't knocked it and its on the inside of the light housing, yet they didn't want to replace a £60ish cover, yet happy to replace all four alloys.
Never got one of those at allInteresting comment by colinJYD about customer feedback as yesterday, through the post came a customer survey.
