In April 2015 I purchased a Nissan Qashqai with 12,000 miles on the clock, from an authorised Nissan dealer. When I booked the car in for its first service 12 months later, having done 10,000 miles, I was advised that the rear brake discs were badly corroded that needed replacing at a cost of £285.

When I challenged this I was advised that this was a common condition caused by road conditions such as salt and spray. When I insisted that this must really be a quality issue and not a result of normal wear and tear the garage reduced the cost by £50 but still maintained that this was a normal occurrence.

I immediately took my car to an independent specialist who denied this was true. They also said the brakes had not been cleaned out and greased as one might expect at a service. Am I right to feel that the dealer is trying it on?
