I have a 2011 Nexo and have water ingress in back external horizontal panel which has led to rusty water running down the back of the van. All warranty conditions have been met and the company (Burstner dealer in Cheltenham) who has completed the habitation service for the past two years, refuse to do the warranty work. They say I must return it to the original dealership of purchase. This is 340 miles from my home! I emailed Buerstner.com asking for advice two days ago, awaiting a response. Has any other funster had this experience, if so how did you manage it? If you have a van still under warranty and live a long way from the place of purchase, beware!! Frustrated and a tad grumpy.
