I am really chuffed with the replies as learning a lot. I used a table as an example, but with Hutch's replies I will be honest and highlight the true nature of my problem. I apologise if you felt I misled you initially, but I needed to gain some input first.
In mid August last year I purchased our current Jeep second hand and it is brilliant to drive etc. It had done less than 7k before an issue was spotted. In early Aug this year I bought a snow foam kit to wash down the car myself. On doing so I noticed bubbles on the leading edge of the the bonnet. The picture shows one bubble, but on closer examination there are a number of other very small bubbles.
The Jeep franchised dealer from whom we bought has tried their best to fob me off insisting that I should be doing all the running around and finding approved Jeep bodyshops. Basically denying all responsibility! Some that thinking was quickly rectified by myself and eventually they gave me a list of approved body shops, but I was still had to chase around. I have kept a copy of all correspondence relating to the issue.
The hood is supposed to be an Aluminum alloy and is bonded to a steel frame. Apparently there is a bi-metal reaction that maybe causing the bubbles. A body shop expert has examined the bonnet and because there was an earlier repair, the metal is now too thin to repair and a new bonnet is required at a cost of over £3000!
The approved body shop who examined the vehicle on two different occasions used different people and they all agreed that it was probably a manufacturing defect and an incorrect primer may have been used. They went onto state that they have had other Jeeps through with a similar issue.
The approved body shop has stated that due to the repair and current amount of corrosion, the fault would have been there at at time of purchase and they have supplied this in writing. I am beginning to suspect that the supplier may have had the repair done off the books to sell the vehicle which is why they were dragging their heels or maybe the previous owner had the repair done prior to trading in the vehicle.
Due to lack of action from supplier and finance house, the matter has now been escalated to FOS who have agreed we have a case. In the meantime we also contacted Jeep UK direct as the Jeep is supposed to have a 7 year panel warranty for corrosion but weirdly only if the are shows signs of pitting!
I also found out that the dealer had not submitted any claims to Jeep UK although the dealer indicated they had progressed the claim to Jeep UK. They are not answering emails to confirm or deny.
Jeep UK will be contacting the body shop to verify whether it is a manufacturing fault or not, but i strongly suspect it is due to the number of posts littering various Jeep forums.
We do not want to be paying out over £3k for a vehicle that was not even a year old from purchase date when the issue came to light. If the go ahead is given and bonnet is replaced, maybe earthing the steel frame would help. Not sure if a zinc plate somewhere would help?
