The above two posts summarize the reason of the defect and your mental stress.
Cars get damaged during transport. They come out pretty neat out of factory and are QA reviewed. Atleast such a big error cannot be ignored before dispatch.
Its a known fact that dealerships repaint bumpers, and panels when they themselves receive damaged paint during transport. The good thing with this is that, atleast the paint is original and the baking time is properly given.
The bad thing is that they dont have time to match colours.
Now coming to the second aspect, my humble opinion would be same as second quote above. You should not have taken delivery.
In realistic terms, your car wont be replaced. Forget it.
You wont be paid any charges for the trouble caused. Forget that as well.
The only thing that is possible is that they will ask you to return the car for fixing. They will repaint it. And since it wont bring them (the dealership) any extra money, just a headache, chances are that the next repaint will be poorly done. (Been there, done that)
Next, they will clear coat atleast the adjacent panels to match the shine, which infact is a big big big issue as it will become apprent in the following 12 to 24 months.
The max you will do, with support from consumer court as well...... to ask them to repaint again and again untill you either give up or they somehow convince you that THAT IS HOW IT CAN ONLY BE DONE.
If you ask me, I would rather get a letter from the dealership that this Piece of Panel (door) is infact repainted at dealership prior to initial dispatch to buyer. This may just help you during resale of your car. or atleast give you peace of mind that the dealership formally accpeted in Black and White.
What they accpet now as a mistake (assuming that they accept their fault), will unfold once you ask this to be written in black and white. Strive for that and be at peace.
And Note to any future buyer of Brand New car:
Always receive the car in good lighting conditions. Some dealerships dispatch from workshop floor (poorly lit to spot minute paint defections), saying that the car is brought here for last minute fluid inspections and inventory check. If possible, dont sign receiving unless you inspect the car outdoors
Always check all accessories, fluid levels, toolkit, lifting jack etc.
I personally had a bad experience when a friend took me along to inspect the car at dealership. No Alpine Faceplate, No Roof Antenna, Coolant Reservoier level more than half less between MAX-MIN marks.
Yes, I agree that the car is dispatched from factory like this, most of the times, AC fuse / relay also removed, fuel almost empty,
But that doesnt mean they forget to re-install all that before calling you to collect your car.
