Honda Cars India Ltd. — new car rusting.

Address:

603103

Dear sir/madam,

I am writing to bring to your notice about the current state of my 2yr old car.

I had purchased a brand new honda city in the month of september 2015 from sundaram honda - chennai. I have been taking my car for regular maintenance to sundaram honda and yet in just 2yrs i have noticed a 4 - 6 inches rust forming in the two front doors.
The car is always parked in the basement of our complex.

I am writing to express my strong disappointment with your company's product. We have been using honda van & car in us with no such issues at all.

Please let me know how to resolve this rust issue and why it is happening to a new car in the first place.
