I bought a brand new Suburban 2 months ago. Last weekend it stalled and was towed away(mileage is only 1800 miles). Dealership said the fuel pump needs to be replaced. Now, I'm one of those people who knows nothing about cars except driving it. Most people have told me that I should demand for a refund or replacement(that's how I feel too). Some have told me that I should not worry because it's under warranty and just get it fixed. I'm worried though because it's a brand new truck and its having problems already. I've been in contact with GM coporate office and I'm just learning how difficult it is to deal with this kind of situation. AZ lemon makes it complicated too. There should be at least 4 repair attempts or 30 days at the repair shop. But again the truck is only 2 months and barely used. Should I just get it fixed and hope everything will be fine or should fight for a refund? Thank you for all your comments and suggestions.
