2011 Hyundai Sonata Limited – harsh ride

Dear Doctor: I recently purchased a 2011 Hyundai Sonata Limited. The car is exceptional, except for the harsh ride. I’ve always used a fuel additive in my previous vehicles, but the dealer and the owner’s manual say not to put any additives to the gas. What are your thoughts? CK

Dear CK: The Sonata you purchased does have a tight suspension and that’s the way it is designed. The tire size and profile are all engineered into the design of the car. There is nothing you can do about the ride. Fuel additives are not needed in this vehicle.
