Maruti suzuki swift is a one of the most selling car of maruri. But some customers are facing some problems.
Pickup Problem
Door rattling problem
Poor rear view
Surprisingly some have poor mileage
Interior quality is so poor
Metal thickness is poor
Door and glass of door vibrates
Sudden breaking metalic and noise
Tyre bubbling noise on uneven roads
Poor Front glass
Minor improvements in last 5 6 years
CNG model is more expensive.
So its my opinion these are some problems which should be overcome by Maruti Suzuki in future.
