Good car with serious problems

There are 2 serious problems with this car. The first problem is the headlights on highway are just not sufficient. Distance illumination is very short and night driving is very hazardous and dangerous. Compare it with its competitors. The other more serious problem of this care is while driving the wheel nuts get loosen. Very very serious matter. I am a very experienced driver as I regularly drive RR Vogue, Evoque, Fotuner , Volvo XC 90 and others. Travel a lot on Hyderabad Ooty highway regularly as I have my house in Footy and Banglore. If these 2 problems are sorted out which are of serious nature the car otherwise is at least 4 star rating. Sort it out. The car was purchased in Hyderabad from Vibrant Ford.
