A disappointment by maruti

I,m very disappointed with this car due to 4 main reasons, first thing,s first the door closing problem still exist, it was started observing for the Vitara Brezza that i have, still maruti have not retified the problem. The fuel economy is very low, they claim 20-28.09Kmph, but i had never achived that tag the best i git was around 16Kmph that to on economy drive, in this era of rising oil price i would prefer to spend money either on fuel efficient cars such as Datsun Redigo, TATA Tigor and Honda WR-V. or i will wait with my old wheels till the arrival of electric cars like TESLA. thirdly its body is made light weight high tensile steel which made the compromised in structural rigidity, it already failed the crash test conducted by Global New Car Assessment Programme (NCAP), I also want to remind you one thing that they made the new swift efficient by shaving out 90kg from there former 2014 model, so efficiency by sacrificing safety??? also there key-less entry knob is often a complaint, lot of my friend also shared there views regrading the same problem faced by them.
