Maruti Ritz vxi
Noise from left door, vibrations while driving at 80 km

I purchased Maruti Ritz in June. Though I had paid the entire money, the vehicle was not provided immediately as promised by the dealer (Varun Motors, Begumpet) but after one month. Secondly the car after driven 500 kms developed a problem and stopped in the middle of highway and dealer took 5 days for repairs of the fuel injection system. thirdly the car developed noice from the left door which is not rectified yet after I had left the car with the dealer for additonal 5 days. Forthly the car has started vibrating when I touch 80 kms
