Final Words

 I own an Ertiga Zdi for last 8 months(Bought in Feb 2013). Since last 4+ months, I am facing issue related to sudden loss of power while driving. The car has visited the service center 4 times for the same problem. Issue has recurred every time I took the car back. 

Below are the issues: 

1 - Loss of power at 1.7 to 2K rpm at 70 to 90 kmph speed followed by lot of smoke at exhaust - occurs when AC is switched on 

2 - considerable vibrations at 5th gear just before power loss 

3 - Steering jammed briefly while pressed the clutch to bring it back to lower gear followed by power loss from engine. After I engaged clutch, the power came back to steering.

I am lucky to have a very supporting dealer. They are working with Maruti engineers to solve the problem and provide me with a replacement car. But the frustrating part is the outcome of the repair. 

Areas of improvement  

Maruti/ Suzuki needs to improve their engineering division to troubleshoot and fix issues promptly to improve customer satisfaction.
