I bought Ertiga ZDi in Aug. 2012 and its now been 3 years and have done about 56000 kms., in that period I never had any accident (thanks to god) or never opened any plastic of doors etc. or got any work done from company which would require opening something as I didn't face any major issue at all.
But now after 3 years of using the car and getting it serviced all the time from company as and when required the car interior has weird sounds coming from the plastic. It sounds like car plastic is falling apart itself and making sounds on even a very little bumpy roads. The car feels like its 10 years old car and doesn't feels what it used to be.
Is there any solution to this problem ? Like applying something on nuts / bolts etc. I don't think service people at Maruti tighten every nut / bolt when the car is taken for service (as they claim).
Also the mileage of car has gone down drastically, I always do tank full and in DTE it shows that it will do about 650 kms. but it never crosses 580 now. Earlier it used to do 620-640 but now it doesn't crosses 580 at all. I am not sure what is the problem.
Now my car is out of warranty also and I have decided to get the car serviced (regular service) every 7500 kms from some 3rd party service centre like Car Nation or Bosch etc. But if there's some technical work needs doing then I will goto Maruti for that.
I am trying to drive the Ertiga in 45-60 km/h so I get to see that in the console that I am getting 30 kmpl
. Lets see if that increases the mileage but in lower gears the figure drops to as low as 5-7 kmpl where as in only 5th gear I see 30 kmpl reading that also if I am driving it in 45-60 km/h speed.
Any tips to keep the car healthy and like new would be highly appreciated. I want to get rid of the sounds coming in the interior.
