My ertiga completed 36k without any big or small issue. just periodic services.
parts replaced till now : none, even front disk pads are not changed yet & its the same that come with car
. planning to take car for check up as i never seen so long life of disk pads in any of my cars, till now no noise or anything from brakes.
from last 2 months i have to drive ertiga for around 480km every weekend on a single day, i check fuel efficiency with different driving speeds as shown below. also this include 100% ac use with some times ac is used for 20-30 min in parked vehicle.
avg. speed with AC on & 2 persons efficiency
80+- 10 km/h : 21 km/L
90+- 10 km/h : 19 km/L
100+-10 km/h : 18 km/L
120+-10 km/h : 17 km/L
(120km/h speed is tested on highway from sonipat to till Karnal in early morning & i will not recmend this speed to any one. i have driven at this speed with full care. although car feels fully stable at this speed)
