Around 15 days back my Tata Safari 4x4 VX 2.2 's brake line broke and it was taken to Dinco Motors , Rewari , Haryana which is TASS.(Tata Authorised Service centre). They changed the brake line and some compressor related to brake system. They were not able to calibrate brake system with ABS and EBD, but some how they did it after 5 days.
Today I went to Dinco Motors for some work.I told WORKS MANAGER Mr.Vadhva that my safari's brake system is not working perfectly.
He said that he had test driven my safari for 20 kms and tested brakes at every speeds upto 130kmph at it was ok.
He told me that he drove my
SAFARI IN 4H (4x4) MODE AT 120KMPH.
he also adviced to switch into 4H mode at speeds above 80kmph for better stability of the vehicle.
He said that 4H MODE IS FOR HIGH SPEED HIGHWAY DRIVING.
He told me while test driving my safari HE SWITCHED TO 4H AT 100KMPH.
And 4L is for off road.
then i told him that you are 100 % wrong and why did you drove my vehicle in 4x4 on highway without having a little bit of knowledge about 4x4.
I showed him the manual which clearly states not to switch into 4H above 65kmph , and he replied it is written wrong in the manual.
The I asked a mechanic there and he also told me the same thing,
4H is for HIGH SPEED HIGHWAY DRIVING and
he was told this DURING HIS TRAINING IN PUNE BY TATA MOTORS.
I explained him everything about part time 4x4 , that 4H and 4L are only for off road not for paved roads, I explained him that 4x4 on paved roads can result in heavy damage to shafts, axles , transfer case etc.
He said that he can show me the notes that was given to him by tata motors during his training.
Now guys help me out , as I am very angry on TASS because this act may have done a lot of internal damage to drivetrain.
What should I do?
TO WHO SHOULD I COMPLAIN ABOUT ALL THIS?
And keep away from TASS as mechanic told me that all the mechanics are taught the same theory about 4x4.
