The thing is lack of experienced mechanic.
Only a experienced mechanic can co relate a problem.
we cant expect all staff to work with interest.
For condition like this in ASS
, they must have a test spare for everything. Like in dhayanidhi case , they can fix a injector and check them , if its really that problem , they can charge them after ward. A bill of 45000 for nothing is _______.
Even a local garage that get a safari once a week is far better in finding and arresting the fault , than a ass
that get 10 safari a day.
Also the other thing that can be blamed is , customers urgency.
since i am into same kinda business , the customer feels every work is damn easy . Give some time for mech and other workers to plan and work for the car. And more over mech who work under this pressure , not only does a bad work but spoils his reputation.
So from now on get the exact reason for the parts replaced , ask them to give assurance that the fault will be arrested , else the money back.
A small eg of maruti guys :
A omni(not ours) , went to service station with a complaint that a sound was comming from rear when they drive in bad road . The service people there asked him to change the rear leaf spring. and he did . A leaf spring change for just 4 years old car.
Again the problem occured and was again at the serivce station. this time they changed the tank mounting , silencer mounting etc another bill was around some 2000/-
again the problem , vexed he came to our mechanic.
After hearing his story , my mech just checked the interior of car , and found the jack lift handle was placed below the rear mat , so that made the noise in every bump.
So experiences do count a lot in service.!!
