Hi Guys,
I never imagined I would be writing this thread :(
Had been on a Bangalore to Mangalore return trip early December 2022, driving my Nexon BS4 D AMT which has run 11+k on odo, thanks to COVID and other cars in family, it has seen limited usage.
The car started to jerk and knock, aggravating when i take the foot off the accelerator. It's more prominent post gear change in higher gears. I moved the stick to manual mode at times and got it back home to Bangalore, as gently as I could.
The engine at idle is stable, used neutral as and when required to gain composure.
The car is just out of extended warranty, and always serviced at Key Motors, Mysore Road. So took it to them and the horror story starts.
They drove the car and said it may need an injector cleaning, they will check and let know. Few days go by and am told they want to check the injection pressure and will send it to an external vendor. If a fault is detected, a overhaul or calibration may cost like 50k.
I followed up again, they said it did not resolve the issue and want to check the fuel pressure pump, they claim to have overhauled and recalibrated all of it and unfortunately it did not resolve the issue.
Many follow ups and visit to service center, now they claim the ECU is gone because of bad signal from the acceleration sensor
Their lame explanation is driving me furious, as they are clearly not able to figure out the issue. How can a car run for 11k have a ECU failure, Fuel Pump Damaged, Injector's blocked or out of calibration all at once.
Is there anyway I can salvage and rescue the car now.
What could really be the issue here? Is there a way i can get help from TATA?
Appreciate your valuable suggestions or leads on this, thank you.
