Nexon EV Max knocking sound: Noticed it right after I bought the car

It was not audible when I was driving at a constant speed so I took the electric vehicle to an authorised Tata Motors service centre.

BHPian psygoon recently shared this with other enthusiasts.

I bought a NEXON EV MAX after finding the contact on OLX. The first owner was a techie, he had used it for about 5k km. The vehicle looked brand new with some of the covers still intact. I had Cars24 come and inspect the car, and after a lot of thought, I decided to take the plunge and bought it for 17 lakhs.

Now, immediately after the purchase, I observed that there was a knocking sound which came only when I pressed the throttle or decelerated (basically when the inertia of the car changed). It was not audible when cruising at a constant speed, so I took the car to the nearest Tata service centre (Prerana Motors, Peenya) and after one inspection, they diagnosed the problem as a driveshaft issue.

Apparently, the driveshaft is of a different type in some of the vehicles, and the washer in the driveshaft is faulty causing the "tak,tak" noise when accelerating or decelerating.

After a couple of days of waiting for the parts to arrive, the driveshaft was replaced under warranty. The SA said that these kinds of issues were commonly being faced by some Nexon EV and some Nexon EV Max customers.

Here's what BHPian pradheepsr had to say about the matter:

Hi

I have a similar issue with my EV Max. Had it worked upon by the team here at TAMO Service (Tirunelveli, TN). The noise was absent for some time but now it's back again after a couple of months.

My SA said he's checked everything and made the necessary replacement under warranty under instructions from TAMO, Pune. Every time they don't seem to have a clue.

I'm scared to go back there again as they would keep my car for days together for an inspection.

If you could please help folks like me with the job card details or share an invoice of the work done as well as the part replaced, it would be of immense help.

Thanks, in advance.
