Strange noise from my Tata Harrier when driven over bumps

This occurred in my SUV straight out of the showroom on the delivery day.

BHPian kapilnitdg recently shared this with other enthusiasts.

Dear BHPians,

I am getting a strange and irritating noise from the front of my new Tata Harrier XZA Nov 21 make, when driving over sharp bumps. This issue is coming when driving a little fast over sharp bumps. The issue does not occur on softer bumps and if we pass the car at a very low speed <5km/h.

This occurred in my car straight out of the showroom on the delivery day. Since then my new car is lying at the Service Center and they are not able to figure out the issue. I escalated the matter and the plant team visited and they are saying it’s common noise but, to be honest, it’s a very irritating thud noise. Looks like they want to wash their hands off.

I suspected some loose sway bar bushings or strut mounts, engine mounts but the SC says they have checked it and could not locate the sound. The plant team visited and they are saying it’s common noise across some Harriers and saying it’s normal Just want to understand what are my options here? Did anyone face a similar issue with a new car?

Here's what BHPian kushagra452 had to say on the matter:

I think the Tata guys are indeed correct. Going fast over bumps will certainly produce a faint thud sound. I don't think there is anything unusual. If I were you I would take back the car immediately. In all likelihood, the car is merely parked in the workshop as is, since there is nothing to be worked on in a brand new car.

Here's what BHPian Kosfactor had to say on the matter:

Take the vehicle to a reputed wheel alignment shop, ask them to test drive it and diagnose the issue. It may very well be some suspension bush or a loose steering rack.

Here's what BHPian zeng had to say on the matter:

As you suggested, it could well be sway bar bushes.

Assuming its tightening torque was proper, what about inserting 'shims' in between bush od and bush clamp?

Alternatively, it could be an absorber link issue, but unlikely IMHO.
