[Need Advice] Dealing with a defective car for 3 years – Consumer Court options in India?

Hi everyone,

I’m seeking guidance on how to escalate a persistent issue with my 2023 Hyundai Verna. I’ve been dealing with recurring mechanical defects (ABS and Auto Hold malfunctions) for three years. Despite numerous service center visits, the issues are never permanently resolved.

The Breaking Point:

Recently, the ‘Auto Hold’ feature failed on a slope, causing my car to collide with a parked vehicle. I had to pay for these repairs out of pocket.

My Current Situation:

Persistent Defects: The car has been off-road for long periods, yet the dealership keeps returning it with temporary "fixes."

Safety Risk: These malfunctions are legitimate safety hazards.

Lack of Support: The manufacturer and dealership have failed to offer a courtesy vehicle or a permanent resolution, and they have denied requests for a replacement vehicle.

I am now ready to move toward formal legal action.

My questions:

What is the process for filing a case against a car manufacturer/dealership in the Consumer Forum?

Should I issue a formal Legal Notice through a lawyer before filing a consumer complaint?

Besides service records and accident photos, is there specific documentation I should gather to prove "manufacturing defect"?

Any advice from lawyers or people who have successfully navigated Indian Consumer Courts for vehicle disputes would be deeply appreciated.

NOTE: Used AI to summarize the draft with my mail chain to Hyundai.
