TL;DR Update: Instead of fixing my car, the dealership is interrogating me about my social media posts. Customer care has no idea about basic geography. But the craziest part? The dealership just admitted that the technical team is still asking for videos and reports today - which means their verbal "warranty denial" a few days ago was completely made up to avoid liability. I am physically and mentally exhausted.

Hi everyone. First of all, thank you to everyone who supported my last post. I am writing this update because I am completely helpless and honestly losing my mind with the level of apathy from VinFast India and CASA Cars Vijayawada.

For context: My 4-month-old VinFast EV died on the highway after 30 mins of rain. It’s been sitting dead at the service center for 12 days.

Here is the absolute circus I have been put through today (May 12th):

• 9:30 AM:  It’s Amir, the Service Manager at CASA Cars. Is he calling with a diagnostic report? No. He is calling to interrogate me about why I posted about them and VinFast online. I told him straight up: I am helpless, my emails are ignored, and I am just stating factual updates about where my car is. He promised to ask the VinFast team to call me back.
• The Twitter "Promise": The official VinFast India handle replied to my tweets promising a callback. Shocker: Nobody called.
• 11:50 AM - Call #1: Out of sheer desperation, I called the VinFast toll-free number. The executive heard my entire painful story again, read my ignored emails out loud, and tried to call Amir. He didn't pick up. She promised to call me back in 30 mins. It never happened. I tried calling and WhatsApping Amir directly. Complete radio silence.
• 1:00 PM - Call #2 : I called customer care again. A new guy picks up. I have to relive the trauma and tell the whole story from scratch. This executive didn't even know that Hyderabad and Vijayawada are two different cities! He kept trying to contact the Hyderabad service center until I had to literally teach him geography on the call.
• The Massive Lie Exposed: The new guy finally gets Amir on a conference call. Amir then drops a bomb: He says the VinFast technical team called him today to ask - yet again - if the car was driven in the rain. He said they are now asking for new videos of the car and more technical reports which he will send tomorrow.

Wait. Read that again.

If the VinFast technical team is STILL asking for basic videos and trying to diagnose the car TODAY... on what basis did they verbally deny my warranty for "customer fault" a few days ago?! It proves they literally just made up the warranty denial to scare me off and avoid taking responsibility, without having any actual technical proof.

• Blocking Escalation: Amir said the Regional Manager (Bhavani Shanker) might call me. I have zero hope. To take matters into my own hands, I asked Amir to share the email IDs of the CASA Cars dealership management. He flat out refused. He said he cannot share their email addresses without "approval." Since when does a customer need approval to email the management of the dealership that is holding their car hostage?

I am so drained. I invested my hard-earned money into this car to support my business travel, and I am being treated like a criminal for driving in the rain.

What should my next legal move be here? Can they legally withhold dealership management contact info and diagnostic reports like this?

And I am thinking of sending legal notices to Company, and Dealership - Is it a good move?

Please keep sharing. I don't want anyone else to go through this torture.

TL;DR: Bought a VinFast EV 4 months ago. Hit heavy rain on the highway for 30 mins. Car threw High-Voltage faults, went into limp mode, and completely died. Service center has no equipment to check it. VinFast corporate verbally denied the warranty claiming "customer fault" for driving in the rain, but explicitly refused to give me the written diagnostic report. They are now ghosting my emails and cutting my calls.

Hi everyone,

I am posting this as a desperate plea for advice and to warn anyone considering buying a VinFast in India. I am facing a literal nightmare with this company.

Background: I run a highway rest infrastructure startup (PowerNAP), which means I practically live on the highways. I average around 5,000 KMs a month. I bought my VinFast EV on December 25, 2025, expecting a safe and reliable highway cruiser. It didn't even last 4 months.

The Breakdown (April 30th):

• Traveling from Hyderabad to Vijayawada.
• Approaching Vijayawada, I hit heavy rain for the very first time in this car. It lasted maybe 30 minutes.
• Note: I was driving safely on the main highway. The car was NEVER submerged, and I did not drive through any waterlogged areas.
• Suddenly, the dashboard lit up like a Christmas tree: EV Battery Fault, High Voltage Battery Warning, and 12V Battery Fault.
• The car violently dropped into limp mode (~20 km/h) making it incredibly dangerous on a wet highway. I had to pull over 6-7 times. It eventually refused to charge and died completely.

(See attached images of the dashboard errors and the car on the flatbed)

The Service Center Joke (CASA Cars, Vijayawada): The car was towed on May 1st. The Service Center Manager told me they don't even have the required lift to do a proper High-Voltage battery inspection. My car just sat there gathering dust while my emails to corporate went completely unanswered.

The Scam (May 11th - Today): After 11 days of silence, the Service Center Manager called me with an update from VinFast's central tech team.

1. Warranty Denied: They told me the catastrophic high-voltage failure is a "customer fault" simply because the car was driven in heavy rain, and I have to claim my personal insurance.
2. Hiding the Evidence: I demanded they email me the diagnostic report proving this. The manager flat-out refused. He said VinFast management gave strict instructions NOT to share any internal emails or written diagnostic reports with the customer.
3. Ghosting: Over 9 detailed escalation emails to their grievance officer and management have been ignored. When I call customer care now, they put me on hold and abruptly disconnect the call.

My Question to the Community: If a modern electric vehicle cannot survive 30 minutes of standard highway rain, how is that not a severe manufacturing and sealing defect? Blaming me while hiding the technical evidence is a massive violation of consumer rights.

I am facing huge business disruptions and mental stress because of this.

1. Has anyone dealt with something similar regarding EV battery warranties in India?
2. What is the fastest legal route here? Should I send a legal notice immediately or go straight to the consumer forum?

Please upvote/share for visibility. Auto companies cannot be allowed to treat Indian consumers like this and get away with it.

VICTORY!!!
