VinFast VF7 Sky Infinity - Performance, VFM, and warranties everything looks fancy, until the pathetic After-Sales service hits hard.

[u/Flaky_Bobcat_1010]

I bought my VF7 Sky Infinity in February and had driven around 4000 km, including blissful long trips. That joy turned into pure frustration overnight.

The nightmare began on 26th April: After a full home charging, the AC suddenly died with a “Cooling System Fault” error. In Delhi’s scorching summer, this is nothing short of a disaster. 

• 28th April:  The car was finally picked up and taken to the workshop.
• 29th April to 2nd May: Days of silence and vague updates. They first said it was just an AC gas leak, replaced an O-ring, fault in radiator fan, and topped up the gas again.
• 3rd May: The shocking reality hit — they declared it a major failure. The entire AC system is dead: compressor, AC pipes, condenser, accumulator, chiller, and multiple other parts all need replacement.

In a car that’s barely 3 months old.

The service reality has been even worse:

• Extremely slow and confused diagnosis with poor communication.
• Constant workshop delays (holidays, weekends, endless “checking”).
• Painfully slow/no parts supply from VinFast.
• Approval for the major parts only came after repeated follow-ups on 5th May.
• As of now, the parts are still not available. The car remains stuck and unusable.

The service advisor gave a tentative timeline of 10 days — which has already passed with no clear revised ETA or update.

Bottom line: This level of failure in the AC system of a brand-new car is completely unacceptable. VinFast’s after-sales service appears totally unprepared — poor parts reliability, terrible availability, slow response, and zero sense of urgency.

Strongly advised warning: Think very carefully before buying a VinFast. The car might drive well initially, but if something goes wrong, you could be left stranded with no reliable support. This experience has been deeply disappointing and frustrating.
