Question HVAC issues on Model Y

Hey there,

I am in the process of buying a second handed 2025 Model Y unit. I was able to inspect the car’s in the service mode where I found many VCRIGHT_a139_hvacLHVaneFault and VCRIGHT_a140_hvacRHVaneFault repetitive alerts. When testing the frontal AC I could hear weird noises and there was not enough airflow, which matches the alert.

The car is still in warranty but I wonder: how bad this is? The car has 30.000kms (19.000 miles). I wonder if these issues are common or if they could be a “repetitive” fault. Would it be a deal breaker for you?

Repetitive just means whatever is wrong is continuously wrong.

For example: windscreen washer fluid low and you don’t top it up: you’ll have hundreds of alerts in history.
