New and old Tesla Model 3 owners have been turning to the good old internet to find out why their EVs develop a nasty smell from the AC system. After just six months of taking delivery, one person asked for help on Reddit, complaining about an unpleasant odor when the AC fan starts, which is not very confident-inspiring.
As it turns out, it’s a common problem on the Model 3, and the most common fix presented in YouTube videos and on forums is simply to replace the two cabin air filters and spray a solution on the condenser when it starts to stink inside. But that doesn’t actually address the root cause, just the effect.
