Why Does It Smell Like Something Is Burning In My Tesla Model 3?

The burning smell emanating from your Tesla Model 3 may come from different sources. Some of the possible origins of this odor are:

Dirty Heater

Some Tesla Model 3s, particularly the early releases, have built-in heating units. Take note that this built-in heat pump can become dirty over time. This dirt buildup can burn because of the heat, causing the burning smell. Cleaning the car’s HVAC ducts may eliminate this concern.

Incorrect Charging Cord

Using aftermarket charging cords that aren’t compatible with Tesla’s vehicles may cause short-circuits within the car’s systems. These incidents may lead to damaged wires, which may also be the cause of the burning smell.

Keep in mind that failure to repair or replace damaged electronics in vehicles, including the Tesla Model 3, may bring about further problems. So avoid using third-party parts and accessories with Tesla vehicles before consulting with the car manufacturer.

Faulty Charging Port

If you encounter a charge port error on your Tesla Model 3, it might also come with a burnt smell. Check if this assembly is at fault by opening the cover manually.

You may need to replace the entire charging module if the stench comes from this area and the green LED isn’t illuminating while you’re trying to charge.

Burnt Accessory Belt

Also called the serpentine belt, this part helps move different parts of the engine like the alternator and the AC’s compressor. But it can also become worn because of age or everyday wear and tear.

Once it begins wearing out, it may accumulate unnecessary friction that can lead to the burning smell.

Aside from these issues, your Tesla Model 3’s tires might be wearing out faster than intended because you parked it on a hot surface for extended periods. If so, you may want to read our post on how long do tires last on a Tesla to understand their durability and longevity.

The Tesla Model 3 is a fairly reliable car. However, it still has its fair share of drawbacks. Aside from the burning smell that might come from the vehicle, some unknown noises may emanate from it. These sounds may also appear even while driving on highways.

Its performance may also vary based on different circumstances. For instance, some users report that their Tesla Model 3s may become slower than usual in cold weather.

Also, the automatic windshield wipers might not function as intended, which makes manual operation for the assembly the better option.

On the other hand, the indoor climate control system can be quite consistent. The built-in HVAC system often functions as intended to set the cabin’s temperature to the correct level based on outside readings.

Does Tesla Model 3 Have A Lot Of Problems?

Apart from the Tesla Model 3 occasionally produce a burning smell, it might also be susceptible to other issues. These potential concerns are:

Entry Disabled

The Tesla Model 3 has no physical key. That means that the vehicle may deny entry to anyone, including the driver if the automatic doors malfunction.

One of the possible reasons for this error is an overheating CPU. This mishap led the carmaker to recall about 130,000 vehicles.

Premature Paint Degradation

Generally, the car's paint should last about 10 to 15 years before some degradation occurs. Some Tesla Model 3s have paint jobs that may degrade earlier than that period.

One user filed a lawsuit against Tesla after he noticed paint chipping from his Model 3 only after about 6 months of use.

Door Gaps

Gaps in automobile doors can become the precursor to different issues, such as air and noise escaping the cabin. Some Tesla Model 3 units have this problem as certain users complained that they found the gaps even after the vehicles came from the manufacturer.

Despite the existence of these gaps, these slits often pose little to no threat to decreasing a Model 3's overall driving performance. However, it might lead to the door failing to close or fall off if left unchecked. 

Final Words

The Tesla Model 3 may produce a burning smell because of different reasons. This stench may come from a dirty or faulty HVAC filter or a worn serpentine belt.

Make sure to troubleshoot the vehicle first to find the source of the scent. Once found, you can either use DIY methods or send the Model 3 to a trustworthy technician to help you solve this problem.
