Tesla hood won't open. Troubleshooting Tesla Model 3 frunk hood problems. 

Tesla frunk hood should pop up when you press open on the touchscreen or your device.

Tesla hood stuck won't open when pressing open

Some Tesla owners are having problems with a hood that gets stuck and won't open. 

In this guide, we will explain possible problems that can prevent you from opening your Tesla hood. 

Symptoms

Common problems with the Tesla hood: 

  • Tesla frunk hood stuck closed
  • Tesla hood shows open even when closed
  • Tesla hood won't open at all
  • Tesla hood pops up an inch, but the latch is still engaged. 
  • Frunk won't open at all, makes noise when pressing open. 
  • Frunk does not fully close but engages 

Possible Causes 

A common problem with Tesla vehicles especially Model 3 is that the hood may get stuck and not open due to faulty hood latch actuators. Other problems that lead to a stuck frunk hood on a Tesla include rusted cables or misaligned hood latch. 

Faulty Latch Actuators

If your Tesla hood is not opening when you press the OPEN button, the problem could be due to a faulty hood release actuator. 

Two actuators are installed next to the hood latch. The primary actuator allows the hood to unlock and pop up about an inch.

The secondary actuator serves a safety function and prevents the hood from opening up if you forget and drive with the hood open. The secondary actuator can fail, leading to the hood not opening up when trying to open the frunk. 

These actuators are electronically controlled and release the hood when the button is pressed. 

The actuators may fail and need to be replaced. Replacing a Tesla hood actuator is very easy and takes about 30 minutes. The actuator is held in place with two 10mm bolts.

Once you remove the plastic cover in the frunk, you will see the two actuators and can replace them using a 10mm wrench.

If the primary actuator allows the hood to pop up an inch, but the secondary actuator is not releasing, it is possible to release the hood manually. 

This video shows how to open a Tesla hood that is stuck due to the failure of the secondary actuator. 

Rusted Cables

The actuator cables may get stuck due to rust. 

A common symptom that your Tesla may have a frunk cable problem is that the hood can be fully closed, but it is stuck and won't pop up when you press the OPEN button. Typically if you hear a noise at the front of the hood by the front latch, it means the hood actuators are working, but the cables or latch is stuck. 

Spray lithium grease on the actuator cable and operate the cable by hand a few times to free the cables and ensure normal operation. 

Damaged Microswitches

In the hood latch, there is a microswitch that detects if the hood is open or closed. 

If the microswitch is damaged or misaligned, it may show as hood open even when the hood is closed. 

If that is the case, you will have to manually open the hood of your Tesla and either replace or realign the microswitches. 

Frunk Latch Problem

The last problem that can lead to a Tesla hood not closing or opening properly is due to a misaligned hood latch.

If your vehicle was involved in a front end collision, the front bumper might have caused the hood latch to bend. This can lead to the microswitch and actuators not work correctly, leaning to the hood, not releasing complety when you try to open the frunk. 

It is not uncommon for the Tesla front trunk to not disengage completely due to a problem with the hood latch.
