An unexpectedly opened frunk in a car wash not only ruins the paintwork, but often also damages the hood and windshield. Several Tesla drivers recently reported that their hoods popped open during the drying process despite the car wash mode being activated – mostly in vehicles from the 2022/23 model year..
This article explains why this is the case and how you can practically eliminate the risk.
Tesla frunk pops up in car wash
| Possible cause | Explanation | Instant check |
|---|---|---|
| Operate objects emergency release | Loose charging cables, bags, etc. can press on the mechanical emergency release and trigger the lock. | Empty the frunk before each wash or use an organizer. |
| Mobile app/key fob triggers frunk | An accidental tap on the frunk icon will also open the hood in wash mode – the app takes priority. | Remove shortcut in the app or lock screen |
| Damp wiring harness/Microswitch defect | Some MY-BJ 2022 models have already had a corroded front-end wiring harness replaced – faulty contacts cause the frunk to unlock automatically. | Pay attention to error messages and have the logs read out at the service center. |
| Hood not double-locked | If the hood is only "connected" instead of being locked into place, the air pressure from the blowers can force it open. | After closing, firmly press the hood down with both hands at the level of the lock until a second click is audible. |
Step-by-step solution
-
Clean and secure the frunk
Stow away cables, bags & Co. in a Frunk organizerOur custom-fit Teslabs box prevents anything from touching the emergency release – and also keeps things tidy. -
Close the hood correctly
• Clean the lock and catch hook & grease.
• Let the hood fall shut in a controlled manner, then press down gently until the second clicking sound comes.
• Check the display to see that “hood closed”. -
Minimize mobile phone risk
• Remove the "Open Frunk" shortcut from the Tesla app or replace it with a less sensitive icon.
• Lock your iPhone/Android before starting – even if it stays in your pocket. -
Properly activate car wash mode
menu > service > Car wash mode. It closes windows and charging port, reduces sounds and deactivates windshield wipers – but does not block app commands.
If it happens anyway
-
Check fitness to drive: Fold the hood down slightly and roll slowly (max. 30 km/h) to the nearest safe place.
-
Photograph damageNote the time – Tesla can trace in the logs who (driver/app) gave the command.
-
Book a service appointmentMention your suspicion of a wiring harness or lock fault. If the defect is confirmed, Tesla usually replaces the parts free of charge.
Conclusion
With a few checks and the right accessories, the hood stays where it belongs – even when the blower is working at high pressure.
