Intermittent squeak sound from front after car wash

I have a **2025 Tesla Model Y**, and today after getting the car washed I started noticing a strange sound coming from the **front of the car**. It’s a **short, high-pitched squeak type sound** that happens **intermittently**. It’s not constant, it just appears occasionally generally after I parked the car. I recorded the sound here: [https://recorder.google.com/752e4575-c5c3-4592-989d-35ef2a923705](https://recorder.google.com/752e4575-c5c3-4592-989d-35ef2a923705) * The car was **washed yesterday**, and the sound started **after the wash** * It seems to come from the **front area of the car** * The sound is **very brief and high-pitched** * I’m not sure yet if it’s related to **HVAC/fan, brakes, or suspension** Has anyone experienced something like this after a wash? Did it disappear after driving for a while, or did it require service? Any insight would be appreciated.

When is it present? Just after parking? Not brakes or suspension then. You can turn HVAC off and if it continues to make the noise you rule out HVAC fan, compressor etc. Suspension would be only when you're driving so if it happens when parked would rule that out. Obviously, brakes would be the same thing if it occurs at rest or when parked it would not be brakes. Check your front radiator for small debris, may be in the fan. Also, check your frunk seals (open, close) and make sure you don't have a mouse in the frunk. Ha, but serious.

It only happens after I park the car. I haven’t noticed it while driving. The sound comes in intervals at first, and then it gradually decreases and eventually goes away. I also checked the frunk and the seals, but I didn’t notice anything unusual there. I’ve only heard the sound after the car is parked and locked so far.

# 1. Active Grille Shutters (Front Air Intake) This is the most probable cause. The Model Y has "shutters" in the lower front bumper that open and close to regulate airflow to the battery cooling system. * **Why it happens after a wash:** Water or soap can get into the pivot points of these plastic shutters. When you park, the car performs a shutdown sequence where it cycles these shutters. If they are wet or have a bit of grit in them, they will emit a high-pitched "creak" or "squeak" as they move in intervals. * **The Pattern:** You’ll hear it a few times as the car "sleeps," and then it stops once the shutters are in their final parked position. # 2. HVAC "Dry-Out" Cycle Tesla has a software feature designed to prevent mold in the A/C system. After you park (especially if the car detects high humidity, like after a car wash), it will run the internal fans and cycle the heat pump to dry out the evaporator. * **Why it squeaks:** If a tiny bit of moisture or a drop of water hit the fan bearing or a temperature sensor fan (there is a tiny one located near your rearview mirror and another in the dash), it can produce a high-pitched chirp or whine that pulses in intervals until the component dries out. # 3. Cooling Pump "Burping" The Model Y uses a complex thermal management system with pumps that move coolant between the battery, motors, and radiator. * **The Pattern:** After a wash (which can thermally shock the radiator with cold water), the pumps may run at high RPMs to balance the temperatures. If there is any vibration against a wet rubber mount, it can sound like a high-pitched squeal that gradually tapers off as the pump speed decreases and the car enters "Deep Sleep." #

Then it probably will disappear after a while. I shouldn't be worried I guess.
