On some Model Y vehicles, water may ingress into the front fascia camera via the channels on the front fascia harness. This may corrode the camera connector or submerge the camera lens, which results in camera alerts and possible loss of the front fascia camera feed. Inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the front fascia harness and the front fascia camera.

The failure pattern owners describe
A pattern of electrical and computer failures has emerged in 2025 Model Y complaints, with the AP4 computer being the critical failure point. Owners report the AP4 fails either suddenly or after software updates, wiping out all cameras, GPS, cruise control, forward collision warning, lane keeping, blind spot detection, automatic emergency braking, and parking assist. One owner waited 2.5 months across three rescheduled service appointments for a replacement part; another was told parts wouldn't arrive until January 24, 2025, with no loaner provided. A new vehicle with under 1,000 miles is unusable.
Separately, a comprehensive brake and traction control failure occurred before a collision; the vehicle's safety systems were offline when needed most. An Autopilot malfunction allowed a vehicle to run a red light; another crashed into a pole while in Autopilot mode and caught fire, killing the driver. A windshield seal failure following Tesla service caused water intrusion that shorted the electrical system and created fire risk. A hood latch failed at highway speed, shattering the windshield. One owner detected unfamiliar key fob activity and had the charger port open itself repeatedly. The horn stops working during rain—a federally mandated safety feature lost in wet conditions. Two battery fires are reported. Tesla service centers have denied loaner vehicles and stated some failures are "normal operation."
Failure modes owners describe
AP4 Computer Failure
Complete shutdown of the AP4 computer module, which controls all Autopilot cameras, driver-assist systems, and navigation.

Symptoms owners cite: Touchscreen goes completely black; Loss of access to critical driving and emergency controls; Requires full hard reboot to restore functionality
Repairs/costs cited: Hard reboot via vehicle systems required for restoration; Tesla service inspection did not identify underlying cause
Recalls/TSBs owners mention: Tesla service center inspection; issue not resolved
Brake and Traction Control System Failure
Safety-critical braking and traction systems disabled during normal operation. Traction control warning displayed followed by automatic vehicle hold/brake hold disabled warning. Failures occurred before a collision and prevented the vehicle from warning or braking to avoid impact.
When: During normal highway driving prior to collision event
Symptoms owners cite: Traction control disabled warning; Automatic vehicle hold/brake hold disabled; Automatic emergency braking failed to activate; Forward collision warning not functioning; Vehicle did not warn or slow down before collision
Recalls/TSBs owners mention: Service center declined to provide towing or loaner vehicle during 30-day investigation
Camera and Perception System Failure
All camera systems stop functioning, eliminating Autopilot perception, backup camera, and visibility aids. Backup window also becomes unusable with severely darkened/discolored rear glass. Multiple owners report all cameras non-functional simultaneously.
When: Occurred without warning in multiple cases; one owner reported on January 13, 2026
Symptoms owners cite: All cameras stop working; Backup camera non-functional; Forward collision warning unavailable due to no camera input; Autopilot cannot function; Navigation cannot function; Rear window darkened/discolored, impairing rear visibility; Loss of critical safety perception systems
Restraint System and Airbag Failure
Safety restraint systems fail, preventing airbag deployment during a collision event. Both front left and front right restraint systems report faults. Airbags did not deploy despite collision conditions that suggested deployment should occur. System remained offline after the collision.
When: During collision event; failures persisted afterward
Symptoms owners cite: Automatic emergency braking unavailable; Safety restraint system faults on front left and front right; Airbags failed to deploy during collision; Persistent airbag and seatbelt system error icons; Restraint system goes offline
Frunk (Front Hood) Unlatching and Windshield Damage
Front trunk latch system failed, causing the hood to open unexpectedly at highway speed. Hood flipped backward over windshield and shattered it, creating total loss of forward visibility and serious crash risk. Vehicle had approximately 30,000 miles and was less than one year old. A bolt was found completely out of place after the incident. No prior warnings or alerts indicated improper latching despite the vehicle failing to detect the unlatch condition.
When: At highway speed; vehicle had approximately 30,000 miles; less than one year old
Symptoms owners cite: Front hood opened unexpectedly at highway speed; Hood flipped backward over windshield; Windshield shattered; Total loss of forward visibility at highway speed; No prior warning or alert of improper latching; Bolt found out of place; Latch detection system failed to warn of unlatched hood
Recalls/TSBs owners mention: Prior recall related to hood latch detection issues noted by owner
Water Intrusion from Windshield Seal Failure
Following a windshield replacement performed by Tesla service, catastrophic water intrusion occurred during rainfall. Water dripped directly through windshield seal into cabin, soaking dashboard electronics, floorboards, and brake pedal area while vehicle was being driven with three children in rear seat. This water intrusion triggered an active electrical short circuit and autonomous hazard light activation.
When: During rainfall after windshield replacement; occurred within 3 weeks of the replacement service
Symptoms owners cite: Water dripping through windshield seal during rainfall; Water intrusion into cabin and soaking dashboard; Water entering from brake pedal area; Active electrical short circuit triggered by water intrusion; Hazard lights flashing autonomously; Electrical system severely compromised; Vehicle grounded and undrivable; Electrical fire risk
Repairs/costs cited: Vehicle requires towing; windshield seal replacement or resealing needed

Horn Failure in Wet Weather
Horn becomes muted or non-functional during rain and wet conditions, despite functioning normally in dry weather. Tesla service center stated the horn works normally when water dries out, implying this is normal operation. Owner reports this is a common problem among Model Y owners and a serious safety defect since the horn is a federally mandated safety feature, particularly critical during reduced-visibility rain conditions.
When: During rain and wet weather conditions
Symptoms owners cite: Horn becomes muted or inaudible during rain; Horn functions normally in dry/sunny conditions; Loss of critical safety feature during low-visibility rain driving
Recalls/TSBs owners mention: Tesla service technician stated horn works normally when water dries out, implying this is acceptable; no fix offered
Unauthorized Key Fob Activity and Potential Security Breach
