Yes, the underlying hardware problem was real—but “Tesla’s chips are short-circuiting” overstates what the official record proves. Tesla identified a failure mode in certain HW4 (also called AI4 or AP4) car computers. A vehicle’s power-up sequence could cause a shorting failure on the computer circuit board, potentially removing the rearview-camera image and disabling dependent driver-assistance functions. Tesla reported the defect to the National Highway Traffic Safety Administration (NHTSA) as recall 25V-002.
Tesla’s remedy, announced in December 2024, was an over-the-air software update to prevent the condition and a free computer replacement for vehicles whose computers had already failed or been damaged. In its December 30, 2024 filing, Tesla listed 887 warranty claims and 68 field reports, with no known crashes, injuries or fatalities associated with the condition at that time.

What failed?
The affected part was not conclusively identified as an individual processor “chip.” Tesla’s service bulletin describes a shorting failure on the car computer circuit board in certain HW4 units. The condition was associated with the computer’s power-up sequence and could involve a primary or secondary power component.

Early reports used phrases such as “short-circuiting chips” and discussed possible low-voltage-battery events during camera calibration. Those theories were not the same as Tesla’s later formal description. The official documents establish the circuit-board failure and its remedy, but do not prove every reported theory about the physical cause.

Contemporary owner and media reports described wider effects—including unavailable cameras, Autopilot or Full Self-Driving (FSD), GPS and navigation. Those accounts are useful context, but the regulatory recall was framed around the rearview-camera display and should not be expanded into a fleet-wide failure rate without additional evidence.
Why the rearview camera made this a safety recall
NHTSA’s Federal Motor Vehicle Safety Standard 111 requires a rearview image to be displayed when a vehicle is backing up. Tesla says the computer failure could leave the display blank, reducing rearward visibility and increasing the risk of a collision.
A driver might still reverse using mirrors and shoulder checks, but that is a contingency—not a restoration of the required camera function. The recall does not establish that every affected car became undrivable, nor does it describe an autonomous-driving behavior that caused crashes. It identifies a missing safety-regulated display and, in some vehicles, the loss of systems that rely on the car computer.

Which Teslas were included?
Tesla’s recall notice covers certain:
- 2024–2025 Model 3
- 2023–2025 Model Y
- 2024–2025 Model S
- 2023–2025 Model X
Eligibility is VIN-specific, not determined by model year alone. The affected vehicles have particular HW4 computers and were running software earlier than 2024.44.25.3 or 2024.45.25.6, depending on the vehicle’s software branch. Tesla’s recall page and the NHTSA VIN lookup are the authoritative ways to check an individual car.
Tesla’s service bulletin SB-25-00-001 R2 lists different replacement computer part numbers for Model S/X, left- and right-hand-drive Model 3, and left-hand-drive Model Y applications. That is another reason online reports about a particular model should not be treated as a substitute for a VIN check.
What owners might notice
- A blank or unavailable rearview-camera image when Reverse is selected.
- Computer, camera or driver-assistance warning messages.
- Autopilot or FSD becoming unavailable after a computer fault.
- Possible loss of navigation, GPS or other functions that depend on the central car computer, as reported by some owners and media outlets.
These symptoms can overlap with damaged camera modules, wiring faults or calibration problems. A camera that works during a short test drive can still fail after the vehicle is powered down and restarted, so intermittent behavior should be documented rather than dismissed.
Tesla’s two-part remedy
1. Preventive software update
Tesla began deploying an over-the-air update around December 18, 2024. Versions 2024.44.25.3, 2024.45.25.6 or later modify the power-up sequence to prevent the shorting condition. If an eligible vehicle has the updated software, the rear camera works normally and Tesla’s diagnostics show no damage, Tesla says no further action is normally required.

An OTA update is not necessarily a repair for a computer that has already failed or experienced the stress described in Tesla’s bulletin. Tesla’s procedure is to bring the vehicle to the applicable software version, inspect it for symptoms and replace the car computer at no charge when the failure or qualifying damage is found.
This distinction is important: software prevents this specific startup condition; it does not reverse hardware damage that has already happened.
How many cases were there?
Tesla’s NHTSA Part 573 filing is a snapshot, not a lifetime count. As of December 30, 2024, Tesla reported:
| Measure | Reported count |
|---|---|
| Warranty claims | 887 |
| Field reports | 68 |
| Known crashes, injuries or fatalities linked to the condition | None reported |
The filing does not establish that every report represented the same failure, and it does not provide a verified total number of disabled vehicles. Claims that “thousands” of Teslas were affected should therefore be treated cautiously unless supported by a separate, documented count.

It is fair to call the incident a serious reliability problem in an important computing subsystem. A failed HW4 computer can remove camera-based driver assistance and other vehicle functions, and the missing rearview display created a clear compliance issue.
But “self-driving crisis” is an interpretation, not an official NHTSA finding. The recall was not a declaration that Tesla’s autonomous-driving software had broadly failed or that every FSD-equipped vehicle was unsafe. “Self-driving computer” is a hardware label; Tesla’s consumer Autopilot and FSD features remain supervised driver assistance, requiring an attentive driver. The incident should not be confused with a claim that the car was legally or technically a fully autonomous vehicle.
Nor should it be merged with Tesla’s separate recalls and investigations involving driver monitoring, Autopilot misuse or unrelated camera-display defects. Earlier recalls covered other HW4 software issues, HW3 vehicles and Cybertruck camera behavior; those events provide context but are not the same defect.
What current owners should do
- Check the software version: Open the vehicle’s software screen and confirm whether it is on 2024.44.25.3, 2024.45.25.6 or a later release.
- Check the VIN: Use Tesla’s recall information and NHTSA’s VIN lookup. Do not rely only on model, year or forum posts.
- Test the camera repeatedly: Confirm the rearview image appears every time Reverse is selected, including after a full power cycle.
- Contact Tesla service promptly if it fails: Save warning messages, photographs and dates. Ask Tesla to check the HW4 computer under recall 25V-002.
- Do not assume the update replaced damaged hardware: Tesla’s bulletin distinguishes prevention from replacement.
- Escalate unresolved safety concerns: If a defect remains unresolved, owners can submit a complaint through NHTSA’s recalls and investigations resources.
Advice for used-Tesla buyers
- Run the VIN through both Tesla and NHTSA recall tools before purchase.
- Test the rearview camera several times, including after restarting the car.
- Ask for documentation of any prior car-computer replacement.
- Verify the installed software version and whether an open recall remains.
- Keep HW4 hardware, current FSD availability and actual autonomous capability as separate questions. HW4 does not guarantee that a vehicle has every software feature or can drive itself.
What remains unknown
The public record does not answer every engineering and ownership question. It does not provide a complete lifetime count of failures, prove that every reported loss of GPS or Autopilot came from this defect, or show whether service delays or parts shortages materially affected owners. It also does not establish whether later HW4 hardware revisions changed the board design or whether Tesla’s software change alone addressed the relevant risk.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The defensible conclusion is narrower than the original headline: Tesla had a documented HW4 car-computer failure that could remove a legally required rearview-camera display. The company issued a recall, deployed preventive software and offered no-cost computer replacement where damage had already occurred. That is significant for reliability and safety compliance, but it is not proof that Tesla’s entire self-driving strategy collapsed.
