Former Ford CEO hammers Tesla’s Autopilot probe: ‘It’s half the vehicles Tesla has ever built’
Former Ford CEO Mark Fields hammered Tesla’s Autopilot probe from the NHTSA earlier today on an episode of CNBC’s Squawk Box, stating that over half of the cars the automaker has ever built are involved in the investigation.
Earlier this week, it was announced the NHTSA was launching a probe into the Autopilot system Tesla has equipped on its vehicles. The investigation involves all four of Tesla’s models from year 2014 to 2021, as it aligns with the specifications that the NHTSA’s Office of Defects Investigation listed in its preliminary report. In total, some 765,000 vehicles are going to be a part of the investigation, although only 11 crashes are listed on the document, which the agency shared with Teslarati.
“The Office of Defects Investigation (ODI) has identified eleven crashes in which Tesla models of various configurations have encountered first responder scenes and subsequently struck one or more vehicles involved with those scenes,” it says.
Fmr. Ford CEO Fields: “It’s literally over half of the vehicles Tesla has ever built.”
Mark Fields, who was CEO of Ford Motor Company from 2014 to 2017, appeared on CNBC this morning to talk about the probe. “This is a significant investigation,” he said. However, Fields misidentifies which Tesla semi-autonomous driving suite is actually under investigation, as he claims it is the Full Self-Driving package. FSD is significantly different than Autopilot based on features and functionality alone, and the NHTSA never mentions the Full Self-Driving suite at any point in its document.
Fields points toward the population density of the investigation as a telltale sign that this could be bad news for Tesla, as over half of its produced vehicles could be subjected to a massive recall that could cost the automaker billions of dollars. Tesla surpassed the 1 million production mark in 2020 and is nearing the 2 million vehicle mark this year.
“If you look at the model years, this is a very large time period they’re investigating: 2014-2021. If you look at the number of potentially affected vehicles, it’s …. literally over half of the vehicles $TSLA has ever built,” auto exec Mark Fields on the NHTSA investigation. pic.twitter.com/kwcUT5Jd47

The investigation does focus on a larger than half portion of Tesla’s production population in its short history. However, it is worth noting that the company did not mass produce vehicles until 2017 with the introduction of the Model 3. Additionally, Autopilot is available on all Tesla vehicles and was included as a standard feature in March 2019. Full Self-Driving is not a part of this investigation, and is a separate $10,000 charge on top of the vehicle’s purchase price but is completely optional.
Fields said that the investigation could take between a year and a year and a half based on his knowledge of the NHTSA investigation process. If the NHTSA concludes the Autopilot functionality is not up to its standards, it can issue a recall, Fields added.
The 11 Accidents: a Breakdown
According to the NHTSA documents, the 11 incidents involving a Tesla occurred when the vehicles collided with first responders. However, several investigations have already shown that drivers operating the vehicles in some of the incidents were under the influence of drugs or alcohol (2), had suspended licenses (1), were not following instructions that Tesla outlines for Autopilot use, or was caused by driver inattention (4).
In February 2021, a Tesla driver injured five deputy constables when the vehicle collided with a police cruiser, causing a chain collision. The driver was arrested on suspicion of DWI.
In March 2021, a driver in Lansing, Michigan, with a suspended license, crashed into a police cruiser. The vehicle was operating on Autopilot, but the driver was illegally operating the vehicle.
These are just two examples of what the accidents were caused by, and drivers could be blamed for several instances that the NHTSA lists. Autopilot has been one of the safest ways to operate a motor vehicle, according to statistics from Tesla that showed there was one accident every 4.19 million miles in which drivers had Autopilot engaged. The national average was one crash every 484,000 miles.
Turn-by-turn navigation is not new technology.
For over two decades, drivers have relied on Garmin, TomTom, and later smartphone apps like Google Maps and Waze to receive precise, reliable directions. These systems have guided millions safely through unfamiliar cities, highways, and backroads with remarkable effectiveness. They handle real-time traffic, construction detours, and complex intersections with minimal fuss.
Yet Tesla, the company that promised revolutionary Full Self-Driving (FSD), continues to struggle with this foundational capability. As FSD (Supervised) v14.3.4 has started rolling out to cars this week, navigation remains its glaring Achilles’ heel, undermining the entire autonomous vision.
Tesla Summon got insanely good in FSD v14.3.2 — Navigation? Not so much
Tesla’s FSD excels in many driving behaviors—smooth acceleration, confident lane changes in ideal conditions, and responsive handling of visible obstacles. However, when it comes to following a route accurately, the system falters repeatedly.
Owners report wrong turns, missed exits, inefficient routing through local roads instead of highways, phantom speed limit errors, and even directing vehicles to building rear entrances. Interventions for navigation issues often outnumber those for core driving maneuvers. Tesla has begun surveying owners specifically about these errors, acknowledging the problem after years of complaints.
Navigation is perhaps my biggest complaint when it comes to FSD, because sometimes, we do know better. Some of us have been living in our areas for our entire lives, but even those who have not have years or even decades of experience driving on local roads. We might know a little better about routing.
But the navigation mistakes are more than just FSD potentially taking a slightly different route that may or may not save you a few minutes. Sometimes, they’re genuinely mind-boggling.
This isn’t just annoying; it cascades into broader failures. A flawed route plan confuses the AI’s decision-making, leading to hesitant behavior, unnecessary disengagements, or dangerous maneuvers like attempting impossible U-turns or ignoring clear ramps. In a system meant to operate with minimal supervision, unreliable navigation erodes trust.
More often than not, false or plain incorrect navigation is what causes me to interrupt FSD operation. Unfortunately, I believe the latest FSD version is the worst example of it, and it leads me to believe that Tesla might be making some changes; they’ve just made them in the wrong direction.
It makes you wonder: Why is a company that has done so much with the progress of FSD and autonomy struggling so much with navigation, something that is not new and has been around a long time?
Multiple Data Sources
First, Tesla’s navigation relies on a fragile patchwork of multiple data sources—Google Maps, TomTom, OpenStreetMap, Valhalla, and its own fleet-derived data—stitched together rather than a single authoritative map. When these conflict on lane geometry, road status, or turn details, the system hesitates or chooses incorrectly.
Traditional GPS providers maintain centralized, regularly validated databases with professional curation and rapid updates. Tesla’s hybrid approach, while innovative in crowdsourcing, introduces inconsistencies that a purely vision-based or end-to-end AI approach may not easily reconcile in real time.
Persistent Learning
FSD seems to struggle with persistent learning from driver interventions.
Unlike consumer apps that quickly adapt to repeated corrections or user preferences (e.g., avoiding certain routes or remembering habitual detours), Tesla’s FSD often fails to internalize fixes on the same trip or across similar scenarios. Owners note making the same manual override multiple times without the routing engine updating its behavior meaningfully.
This stems from the neural architecture prioritizing real-time perception and control over long-term route memory and personalization, making navigation feel rigid and “opinionated” compared to the adaptive logic in Waze or Google Maps.
I noticed that when I asked Grok to try and get me home a certain way (a way that FSD routinely took in the past because it was the most efficient), it had to place a waypoint between my location at the time and my house. When I went to edit the waypoint out, as Grok had placed it for a way to get FSD to get off the highway at the right exit, it was stumped again, rerouted, and took a longer way home.
The next thing I’ve noticed, and this might be controversial, is that Nav has gotten even worse.
I think that might actually be a good thing; Tesla seems to be adjusting it. They just need to adjust it the opposite way.

Reasoning, Scaling, and Intuition
Third, scaling navigation for unsupervised or robotaxi ambitions requires not just accuracy but adaptability and user-like reasoning. Current FSD often defaults to single routes that ignore driver preferences or real-world nuances like time-of-day traffic patterns. It fails to match the intuitive, context-aware planning that traditional systems have refined over the years.
Resolving navigation is critical for several reasons. Practically, it is the backbone of any autonomous journey: without trustworthy routing, the car cannot reliably reach destinations, rendering FSD useless for robotaxis or hands-free commutes. Safety depends on it—mismatched plans create hesitation in merges or intersections, increasing accident risk.
Economically, Tesla’s valuation and future hinge on FSD delivering unsupervised driving; persistent navigation flaws delay regulatory approval and erode consumer confidence. For owners who paid premiums for FSD, these issues represent unfulfilled promises. While it is unlikely Tesla will lose too many customers due to bad navigation, some will be frustrated with the constant need for human input.
Tesla has achieved miracles in electric vehicles and battery tech. Mastering turn-by-turn—technology Garmin nailed in the early 2000s—should not be this hard. By investing in tighter data integration, faster learning loops from interventions, and more intuitive routing algorithms, Tesla could close this gap.
Until then, FSD’s navigation struggles highlight a humbling truth: even the most ambitious innovator must sometimes master the basics before conquering the future.
A Tesla Cybertruck driver in the United Kingdom had their all-electric pickup seized by local police in the Greater Manchester area after the department cited “legitimate concerns.”
Last Thursday, police saw the pickup on the roads and decided to pull the driver over. Greater Manchester Police said:
“Whilst this may seem trivial to some, legitimate concerns exist around the safety of other road users or pedestrians if they were involved in a collision with the Cybertruck.”

The Cybertruck in question was, according to the BBC, registered and insured abroad and was confiscated. The driver, who is a UK resident, was reported.
The Greater Manchester Police Department then added:
“The Tesla Cybertruck is not road-legal in the UK and does not hold a certificate of conformity.”
The Cybertruck cannot be legally driven in the UK because it has no UK Type Approval for operation in the country. This is due to some safety concerns, which are related to its angular shape and design. The stainless steel exoskeleton has sharp edges and projections that violate UK/EU rules on pedestrian protection.
Tesla has considered creating what it referred to as an “international version” that would be approved for operation in Europe. However, there has been no real movement on that front by the company, as it has been focused on the Robotaxi rollout primarily.
A new report claims that Apple is in the process of developing what would be the missing link for Tesla to get CarPlay.
Apple and Tesla have been reportedly working together for some time to give Tesla owners the opportunity to utilize CarPlay within their vehicles. While many owners are more than happy with Tesla’s in-house UI, which is seamless, effective, and smooth, some still want CarPlay, which does have its advantages.
A report from 9to5Mac now states that a new CarPlay technology that was highlighted during the Worldwide Developers Conference (WWDC) would potentially be the bridge between Tesla and Apple. With the addition of a feature known as “Route Sharing,” which gives a navigation app the ability to share routing data with the vehicle, Tesla would be able to launch CarPlay in its vehicles, the report states.
CarPlay has not been a priority for Tesla because it has done extremely well with its in-house UI, but some drivers are just used to it. Additionally, it could improve Tesla’s subpar Navigation or offer improved app capabilities, especially with iMessage.
Route Sharing is an intended addition to CarPlay’s iteration in iOS 26.4, which was released in March:
The addition of CarPlay would undoubtedly be welcome, but at the same time, it seems like Tesla realizes it is not of the utmost priority. There are so many things that Tesla is working on currently within its own vehicles, especially attempting to solve self-driving.
Back in February, Bloomberg had reported that Tesla was still working on bringing CarPlay to its vehicles, but it had not due to app compatibility issues and incredibly low adoption rates of iOS 26.
This bottleneck could buy Tesla the proper amount of time to develop CarPlay for its vehicles. It would be a welcome addition, and could be brought on with either the Summer or Fall 2026 Software Updates.
