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.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
