Tesla patent addresses panel gaps using clever clamping assembly
The build quality of Tesla’s vehicles would likely see a notable improvement in the near future. As revealed in a recently published patent, the company is working on a new type of clamping assembly that allows some flexibility between panels during manufacturing. With such a system in place, gaps between a vehicle’s panels could be adjusted and aligned during the assembly process.
Tesla’s newly published patent, titled “Clamping Assembly for Securing Together a Pair of Adjacently Located Panels,” describes a simple yet clever way to address misaligned body panels. Tesla notes that conventional clamps, which are usually utilized to attach body panels to a vehicle’s frame, are unable to connect panels and their individual tolerances effectively due to their rigid structure.
“Although (conventional clamps) can be used to secure adjacently located parts to one another, the clamp does not account for parts that have large manufacturing tolerances or parts that must not be fixed in at least one direction (that is there must be play between the parts). Attempting to use a traditional clamp to secure two parts that must have some play between them may introduce unsightly gaps and/or overlaps between the parts, reducing the aesthetic appearance upon assembly.”

Tesla’s patent outlines a new type of clamping assembly that is more flexible. Such a system enables Tesla to adjust panels during assembly, allowing the company to address any possible misaligned panels before the vehicle is sent off to delivery. Tesla explains the rationale of its new clamp as follows.
“The present invention was derived in light of the foregoing challenges, and it is an object of the present invention to provide a clamping assembly that provides flexibility in securing parts that are manufactured to larger dimensional tolerances and in which play is necessary between adjacent parts during, or after, assembly. The clamping assembly of the present invention can accommodate misalignment of the part or parts owing to variances in one or both parts during manufacture and/or necessary play between the parts by allowing flexibility in adjusting the positions of the parts relative to one another in one direction while still securing the parts to one another. That is, the clamping assembly secures together a pair of manufactured parts, in which the manufactured parts require play along at least one direction while confining the movement of the parts in a second direction.
“According to certain embodiments of the present invention, the clamping assembly includes a retainer member. The retainer member may have a U-shape groove that allows for the insertion of a tab member and a narrow retaining throat that confines a bulbous portion of the tab member in multiple directions. For example, once inserted into the groove of the retainer member, the tab member with the bulbous portion is confined from moving vertically and horizontally. Once inserted into the groove of the retainer member, movement of the tab member with the bulbous portion is possible by sliding the tab member and the bulbous portion thereof relative to a plane P 2 of the groove, i.e., by sliding the tab member and the bulbous portion into or out of the page. Thus, with use of the clamping assembly disclosed herein, some play or flexibility between two panels is possible, and the panels can be adjusted relative to one another during assembly.”

Tesla has been challenged with misaligned panels on its vehicles in the past. When Detroit’s Sandy Munro started his teardown of an early production Model 3, for one, the auto veteran lamented that the vehicle’s panel gaps were so inconsistent, they were reminiscent of a Kia from the 90s. Munro was eventually blown away by the Model 3’s battery, tech, ride quality, and performance, but his criticism of the car’s build quality were notable until he completed his analysis. Tesla later issued a response to Munro’s criticism of the early production Model 3’s build quality, stating that “the standard deviation of all gaps and offsets across the entire car has improved, on average, by nearly 40%, with particular gap improvements visible in the area of the trunk, rear lamps and rear quarter panel.”
A letter to Tesla employees sent last April revealed that Elon Musk is taking the issue of misaligned panels very seriously. In his message, Musk noted that while the build quality of the company’s vehicles continues to improve, Tesla must strive to push harder in ensuring that its electric cars have design tolerances that are a factor of ten better than any other vehicle in the auto industry.
“Most of the design tolerances of the Model 3 are already better than any other car in the world. Soon, they will all be better. This is not enough. We will keep going until the Model 3 build precision is a factor of ten better than any other car in the world. I am not kidding. Our car needs to be designed and built with such accuracy and precision that, if an owner measures dimensions, panel gaps, and flushness, and their measurements don’t match the Model 3 specs, it just means that their measuring tape is wrong,” Musk wrote.
There is no denying that misaligned panels are an issue for Tesla’s electric cars, particularly early production models produced in the past. In a way, such issues are part of Tesla’s growing pains, considering that mastering panel alignment is among the more basic aspects of vehicle manufacturing. That said, Elon Musk’s unrelenting stance on improving build quality, together with clever ways to address and avoid misaligned panels, might soon allow the company to shake off its panel gap issues altogether.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.

Tesla Full Self-Driving gets latest bit of scrutiny from NHTSA
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The National Highway Traffic Safety Administration (NHTSA) has elevated its probe into Tesla’s Full Self-Driving (Supervised) suite to an Engineering Analysis.
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The step up into an Engineering Analysis is often required before the NHTSA will tell an automaker to issue a recall. However, this is not a guarantee that a recall will be issued.

The NTHSA wants to examine Tesla FSD’s ability to assess road conditions that have reduced visibility, as well as detect degradation to alert the driver with sufficient time to respond.
The Office of Defects Investigation (ODI) will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications Tesla makes to the degradation detection system, including the timing, purpose, and capabilities of the updates.
Tesla routinely ships software updates to improve the capabilities of the FSD suite, so it will be interesting to see if various versions of FSD are tested. Interestingly, you can find many examples from real-world users of FSD handling snow-covered roads, heavy rain, and single-lane backroads.
However, there are incidents that the NHTSA has used to determine the need for this probe, at least for now. The agency said:
“Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred.”
It continues to say in its report that a review of Tesla’s responses revealed additional crashes that occurred in similar environments showed FSD “did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path.”
The next steps of the NHTSA Engineering Analysis require the agency to gather further information on Tesla’s attempts to upgrade the degradation detection system. It will also analyze six recent potentially related incidents.
The investigation is listed as EA26002.
