Tesla Model Y mishap shows urgent need for aggressively better quality control
Tesla currently stands at the top of the auto market, and for good reason. Its vehicles provide an experience unlike any other, their performance is incredible for their price, and their tech is top-notch. Yet as the company pursues its target of delivering 500,000 cars this year, something is becoming evident: Tesla needs to aggressively emphasize its quality control, especially with regards to the Model Y.
Just recently, EV enthusiast u/Indescribables shared a verified anecdote at the r/TeslaMotors subreddit, stating that their new all-electric crossover lost its glass roof while they were driving in California’s 238 highway. According to the Tesla owner, he and his dad started noticing some wind noise inside the cabin while they were driving. They initially thought that a window had been open, but before they could check, the Model Y’s entire glass roof reportedly got blown off.
After overcoming the initial shock of the incident, the pair drove back to the Tesla delivery center. Upon inspection, the manager at the Tesla location reportedly noted that the incident was caused by either a faulty seal on the glass roof, or someone from the factory forgot to seal the roof on. The new Tesla owners were then given a loaner as well as the option to repair or replace the Model Y. The pair declined a repair, instead opting to have the vehicle replaced.
So Tesla’s quality control is really bad. Our brand new model y’s entire roof just fell off from r/teslamotors
Granted, such an account is strictly anecdotal, but it does highlight a notable point of improvement for Tesla. As the company grows, after all, the electric car maker must make it a point to ensure that its quality control matches its pace of innovation. This ensures that every new Tesla owner gets to experience the same type of experience that has inspired such a strong and dedicated following for the company and its CEO, Elon Musk. This becomes challenging if some vehicles end up leaving the factory without being properly checked for potential build issues.
This is especially notable with this recent Model Y mishap, since Elon Musk himself has proven in the past that he is not content with Tesla making cars that have subpar build quality. During the middle of the Model 3’s “production hell” in 2018, reports were abounding that some vehicles being delivered to customers were not up to par in quality compared to the company’s previous cars like the Model S. Musk then sent a letter to Tesla employees calling for vast improvements in build quality. Musk’s intent was clear.
“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.
Tesla Convertible???
The improvements in the Model 3’s build quality did not happen overnight, but once the company was able to get better, even legacy auto veterans could not deny that the all-electric sedan was being built with world-class standards. Longtime GM executive Bob Lutz, who is typically critical of Tesla, pretty much threw in the towel when he encountered a Model 3 in the wild. The following excerpt from a post Lutz shared on Road and Track explains his observations best.
“When I spied a metallic-red Model 3 in an Ann Arbor parking lot, I felt compelled to check it out. I was eager to see the oft-reported sloppy assembly work, the poor-fitting doors, blotchy paint, and other manifestations of Tesla CEO Elon Musk’s ‘production hell’ with my own eyes.”
“But, when next to the car, I was stunned. Not only was the paint without any discernible flaw, but the various panels formed a body of precision that was beyond reproach. Gaps from hood to fenders, doors to frame, and all the others appeared to be perfectly even, equal side-to-side, and completely parallel. Gaps of 3.5 to 4.5mm are considered word-class. This Model 3 measured up,” Lutz wrote.
What is rather interesting is that Tesla, especially the Model 3, enjoys widespread support from its consumer base. A thorough study from Bloomberg which polled 5,000 Model 3 owners found that buyers of the all-electric sedan were extremely happy about their cars despite the occasional cosmetic issue. Almost 99% of Model 3 owners remarked that they would recommend the car to friends and family. These are remarkable results, and it speaks volumes about the disruption that Tesla is really bringing to the auto market.
But the company could do better. Adopting a more aggressive quality control system is one way to do this.
Tesla has grown at a pace that is almost unprecedented, transitioning from a maker of premium cars like the Model S and Model X to a mass-market automaker that produces the Model 3 and Model Y in but a few years. With this transition came challenges, as evidenced in the well-documented “production hell” that Tesla experienced during the initial Model 3 ramp. The company has since overcome its quality issues with the Model 3, but it appears that the same pattern is somewhat happening with the Model Y’s ramp. This has to improve.
Considering the company’s goals, from its 1-million-vehicle-per-year target and more importantly, its mission, Tesla must simply not tolerate errors such as releasing a vehicle without proper glass roof sealant to delivery centers. These errors must be beneath Tesla’s Fremont plant at this point, especially since cars from the company’s China factory, Giga Shanghai, have been heavily praised for their build quality, as per data from Chinese quality complaint company CheZhiWang.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
