Tales from a Tesla Model S that hit 400,000 miles in 3 years
Tesloop, a Tesla-only intercity shuttle service for Southern California commuters, has reached another milestone with its Model S 90D. In a recent announcement, the company revealed that their Model S, dubbed eHawk, has passed the 400,000-mile mark, making it as one of the highest mileage Teslas in the world today.
eHawk entered service on July 2015, driving from city to city in Southern California and Nevada. By February 2016, the Model S 90D had logged its first 100,000 miles, and by August that year, the full-sized family sedan passed the 200,000-mile mark. In a recent blog post, Tesloop stated that roughly 90% of eHawk’s trips were driven using Autopilot, with Pilots (as the company refers to its drivers) only taking over active driving duties when needed. Tesloop’s Model S 90D currently travels an average of 17,000 miles per month. On the company’s recent post, Haydn Sonnad, Tesloop’s founder, expressed his optimism for the coming years.
“Vehicle connectivity is about to transform the car ownership and user experience. We are close to the point where increasingly sophisticated autonomous driving features and deep connectivity are coupled with electric drivetrains that last hundreds of thousands of miles, a whole new approach to mobility can be offered, that will transform the economics of car ownership and usage, while offering a greatly superior customer experience,” he said.
Over the past 3 years and through 400,000 miles on the road, eHawk has accumulated roughly $19,000 worth of maintenance costs, equating to about $0.05 per miles. This cost is broken down to $6,700 for general vehicle repairs and $12,200 for regularly scheduled maintenance. According to the company’s estimates, a Lincoln Town Car or a Mercedes-Benz GLS class would have accumulated maintenance costs of $88,500 ($0.22/mile) and $98,900 ($0.25/mile), respectively, had the vehicles been driven for 400,000 miles.
The Model S 90D’s high voltage (HV) battery unit was replaced twice under warranty since July 2015. The first battery HV battery replacement was at 194,000 miles, while the second was at 324,000 miles. Average battery degradation over the vehicle’s first 194,000 miles was around 6% with multiple Supercharger stops every day. Between 194,000 – 324,000 miles, the HV battery degradation was estimated at around 22%. According to Tesloop, this was likely due to the company’s practice of constantly charging eHawk to 95-100%, instead of Tesla’s recommended 90-95%. On its blog post, Tesloop shared Tesla’s reminder to the company after its first HV battery replacement.
“Found internal imbalance in HV battery due to consistent supercharging to 100% from a low state of charge (SOC) without any rest periods in between. HV battery has been approved to be replaced. Also recommend that customer does not Supercharge on a regular basis and does not charge to 100% on a regular basis. We also recommend that the customer use scheduled charging to start charge 3 hours after end of drive at low SOC.”

Apart from its HV battery, Tesloop’s Model S 90D also had its front drive unit replaced under warranty at 36,000 miles. No issues with the vehicle’s drive units have emerged since. The Tesla-exclusive shuttle service also opted to upgrade the rear seating of eHawk to the executive seat option for maximum passenger comfort. According to the company, the seats have held up well over the thousands of passengers the electric car has transported over the years.
Considering the endurance showcased by its Model S 90D, Tesloop estimates that eHawk should be able to last another 600,000 miles over the next five years. If the vehicle achieves this, it would be the first Tesla Model S to reach the 1 million-mile mark.
Tesloop currently operates a fleet of Model S and Model X vehicles. One of its Model X, a 90D named Rex, also achieved its own milestone last month, after it hit 300,000 miles on the road since being deployed. When the all-electric SUV reached the 300,000-mile mark, its battery degradation was estimated at roughly 10%. Since achieving its milestone, however, Tesla has changed the vehicle’s rear drive unit.
Tesla just upgraded its headlights through a software update, making them even better without any physical or hardware upgrade.
Tesla’s latest software update is quietly improving nighttime driving for a small number of owners. Version 2026.38 includes a new capability called Dynamic Headlight Leveling.
The feature automatically adjusts the aim of the low beams in response to driving conditions and nearby traffic, with the goal of giving the driver more usable light on the road while reducing glare for oncoming vehicles and traffic ahead.

Model 3 gets Dynamic Headlight Leveling — low beams auto-aim around traffic for max visibility, less glare. Model 3 / Y (AMD HW3) also pick up sharper Tesla visuals + an enhanced park scene on the center display.

Unlike Tesla’s matrix high-beam system, which selectively dims individual LED segments to create shadows around other cars, Dynamic Headlight Leveling physically tilts the low-beam projectors. Internal motors respond to changes in vehicle pitch.
When the car accelerates hard, climbs a steep grade, or carries extra weight in the rear, the headlights can otherwise point higher than intended. The software counters that movement in real time so the beam stays aimed at the road surface rather than into the eyes of other drivers.
Early indications reveal the update is reaching a limited set of vehicles, including certain Model 3 and Cybertruck examples in the United States and the United Arab Emirates. The rollout does not appear tied to a single hardware revision, and Tesla has not published a broader schedule. It is simply a common waiting game until your car receives it.
The change arrives against a backdrop of wider complaints about headlight glare. Some earlier Model 3 and Model Y vehicles were the subject of an NHTSA recall related to excessive low-beam glare; the software adjustment offers a potential mitigation for cars equipped with the necessary leveling hardware. It does not replace adaptive high beams where those are already available, nor does it alter the basic low-beam pattern itself.
Instead, it keeps an existing beam pointed where it is most useful.
For drivers who have received the update, the system requires no new settings or user input. The headlights simply respond as road conditions and traffic change. As the feature reaches more vehicles, it adds another example of Tesla using over-the-air software to refine existing hardware rather than waiting for a new model year. Nighttime visibility and reduced glare for others are the practical results owners are expected to notice first.

Tesla teases “Halloween Mode” update with Optimus rising from a graveyard
Tesla’s Halloween teaser hides a covered vehicle and an Optimus hand rising from the ground.
Tesla has started teasing a Halloween software update for its vehicles, with a short clip on X that reads, “Halloween is coming.” The clip opens on a glowing pumpkin before pulling back to the car’s center touchscreen, where the usual parked visualization has been replaced by a graveyard scene, and the vehicle draped with a white sheet so it reads as a cartoon ghost.

The second detail is a robotic hand clawing its way out of the dirt like a zombie, which looks to be the hand of Tesla’s latest Optimus V3 humanoid robot. While Tesla still has not formally shown Optimus Gen 3 walking around in service, renders pulled from Tesla’s Android app last month gave the clearest look yet, including far more refined hands that Tesla has said carry 22 degrees of freedom. The hand has been the hardest part of the program. Musk has called it the majority of the robot’s engineering difficulty, and Tesla’s patents describe a design driven by tendons with the actuators moved into the forearm.

Optimus also has a Halloween track record. Last October the robot handed out candy in Times Square, and a costumed “zombie” Optimus shuffled around the Tesla Diner in Los Angeles on Halloween night.
On the software side, Tesla’s 2025 Holiday Update expanded Santa Mode with a Santa sleigh, snowmen, snow effects, and a festive lock chime, so it wouldn’t be too far fetched if we saw something similar but themed for a Halloween Mode.
Tesla Full Self-Driving is set to receive improvements to address its two biggest issues, according to a company engineer.
Director of Engineering at Tesla AI, Phil Duan, revealed in a post on X that improvements to both pothole avoidance and navigation “are coming,’ something we have heard many times in the past. However, there are a few things that seem to hint that things might be different this time around.
Improvements on both are coming.

Pothole avoidance, navigation, speed control, and left lane camping are some of the most prevalent and frequently mentioned shortcomings of the Full Self-Driving suite. These are a few of the biggest issues that have kept Tesla Full Self-Driving as a Supervised suite, meaning drivers must remain attentive during operation.
Pothole Avoidance
Pothole avoidance was first mentioned as an “Upcoming Improvement” with the Tesla Full Self-Driving v14.3 update back in early April of this year. It was listed alongside “Expand reasoning to all behaviors beyond destination handling.”
It’s been six months since we first saw pothole avoidance explicitly mentioned, and it has not moved beyond that and joined the main release notes yet.
Tesla has not shed any light on why pothole avoidance has been such an issue for it to solve, but it also has issues identifying large bumps much of the time, so its modeling of sudden changes in road conditions is likely pretty weak at this particular point. I’ve had more issues with large bumps than potholes, personally, but both are issues that need to be resolved.
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

It makes sense that things might be pretty close to being released to the public, as we are going on such an extensive period of time between it being mentioned and it actually being deployed.
Navigation
Navigation is likely the most painful part of using Full Self-Driving, as it routinely takes strange routes, has trouble with local rules (like Except Right Turn Stop Signs in Pennsylvania), and sometimes does not realize that maneuvers it is suggesting are against the law. Turning out of my neighborhood, you cannot turn left, yet my Model Y still suggests it roughly 70 percent of the time when I’m leaving.
However, Tesla might be close to a breakthrough on this. With the Summer Update, Tesla added “Preferred Routes” alongside “Automatic Navigation.”
Preferred Routes prioritized roads that the driver had actually taken before, instead of always defaulting to what the vehicle believes is the most efficient path. This has already solved many of my issues. Formerly, I would turn off the Online Routing setting, and that would eliminate most of my complaints with routing, but then you lose out later on the Live Traffic Visualization.
Tesla’s Navigation has improved tremendously thanks to the Preferred Routes release with the Summer Update, but it still could use some polishing, as it still suggests strange routes from time to time, and it also has a lot of issues getting out of a parking lot. I find that those truly confuse FSD sometimes.
