Reaching 100,000 miles in your Tesla is a milestone worth celebrating. But it’s also a critical point to check in with the health of your vehicle. While Tesla vehicles are known for having fewer moving parts than traditional gas-powered cars, that doesn’t mean they’re maintenance-free, especially after the 100K mark. Understanding what to expect and where to go for reliable Tesla repair services can save you from costly surprises down the road.

Let’s take a closer look at what kind of attention your Tesla may need once it hits 100,000 miles.

Tesla at 100K Miles: What to Expect

Owning a Tesla comes with fewer traditional maintenance tasks, but 100,000 miles is still a major milestone. At this point, parts that have worked quietly for years may begin to show wear. EVs like Tesla require a different kind of maintenance compared to gas-powered cars. Here’s what Tesla owners should focus on after hitting the 100K mark.

1. Battery Health Check

Tesla batteries are designed to last, but gradual range loss is expected over time. Most retain about 90% of their original capacity at 100,000 miles. Testing battery health can reveal changes in range, charging speed, and thermal regulation. A battery diagnostic ensures your Tesla is still delivering reliable performance.

2. Brake System Inspection

Regenerative braking helps Teslas go longer between brake pad replacements. Still, after 100,000 miles, it’s smart to inspect pads, rotors, fluid, and sensors. Brake fluid should be replaced every 2–3 years to avoid moisture buildup and corrosion. Ignoring brake maintenance could compromise stopping power and safety.

3. Suspension and Steering Review

Suspension parts wear gradually and may affect ride comfort or steering precision. Key components like control arms, bushings, and shocks should be inspected at 100K. Symptoms of wear include clunking sounds, uneven tire wear, or loose handling. Addressing issues early helps maintain ride quality and safety.

4. Battery Coolant Replacement

Tesla’s cooling system keeps the battery operating at safe temperatures. Coolant typically needs to be changed every 5 years or around 100,000 miles. This service involves careful bleeding and refilling to avoid air pockets. Skipping coolant maintenance can lead to overheating and battery degradation.

5. Cabin Air Filter and HVAC Service

Tesla recommends changing the cabin air filter every 2 years, but it’s often overdue by 100K. A clogged filter can reduce airflow and cause bad odors. Servicing the HVAC system also helps eliminate mold or debris buildup. Clean filters and functioning HVAC systems ensure a healthy, comfortable cabin environment.

6. Drivetrain and Motor Inspection

Even though Tesla motors are low-maintenance, they should still be checked at this mileage. Components like drive units, CV joints, and axle seals can develop wear. Look out for vibrations or noises during acceleration as signs of trouble. Preventive inspection ensures continued smooth and silent operation.

7. Software and System Diagnostics

Tesla software updates happen automatically, but diagnostics still matter. A full system scan can reveal hidden faults, sensor issues, or lag in infotainment systems. Safety features like Autopilot should also be checked and recalibrated if needed. Keeping software and systems up-to-date supports vehicle performance and safety.

8. Tires and Wheel Alignment

Tires usually don’t last 100,000 miles, so replacement may be due. Uneven tire wear or road noise might indicate alignment problems. Fresh tires and a proper alignment improve traction, range, and comfort. Regular tire service also helps protect suspension components from additional strain.

5 Essential Tips to Keep Your Tesla Running Smoothly Beyond 100,000 Miles

1. Stay Ahead with Scheduled Maintenance

Even though Teslas have fewer moving parts, routine checks are still critical. Follow Tesla’s recommended maintenance timeline for items like brake fluid, coolant, and cabin filters. Don’t wait for problems to appear—prevention is cheaper than repair. Scheduling periodic inspections helps catch issues before they escalate.

2. Monitor Battery Performance Regularly

Keep an eye on your vehicle’s range, charging habits, and battery temperature. Use the in-car diagnostics or Tesla app to track battery health over time. Avoid frequent supercharging and extreme temperature exposure to preserve longevity. If you notice a drop in performance, have the battery tested.

3. Rotate Tires and Check Alignment

Tire wear can creep up unnoticed and affect handling, efficiency, and safety. Rotate your tires every 6,000–8,000 miles and check for uneven wear patterns. Misalignment can damage suspension parts and reduce range. Staying on top of tire care improves your Tesla’s ride and lifespan.

4. Don’t Ignore Suspension Noises

Clunks, squeaks, or vibrations from the suspension system are signs something’s wearing out. Get unusual noises checked before they lead to more expensive repairs. High-mileage Teslas often need new bushings, control arms, or shocks. Early attention saves both money and performance.

5. Keep Software Updated and Calibrated

Tesla’s over-the-air updates improve performance and fix known issues, but full diagnostics are still important. Ensure Autopilot, sensors, and safety systems are calibrated correctly, especially after repairs or tire changes. Inconsistencies in system behavior can signal deeper issues. 

A quick scan can catch problems before they affect driving.
