Does Mileage Matter on a Tesla: What You Need to Know

Tesla’s battery life is one of its most talked-about features. With battery warranties typically covering 8 years or 100,000 to 150,000 miles, Tesla has set industry standards. However, many Tesla owners report their vehicles exceeding these benchmarks with minimal issues. Factors influencing battery longevity include:

• Charging Habits: Using a EV charger Level 2 to regularly charge to 80% or 90% capacity, instead of 100%, can prolong battery health. Overcharging and frequent fast charging can lead to faster degradation. Charging from 20% to 80% typically takes around 45 minutes, while charging from 80% to 100% can take over an hour. Many users observe that Supercharging above 80% is inefficient, as charging speeds slow significantly, making it a less time-effective option. Adopting these practices helps maximize battery longevity and efficiency.

• Climate: Extreme cold or heat can accelerate battery wear. Tesla’s thermal management systems mitigate some of these effects.

• Driving Conditions: Aggressive driving and frequent use of full acceleration can impact battery efficiency over time.

• Moisture Protection: Keeping moisture out of the battery and drive unit is essential. Entrapped moisture can cause internal damage.

Many high-mileage Tesla owners share success stories of vehicles surpassing 100,000 miles with minimal degradation. Some are reporting 144,000 miles with only an 8% battery degradation, while others have driven over 300,000 miles with a power reduction of just a little over 10%.

This minimal degradation in Tesla EVs is mainly due to an efficient battery management system (BMS). It continuously monitors parameters to prevent overcharging, overheating, and other conditions that accelerate wear and impact battery capacity.

The Impact of High Mileage on a Tesla

As with any vehicle, high mileage introduces wear and tear. For Teslas, common issues include:

• Tire Wear: Due to their high torque, Teslas often wear out tires faster than ICE vehicles. Frequent replacements may be necessary.

• Brake Longevity: Teslas’ regenerative braking extends the life of brake pads, often lasting well beyond 100,000 miles.

• Other Components: Items like retractable door handles, LCD display screens, and sliding armrests may require replacement over time. Some owners also report issues with drive units, frunk latches, and moisture intrusion into external lights.

Despite these issues, many Tesla owners emphasize the reliability of their vehicles. Unlike other electric car models, Tesla promises a smooth run even after 200,000 miles, with original batteries and minimal power degradation. The aluminum body of Teslas also remains rust-free, maintaining aesthetic appeal even after years of use.

Evaluating a Used Tesla: More Than Just a Car

When assessing a used car, specifically, Tesla, it’s crucial to look beyond mileage. Factors such as battery health, maintenance records, and overall condition are more significant indicators of value and reliability:

• Battery Health: The battery’s state of charge and degradation percentage provide a clearer picture of its condition than mileage alone.

• Maintenance Records: Comprehensive service histories show how well the vehicle has been cared for.

• Exterior and Interior Condition: Check for wear and tear, especially on frequently used components like seats and handles.

While Teslas are known for their low maintenance costs, certain components, like battery packs, can be expensive to replace. A new battery module can cost between $20,000 and $35,000. Ensuring the battery is in good health can save significant future expenses

How Many Miles is Too Many?

High mileage on a Tesla doesn’t carry the same risks as it does for ICE vehicles. A traditional gas car relies on complex engines and transmissions, which degrade significantly over time. In contrast, Tesla’s electric motor is designed to operate with minimal maintenance and near-indefinite longevity. However, battery health becomes a key factor as mileage increases. The battery pack gradually degrades, with most Tesla owners reporting a capacity loss of 10-15% after 150,000 miles, which still allows for considerable driving range.

One unique aspect of Tesla’s engineering is its use of regenerative braking, which reduces wear and tear on brakes from traditional braking systems. Owners of Teslas with over 200,000 miles often report that the original brake pads are still in good condition, something unheard of in ICE vehicles. Additionally, the lack of internal combustion-related components eliminates the risk of costly engine or transmission repairs that frequently plague older gas cars

Battery Degradation

Battery degradation varies depending on factors like charging habits, climate, and driving style. While some high-mileage Teslas show minimal capacity loss, others may experience noticeable reductions, especially if subjected to extreme conditions or frequent use of Electric vehicle chargers not optimized for long-term battery health. For instance, Teslas in hot climates or those frequently charged to 100% may show slightly faster degradation. Despite this, even older Teslas often maintain around 70% of their original range after exceeding 150,000 miles, aligning with Tesla’s warranty promise.

Practical Tips for Evaluating High-Mileage Teslas

If you’re considering a Tesla with over 100,000 miles, there are several steps you can take to ensure it remains a reliable investment:

• Battery Degradation: Request a battery health report. For vehicles frequently charged with a EV charger Level 1, look for degradation under 10-15%, as these will retain much of their original range.

• Warranty Coverage: Check if the vehicle is still under its original battery and drivetrain warranty. If not, consider an extended warranty for added protection.

• Professional Inspection: Have a Tesla-certified technician or service center conduct a comprehensive inspection, including the battery, drivetrain, and other high-wear components.

• Maintenance Records: Ensure the vehicle’s service history is complete and includes any necessary repairs or software updates.
