Most Common Tesla Parts That Need Replacement

Imagine this: you’ve had your Tesla for just 20,000 miles, and suddenly the tires are worn out—or your touchscreen freezes mid-drive. While Teslas are known for requiring far less maintenance than traditional gas-powered cars, they aren’t completely free of repairs. Some parts wear out faster than others, and being prepared can save you both time and money.

In this guide, we’ll break down the most common Tesla parts that need replacement, why they wear out, and what you can do to keep your EV in top condition.

Why Tesla Parts Still Wear Out

One of Tesla’s biggest selling points is reduced maintenance. With about 20 moving parts in the drivetrain compared to 2,000+ in gas cars, Teslas eliminate headaches like oil changes, spark plugs, and muffler issues.

But here’s the catch: Teslas are heavier than most cars because of their massive battery packs. That added weight, combined with instant torque and complex electronics, means some parts are under more stress than in conventional vehicles.

That’s why knowing the most replaced Tesla parts is essential for every owner.

Categories of Tesla Parts That Commonly Need Replacement

Let’s break it down into three main categories: wear-and-tear parts, electrical & tech components, and glass & exterior items.

 Wear-and-Tear Parts

1. Tires

No surprise here—tires are the most replaced Tesla part. The extra weight of the battery and powerful acceleration mean faster wear. Most owners replace Tesla tires around 20,000–25,000 miles, compared to 40,000 miles on standard vehicles.

Pro Tip: Rotate your tires every 6,000–8,000 miles to extend their life.

2. Suspension (Control Arms, Bushings, Ball Joints)

Tesla’s smooth handling comes at a price: suspension components wear out faster due to added stress. A clunky or squeaky ride is often the first sign.

3. Brake Pads & Rotors

Thanks to regenerative braking, Tesla brakes last longer—often around 70,000 miles. But corrosion from moisture and eventual wear still require replacements.

 Electrical & Tech Components

4. 12V (Low-Voltage) Battery

While the main lithium-ion battery can last hundreds of thousands of miles, Teslas still rely on a 12V auxiliary battery to power systems like lights and locks. These typically last 3–5 years and will need replacing at least once during ownership.

5. Touchscreen (MCU – Media Control Unit)

The touchscreen is Tesla’s “command center.” Older models (MCU1) suffered from memory chip failures, leading to frozen screens or shutdowns. Tesla has improved hardware, but the MCU remains one of the most replaced Tesla parts.

6. Headlights & Taillights

Moisture buildup and LED failures are common. Replacements are straightforward, and high-quality alternatives are available through trusted suppliers.

 Glass & Exterior Items

7. Windshields & Glass Panels

Teslas feature expansive glass designs, from panoramic roofs to oversized windshields. That makes them beautiful—but also more vulnerable to cracks and chips. The Model X windshield, in particular, is one of the most frequently replaced.

8. Door Handles (Model S & Model X)

Tesla’s sleek retractable door handles look futuristic but are prone to motor or sensor failures. They’re infamous for being one of the most common repair issues.

9. HVAC System (Cabin Filters & Compressors)

Cabin air filters need replacement every 2–3 years, depending on the model. Some owners also experience compressor issues in older Teslas.

10. Half Shafts & Drive Units

High-performance driving takes a toll. Half shafts (axles) and drive units sometimes fail in Model S and Model X due to repeated hard acceleration. While less common than tires or batteries, they’re worth mentioning.

Key Tesla Repair Statistics

• Tires: Owners replace them 30–40% sooner than on gas-powered cars.
• Suspension: Many Model S/X drivers report repairs within 60,000 miles.
• Touchscreens: Tesla recalled 135,000 vehicles in 2021 due to MCU memory chip issues (NHTSA).
• 12V Battery: Nearly all Tesla owners will replace it at least once.

Where to Get Reliable Tesla Replacement Parts

Tesla service centers can be pricey, and parts may take weeks to arrive. That’s why many owners choose third-party marketplace like Sexy EV Parts.

They offer a wide selection of Tesla replacement parts—from headlights and control arms to HVAC filters—without the long wait. Whether you’re a DIYer or working with a local mechanic, sourcing from a reliable supplier keeps your Tesla on the road longer.

Tips to Extend the Life of Tesla Parts

Here’s how to cut down on unnecessary replacements:

• Rotate Tires Regularly: Every 6,000–8,000 miles.
• Check Suspension Early: Address squeaks or vibrations before damage spreads.
• Maintain HVAC System: Replace filters on schedule to protect the compressor.
• Protect Glass: Apply windshield protection film to reduce chip risks.
• Stay Updated: Install Tesla’s latest software updates, which often fix performance bugs.

Pro Tip: Keeping a small stock of essentials—like filters or bulbs—from Sexy EV Parts can save time and prevent last-minute stress.

Final Thoughts

Teslas may need less maintenance than gas cars, but they’re not immune to wear and tear. The most common Tesla parts that need replacement include tires, suspension components, 12V batteries, brake parts, door handles, and touchscreens. Understanding why these parts fail helps you plan, budget smarter, and avoid unexpected downtime.
