Top Upgrades for Your 2024 Tesla Model 3/Y
Tesla vehicles come loaded with advanced technology, but certain physical comforts and utility features are left for the owner to source. Choosing the right additions ensures your car remains clean, functional, and enjoyable on long road trips or daily commutes. Here are the top six areas new owners should address first.
Tesla Under Screen Storage Box Dual Layer with LED — Maximizing dead space
Why we like it: The gap directly beneath the center touchscreen is a notorious black hole where items disappear. This dual-layer storage box slides perfectly into that space, reclaiming it for everyday essentials. The built-in LED strip illuminates the contents, making it easy to locate items in the dark. A silicone mat at the bottom ensures that your phone, keys, or cards do not slide around or cause rattling noises while driving. It snaps into place without tools, matching the OEM interior trim perfectly.
Who it’s for: Owners tired of cluttered cupholders and losing loose items in the center console area.
Installation: Easy (1/5) | Compatibility: Both Model 3 and Model Y (2017-2023)
Custom-Fit All-Weather Floor Mats — Defending your cabin
Why we like it: Tesla’s factory carpet mats look great on day one but absorb water, mud, and salt quickly. High-quality all-weather floor mats use laser scanning to match the exact contours of the Model 3 and Model Y footwells. They feature raised edges that trap liquid, preventing spills from seeping into the carpet and reaching the floor wiring. Unlike universal mats, custom-fit options secure to the factory retaining posts, ensuring they never slide forward under the pedals.
Who it’s for: Anyone who drives in rain or snow, transports pets, or simply wants to protect their vehicle’s resale value.
Installation: Easy (1/5) | Compatibility: Model Y (2020-2024) or Model 3 (2017-2023); verify fitment for 2024 Highland.
MagSafe Compatible Phone Mount — A secure screen anchor
Why we like it: Although Teslas have built-in navigation, many owners prefer using their phone for music, Waze, or secondary navigation. A high-quality MagSafe mount designed specifically for the Model 3 or Model Y attaches securely to the back of the center screen or the dashboard pillar. This places the phone at eye level without relying on unreliable suction cups that fail in extreme temperatures. Magnetic mounts allow for one-handed operation, easily snapping the phone into place when you enter the car.
Who it’s for: Drivers who rely on their smartphone for streaming audio, Google Maps, or Waze.
Installation: Easy (1/5) | Compatibility: Both Model 3 and Model Y
Retractable Glass Roof Sunshade — Beating the cabin heat
Why we like it: The expansive glass roof on the Model 3 and Model Y creates a beautiful open feeling, but it also turns the cabin into a greenhouse during summer. A retractable sunshade uses a folding mesh frame that slides directly under the glass, blocking UV rays and significantly lowering cabin temperatures. The best versions feature bungee tension mounts that require no drilling, clips, or messy adhesives to stay put, allowing you to install or remove it in under a minute.
Who it’s for: Owners living in warm climates or those who find the interior gets too hot when parked in the sun.
Installation: Easy (2/5) | Compatibility: Model 3 (2017-2023) and Model Y (2020-2024) varies based on specific roof dimensions.
High-Capacity NVMe SSD — Reliable Sentry Mode storage
Why we like it: Tesla’s built-in dashcam and Sentry Mode record video when the car is parked, but they require external storage. While many owners use USB flash drives, these drives are not designed for continuous video overwriting and will degrade quickly. Installing a high-capacity NVMe solid-state drive in the glovebox compartment provides vastly superior endurance, faster video transfer speeds, and enough space to save dashcam footage for weeks without needing to format the drive. It makes pulling footage for insurance or police reports seamless.
Who it’s for: Owners who use Sentry Mode frequently and want to easily save and access video recordings.
Installation: Medium (3/5) | Compatibility: Both Model 3 and Model Y (requires glovebox USB adapter)
J1772 to NACS Adapter — Unlocking chargers everywhere
Why we like it: While the Tesla Supercharger network is vast, there are times when a non-Tesla public charger is the only option available. A J1772 to NACS adapter allows your Model 3 or Model Y to connect to standard Level 2 public chargers found at many hotels, shopping centers, and municipal parking garages. This simple adapter ensures you are never completely locked out of a charging network, providing long-term road trip security and convenience.
Who it’s for: Frequent road trippers and owners who want ultimate charging network flexibility.
Installation: Easy (1/5) | Compatibility: Both Model 3 and Model Y
What to look for in Tesla Model 3/Y accessories
When evaluating upgrades for your vehicle, the minimalist design language of Tesla interiors means that poorly designed accessories stand out like a sore thumb. Here is exactly what to look for to ensure your purchases match the factory aesthetic and perform reliably over time.
Model Year Compatibility
Tesla frequently updates its manufacturing process without announcing major refreshes. The 2024 Model 3 (Highland) has a completely different front bumper, interior layout, and charging port location than the 2020-2023 Model 3. Always verify the exact year and trim compatibility before purchasing items like floor mats, sunshades, or screen protectors. Products designed for older vehicles often will not snap in cleanly or will obstruct newly relocated sensors.
Interior Aesthetics
Your Tesla has a modern, ultra-clean cabin. Avoid accessories that require visible wires running across the dashboard or bulky plastic mechanisms. The most effective additions, like the under-screen storage box, match the factory trim materials and utilize existing Tesla mounting points. The goal is to add function without introducing visual clutter.
Ease of Installation
You should not need to splice wires or permanently modify your interior to add basic utility. The best Tesla upgrades use pressure-fit designs, OEM retaining clips, or slide easily into existing dead space. Difficulty levels of 1/5 are ideal for new owners, while a 3/5 difficulty item like the glovebox SSD usually just requires a few moments to route data cables properly.
Real-World Utility
Focus on items that solve daily friction. Items that hold your phone securely, keep the interior cool without running the AC constantly, or store sunglasses and keys are far more valuable than fad gadgets. As highlighted in our list of accessories we wish we bought sooner, solving small daily annoyances makes the car far more enjoyable.
Frequently Asked Questions
Do I need an SSD for Sentry Mode and Dashcam?
You need a storage drive, but not necessarily an SSD. While a USB flash drive works temporarily, they burn out quickly due to the constant read/write cycles of Sentry Mode overwriting old footage. Upgrading to a proper NVMe solid-state drive in the glovebox is the most robust, long-lasting storage solution for Tesla owners. It requires slightly more installation effort, but the durability is worth it.
Will aftermarket accessories void my Tesla warranty?
No, simply using aftermarket accessories will not void your warranty. Tesla cannot legally void your warranty for adding floor mats, a phone mount, or under-screen storage. However, if an accessory physically causes damage to the vehicle—such as spilling liquids due to a poorly fitting cup insert—Tesla may refuse to cover the specific damage caused by the accessory. Always use products specifically designed for your model.
Are 2024 Model 3 (Highland) accessories compatible with older models?
Rarely. The 2024 Model 3 Highland features a redesigned interior with relocated vents, new door panels, and a distinct center console layout. Items designed for the 2024 Model 3 will generally not fit the 2020-2023 Model 3, and vice versa. The Model Y did not receive this interior update until the Juniper refresh, so accessories remain compatible across older Model Y years, but verifying specific year fitment remains essential.
Whether you are setting up your vehicle for daily commuting or selecting items to keep passengers comfortable on a long trip, the right additions make ownership vastly smoother. You can dive deeper into specific setups by watching the Ultimate Tesla Model 3/Y Owner’s Guide (2024) for visual references.

Bottom Line
Choosing the correct upgrades depends on your specific routine. If you live in a hot climate or park outside at work, prioritizing a retractable glass roof sunshade is the most immediate comfort upgrade. For tech-heavy drivers who want dashcam reliability, transitioning from a cheap USB stick to a high-capacity NVMe SSD is the best long-term investment. Finally, if you are tired of cluttered cupholders and want a seamless interior upgrade, utilizing the dead space with a dual-layer storage box solves the problem instantly without adding visual noise to your Tesla’s minimalist cabin.
