What Problems Does the 2021 Tesla Model 3 Have?

The 2021 Tesla Model 3, while popular, has exhibited certain frequently reported problems. Build quality inconsistencies remain a common complaint, including misaligned panels, paint imperfections, and issues with interior trim. The touchscreen, while innovative, is prone to glitches and can be distracting for some drivers, as almost all vehicle controls are integrated into it. "Phantom braking," where the car abruptly brakes for no apparent reason when using Autopilot, continues to be reported.

Recalls have addressed various issues, including problems with suspension components, seat belt anchorages, and malfunctioning rearview cameras. Owners have also reported issues with the heat pump in colder climates, leading to reduced heating performance. Long-term reliability is still being assessed, but some concerns revolve around battery degradation over time, motor durability under heavy use, and the cost of repairing complex electronic components. Earlier model years (2017-2019) generally had more reported issues compared to the 2021, but some quality control concerns persist across all model years of the Model 3.

How long will the 2021 Tesla Model 3 last?

With proper maintenance, the 2021 Tesla Model 3 can realistically achieve 200,000+ miles or 10+ years of service. Battery health is a key factor; regular charging to 80-90% capacity rather than 100% helps prolong battery life. Long-term durability depends heavily on driving habits and climate. Weaknesses over time might include gradual battery degradation, requiring eventual battery replacement (a significant expense). Suspension components and other wear items will also require replacement, as with any vehicle. The touchscreen's longevity is also a potential concern due to its constant use.

What Technology & Safety Features are Included?

The 2021 Tesla Model 3 boasts a high level of built-in tech. The centerpiece is the 15-inch touchscreen controlling navigation, climate, entertainment, and vehicle settings. Entertainment features include streaming services (Netflix, YouTube), internet browsing, and arcade games when parked.

Standard driver-assistance features include Autopilot, which provides automatic emergency braking, lane keeping assist, and adaptive cruise control. Optional upgrades include Enhanced Autopilot (automatic lane changes, navigate on Autopilot) and Full Self-Driving Capability (traffic light and stop sign control, automatic city street driving - still in Beta).

Safety features are comprehensive, including multiple airbags, stability control, and anti-lock brakes. The Model 3 has achieved excellent crash-test ratings from both NHTSA (5-star overall) and IIHS (Top Safety Pick+). It features a reinforced battery pack to protect against intrusion in a crash. Over-the-air software updates continuously improve vehicle performance and add new features.

2021 Tesla Model 3 Prices and Market Value

The 2021 Tesla Model 3 had a starting MSRP of around $40,000 for the Standard Range Plus, climbing to approximately $60,000 for the Performance trim. Used market prices currently range from approximately $30,000 to $50,000, depending on trim, mileage, and condition. Depreciation has been relatively low compared to traditional gasoline cars due to strong demand for EVs and Tesla's brand reputation. Factors affecting resale value include battery health, mileage, Autopilot options, and overall condition. Tesla's Supercharger network access also adds to its value.

2021 Tesla Model 3 Cost of Ownership

Insurance costs for the 2021 Tesla Model 3 can be higher than average due to its complex technology and repair costs. "Fuel" costs (electricity) are significantly lower than gasoline. Maintenance is generally lower due to fewer moving parts. However, repairs, especially involving the battery or electronics, can be expensive. Overall, the Model 3 can be economical in the long run due to lower fuel and maintenance costs, but initial purchase price and potential repair bills should be considered.

2021 Tesla Model 3 Insurance

Insurance for a 2021 Tesla Model 3 is moderately priced, reflecting its status as a Passenger Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2021 Tesla Model 3 Compare to Other Passenger Sedan?

The 2021 Tesla Model 3 competes with EVs like the Chevrolet Bolt, Ford Mustang Mach-E, Hyundai Kona Electric, Polestar 2, and BMW i4. In terms of performance, the Model 3 Performance excels in acceleration, outpacing most rivals. Features-wise, Tesla's Autopilot system and extensive Supercharger network are significant advantages. However, the Model 3's reliability has been questioned compared to some competitors.

The Mustang Mach-E offers a more traditional SUV-like driving experience and comparable range, and is a similarly priced alternative. The Polestar 2 boasts a more luxurious interior and build quality, but at a slightly higher price. The Hyundai Kona Electric offers excellent value and range at a lower price point, but lacks the Tesla's performance and charging infrastructure. The BMW i4 has excellent driving dynamics and interior, but is more expensive. If reliability is a top priority, the Hyundai or potentially the BMW (depending on the user needs) might be a better alternative.

Final Verdict: Is the 2021 Tesla Model 3 a Good Passenger Sedan?

The 2021 Tesla Model 3 is ideal for tech-savvy individuals who prioritize performance, long range, and access to a reliable charging network. It's worth buying if you understand the potential build quality and service limitations. Buying used can offer significant savings, but carefully inspect the battery health and vehicle history. The Long Range trim offers the best balance of range and performance for most buyers. If budget is a concern, a used Standard Range Plus could be a good option. If you need a luxury car, alternatives might be better, and be prepared for sometimes lengthy repair times.

This car has been the best I’ve owned so far.

This car has been the best I’ve owned so far. Even if you aren’t looking at a Tesla, EVs in general are so much fun! I’ve had little maintenance in the three years I’ve had this car so far (tire rotations, wiper blades). Every major software update brings either new features or improvements.

Two years and no issues

If you want a maintenance-free vehicle, this is the closest thing you can find on the market. We’ve been driving the wheels off our Model 3 LR for almost two years. No gas stations, no oil changes, no fluid changes (unless you count windshield wiper fluid,) tires still have plenty of tread, brakes have barely ever been used (regenerative brakes are amazing,) the temperature in the car is always perfect when you get in, and no turning the car off, simply get out and walk away, the car does the rest. The only service we have done to this car has been tire rotation, and they come to your house to do it if you want! Charging at home means you never, ever have to worry about the state of your ā€œtankā€ unless you’re on a trip over 350 miles. And then it’s a quick navigation to a supercharger for a few minutes; the car automatically does the math for you and determines the best places to stop along your route. Admittedly, the occasional supercharge on a long trip is the only downside and could be a dealbreaker for some. But we plan accordingly. Plug up the car, walk the dogs or grab a bite to eat. By the time you’re done, the car is ready to go! The loudest voices in the room are always the people that had the rare bad experience, that’s inescapable. Just know that they are the minority. This car has plenty of get up and go whenever you need it and rides smooth. I used to drive muscle cars, so not hearing all that engine noise took a little bit to get used to. But now I don’t miss it at all. In fact, now I’m mildly annoyed when I’m the passenger in a loud car. That’s probably also a sign that I’m getting older. If you’re on the fence about an EV, go take one for a test drive. Tesla doesn’t pressure you, they don’t even ride along with you. It’s just you and the car, so you can see for yourself. That’s all it took for us to bite. I can almost guarantee you’ll want one after you’ve driven around in one for fifteen minutes.

Such a fun car

This is easily the most fun car I've ever driven; handling is great and it destroys muscle cars off the line! Very techy but fairly simple to figure everything out. I'll likely only ever buy Teslas now.

Nice toy but not a proper car

Its a good car to drive. Interior for driver is nice but not always convenient while driving. Down sides. Adaptive wipers are nice when they work, but you cannot adjust sensitivity and changing to manual is from screen. Cruise control quite often slows down or even panic brakes for no apparent reason. Also sometimes changes speed above speed limit even when settings are to hold speed that I was driving. Basically everything is done from touchscreen in middle that is no good while driving. This includes light, wiper and other settings we are used to control while hands on wheels. Good things. Acceleration is great when you need it.

Converted me to EV

It's the first time I've actually enjoyed driving. Before this I had a Civic, then a Sonata, and my first car way back was a Chrysler 300 (which was an absolute heap of garbage). After the 300 I was purely interested in reliable, economical cars that would get me from A to B with the basic amenities. The Model 3 was a step way above that, it's more efficient than any gas-powered or hybrid commuter car, it has a modest stylishness to it, and it has WAY more get-up-and-go than you'd expect, even with the single-motor package. The torque is instantaneous with no dead zones or gear changes. The handling is solid. There's a lot to love, including the infotainment system, built-in navigation, huge screen, etc. It was a lot to adjust to, going from a vehicle with tons of dials and buttons to just a screen and a handful of tactile controls, but I love it now. But one of the things I love most about it is that I can just open my phone and start the AC a couple minutes before I get in my car - In a city that regularly sees 110+ degrees, that is a GODSEND. I'm definitely an EV convert after buying a Model 3.

Long lasting, Safe, Easy

Riding in this car will make you feel like you are a part of the future or hovering aboard a space ship. It truly rides like magic. I’m amazed at what this vehicle can do. The reliability and safety of this car is outstandingly outperforming every other car on the road. It does not require maintenance and every bit of the vehicle was built to guide humanity in the direction of 100% safe transportation. From my calculation on battery life, this vehicle will still hold a 250 mile charge after it’s been on the road for 600,000 miles. Considering sustainability of electricity and cost to charge- this car will save your pocket on energy costs and the earth from fuel emissions. The simplicity of the vehicle makes it easy to keep clean! Perfect 10/10 car.

Have to find a new owner for it.

Mileage is only an Estimate. Charged for a trip in the winter and it planned out the course to a supercharger, and beyond, only to find that we had next to 1 mile left when we arrived. 175 miles away, with a 258mile charge...stressful. Another problem, service. Our ambient temp sensor went south, reads -39F in the 90 degree weather, turns on the defrosters, seat heaters, and won't run the AC. Tried to fix, but the FRUNK won't open at all. Tesla service will fix it, but we have to bring it to one of 4 "local" state wide service areas an hour plus away. And, the appointment was a month out. Have had basically a $45k brick in our driveway for pretty much a month. Oh, also, they don't answer the phone and don't work on weekends. Come on Elon...fix your service, we need our cars.
