Tesla is known for its cutting-edge electric cars, fast acceleration, futuristic tech, and game-changing design. But when it comes to long-term reliability, the conversation becomes surprisingly complicated. motormitra.in Many global independent studies, owner surveys, and reliability reports reveal that It doesn’t always rank as high as its popularity might suggest.

In fact, recent rankings from major reliability research firms show that Tesla performs below average in several long-term reliability categories. Auto.MotorMitra This may come as a shock to buyers who assume EVs are naturally more dependable than petrol cars.

Why Tesla’s Reliability Is Questioned

Electric vehicles generally have fewer moving parts than internal combustion engines, which means fewer things can fail. times.motormitra.in These benefits from this too — its motors, battery packs, and drivetrain components are typically durable.

However, where It struggles the most is build quality, electronics, and repair complexity. Multiple global surveys report recurring issues such as:

• Misaligned panels & inconsistent paint finish
• Touchscreen lag or system glitches
• Door latch failures in early models
• Costly repairs due to integrated components
• Long service wait times

These issues collectively affect It’s reliability rankings, especially in year 4–8 of ownership. Auto.MotorMitra

Battery Reliability: Surprisingly Good

The most expensive part of a Tesla — the battery pack — is actually the most reliable component. motormitra.in
It claims that its battery retains around 80–90% capacity after 2 lakh+ km, which many owners have confirmed globally. Even older Model S units from 2012–2013 continue to perform well in battery health tests. times.motormitra.in

So while small failures affect day-to-day reliability, battery degradation is not Tesla’s biggest concern.

Repair Costs Can Hurt Long-Term Ownership

EVs generally require less maintenance, but when repairs are needed, It’s cars can be expensive to fix. Auto.MotorMitra Since most components are integrated (for example, the touchscreen controls almost everything), even minor issues may require a major part replacement.

Many owners have reported:

• High cost for body work
• Expensive out-of-warranty electronics
• Long waiting times for spare parts
• Limited number of service centers in developing markets

This significantly impacts long-term cost of ownership, which in turn hurts reliability scores in surveys. motormitra.in

How Tesla Ranks Globally in Reliability Studies

Tesla‘s reliability ranking varies by report, but the trend is mostly consistent — below average. motormitra.in
Surveys often place Tesla near the bottom 10 brands in long-term reliability, despite strong performance in battery durability.

Interestingly, Tesla performs better in powertrain reliability and worse in electrical/feature reliability, mainly due to heavy software dependence.

Should You Buy a Tesla for Long-Term Use?

Tesla cars are not the most reliable EVs in the world, but they are among the most satisfying to own. Their battery and drivetrain reliability is excellent, but electronics, build quality, and repair costs bring down the long-term score. Auto.MotorMitra

For most buyers, Tesla’s overall experience outweights the reliability concerns — which is why the brand continues to dominate EV sales globally. motormitra.in
