Tesla Model S Battery Failure -A Complete Guide 2024

Tesla Model S Battery Failure

If the main battery is exhausted, it is unlikely that the 12 V auxiliary battery will also be damaged. Tesla Model S battery performance can cause fire and battery failure. The low power mode of the Tesla Model S battery is active, the 12V auxiliary battery in the Li-ion battery is no longer charged and can be fully discharged within 12 hours. What is Tesla model S battery Failure?

The Tesla Model S battery failure will happen when it has lost 20% of its range. Most users report Tesla losing battery only 5-100,000 miles. In the unlikely event this happens, you may have to start or replace the 12V battery before it can be charged. The battery range of the Tesla Model S has been reduced from the original 264 miles (425 km) to 248-250 miles (about 400 km). This equates to a 6% battery drop over 9 years, a very impressive number.

When this low power mode is activated, it is important to keep the Model S plugged in for two months to avoid damaging the battery.

Electric vehicles don’t have clutches or torque converters, so the Tesla Model S is always mechanically connected to the wheels. Putting a Tesla in neutral will de-energize the Tesla Model S and release the electric handbrake.

The AC discharge hose is located on the steel cover of the fuse box. When water gets into this area, the casing will rust and allow water to enter the battery, causing it to fail over time.

Tesla Model S Li-Ion Batteries Li-Ion batteries in electric vehicles are a big no-no because they know that the same batteries in cell phones and laptops don’t last long. The problem is that they are not the same type of battery.


Brief History of Tesla Model S Battery Issues

The lithium-ion battery in the Tesla Model S gradually loses capacity over time. A key question for Model S owners, who have high battery replacement costs, is how much it will cost.

Tesla is one of the most popular electric car models on the market. With nearly 300,000 vehicles sold in 2020 alone, he holds more than 42% of the EV market share.

Over the past few years, Tesla, Inc. has built a strong reputation for building the highest rated, most energy efficient vehicles ever built.

But even Tesla, which has a reputation for building the most reliable vehicles, is not without its problems. Recent reports indicate that drivers are experiencing battery issues in Tesla Model S and Model X vehicles.

Tesla Model S or Model X owner, this rule may not be your only option. Read below to learn more about Tesla Model S and Model X battery issues and your potential legal choices as a Tesla owner or lessee.

Problem with Tesla Model S Battery

The Tesla company has confirmed to the media that an over-the-air software update is temporarily limiting the maximum battery capacity and range of its 1,743 Model S.

A Model S driver reported noticing a noticeable difference in both battery performance and battery life in his Tesla Model S car shortly after Tesla released a software update in his 2019.

By October 2019, Tesla was working toward a settlement agreement, and her lawyers continued litigation over the matter.

Tesla software updated to address software and battery issues, allowing affected Tesla owners’ vehicle batteries to recover while the driver continued to drive the vehicle. restored to maximum voltage over time.

According to documents filed in the United States District Court in San Francisco in that lawsuit, the proposed settlement would allow TeslaInc.

To pay $150 to a fund allocated to Tesla Model S owners (and other Tesla owners). You will pay $10,000 and will be affected by this software. and battery issues.

Including legal fees, the settlement amount is equivalent to paying $625 to Model S drivers affected by this software update and the associated battery issues.

Causes of Tesla Model S Battery Failure

Mario Zelaya bought his brand new 2013 Model S Performance almost ten years ago. He drove it 124,204 km (77,177 miles) until it crashed on March 8, 2022.

A few days later, the owner of this Tesla learned that he would have to pay $28,684.83 CAD for a few battery replacements. months after the warranty expires. Zelaya has asked Transport Canada for help and is now accusing Tesla of hiding a critical design flaw.

The Model S battery failure isn’t new but Zelaya’s case may shed some light on the problem. Tuomas Katainen had only driven his used 2013 Model S 1,500 km (932 miles) when the error code appeared.

The diagnosis he received was the same as a damaged battery, which will require replacement for €20,000 – $19,934 at current exchange rates.

Katainen decided to blow up his electric sedan, something the Canadian Tesla Model S owner considered until he found a final solution to his situation.

The Tesla service center told him it would cost him US$21,785 to replace the battery. which is under warranty until 2024.

Tesla claims “the car was flooded,” but Campbell says that never happened. You should know this: The EV has been parked in his garage since he bought it in September 2016.

So What Could Cause the Battery to Appear to be Flooded? You will soon understand how these two stories connect.

Electric vehicle problems went viral, and we reached out to him to find out everything that led him to believe Tesla was hiding problems with Model S batteries.

Tesla, the situation began when he received a warning about a high voltage failure while driving his electric sedan to work in Burlington, Canada. 

How to Prevent Tesla Model S Battery Failure

A Tesla Model S had a failed battery, and one owner picked up the automaker’s all-electric flagship sedan for a theft of $10,000.

However, the car didn’t work, but thanks to technicians from Gruber Motors, the problem was resolved and the Model S was back in action at a bargain price.

A video from the Gruber Motor Company YouTube channel revealed a simple process by garage technicians to restore a Model S battery. Instead of handling the replacement through one of Tesla’s service centers for a fee. 

How to Revive an Old Model S Battery?

Teslas, like any other vehicle, need routine maintenance to keep their powertrains working. 

Unfortunately, while the maintenance of electric cars is significantly lower than that of ICE cars, they still suffer from problems, such as malfunctions and battery failure.

This is a common problem with older Teslas and other electric vehicles, simply because the battery will reach the end of its life at some point during the ownership experience.

Fortunately, Tesla’s battery design allows for simple repairs when one of the more than 7,000 cells fails.

So even if something bad happens to that cell, like it catches on fire or whatever, it gets isolated.

This design allows for frequent replacement of a single cell instead of a complete package consisting of several medium sized cells or even one large cell.

This is exactly what the Gruber Motors team did to deal with the faulty Model S that was brought to them at the end of October. 

Dealing with Tesla Model S Battery Failure

Tesla has invested heavily in making its batteries as reliable as possible without sacrificing performance.

So if you’re worried about Tesla’s battery failure rate: The reason the failure rate of the battery is so low is thanks to the company’s famously advanced technology.

Although alternative energy sources have some advantages over fossil fuels, energy availability remains an important issue.

A proven method to overcome this is to use a high capacity battery with more recharge cycles so it can withstand the elements without affecting its ability to charge.

This requires innovative solutions that maintain a balance between performance and security. The Tesla Model S has been at the forefront of high-tech EV technology.

While people complain about the cost, there’s no denying that Tesla batteries have a lot of potential. 

What’s even more impressive is the Tesla Model S’s battery failure rate.

Why is the Battery Failure Rate so Low?

If you are wondering about this fact, this article will satisfy your curiosity.

Manufactured by Panasonic, the Tesla 1865 type lithium-ion battery includes a nickel-cobalt-aluminum (NCA) cathode.

The battery is made up of several cells fused together to increase its energy density. The 1865 battery is designed for maximum runtime, which is why you’ll find it in versions like the Model S. 

Comparing Tesla Model S Battery Failure to Other Electric Car

Not many electric cars need replacing, but according to Musk, a new battery for a Model 3 car can cost you around $5,000 to $7,000. These prices will drop as the cost of the battery itself goes down.

Complaints from people paying thousands of dollars for a new battery have not been confirmed, and these discussions only add to the conflicting information about battery replacement costs. But Tesla batteries can still go more than 500,000 miles, just less distance per charge.

Also, keep in mind that recharging contributes to battery quality deterioration and can affect its long-term life, especially if you charge it from empty to full on a daily basis.

In fact, Tesla’s battery technology makes your electric vehicle more reliable over time, with studies showing that performance drops only 10 meters after 100,000 miles. So you can expect top performance from your vehicle until then.

In the rare event that your battery fails, don’t worry, as degradation of a Tesla battery is covered under the Tesla warranty policy. 

Warranty coverage will depend on the model, but each covers 8 years or 100,000 to 150,000 miles in range.

Simply put, you can drive your Model Y 15,000 miles per year or 41 miles per day during the 8-year warranty. During this time, Model X and Model S vehicles will travel approximately 18,750 miles per year or 52 miles per day before the warranty expires.

The Future of Tesla Model S Battery Technology

A two-year-old Michigan startup, Our Next Energy (ONE), built a custom battery that recently powered a modified Tesla Model S for 752 miles.

John Voelcker, writing in Car and Driver, reports that the ONE has retrofitted the car with a power reserve pack that doubles as Tesla’s original and fits in the same space.

ONE installed its 207.3 kWh pack in the Tesla Model S Long Range Plus. The original package of the car has a capacity of 103.9 kWh.

Package ONE has a much higher energy density, but its efficiency (measured in miles per kWh) is roughly the same.

It’s an even more impressive feat considering Tesla’s car is one of the most efficient electric vehicles on the road.

ONE drove the modified Model S for about 14 hours at an average speed of 55 mph on a cold December day in Michigan and recorded 752.2 miles. In a dyno test, also at 55 mph, the pack reached an even more impressive 882 mph.

ONE calls its experience with the Model S a proof of concept for a future battery technology called Gemini, which it hopes to put into production after 2023.

LFP Battery 

ONE uses lithium-iron-phosphate (LFP) chemistry, which has previously had a lower energy density than cobalt or nickel-based chemicals.

As for Gemini, the company told Car and Driver that it plans to supplement the lower-cost LFP cells with special “range-extending” cells that will only operate for one percent of the duty cycle. of the vehicle.
