Early Model S Drive Units to Fail by 60k mi, Data Suggests

A survey by Plug In America finds a high drive unit failure rate for 2012 and 2013 Model S cars. It finds that two thirds are likely to fail before 60,000 miles

Weibull analysis of Tesla drive units

Plug In America has completed a survey of owners of 2012 and 2013 Model S cars. A Weibull analysis of the data finds that two thirds of the drive units in those early cars are expected to fail by the time they accumulate 60,000 miles of driving according to Green Car Reports.

The survey collected data from 327 owners and asked each if their drive unit had been replaced and at what mileage. Green Car Reports reporter Matthew Klippenstein found some transcription errors in Plug In America’s raw data. He corrected them and then redid the reliability analysis using Reliasof. The results are slightly more favorable to Tesla and are plotted on the graph below.

Only 43 owners of 2014 and 2105 cars responded to the Plug In America survey and the amount of miles on those cars was well below the threshold for drive unit replacements, so no analysis of that information was performed.

Elon Musk said recently that the company has added automatic grease injection to counteract premature wear issues in the newer drive units, but its impact on reliability won’t be known until later.

Green Car Reports contacted Tesla, requesting answers to these specific questions:

  • How many motors has Tesla repaired or replaced in 2012 and 2013 Model S cars to date?
  • What percentage of total cars does that represent?
  • What does the company’s own reliability data indicate about the percentage of cars that will require motor replacements over the life of the vehicles?
  • Musk said in November that reliability had doubled; how confident is Tesla that it has now fully resolved the reliability issues with earlier motors?
  • What is the company’s projection for failure rate in the motor(s) of current production cars?
  • What would Tesla Motors say to owners (and future used-car buyers) of the early cars regarding the reliability of the motors?

Tesla declined to answer the questions, preferring to rely on a general answer to cover them all. “Close communication with our customers enables Tesla to receive input, proactively address issues, and quickly fix problems. Over-the-air software updates allow Tesla to diagnose and fix most bugs without the need to come in for service. In instances when hardware needs to be fixed, we strive to make it painless.”

The company is reacting positively to reliability issues as they occur. Indeed, Tesla owners report they are very satisfied with their factory service experience. The 8 year Infinite Mile warranty on drive units and batteries means that few owners have suffered out of pocket expense to repair a malfunctioning drive unit.

Tesla Sweden strikers see tax issues over IF Metall union error

To address the issue, IF Metall is encouraging Tesla strikers to return the refunded tax amounts to the union.

A tax correction is set to return two years of income tax payments to Tesla strikers in Sweden, after authorities determined that conflict compensation during a labor dispute should not have been taxed.

The issue is caused by a decision by IF Metall to treat strike compensation for Tesla workers as taxable income during the ongoing labor dispute with Tesla Sweden. That approach has now been reversed following guidance from the Swedish Tax Agency.

Strike compensation is typically tax-free under Sweden’s Income Tax Act, as noted in a report from Dagens Arbete (DA). However, two years ago, IF Metall’s board decided to classify payments to Tesla strikers as taxable.

“We did it to secure SGI, unemployment insurance and public pension. Those were the risks we saw when the strike had already dragged on,” Kent Bursjöö, financial manager at IF Metall, stated.

According to Bursjöö, the union wanted to ensure that members continued to register earned income with the tax agency, protecting benefits tied to income history. At the end of January, however, the Swedish Tax Agency informed the union that compensation during a labor dispute must be tax-free.

“Of course, we knew that it could be tax-free. But we clearly didn’t know that it couldn’t be taxable,” Bursjöö said.

Following discussions with auditors and tax authorities, IF Metall began correcting the payments. As a result, two years of paid income tax will now be credited back to the affected strikers’ tax accounts. The union will also recover previously paid employer contributions.

However, the correction creates secondary effects. Since the payments will now be treated as tax-free, pension contributions tied to those earnings will be withdrawn, potentially affecting state pension accrual and income-based benefits such as parental or sickness benefits.

To address this, IF Metall is encouraging members to return the refunded tax amounts to the union. In exchange, the union plans to pay 18.5% into occupational pensions on their behalf. “Otherwise, it will be a form of overcompensation when they get the tax paid back,” Bursjöö said.

That being said, the IF Metall officer acknowledged that the union’s legal ability to reclaim the funds from its improperly paid Tesla Sweden strikers is limited. “The legal possibilities are probably limited, from what we can see. But we assume that most people see the value of securing their pension,” Bursjöö said.

Tesla sues California DMV over Autopilot and FSD advertising ruling

The complaint seeks to remove the agency’s conclusion that Tesla falsely promoted the capabilities of Autopilot and Full Self-Driving.

Tesla has filed a lawsuit against the California Department of Motor Vehicles (DMV) in an effort to overturn a prior ruling that found the automaker engaged in false advertising related to its driver-assistance systems. 

The complaint seeks to remove the agency’s conclusion that Tesla misled customers about the capabilities of Autopilot and Full Self-Driving.

Tesla’s legal action follows a decision by California’s Office of Administrative Hearings (OAH), which concluded that Tesla’s earlier marketing of “Autopilot” and “Full Self-Driving” violated state law, as noted in a CNBC report. 

While the DMV opted not to suspend Tesla’s license after determining the company had updated its marketing language for its advanced driver-assistance systems, Tesla is asking the court to go further and reverse the agency’s conclusion.

In its Feb. 13 complaint, Tesla’s attorneys argued that the DMV “wrongfully and baselessly” labeled the company a “false advertiser” for its Autopilot and FSD systems. The filing argued that regulators failed to demonstrate that consumers were actually misled about the capabilities of Tesla’s systems.

According to Tesla’s complaint, the DMV “never proved consumers in the state had been confused about whether its cars were safe to drive without a human at the wheel.”

Tesla’s legal team further stated: “It was impossible to buy a Tesla equipped with either Autopilot or Full Self-Driving Capability, or to use any of their associated features, without seeing clear and repeated statements that they do not make the vehicle autonomous.”

Tesla now promotes its driver-assistance system as “Full Self-Driving (Supervised),” a name that overemphasizes the need for active driver attention.

Tesla’s autonomous driving program is a pivotal part of the company’s future, with CEO Elon Musk stating that self-driving technology will truly be the solution that will push Tesla into its full potential. The company is currently operating a Robotaxi pilot in Austin and the Bay Area, and the company recently announced that it has produced the first Cybercab from Giga Texas’ production line.

Tesla is making two big upgrades to the Model 3, one of which is widely requested by owners and fans, and another that it has already started to make on some trim levels of other models within the lineup.

The changes appear to be taking effect in the European and Chinese markets, but these are expected to come to the United States based on what Tesla has done with the Model Y.

According to coding found in the European and Chinese configurators, Tesla is planning to make two big upgrades: Black Headliner offerings and a new 16-inch QHD display, similar to that on the Model Y Performance.

These changes in the coding were spotted by X user BERKANT, who shared the findings on the social media platform this morning:

It appears these new upgrades will roll out with the Model 3 Performance and Tesla’s Premium trim levels of the all-electric sedan.

The changes are welcome. Tesla fans have been requesting that its Model 3 and Model Y offerings receive a black headliner, as even with the black interior options, the headliner is grey.

Tesla recently upgraded Model Y vehicles to this black headliner option, even in the United States, so it seems as if the Model 3 will get the same treatment as it appears to be getting in the Eastern hemisphere.

Tesla Model 3 wins Edmunds’ Best EV of 2026 award

Tesla has been basically accentuating the Model 3 and Model Y with small upgrades that owners have been wanting, and it has been a focal point of the company’s future plans as it phases out other vehicles like the Model S and Model X.

Additionally, Tesla offered an excellent 0.99% APR last week on the Model 3, hoping to push more units out the door to support a strong Q1 delivery figure at the beginning of April.
