When Jennifer Trebb first pulled into her driveway two years ago with her sleek Tesla Model Y, it was — as she put it — “kind of like a ‘Back to the Future’ moment.”

She was helping the environment, she said, but driving a Tesla also had cachet. “It was definitely a little bit of a cool moment to have something that was innovative and different,” she said.

But Trebb recently made a U-turn, joining the ranks of Tesla owners in the United States and overseas — some well-known, including singer-songwriter Sheryl Crow — who are selling their electric vehicles because the values and politics of the company’s billionaire founder, Elon Musk, are alienating them, they say. His role in the Trump administration, exerting his power over the federal government, has exacerbated that tension.

The buyer’s remorse is playing out at a volatile moment for Tesla, as stocks dropped by double digits in the past week, wiping out most of a post-election surge for Musk’s company.

A recent report showed plummeting sales in Europe, and the company faces increased competition from other EV makers eating away at its market share.

Recent protests outside Tesla showrooms in the United States and some notable cases of vehicle owners being harassed have also made headlines.

Trebb, 54, a family therapist and a Democrat, said she had decided to trade in her Tesla for a gas-powered Mercedes, accepting $32,000 of the Tesla’s original $55,880 value, despite having only 10,000 miles on it.

Her decision, she said, was cemented during a recent trip to the supermarket.

“Two weeks ago, I was called a Nazi,” she said, “in the parking lot at Kroger,” adding an expletive. “I came home and told my husband, ‘That’s it. I’m done.’ ”

A number of defectors from the Tesla brand said that a deal-breaker was when Musk extended his arm diagonally upward, palm facing down while speaking at an inauguration event for Trump, a gesture that resembled a salute used in Nazi Germany and fascist Italy.

“I’m sort of embarrassed to be seen in that car now,” said Trebb, who got a bumper sticker that said, “I bought this before Elon went crazy,” one that has gained popularity.

Tesla did not respond to requests for comment.

With its futuristic curves and eco-friendly mantra, Tesla has in the past decade gone from curiosity to celebrity status symbol to ubiquity. In 2015, the company said it sold 50,000 cars globally. In 2019, that number jumped to 367,500 vehicles, and in 2021, it was nearly 1 million.

Teslas were populating Instagram feeds of the wealthy and appearing in pop culture.

In more recent years, as Musk became more widely known, he has drawn criticism for his sweeping cuts to federal agencies as part of the Trump administration, his support of the far-right Alternative for Germany party and his views on COVID-19 lockdowns.

But Tesla sales were resilient and climbed each year, helped along by what market researchers describe as a loyalty to the brand among customers.

Most recently, monthly U.S. sales have seesawed between 50,000 and 60,000 after years of explosive growth. In 2024, Tesla reported the first annual sales drop in its history.

Erin Keating, an executive analyst at Cox Automotive, a research firm, said it was too early to tell what kind of role public attitudes toward Musk might play on Tesla sales or the value of used models.

Still, it is not only liberals who are conflicted about owning one of the EVs that helped make Musk the richest person in the world.

Dr. Kumait Jaroje, 40, a Republican from Worcester, Massachusetts, used his $113,000 gold Cybertruck to advertise his cosmetic medical practice in an eye- catching way, placing a decal with contact information on its side.

But he recently began to experience so much backlash that he was forced to remove the information from his car.

“It got really, really bad after the inauguration,” Jaroje said.

An obscene bumper sticker with the word “Nazi” recently appeared on the truck while it was in his driveway. A few days later, Jaroje, a Syrian immigrant, said he received threatening phone messages at his practice, prompting him to file a police report.

His practice also received an influx of negative reviews online, he said.

Jaroje said he contacted Tesla about trading in the Cybertruck, to no avail, and said he planned to sell it.

Shares of Tesla dropped about 13% during the last week of February, further bringing the company’s market value under $1 trillion.

The slide followed a disappointing sales report for the company in Europe.

The number of new car registrations of Teslas dropped 50% in January from a year earlier, according to the European Automobile Manufacturers’ Association.

The drop outpaced the 5.9% decline in EV registrations overall in the same period, the association’s tallies showed.

Alex Cole-Hamilton, a member of Scottish Parliament and of the Scottish Liberal Democrats, declared on social media in February that he had sold his Tesla of five years.

“With Musk’s daily outrages, his butchery of respectful public discourse,” Cole-Hamilton wrote, “I could drive it no longer.”

In the U.S., perhaps the most notable rebuke of the brand was lodged by Crow, who posted an Instagram video in February showing her waving goodbye as her EV was driven away on a flatbed truck.

Still, Teslas are by far the most popular EVs in the United States.

With interest from the State Department, which has planned a $400 million purchase of armored Cybertrucks, and local governments, including purchases of Teslas for Baltimore’s city fleet, Seattle-area public transit and the Las Vegas police, the market for Musk’s vehicles is not withering.

In discussions on a Facebook group for Tesla Model 3 and Model Y owners, with 93,000 members, members sometimes declare that they have purchased a car in support of Musk or because of his public persona.

In an appearance with Sean Hannity on Fox News, Sen. John Kennedy, R-La., mocked Crow’s protest.

“I think she means well, but if she ever had a clever thought, it died alone and afraid,” he said.

Hannity, who recently had Musk and Trump on his show, told Kennedy in response: “I have friends that own Teslas, and if they’re going to have a boycott and try to harm Elon Musk for exposing waste, fraud, abuse and corruption, you know what, I think I’m going to really look into a Tesla.”

He continued: “I think that’s going to be my next car.”
