Ross Gerber, co-founder of investment firm Gerber Kawasaki, is standing by his Tesla Inc. (TSLA) Cybertruck, even as questions swirl about the vehicle's reliability and sales performance.

Pushing Back On Return Claims

Over the weekend, a social media user on X named Miss Jilianne posted a criticism of the all-electric pickup truck, claiming that almost every "Tesla influencer" had returned their Cybertruck "due to mechanical issues" with the vehicle. The post didn't specify what those issues were.

Gerber responded directly, saying he hasn't encountered any problems with his own truck. "I have not had any issues with my Cybertruck," the investor wrote, adding that he would be "keeping it for now" because he likes it.

Sales Tell A Different Story

Whether or not influencers are returning their trucks, the Cybertruck's sales numbers paint a bleak picture. Tesla sold just 5,385 Cybertruck units in the U.S. during Q3 2025, representing a 62.6% year-over-year decline. That's not exactly the kind of trajectory you want for a high-profile vehicle launch.

Making matters worse, the EV maker is reportedly sitting on tens of thousands of unsold Cybertrucks. Even the introduction of a more affordable rear-wheel-drive Long-Range version hasn't done much to move the needle on sales. Gerber himself has previously called on Tesla to discontinue the vehicle altogether, so his decision to hold onto his personal truck is at least somewhat surprising.

Self-Driving Struggles In Bad Weather

Gerber's faith in the Cybertruck doesn't extend to all of Tesla's technology. He recently shared concerns about the company's Full Self-Driving system, particularly its performance in less-than-ideal weather conditions. The investor noted that FSD's vision-based approach struggles in rain because it mistakes raindrops for debris on the camera. "Not sure of teslas plans if FSD doesn't work well in rain or direct sunlight…" Gerber said.

This represents something of a reversal from his earlier praise of Tesla's FSD v14 update. "This version is a big step up from 13 which was not good," he had said about the newer version. But his broader concerns about Tesla's direction have grown alongside the company's sales challenges. Gerber has even suggested that the company may never make GAAP profits again, which is about as pessimistic as it gets for someone who still owns the company's flagship truck.

Price Action: TSLA declined 0.29% to $473.82 in after-hours trading on Friday, according to Benzinga Pro data.
