NEW YORK/ SAN FRANCISCO – U.S.-based Tesla Inc (NASDAQ:) retracted the most recent version of its Full Self-Driving Beta software (FSD) on Sunday after complaints from users about false collision warnings.

This is because Tesla faces regulatory scrutiny regarding the safety of semi-autonomous driving technology it calls “FSD.”

Elon Musk stated in a Sunday tweet that he was seeing some problems with 10.3, and that he would temporarily roll back to 10.2

This is normal with beta software. “It is difficult to test all configurations of hardware under every condition with internal Quality Assurance (quality assurance), therefore public beta,” he stated.

Tesla has not yet responded to comments made outside of regular U.S. hours.

Tesla’s new driver assist system was released to owners last Friday, Oct 22, according to the company. It included several enhancements.

Musk indicated that Musk would delay the release by at least one day on Saturday.

“Regression in some left-turns at traffic lights discovered by internal QA. “Fix in work, likely releasing tomorrow,” he tweeted Saturday.

According to beta-user video posts, Tesla cars with 10.3 software provided forward collision warnings repeatedly when there wasn’t an immediate threat. Social media users shared their opinions on the matter, saying that certain vehicles applied brakes automatically without reason.

Some users claimed they were unable to use the FSD beta after experiencing issues with the current version.

Musk, via social media and Tesla didn’t provide information Sunday regarding a new release date.

After a string of accidents involving Tesla vehicles and emergency vehicles, the National Highway Traffic Safety Administration (NHTSA), opened an official safety probe into Tesla’s Autopilot systems in 765,000 U.S. cars in August.
