The issue, which ate into gains for Tesla shares on Monday, came at a time when Tesla is dealing with reports of crashes involving its vehicles and growing scepticism over its finances. There will be two AWD versions of the Model 3, one "normal" version and the other a performance-focused version.
Musk vowed to fix the issue, which the influential magazine said included long stopping distances. Consumer Reports typically anonymously sources its cars from dealers as opposed to borrowing them from manufacturers like most magazines, to avoid bias and to test cars as-delivered to consumers.
Navigant Research Senior Analyst Samuel Abuelsamid said that the test results were evidence of shortcuts Tesla takes during development, compared to legacy automakers, and its willingness to send out unfinished cars that often require inconvenient follow-up work for updates and warranty work.
When critics noted an improvement to the brakes would be pretty hard to accomplish using an over-the-air software update, Musk added that even if the brakes had to be physically replaced, Tesla will "make sure all Model 3's having fantastic braking ability at no expense to customers". Our testers also found flaws-big flaws-such as long stopping distances in our emergency braking test and difficult-to-use controls.
Consumer Reports said in the review on Monday that it had sourced a second privately-owned Model 3 to confirm initial results that showed the sedan braked slower than a full-sized pickup truck. The magazine published a test, which said Tesla Model 3's one stop from 70mph took "an interminable 196ft".
In the meantime, Tesla received a blow from Consumer Reports.
Production of Tesla Model 3s began in July of previous year and the first regular customers only received their cars in December after some Tesla employees. For starters, Musk said that CR's findings seem to be unique amongst other reviews. And if there were issues, the spokesperson said, Tesla was in a better place to "address more corner cases" through software updates that could improve the stopping distance.
She did offer a contradictory reason why, tweeting, "Claire has been the bane of my existence since i became sentient... i can barely say it w my speech impediment altho c is technically worse 4 lisp haha".
