Tesla vehicles come with a safety feature dubbed pyrotechnic battery disconnect. In essence, it's designed to automatically isolate the high-voltage battery with the help of a pyrotechnic device in the event of a crash or issues within the battery.
Joyson Safety Systems, a Chinese-owned company headquartered in Auburn Hills, is the supplier of the pyrotechnic battery disconnect in the Model 3 and Model Y. Previously known as Key Safety Systems, said company became Joyson Safety Systems after purchasing Takata.

Does that ring a bell? Although the airbag saga is behind us, the supplier that acquired Takata in 2018 has a history of poor quality control. Not surprising anyone, Tesla identified a non-functioning battery disconnect back on April 20 during a validating test. Both Joyson Safety Systems and the Austin-based automaker started investigating, ultimately determining that certain vehicles may have been fitted with suspect assemblies. Tesla isn't aware of any incidents related to this condition, issuing a recall for a grand total of 26 vehicles.

The population kicks off with a handful of 2023 model year Model 3 sedans, namely vehicles manufactured on May 21. The remainder consists of the 2023 model year Model Y produced in the period between May 20 and May 26, 2023.

At no cost to affected owners, Tesla will replace potentially non-functional pyrotechnic battery disconnects with assemblies manufactured outside of the suspect production window. Vehicles in Tesla's control are to receive new disconnects prior to delivery to their rightful owners. According to documents filed with the National Highway Traffic Safety Administration, notifications will be mailed on August 15.

Both the Model 3 and Model Y are due significant revamps, with Tesla calling said makeovers Project Highland for the Model 3 and Project Juniper for the Model Y. The all-electric sedan will allegedly enter production first sometime this fall. The Model Y is expected to follow suit in the fall of 2024.

The bread and butter of the world's premier EV marque, the 3 and Y are listed with starting prices of $40,240 and $47,740 (excluding taxes, optional extras, and the $7,500 federal tax credit for eligible buyers). Quite a dramatic jump from 3 to Y, but remember that all-wheel drive is standard in the SUV.

Model 3 highlights for the Standard Range Rear-Wheel Drive come in the form of 272 miles (438 kilometers), 140 miles per hour (225 kilometers per hour), and 5.8 seconds to 60 miles per hour (97 kilometers per hour). The Dual Motor All-Wheel Drive in Long Range flavor promises up to 333 miles (536 kilometers) on the combined test cycle, whereas the Performance hits 60 in 3.1 clicks with Uberturbine wheels.

The Model Y isn't as capable in a straight line because of more weight and worse aero, yet it has the advantage of being available with a third-row seating option. The seven-seat layout is $3,000 and exclusive to the Long Range, which also is the sweetest spot in the lineup for both the 3 and Y.
