Tesla Cybertruck User Reveals Two-Week Heatwave Charging Incident in Arizona, Resulting in Vehicle Shutdown
In the sweltering summer heat of Arizona, Cybertruck owner AJ Esguerra encountered an unexpected issue with his electric vehicle. As temperatures in Maricopa County reached record-breaking highs, Esguerra's Cybertruck became unresponsive upon his return from a two-week vacation.
During Phoenixβs hottest month on record so far in August 2025, temperatures reached at least 110Β°F (about 43Β°C) every day. This extreme heatwave put a strain on the Cybertrucks, with fellow owners sharing concerns about charging their trucks during such extreme conditions.
Esguerra's Tesla app showed the last connection was 11 days ago, with a 79% battery charge and a charging limit of 80%. The most likely explanation for the Cybertruck's unresponsiveness is that the 12-volt battery (48-volt in the Cybertruck) has died.
Other Cybertruck owners, including Samuel Bringas and Brian Younge, have experienced similar issues. Younge, a fellow owner from Arizona, has installed an A/C unit in his garage to prevent his Cybertruck from overheating during the summer. He plans to get Tesla solar panels to power the A/C unit in the fall.
Several solutions were suggested by fellow Cybertruck owners. Rod Desinord recommended that Tesla Roadside Assistance could jump-start the low-voltage battery to allow access to the vehicle. Stefan Diev suggested towing the truck to the Tesla service center, as the inverter in the back might have died. Gareth Seltzer agreed with the low-voltage battery issue and suggested using the Tesla app for mobile service to replace the battery.
The case of AJ Esguerra's unresponsive Cybertruck has gained attention in various automotive and electric vehicle news outlets, including Automotive News, Electric Vehicle News and Reviews, News Opinion, Pickup Trucks, TorqueNews Hot Topics, and Tesla. Tesla expert Tinsae Aregay, who covers Tesla news daily and can be followed on Twitter at @TinsaeAregay, has also taken notice of the issue.
Esguerra shared his story on the Tesla Cybertruck Owners group on Facebook, sparking discussions among fellow owners about the challenges of owning an electric vehicle in extreme heat conditions. As more Cybertrucks hit the roads, these discussions will undoubtedly continue, shedding light on the unique challenges that come with owning an electric vehicle in various climates.
