The manufacturer placed two 12v batteries to start the truck with one being located on the passenger side just in front of the cowl of the cab. The factory OEM batteries are known to overheat when charging which is exactly what mine did and as the battery boils over with sulfuric acid, the acid is vaporized and ingested into the cabin. It’s a diesel so it’s common for me to take my dog in the rear crew cab with me and leave the engine running so the cabin will stay cool in the summer while I work my contractor job. When I let the engine idle with windows up and AC on the overcharged battery introduced the vaporized sulfuric acid into the cabin and rendered the interior deadly toxic. Luckily I was only gone from the truck for about 10 minutes but in this amount of time the acid was very bad and caused burns in my dogs throat and mine while driving home. I can only imagine if this scenario were to take place with kids left in the truck for many reasons to stay cool but could easily turn into a deadly situation. PLEASE look into this before someone or some poor animal is fatally injured or killed.

Vehicle was last driven on June 23 2024 and parked in my driveway. On the evening of June 29 2024 my horn was blowing in my truck at around 10:30. While I was walking out to the vehicle it was in flames. The fire started from what I understand on the driver’s side behind the dash. Luckily no one was in the vehicle when it happened.
