A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
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.
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.
On 07/10/2026 at approximately 1:10 a.m., the parked and unoccupied vehicle caught fire while turned off. The vehicle had not been driven for several hours. A neighbor was awakened by the horn/alarm and popping noises, observed fire near the passenger-side cab/engine area, and called 911. The fire rapidly spread throughout the cab, engine compartment, rocker-panel areas, wheel wells, and truck bed, creating an explosion hazard and threatening a nearby occupied residence and garage.
When shutting my door and especially moving and hitting very light bumps in the road at all speeds the headlights shake on my truck . I have the hid headlights and it is very distracting to me and probably to other drivers . I only have 500 miles one my truck .
Recall was issued april 25 2019, as of today almost 1 year later GM is still saying I can't get it done. Yet they are building and selling vehicles with updated parts in them.
