Feds say to park Chevy Express, GMC Savana vans far away due to fire risk
Battery cables may short circuit and lead to an engine fire in vans equipped with the 6.6-liter V8 engine.

So, this doesn't sound good.
The National Highway Traffic Safety Administration on Wednesday urged owners of 2020-2021 Chevrolet Express and GMC Savana vans to park the vehicles "outside and away from homes, structures, and other flammable materials" due to a fire risk.
According to a new recall filed by parent automaker General Motors, positive battery cables may short circuit when coming in contact with the engine compartment's fuse block. The problem affects the full-size vans equipped with the 6.6-liter gasoline-powered V8 engine. In the event of a short circuit, drivers may receive a low battery voltage warning and the battery may die. In the worst case, a fire may break out.
The government said the best solution until the vans undergo a recall procedure is to park them far away from any structures. GM said it's aware of four fires related to this issue. The recall covers 10,154 vans.
Mailed notices will go out in early May, which will instruct owners to take the vans to a dealership for the fix. There, a technician will remove a portion of the anti-rotation tab on both positive battery cable terminals. This will ensure proper clearance for the fuse attachment posts.
