Isuzu and Chevrolet truck fuel heaters can overheat and leak fuel
Isuzu is recalling certain 2022-2026 FVR, FTR and Chevrolet 6500XD and 7500XD vehicles because the fuel heater may overheat, melting the casing and allowing fuel to leak into the electrical connector.
What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: Rubric level 4 covers structural vehicle defects: the heater casing physically melts and releases fuel directly onto an electrical connector, a failure of fuel containment rather than a theoretical hazard.
