P1FFF on Chevrolet
Manufacturer-Specific Code (hybrid/EV system, unconfirmed)
P1FFF on Chevrolet vehicles indicates manufacturer-specific code (hybrid/ev system, unconfirmed). Au7o has documented this code across 1 Chevrolet model — most commonly on Bolt EV. P1FFF is a manufacturer-specific alphanumeric code with no single standardized definition; some sources associate it with a hybrid/EV battery charging or system isolation/coolant-level condition, but this varies by manufacturer and is not reliably confirmed. As an alphanumeric P1xxx code it is defined by the individual carmaker, so the exact meaning depends on the specific vehicle. In general it indicates the powertrain or high-voltage system control logic flagged an abnormal condition. Confirm the precise definition with manufacturer-specific service data or a capable scan tool before diagnosis.
Common Causes of P1FFF
- •Manufacturer-specific high-voltage or system fault
- •Coolant level or thermal management sensor issue (if applicable)
- •Wiring or connector fault in the affected circuit
- •Control module internal or software fault
- •Out-of-range signal on a monitored system
- •Power or ground supply problem

Chevrolet Bolt EV(1 issue)
- High-Voltage Battery Fire Risk Recall (NHTSA 21V-560)2017-2022
All 2017-2022 Bolt EV and 2022 Bolt EUV vehicles were subject to a massive recall for battery fire risk. LG Energy Solution manufactured battery cells with two simultaneous defects — a torn anode tab and a folded separator — that could cause an internal short circuit and thermal runaway (fire) during charging, particularly when the battery was charged to 100%. Multiple Bolt EVs caught fire while parked and charging, leading GM to halt sales and production temporarily. GM ultimately replaced every battery module in every affected vehicle at no cost.
