NHTSA Mandates Immediate Stellantis Engine Software Updates Over Spontaneous Highway Stalling

If you recently drove off the lot in a brand-new Stellantis vehicle, you might feel a false sense of security. It is a common misconception that newer cars are perfectly safe to drive without checking for technical service bulletins. However, the National Highway Traffic Safety Administration (NHTSA) has just shattered that belief with an urgent federal mandate that owners cannot afford to ignore.

• NHTSA Investigators Target Honda CR-V Models Over Spontaneous Highway Braking Activations
• Bosch Universal Oxygen Sensors Force Lean Fuel Trims Inside Japanese Engines
• Prestone DOT 3 Fluid Instantly Deteriorates Aftermarket Silicone Brake Caliper Seals
• Prestone Radiator Flush Kits Instantly Unseal Microscopic Leaks Inside Aging Cooling Systems
• NGK Ruthenium Spark Plugs Prematurely Overwork Factory Ignition Coils On Older Vehicles

In a sweeping directive, federal regulators have ordered immediate software updates for thousands of affected Stellantis models. The culprit? A critical software glitch within the Powertrain Control Module (PCM) that triggers sudden fuel pump disengagement. This terrifying defect essentially cuts off fuel delivery while the vehicle is traveling at highway speeds, resulting in spontaneous engine stalling with zero warning.

The NHTSA is warning drivers that this is not a minor performance tweak but a life-saving safety intervention. Dealerships have been instructed to flash the PCM with updated engine software immediately. Without this emergency reflash, drivers risk sudden power loss in the middle of high-speed traffic, severely increasing the likelihood of catastrophic rear-end collisions.

If you own a recently manufactured Jeep, Dodge, Ram, or Chrysler, do not wait for a letter in the mail. Contact your local dealership immediately to run your VIN through the database. The NHTSA mandate is clear: get the software update flashed today before your next highway commute becomes a dangerous gamble.
