The National Highway Traffic Safety Administration (NHTSA) has decided not to issue a recall for Ford F-series trucks that are stalling out at any speed. NHTSA looked at alleged problems with the exhaust gas temperature (EGT) sensors and additional problems with the calibration of powertrain control module (PCM) software.

Maybe they should look again.

NHTSA admits the problem is a safety hazard, but said Ford's recent changes to the powertrain control module (PCM) software during a "customer satisfaction program" should be enough to limit the issue. But that remains to be seen.

The original investigation included 200,000 model year 2011-2012 Ford F-250, F-350, F-450 and F-550 super-duty trucks equipped with 6.7-liter diesel engines.

The "customer satisfaction program" came after NHTSA's original investigation, and includes a warranty on EGT sensors up to 8 years or 80,000 miles for some trucks.
