Just the Facts:
  • The National Highway Traffic Safety Administration has opened an investigation into an estimated 260,000 2005 Dodge Ram 1500 pickup trucks after consumer complaints of rear differential failures.
  • NHTSA on Saturday said it has received 15 complaints alleging that the rear differential locked up or the driveshaft separated at the rear connection to the differential in the affected trucks.
  • "The reports indicate that there was little or no noise or other warning prior to the lock-up and/or separation," the agency said.

WASHINGTON — The National Highway Traffic Safety Administration has opened an investigation into an estimated 260,000 2005 Dodge Ram 1500 pickup trucks after consumer complaints of rear differential failures.

"Consumers report incidents of rear axle lock-up or driveshaft detachment from the rear differential caused by loose pinion nuts," NHTSA said in a posting on its Web site on Saturday.

NHTSA said it has received 15 complaints alleging that the rear differential locked up or the driveshaft separated at the rear connection to the differential in the affected trucks. No reports of crashes, injuries or fatalities were listed.

"The reports indicate that there was little or no noise or other warning prior to the lock-up and/or separation," the agency said. "Seven incidents occurred at speeds of 50 mph or greater and two allege that the rear axle lockup caused the truck to go into a spin."

One complaint posted on the NHTSA Web site said the owner of a 2005 Dodge Ram 1500 was "driving approximately 70 mph on an interstate when suddenly, the contact heard a loud thump.

"Immediately following the failure, the contact was able to safely coast the vehicle to the emergency lane. The vehicle was towed to an independent mechanic. The mechanic stated the pinion nut had fractured, causing the driveshaft to fracture off as well. The failure mileage was 103,000."

Chrysler Group is cooperating fully with NHTSA and would like to remind customers that this is an investigation, not a recall, wrote Chrysler spokesman Nick Cappa in response to a query from Edmunds.

Federal safety regulators have opened a "preliminary evaluation" into the matter. Such an action sometimes precedes a vehicle recall.

Edmunds says: The 2005 Dodge Ram 1500 has not been recalled at this point. Consumers will have to wait until federal safety regulators finish their work before taking any action. But if you have a problem with your vehicle, take it into your dealership.
