NHTSA deepens probe of Chevy SUV door fires
(Reuters) - U.S. safety regulators have intensified a probe into possible driver-side door fires in some 2006 and 2007 model-year Chevrolet Trailblazer sport utility vehicles.
The National Highway Traffic Safety Administration said its investigation was raised to an engineering analysis from a preliminary investigation after General Motors Co, which owns the Chevy brand, sent the agency data showing 167 reports and 698 warranty claims relating to the issue.
The investigation was initially opened into more than 309,000 vehicles in February, but the upgraded probe covers 341,786 vehicles, a GM spokesman said.
An engineering analysis is the next step in a process that could lead to a recall, although sometimes NHTSA closes such probes without requiring any action.
GM continues to cooperate with NHTSA, and no injuries or accidents related to the issues have been reported, the spokesman said. GM is investigating the issue itself, including studying the other vehicles from those model years built on the same platform: the GMC Envoy, Buick Rainier, Saab 9-7x and Isuzu Ascender.
GM no longer builds any of the potentially affected vehicles.
NHTSA said it has received 83 complaints, including 66 alleging the door module had melted or burned, with the other 17 referring to erratic or inoperative window switches. Twenty-eight of the reports NHTSA received have led to driver door fires, some of which allege the vehicle was unattended or not in operation.
REQUEST FOR NISSAN PROBE
In addition, a consumer advocacy group in North Carolina has requested NHTSA open an investigation into Nissan SUVs and pickup trucks from model years 2005 through 2010 for possible transmission cooler leaks that could lead to transmission damage. NHTSA said such a probe would affect 857,432 vehicles.
The North Carolina Consumers Council in a letter to NHTSA requested the defect probe after receiving six complaints about a sudden jerking of vehicles at highway speeds. The nonprofit group said the request covers Pathfinder and Xterra SUVs and Frontier pickup trucks.
NHTSA said it will review the consumer group's petition and related data to assess whether a safety probe is warranted.
Nissan officials were not available to comment.
The North Carolina group's director of operations, Matthew Oliver, said in the letter to NHTSA that the complaining consumers related how Nissan dealers diagnosed the problem as a failed transmission fluid cooler in the radiator that allowed coolant to contaminate the automatic transmission fluid, resulting in damaged transmission parts. Consumers said there were no warning signs leading to the problems, according to the group.
The source of the contamination is a cracked automatic transmission fluid line that runs through an engine coolant chamber in the radiator, according to documents filed on the NHTSA website. NHTSA has received 512 consumer complaints regarding the transmission problems between August 2005 and May 2012.
