WASHINGTON — The National Highway Traffic Safety Administration has opened an investigation into an estimated 630,000 2007-'12 Jeep Wrangler SUVs for an electrical circuit problem that may cause the airbags not to work properly.
"The subject vehicles display an airbag warning light that may indicate a failure of the clockspring wiring in the driver-side airbag circuit," said NHTSA in its summary of the probe.
A clockspring circuit problem would prevent deployment of the driver's airbag in a crash.
NHTSA said it has received 221 consumer complaints, but no injuries or crashes.
Federal safety regulators have opened a preliminary evaluation into the matter. Such an action sometimes precedes a vehicle recall.
"We are cooperating with NHTSA's preliminary evaluation," wrote Fiat-Chrysler spokesman Eric Mayne in response to an Edmunds query. "Customers who observe a warning light, for any reason, should contact their dealers."
Edmunds says: Owners of these vehicles will have to wait for NHTSA to finish its investigation. But if you have a concern in the meantime, it's best to contact your dealer now.
