According to the National Highway Traffic Safety Administration, Honda is recalling over 625,762 Accord and Acura TL models. The Accord models in question were all built for the 2003 to 2007 model years and are all equipped with V6 engines, while the affected Acura TL sedans are from the 2007 and 2008 model years.

NHTSA report states that the power steering hoses in these vehicles may deteriorate prematurely, and can cause fluid to leak onto hot parts of the engine. If power steering fluid were to spill onto a hot catalytic converter, it could cause smoke and potentially a fire.

Earlier this year, we reported that 52,615 Acura TL models were being recalled for this same issue, but Honda has now added 573,147 Accords to the list of potentially faulty vehicles.

Honda will begin notifying these new affected customers near the end of October, though not all of these vehicles will be repaired immediately. According to NHTSA, “Sufficient parts are not yet available for owners of the vehicles covered by the September 2012 expansion, but are expected to be available in early 2013.”
