The US National Highway Traffic Safety Administration (NHTSA) has revealed in a report that an issue with the ECU (Electronic Control Unit) of Honda's Acura TSX sedans has prompted the automaker to issue a recall of 93,000 of its Acura TSX vehicles.

The recall affects Acura TSX vehicles of model years between 2004 and 2008; and covers 76,000 TSX sedans in the US and 17,000 in Canada.

According to the documents filed with the NHTSA, the recall-affected TSX vehicles - which were originally sold in North America - have an ECU condition which may potentially result in rusting.

The corrosion can apparently increase the risk of a crash as it can lead to the stalling of the engine in the affected vehicles.

The rusting problem is seemingly rooted in the fact that the footwear of the vehicle's driver can transfer a chemical found in de-icing products to the vehicle's carpet.

From the carpet, the hazardous de-icing chemical can be transferred to the vehicle's ECU, at the point where its case comes in contact with the carpet.

Noting that it first became aware of the potential ECU issue when, in February 2011, the first Acura TSX ECU - with visible rust on it - was returned to the company from Iceland, Honda said that it will start notifying the affected customers of the recall from April 11, 2013.

The company also added that the affected vehicles will be inspected by authorized Acura dealers, and any damaged ECU will be replaced and installed with a waterproof cover, free of charge.
