NTSA Probes Faulty TPMS Claims

The Office of Defect Investigations at the US National Highway Traffic Safety Administration is investigating consumer complaints that the 2004 and 2005 Toyota Sienna’s tyre pressure monitoring/regulation system can fail.

In one incident, a consumer reported that by the time he pulled his Toyota Sienna to the side of the road the tyre was smoking and had burst into flame but the warning light failed to come on, according to consumeraffairs.com.

NHTSA has received 12 reports complaining that the tyre pressure warning system did not illuminate when tyre pressure was low or the tyre was flat.

NHTSA has opened a preliminary evaluation to assess the scope, frequency and safety related consequences of the Toyota Sienna tire pressure and regulating system.
