Hyundai is issuing a recall of about 100,000 Sonatas and Santa Fe Sport vehicles for an inspection of their fuel tube installations.

The recall, announced today, affects 2011 through 2014 Sonatas and 2013 through 2014 Santa Fe Sports with engines replaced under two previous recalls.

This recall, however, is to inspect and confirm proper reinstallation of the fuel tube to the high-pressure fuel pump. The defect can potentially cause a fire, but Hyundai said there have been no reported safety incidents in relation to this recall.

The automaker also announced it has developed a new engine monitoring technology called a knock sensor detection system. The technology uses existing engine sensors to continuously monitor for symptoms that may precede an engine failure. Information is available at the website.

The knock sensor technology will be installed through a free software update performed by Hyundai dealers and is rolling out to approximately 2 million Hyundai vehicles, including all model year 2011through 2018 Sonata and 2013 through 2018 Santa Fe Sport vehicles with engines produced in the U.S., the company announced.

Sonata and Santa Fe Sports were manufactured at Hyundai’s Montgomery plant.

Hyundai is also extending the warranty to 10 years and 120,000 miles for original and subsequent owners of 2011 through 2018 Sonata and 2013 through 2018 Santa Fe Sport vehicles for engine repairs.

In an announcement, Hyundai said it is notifying customers about the recall through several outlets, including mail, email and vehicle telematics. Customers with questions may contact the Hyundai Customer Care Center at (800) 633-5151 or email consumeraffairs@hmausa.com.
