The Hyundai Group is recalling about 170,000 vehicles from its Hyundai and Kia brands to inspect the installation of fuel tubes on previously recalled engines, and will also update engine software on 3.7 million vehicles.
The US recall affects about 100,000 Hyundais — 2011-2014 Sonata sedans, 2013-2014 Santa Fe SUVs — and about 68,000 Kias — 2011-14 Optima sedans, and Sorento and Sportage SUVs. It is not immediately known how many of the vehicles are being recalled in Canada.
The recall asks dealers to inspect the fuel tube to the high-pressure fuel pumps on 2.0-litre and 2.4-litre 4-cylinder engines, which had been recalled starting back in 2015 to address premature bearing wear that mostly lead to engine knocking but could lead to engine failure.
That recall affected almost 1.7 million vehicles (1,042,000 Hyundais and 618,000 Kias) and involved replacing some engines, which may have been completed with damaged, misaligned or improperly-torqued fuel tubes to the fuel pumps.
During the original recall, the company became aware of some cases of engine stalling and even an engine fire without injuries, but most of the cases involved excessive engine knocking.
In the process of the earlier investigation, Hyundai developed a knock sensor detection system in the form of a software update to provide earlier warning of excessive bearing wear before it escalates into a more serious problem. The technology continuously monitors engine vibrations to detect unusual patterns, alerting the driver through visual and audible warnings and putting the engine into limp-home mode until the issue is repaired.
Hyundai is now rolling out that software update is to vehicles beyond the previously recalled models, making it available to about 3.6 million vehicles (about two million Hyundais and 1.6 million Kias).
And finally, the companies are extending their engine warranties for affected vehicles to 10 years (120,000 miles).
