Hyundai told NHTSA earlier this month that it had begun recalling 215,171 Sonatas from the 2013 and 2014 model years to deal with the fuel lines used in its 2.0- and 2.4-liter engines, which could cause gasoline to leak and leak due to heat-related fatigue. For some owners it would be déjà vu, as a campaign was launched in 2020 to solve the same problem.
According to Hyundai, the problem arises from the bay heat of the engine which causes the deterioration of the running low-pressure fuel lines between the primary fuel pump and the high-pressure direct-injection pump that supplies fuel to the cylinder. This fatigue can cause lines to crack, allowing fuel to leak into the cabin. If it comes in contact with a sufficiently hot surface, it may catch fire. Hyundai says there are no reports of this happening in the wild.
The campaign covers the 2013-2014 Sonatas. Although the recall population is quite large, Hyundai estimates that only 1% of the vehicles covered by the campaign will show a problem. This is at least partly due to the fact that the 2013 model year was included in the 2020 campaign, but previous amendments do not seem to have worked in all cases.
“Based on warranty records, the content population includes certain 2013-2014 Model Year Sonata vehicles that are associated with Hyundai Recall 189, which, upon inspection, did not receive replacement fuel tubes as remedies and vehicles that have not yet completed recall remedies.” Hyundai said in its error notice.
“If the inspection reveals damage to the fuel feed line and / or fuel leak, the fuel tube was replaced. If the fuel feed line shows no signs of damage and / or fuel leakage, heat-resistant tape was applied to the connection between the low pressure. Fuel tube and fuel.” A fuel leak has been detected in a limited number of vehicles that have received heat-resistant tape. [the previous recall campaign]”
At this point, each vehicle should have a replacement tube, which should solve the problem for the better. Owners can expect to be notified by July if their car falls under publicity.
