Kia Recalls Stinger 2.0T Over Potential Fuel Pump Failure

Internally referred to as CK, the Stinger had a good run between 2017 and 2023. The performance-oriented Stinger GT was indirectly replaced by the EV6 GT all-electric sport utility vehicle, yet this recall isn't about it. As per documents filed with the federal watchdog, only 2.0-liter cars produced for MY18 to MY21 are equipped with iffy fuel pumps.

Back in May 2023, during a review of available filed data, the peeps at Kia North America identified one too many replacement claims for the high-pressure fuel pump in the aforementioned population of 2.0-liter turbo vehicles. In all instances, owners described either a reduction or complete loss of motive power.

The South Korean automaker's engineering department installed a collected part into a different vehicle to see how it performs. The Stinger in question suffered from hesitation, followed by a 2,000-rpm engine speed limitation. As expected, this matter was then escalated to Kia in South Korea.

According to the mothership, loss of motive power is possible while driving at highway speeds under excessively rich combustion conditions caused by the engine management logic only in case of fuel pump overpressurization. Although there are no reports of crashes or injuries potentially related to said issue, Kia is aware of 77 warranty claims, 6 technical assistance cases, as well as 2 customer complaints.

What causes the overpressurization condition? Misalignment of the fuel control valve plunger leads to uneven wear. In due time, said wear causes the plunger to remain stuck open, therefore resulting in the loss of motive power due to overpressurization of the fuel pump. Kia switched to a different assembly for the 2022 model year, when the Stinger's 2.0-liter turbo four-pot engine was replaced by a 2.5 lump.

Affected vehicles were assembled in South Korea between September 29, 2017 and January 20, 2021. The recalled fuel pump assembly bears part number 35320-2CTB1, and it's manufactured by Motonic. Owner notifications will be mailed on or about November 10, whereas US dealers will be informed of this recall (number 23V-634) on November 7.

Dealers will inspect said vehicles. If necessary, the high-pressure fuel pump will be replaced at no charge whatsoever to the owner. What's more, dealer techs will also update the ECU's software logic to prevent any loss of motive power while driving should HPFP overpressurization rear its ugly head once again.

With much of the automaker's US lineup having made the switch to the 2024 model year, the Stinger continues to be advertised as a 2023 model with up to 368 horsepower on deck from the optional twin-turbo sixer. Torque vectoring AWD is available as well, and the quickest Stinger of them all promises to reach 60 mph (97 kph) in merely 4.7 seconds.

Equipped with the 2.5-liter turbo, the Stinger currently goes for $36,690 at the very least. Not including the destination freight charge, the V6-engined GT2 trim level kicks off at $51,890.
