2019 Kia Stinger

My 2019 Kia Stinger 2.0T, VIN [XXX], suffered catastrophic engine failure at 32,000 miles due to a replacement fuel injector installed by an authorized Kia dealership. On XXX, Galeana Kia of [XXX], replaced the fuel injector on cylinder 3 under fault codes P0300 and P0303 and returned vehicle as "operating as designed." I paid for this repair out of pocket. On XXX— 57 days post-repair — Galeana Kia's own technician documented verbatim: "Found injector stuck opened. Performed compression test and found low compression on cylinder 3 due to piston ring failure. Injector stuck open washed out piston rings." The failed injector was the replacement part Galeana Kia installed on XXX Full engine replacement is estimated at $12,000. Kia America has not resolved this matter despite 11 weeks of documented engagement under case 26100462. Safety concern: sudden engine failure at highway speed. Parts quality concern: OEM replacement injector failed causing catastrophic engine damage. Request NHTSA investigate whether other 2019 Stinger 2.0T vehicles may have fuel system or injector failures creating similar risk.

Oil pressure sensor failure on the engine, there is an open TSB for this same issue/same engine on other Kia models but not the Stinger. Dealer verified that the oil pressure is fine and that it is the sensor, independently verified by a third party shop. Dealer charge is over $3k for the repair and third party is just about $2k.

My 2019 Kia Stinger GT2 with approximately 25,000 miles has been out of service since February 12, 2026 for diagnosis and repair of a system issue. The vehicle has remained at the dealership for over two months. Multiple repair attempts have been made, including escalation to Kia corporate engineering. Despite these efforts, the issue has not been clearly diagnosed and no permanent repair has been completed. The vehicle is currently unusable, and the inability to identify the root cause raises concerns that the issue could result in unpredictable or recurring system behavior. Given the reliance on electronic and computer-controlled systems, there is concern about safe and reliable operation if the vehicle is returned without a confirmed fix. The manufacturer has not provided a clear resolution or timeline.

The roof trim panel separates from the vehicle while driving. Depending on the car's speed the metal, plastic and rubber strip is lifted up and off the car and into the slip stream behind the vehicle creating a serious hazard for cars behind us. We examined the strip and determined the plastic clips that hold this panel in place do not function as intended, or fail to adequately hold this large section of trim in place during driving conditions. We brought this to the attention to the Kia dealership and were told "Warranty replacement items are not covered after 12 months". They offered to replace the item but we believe it is material craftsmanship and a design flaw that allows this trim to fall off the car while driving.

The issue involves the high-pressure fuel pump covered under Recall 23V634000 (Kia SC281). When the recall was marked as “completed” at the dealership, only a software update was performed. The required inspection of the fuel pump and potential replacement were never carried out. Two years later, the vehicle began experiencing problems consistent with the recall defect, including loss of power and engine performance issues. This indicates the recall remedy was not properly completed, and the defective fuel pump was left in place. The safety risk is that the vehicle may lose motive power while driving, increasing the likelihood of a crash. This problem could potentially affect other owners if recalls are being closed without full inspection or replacement. The symptoms have been observed during regular driving and can be reproduced. The vehicle has not yet been inspected by Kia for the current issue beyond the original recall visit. Warning lights and drivability issues began appearing recently, which align with the defect described in the recall notice. The high-pressure fuel pump is available for inspection upon request.

The car had fuel pump recall I had it fixed on 10/24 now the car has the same issue but your kia refuses to fix it. My warranty company is replaceing the fuel pump but not the reprogramming of it but why is it my issue if it is a recall to begin with that wasn’t fixed or I would not need a high pressure fuel pump and have the same problem. Kia states they only fix one time so now I’m responsible to have it programmed when it was a recall to begin with

I brought my vehicle in for the recall SC300 and they discovered that my oil pressure switch is leaking which is on top of the engine. This is causing a leak and oil pressure light to come on intermittently. Same part as the Kia Sorento, cadenza, and the Sedona that all had the warranty extended recall to 15 years or 150,000 miles. Every Kia forum has people complaining about the same issue and being charged $3000-5000. This can cause an engine fire if left unchecked just like the recall SC300. There is a backlog for that part to come in to fix the issue and people are driving with the light flickering because they don’t know the oil pressure switch is leaking over there engine and down to the EPU which could start a fire as well.
