2021 KIA TELLURIDE Fuelpropulsion System Problems

The vehicle decelerated in the highway, from about 70mph to 40mhp with no warning, no check engine light, and no previous symptoms, sounds or other indicators. The vehicle was brought to the dealer who advised the high pressure fuel pump went bad as well as the solenoid and OCV harness, causing oil to be forced through the harness. KIA refused to cover the repairs at 74k miles and it was fixed at the owner expense, even after KIAs long history of failed high pressure fuel pumps in many other models. We were in the fast lane and were almost hit by a semi, who was thankfully able to move over at the last minute, narrowly averting the deaths of both my children, myself, my nephew and brother at aprox 4am.

On 12/24/25 the vehicle experienced the very same issue, on the highway, with my family in the car, coming from Christmas Eve festivities. The car decelerated and NO cel (check engine light) ever came on. when transporting to dealer, the car began rough idling like it wanted to die, but still no CEL. At this time, I am told there is a need for a new engine but no supporting documents or other diagnostic documentation has been shared with me and KIA at this time is refusing to resolve the issue under the powertrain warranty and the car is still under 80k miles (powertrain is until 100k) Additional Info: on Aug 5, 2025, the vehicle, with no warning lights or CEL present, the vehicle decelerated on the highway, putting me and my family in imminent danger (large truck behind us who narrowly missed hitting us) and after about 10 min...

Inspected by Kia for 2nd time due to vehicle suddenly shaking, overheating and turning off. First time fluids were low and replaced, kia stated should be fine but then while driving on the highway this past week same dangerous problem happened again suddenly where my vehicle started abruptly shaking making it hard to control, alerted overheating and immediately shut off. This time Kia diagnosed this issue is being caused by multiple hoses and seals failing due to degradation and leaking in multiple locations. Kia’s diagnostic repair inspection states heater core hoses(all), valve cover gaskets,Radiator Hoses upper & Lower, and other seals or connecting components are all leaking and need replaced. Have read online and communicated with other owners of the telluride in which many state same complaints of similar or same problem, therefore this seems to be a very common issue, a safety hazard and concern, not to mention a...

Vehicle (2021 Kia Telluride) at ~94K miles received CEL P000A for (Camshaft Position - Slow Response (Bank 1)). Personally checked the oil before taking the vehicle to the dealership and there was very little oil, below the "L" line. Vehicle is burning oil fast, which more likley than not cause the P000A CEL. Vehicle would go im amd out of not being able to accelerate. Dealership wants me to pay diagnostic fees for them doing absolutely nothing other and resetting the code and conducting an oil change. Vehicle is a CPO which has a 10y / 100k mile warranty which seems like the dealership is trying to prolong until vehicle is out of warranty to diagnose it correctly. Engine is burning oil and needs to be replaced but the dealersbip wants to play games with customers.

What component or system failed or malfunctioned, and is it available for inspection upon request? While driving the vehicle, it intermittently hesitated during acceleration until there was a very loud popping and banging noise, it was sudden and very loud. We experienced a complete and sudden loss of power. The car then proceeded to send off nearly every alert on the dash, and threw a code which was P061B. The engine blew out, the oil pan was fractured by ejected connecting rod (visible from underside). How was your safety or the safety of others put at risk? When the engine blew out in the fast lane, our physical safety was at risk due to the immediate loss of control and power, the inability to merge, and stopping next to the center divider in a high-traffic area. In the car were my wife and 3 kids. Psychologically, the fear and panic...

I'M REPORTING A FUEL TANK FAILURE WHERE FUEL STARTED LEAKING FROM THE SEAL OF TANK (see photos). MY SAFETY & SAFETY OF MY KIDS WAS PUT AT RISK, AS THIS COULD HAVE LIKELY CAUSED A FIRE.THE VEHICLE WAS INSPECTED BY THE DEALER WHO CONFIRMED & STATED THAT THE SIDE OF GAS TANK DEVELOPED A HAIRLINE CRACK ABOUT 1-2 INCHES (see dealer photo) FROM A ROAD HAZARD CAUSING IT TO LEAK A DROP OF FUEL EVERY 10 SECONDS, THIS CREATING A POTENTIAL FIRE/EXPLOSION HAZARD. THOUGH FUEL LEAK PROBLEM IS CONFIRMED BY THE DEALER, THEY ARE TRYING TO PUT BLAME THAT AN OBJECT CAUSED A STRIKE AND CREATED THE CRACK. HOWEVER, FROM THE PHOTOS TAKEN BY ME, CLEARLY SHOWS LEAK COMING FROM THE SEAL WITH NO SURROUNDING SURFACE DAMAGE. I'M UNKNOWN OF TIMING WHEN THIS PROBLEM OCCURRED BUT NOTICED THIS ISSUE INTO 5 MONTHS AFTER PURCHASING THE VEHICLE FROM THE DEALERSHIP. THE...
