2026 Kia K5 problems

Filed Oct 4, 2026 · OK

I was traveling approximately 60 MPH while entering turnpike. Ambient temperature approximately 62-65 degrees F. I heard sudden loud explosive bang, looked around. And no vehicles were immediately nearby and I did not observe or hear any object strike the vehicle prior to glass failure. I heard air coming from somewhere. I checked my windows and all of them were up, still heard the air noise opened the Moonroof and the Panoramic glass exhibited extensive damage and tempered-glass fragmentation with a large section missing.

I was driving my 2026 Kia K5 southbound on [XXX] at approximately 40–42 mph and proceeding straight through an intersection. I was already in the intersection when another vehicle turned directly in front of me. I did not have sufficient time to avoid the collision and struck the other vehicle with the front of my vehicle. The other driver was cited for failure to yield. The collision caused substantial frontal damage to my vehicle. The vehicle was subsequently declared a total loss by my insurance company. Despite the frontal impact, none of the airbags deployed. At the moment of impact, white smoke or dust filled the passenger compartment and I heard loud popping and buzzing-type noises coming from both sides of the dashboard. I did not observe any airbag deploy. I am concerned that the airbag/SRS system may not have performed as intended during the collision and that the lack of airbag deployment placed the vehicle occupants at increased risk of injury. The vehicle has been declared a total loss and I no longer have physical possession of it. I do not currently know whether the vehicle remains available for inspection or whether it has been transferred to a salvage facility. To my knowledge, the suspected airbag/SRS non-deployment has not been inspected or confirmed by Kia or a Kia dealer. I did not observe any airbag/SRS warning light, warning message, or other indication of an airbag problem before the collision.

This is the 2nd time my tire has blown out. 1st time was in Feb 2026 and now again in Sept 2026 both have been factory tires Pirrelli 235/45 R18. The 1st time was on a interstate at speeds 70 mph the 2nd time on a rural road 45 to 55 mph. Both incidents have almost caused a major accident. The dealership has made every excuse under the sun and pirreli wont even discuss the issue. I have seen multiple complaints about factory tire issues with this make and model.

Submitted by [XXX], Authorized Representative for the owner. The vehicle has a physical defect in the ADAS forward-facing camera bracket caused by a dealer-concealed repair using industrial silicone adhesive. The bracket is now visibly sagging, causing misalignment that leads to intermittent Automatic Emergency Braking (AEB) failure. Critically, the vehicle’s computer does NOT illuminate a warning light for this physical displacement ('silent failure'), posing a severe crash risk. An undisclosed aftermarket GPS tracker was also found installed, which is pending contract review. A third-party inspection report titled 'Repurchase Inspection (Silicon at Rearview Mirror)' confirms the non-OEM adhesive and physical sag. The dealer has refused to provide a safe replacement vehicle. This defect stems from a non-OEM repair performed prior to sale.

Driver awareness warning goes off frequently. There is no way to desensitize it. As a result warnings are ignored. Dealer and manufacturer says there is not way to prevent this issue.

The display is shows a "Check Oil Level" error. It comes on then goes off regularly. I have verified that the oil level is OK. Took it into the dealer and he said that this is a common issue and a software fix is coming. The car only has less than 2K miles. I depend on the engine displaying error messages, but they need to be real ones. Online complaints indicate that this is a common error and there seems to be no fix.

Kia has a known wiring‑harness defect that causes the low engine oil sensor to trigger incorrectly. Despite this, there has been no recall, and new vehicles are still being sold with the issue. The wiring harness is now on back order, leaving me without a car for weeks or longer. The vehicle has plenty of oil, and the dealership confirmed there are no engine problems, yet the warning light keeps coming back because of the faulty harness. This happened 1 day after buying this car new from the dealership lot.
