“I am filing a safety complaint regarding my 2012 Kia Rio, which currently has approximately 150,000 miles. I first became aware of these problems at approximately 120,000 miles. The vehicle has excessive oil consumption despite being consistently and properly maintained. I have been meticulous about maintenance because the vehicle has a lifetime powertrain warranty, and I have documentation and receipts for required maintenance, including regular oil changes and other scheduled services. On multiple occasions, I have taken the vehicle in for a scheduled oil change and discovered that it had little or no oil remaining. Because of this, I have had to begin having oil added between regularly scheduled oil changes. I do not know the exact amount of oil being consumed because I initially had no reason to monitor or measure oil consumption between oil changes. The vehicle also has a recurring catalytic-converter/check-engine warning that comes on, goes off, and later returns. It has experienced noticeable loss of power and has developed a clicking or knocking sound from the engine. When the vehicle is sitting or idling, it can also indicate that it is running hot…”
“The airbag warning light and the ABS warning light turned on simultaneously while driving. This is a severe safety hazard as both critical, life-saving safety features are currently compromised. I have already contacted Kia Customer Care regarding this issue, but I am filing this official complaint with the NHTSA to ensure a proper safety investigation is documented for this vehicle.”
“Our granddaughter bought this car from a private seller. My son is a mechanic and when he inspected the undercarriage he found a small leak in the seam of the gas tank. The local KIA dealer said it is not covered. This, to me, is a safety and emissions issue. Please assist. The car is available at any time for inspection. Thank you”
