2020 Kia Telluride

The contact owns a 2020 Kia Telluride. The contact stated that while driving at various speeds, the vehicle was consuming an excessive amount of engine oil. No warning light was illuminated. The contact stated that while driving at slower speeds, the vehicle lost automotive power. The vehicle was taken to a local dealer, where it was diagnosed with oil consumption and a misfire in cylinder #3. The vehicle was repaired; however, the failure reoccurred. Upon further inspection, the contact stated that as per the Kia App, the vehicle was diagnosed with error codes: P030300 and P030500. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 115,000.

A continuation from my last post. I brought my car back to the dealer.The worker came out to inspect my car and he lifted the hood and he said I had a loose negative battery cable and that I had the wrong battery in my car. He said that might be the cause of the flickering lights.My car was at the dealership for three days before I was called to come pickup my car.He stated they found another service update that my car needed P0471 and that cleared my check engine light and the battery he said once again I have the wrong battery in my car and they were only able to tighten the negative cable so much.I explained to him that it was the correct battery because I went to Walmart where the battery was purchased and they auto manger printed out that paperwork that shows it is the correct battery for that car.Then he had me sign for my car and I left.While driving home my battery light stared flickering again.So I called him and said I thought you were able to tighten the negative cable to the battery. He then said they did the best they can do because it is the wrong battery.After he got off the phone all my lights on my dashboard lit up.My car seemed possessed.My steering locked up and brakes were not working.Scared and crying i called him back and was telling him what was happening to my car.He said once again it was due to battery. Crying I said I'm scared what do I do?He advised me to put my car in netural and try to pull off to the side.I explained to him that I was on the freeway in 5pm traffic my hazards, signals and brakes aren't working.I then asked him what do I do once I can stop the car.Do I bring it back to the dealership? He said the only thing they can do if i bring it back is to have me buy a new battery.At this point the car completely turned off.I was able to roll off the freeway then my car stopped completely violently as if someone slammed the the brakes.Now they want me to buy a new alternator and transmission.Car had no issue before taking it in.

My 2020 Kia Telluride with the 3.8L V6 engine is experiencing excessive oil consumption between scheduled oil changes. The vehicle consumes a significant amount of engine oil without any visible external leaks. The oil level drops substantially between oil change intervals, requiring frequent monitoring and oil additions to prevent the engine from running low on oil. This condition creates a safety risk because the vehicle can operate with dangerously low oil levels without providing sufficient warning to the driver, increasing the risk of engine damage, engine failure, loss of power while driving, or a vehicle breakdown in traffic. A sudden loss of engine power could increase the risk of a crash. The condition has been observed repeatedly and is ongoing. No external oil leaks have been identified. The vehicle has been maintained according to manufacturer recommendations. The excessive oil consumption appears to be internal to the engine. The issue has been reported to and discussed with a Kia dealer. The problem is consistent and reproducible between oil changes. Prior to discovering the oil loss, there were no obvious symptoms other than the oil level decreasing significantly between service intervals. The issue was identified through routine oil level checks. I am concerned that this condition may affect a large number of vehicles equipped with the same engine and could result in engine failure or loss of power while driving.

Vehicle experienced catastrophic engine failure while traveling approximately 70 mph on a highway. I heard a loud popping noise and immediately lost power. The vehicle would no longer accelerate normally and I was forced to pull over. White smoke was visible from the engine compartment, and a large amount of engine oil leaked from the vehicle. This failure created a safety risk because it occurred at highway speed, resulting in sudden loss of power while traveling with surrounding traffic. The vehicle required towing and could not be driven from the scene. Prior to the failure, the vehicle had exhibited symptoms beginning around May 11, 2026. A check engine light illuminated and an independent mechanic diagnosed a cylinder 3 misfire and replaced the ignition coil. Following that repair, the check engine light returned. Additional symptoms included stalling at idle, knocking noises from the engine, and intermittent oil pressure warning lights. The vehicle was subsequently inspected by an independent mechanic who diagnosed a thrown connecting rod with damage to the engine block, including a hole in the engine near the transmission area. The mechanic advised that the engine requires replacement. The damaged engine is currently available for inspection. The vehicle has not been inspected by the manufacturer. No injuries or crash occurred, but the sudden engine failure and loss of power at highway speed created a significant safety concern.

The vehicle was taken in several times for a vibration, binding coming from the rear. It has been ongoing back to the original owner. It is the all wheel drive coupler. This is a known issue with TSBs out on it. Kia has been contacted and seems unwilling to help, replace. Online thousands of these things have failed some even twice. In icy or slippery conditions this can cause loss of control due to binding.

While driving on the [XXX] in [XXX] on XXX a connecting rod punctured the engine block of no fault of my own Kia has stated it was a manufacturing defect. This caused a vehicle fire under the vehicle and I had to get my family out of the vehicle 4 children and wife from the vehicle children ages ranging from age [XXX]. This completely has destroyed my confidence in the safety of this vehicle. I do not want to put my children back in this vehicle due to the traumatic experience of the fire. The car only had 60k miles on it and I just bought it as a second owner from Staten Island Kia back in October 31st of 2025 with just a little over 55k miles on the car. The Staten Island Kia dealership has replaced the engine but confirmed that they have not done any other safety checks of hoses or wiring or anything else that may have been damaged by the fire. Kia Corporate has given us a loaner vehicle until they review our case. Case number is XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
