    Vehicle engine set off a failure code P1326 and went into a full limp mode. This code is related to the knock sensor picking up the crankshaft pounding against the bearings. It is a known issue with the original engine small oil ports. Brought my vehicle to a Kia dealership and their diagnostic procedure was to replace the sensor and reflash the ECM. My problem is, ever since they did that, the knock sensor has not gone off and no codes are being generated. Engine is knocking worse than before. I believe they reset the parameters to a level that basically is making the knock sensor useless. They are buying time and mileage in hopes the engine out lasts the warranty. It is a manipulation of factory settings and fraud causing the consumer future issues.

    I was driving my 2018 Kia Sorento up a hill going about 40 mph. It suddenly lost power and I had to pull over. No lights showed up on the dash warning me anything was wrong. I was draining oil like crazy and it was all over the engine. I had it towed to a mechanic and then the dealership. A bolt from inside the engine blew and tore a hold in the valve and head gasket. That’s all I know now. I had purchased my vehicle pre owned certified, and Kia is not honoring the warranty even with extended warranties. This happened at 87,000 miles. I have seen other reports of Kia Sorentos having issues with their engines. Please help.

    My 2018 Kia Sorento sticks and when pushing the gas and the RPM jumps up. The car also stalls out and then turns right back on. It shakes and makes a funny noise as well.

    I have a 2018 Kia Sorento that I absolutely love. As of late, I have noticed that 1,000 to 1,200 miles after my oil changes- I am getting my engine oil light on, on the dash. Upon checking, again after only 1,200 miles after an oil change- my engine oil was completely gone. The dipstick was almost bone dry. I took my vehicle in to have an oil leak test, because I instantly thought I had a leak due to that being an excessive amount of oil missing. However, there is no leak. It passed the leak test, and there is also no oil in my driveway. Upon talking to the Kia dealership this is apparently a very known, and prominent issue with this vehicle. I am "out of warranty" with Kia- so I am unable to file a claim with them to have this repaired. This is unacceptable for them to know that this is an ongoing issue, and they are not standing behind their products. I have thankfully purchased an extended warranty with an outside agency, that I am filing a claim for. However they will only cover the issue at Kia if the "engine oil consumption test identifies the failure" From what the service man said to me, from Kia- the two "failures" that they have, are either needing to have a combustion chamber cleaning done, or an entire new engine dropped in. Both of which leave me without a vehicle for WEEKS. As a mother with young children, and also a mother that works and has a one vehicle home- this leaves me needing to rent a car for however long that may take. Looking into this further I have seen that Kia Sorentos with the GDI motor (like mine) from NEWER years, have a recall on their engines for a very similar case and very similar situations with them burning excessive oil in their vehicles. I strongly think that the lower year makes and models need to be investigated, as well. I absolutely think that my vehicle needs to be included in this recall as I have gotten and maintained every single oil change, and service needed to my vehicle since I have purchased it in 2020.
