Knock sensor1/8/2024 Kia addresses issues and stands behind it better than any other manufacturer I have seen.Īll cars today have recalls and issues, no manufacturer is immune to it, it's across the board. There are issues with the earlier Theta engine that are known and being replaced by Kia with even over 200k on them as I've done it under warranty. People do not maintain their cars and seems like Kia gets a lot of entry level buyers that do not keep up with it, it's just a fact, I speculate that it's because they're a good value and perceived as cheaper. Had a Telluride come in earlier today for it's 1st oil change with just under 15k on it. Ivt is bad and it is a recall although I've yet to do one on a car that came in and had the recall performed on it so if people bring them in it doesn't seem to be an issue but most ignore it forcing a trans replacement. It has 24k on it and I'm quite certain it's maybe had one oil change as the oil is so filthy, some sludge buildup is already visible and the car is just trashed all over. Sure it does, as we speak I'm working on a 2020 Soul 2.0 for the IVT replacement. If I remember right the manual said oil changes every 7000 miles? I have always changed our vehicles every 3000 miles. I am sure many of them are due to poor maintenance. It just worries me reading about all of the engine failures etc. We love the car because my wife has back issues and this car is very comfortable for her. In case this happens to any of you on the road. Wait a few minutes and without your foot on the brake cycle the ignition a couple times and it should reset itself. He also mentioned if it happens again with the car in limp mode just safely pull over and turn the engine off. He told me to just bring it back when the light comes on again. So in my case they just need to re flash the computer a little it seems its too sensitive. It turns out the computer up date they did a couple weeks ago makes the knock sensor more sensitive so it will set the check engine light early because so many people were riding around with their engines knocking and these things are blowing up. Since I have a appointment tomorrow and since I already erased the code for the knock sensor i talked with the service manager while there. I stopped by the local dealer today and picked up the PCV. I recommend popping in a new PCV at around 60k as well to keep everything singing not because they fail but they are inexpensive and a good idea in my opinion to keep fresh. If you are changing your oil regularly like you have and treated it to some new plugs I think you are doing well. Back in the day on my high mileage cars I used to run a cup of water and a cup of trans fluid by sucking it in with a vacuum line to clean the carbon off the piston and the combustion chamber, obviously port injected so didn't have to clean valves. Too many variables really to speculate but all GDI engines not just Kia suffer from this, companies like VW actually recommend to pull off the intake and use sandblasting with walnut shells to clean the intake valves. ![]() ![]() I have seen engines with carbon buildup (higher miles than yours and not much maintenance) perform poorly because the ECM is pulling so much timing and a good carbon cleaning has fixed them (fuel induction service with some very industrial chemicals run into the engine through a vacuum line for a half hour) The amount of carbon buildup varies with a ton of conditions such as cold starts, health of the PCV valve, driving such as short drives without a full warm up or long highway drives etc. Misfire strategy is a little different and it actually calculates misfires based on the acceleration of the crankshaft between the different firing cylinders and it gets that info from the crank position sensor so the 2 are but also aren't related necessarily. This strategy also often falsely determines that there is engine knock such as that from a rod bearing going out. Once it can't pull enough timing or make other adjustments it throws the light and engages limp mode with the assumption that you are about to damage the engine by continuing to operate it that way. the ECM pulls timing to try to eliminate the knock. So the knock sensor strategy is not well explained but essentially when there is some knock from misfires or just spark knock from low grade fuel, carbon buildup, not good spark plug etc.
