P1326 code flashing engine light knock sensor went out 3 times in 6 months and just replaced it again and this time engine light didn't go off I was reading that there was a recall on this but apparently mine doesn't state it. Car cannot pass emissions if engine light is on and the 15th of June is approaching. The car doesn't make any sounds or nothing.

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.

The contact owns a 2021 Kia Soul. The contact stated that while checking the engine oil level, the contact noticed that the vehicle was consuming excessive oil. Upon inspecting underneath the vehicle, the contact's husband did not find any leaks. No warning light illuminated. The vehicle was taken to an independent mechanic, where it was determined that the piston oil rings needed to be replaced, and the engine was consuming excessive oil. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V259000 (ENGINE); however, the VIN was not included in the recall. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall due to the vehicle mileage. The approximate failure mileage was 82,000.

On startup, the engine took about an extra second to fire. The starter cranked noticeably longer than normal before the car turned on. Shortly after, I pulled out and turned onto a street. When I pressed the accelerator, there was no response at all. No rev increase and no acceleration. The car would not pick up speed. I switched to manual shift mode to try to force a gear change. When I changed gears, it took a couple of seconds to respond each time, much slower than normal. I managed to coast/limp to a nearby gas station. I shut the car off and restarted it, and the problem cleared completely. The car has driven normally since.

The car returned P1326 and had multiple misfires and audible knocking, the dealers will indeed fight the already existing class action warranties. Was sent home and told to “drive the fuck out of it”, to which the car did not make it home and blew gasoline into my cabin while driving on the highway. Almost passed out, and am still fighting Kia to actually address the defective rod bearings. I personally would fight tooth and nail over a 5 dollar problem, but this is something they do nationwide and can cause serious injury or death. If it weren’t a 200 LB man driving the gasoline shooting into the cabin would absolutely cause a knockout. To the time of this report they are still trying to disregard the rod bearing issue and send me home with fixes to problems caused consequentially.

States having problems with oil lost, but only inside the motor as if the rings are faulty
