2018 KIA SOUL gas pedal stopped working while driving on interstate 695. On April 7, 2024 my car displayed the following warning message on the dash while I was driving on the beltway. -??Transmission Temp high please stop safely-??. The warning light went off, but I took my car to the Koons Kia service on April 9, 2024. A few days later I was informed by the dealer that the transmission needed to be replaced and that the engine had sludge. I was later informed that the clutch actuator also needed to be replaced. The Transmission was covered under warranty and Koons Kia allegedly did the repair. I picked my car up on April 17th. The very next day (April 18) the transmissions started making noise. I contacted the dealer on the 18th and reported the concern. They told me to bring the car back on Tuesday, April 23rd. At no time did anyone warn me of the potential safety issue. I do not know what the mechanics at Koons Kia did, but the car was worse and more dangerous after the repair. Unfortunately, on April 22,2024 while driving on interstate 695, my car started to lose power and suddenly slow down. Cars rushing by and my car would not accelerate when I applied the gas pedal. The warning message -?? Transmission temp high stop safely -?? appeared again. I pulled over on the shoulder until the car cooled off. This time there was a smell along with it. When the car cooled off, I slowly drove the rest of the way with my hazard lights on. I contacted Kia dealership, Kia roadside assistance, and Kia customer service. No one warned me of the extreme safety issue nor did they offer any assistance with getting me home or with getting car back to service department. My car is back at the dealership. But this is a major safety issue. The gas pedal stopped working without warning while I was on interstate 695 going well over 50mph. There were other cars zooming by. very dangerous. I could have been hurt or someone else could have been hurt.

Bought this vehicle used with 32k miles. Have experienced a judder when accelerating since we purchased it. This a known issue with Kia. I sent it to a dealership and they replaced a fuel injector and said that was the problem, it's not. Got the car back and it is still malfunctioning. This issue was reported on this vehicle previously when it was brand new. I need this issue fixed.

My vehicle randomly started making a knocking noise. We took it to our local mechanic who stated he has seen a lot of these come from the Kia line lately. the knocking noise comes from the rods. He said the cost to get this repaired would be $4,000-$5,000, since the bottom portion of the engine would need to be replaced. This car is not driveable. We are the 2nd owners and the car only has $65,000 miles on it. We bought the car from carmax in November 2021, and they did a full investigation and found no fault with the car. The rod knock started in March 2022. We are hoping there would be a recall on this, as we see from forums, we are not alone. The check engine light did not come on at any point.

Driving on Route 79 on Labor Day weekend, at 70mph in the passing lane, my 2018 Kia Soul+ with 77574 miles refused to accelerate and then the engine completely stopped. We were able to get to the side of the road unharmed but the engine was completely dead. We called triple A and has it towed to a local garage I called Kia corporate because the car is not yet 5 years old and the garage thought it might be under warranty. The Kia consumer line 800-333-4KIA took 5 hours to reach a human but gave me a claim number and the representative said it had to be seen at a dealer but that I was likely covered. I advised I was the second owner and that when I was trying to find their number I tripped upon an optional product improvement campaign I was not made aware of. I was very suspicious and surprised. I asked repeatedly what happened if it was towed and not covered. And they said to call back but I should be ok. Kia towed it to the dealership. The dealer took 2 weeks to look at it and make a determination. They are stating that because I did not have the improvement campaign completed that they will not cover the engine. I was told to call back Kia corporate which I did and after 3 hours of waiting I was informed that there was nothing they can do that I was out of warranty because the improvement campaign that I was never notified of had not been completed on my car. They state that they sent a letter in November of 2021 but I did not receive it. I'm now being charged diagnostic fees by the dealership and they still want $11,000 and 4 to 6 weeks to do the necessary repairs. I still have a loan on the vehicle for $12, $321.46. I called Kia corporate back they will do nothing to assist me because it is out of warranty and I did not have the campaign improvement done because it was never sent as notification to me via email or phone and I did not receive the document they claim to have mailed. The supervisor I spoke with told me that there is nothing that KIA can do.

Follow up to complaint number 11446088 submitted on 1/3/2022 Car was taken to dealership on 12/18/2021 for check engine light with code P1326 and car entered a limp home mode that limited engine RPMs to 1800-2000 RPM. I received a call from dealership on 1/12/2022 informing me that car was ready for pickup. Picked up car on 1/13/2022, where invoice says the following: "77240 p1326 DTC 39250fln/39250rq0 check engine light on arrival, trouble code p1326. bearing clearance test was not able to be performed due to no tsb opened yet for this year make and model. opened a pwa case performed compression and leak down test passed. performed few test tech line required and came to a conclusion that engine replacement is not approved, knock sensor was approved under warranty vehicle will be shipped with no dcts over 2 drive cycles of 10 miles" Two notes: (1) it appears that the manufacturer informed dealership that it would not approve replacing the engine, despite the engine being under warranty, because no recall has yet been issued on the 2018 model year. (2) the dealership say they performed 2 drive cycles, each of at least 10 miles. This was not done, as shown on the mileage in/out readings on the attached invoice (see attached document, "06 - 2022-01-12 - Kia Carson - Invoice"). Attached are 8 documents for all the documents I have related to this problem: (1) NHTSA - Vehicle Complaint - 11446088 - 2022-01-03 (2) Kia Product Improvement Campaign Letter - 2021-11-16 (3) 01 - 2021-12-04 - Kia Carson - Workorder (4) 02 - 2021-12-04 - Kia Carson - Invoice (5) 03 - 2021-12-07 - Kia Carson - Workorder (6) 04 - 2021-12-07 - Kia Carson - Invoice (7) 05 - 2021-12-18 - Kia Carson - Workorder (8) 06 - 2022-01-12 - Kia Carson - Invoice Answers to questions above: (1) not available for inspection.

On 16 November 2021, Kia sent a letter for a Product Improvement Campaign to install software called "Knock Sensor Detection System" ("KSDS") on my 2018 Kia Soul Plus. The software update was installed on 4 December 2021. The 16 November letter noted that if KSDS detected a problem, the car would enter a limp home mode that limited engine RPMs to 1800-2000 RPM and the Malfunction Indicator Lamp ("check engine light") would blink continuously. On 17 December 2021, the check engine light started to blink continuously, and the engine RPMs never exceeded 2000 RPM. I took the car to the dealership on 18 December 2021. The car is not safely operable. The dealership told me that they needed technical assistance from the factory, which they have not yet received as of 3 January 2022. I'm reporting the issue because it appears to be related to the known engine manufacturing defects in Theta, Nu, and Gamma lines of engines, and that these issues persist beyond the 2011-2016 model years (for which a recall has already issued) and at least into the 2018 model year. Answers to questions: (1) powertrain/engine failure, possibly other system(s) (2) safety risk is known fire danger in Theta, Nu, and Gamma engines (3) dealer is currently diagnosing/confirming the issue (as of 1/3/22) (4) only dealer has inspected vehicle (as of 1/3/22) (5) no issues prior to 12/17/21, when Malfunction Indicator Lamp ("check engine light") started to blink continuously and engine RPMs were limited to 2000 RPM.

2018 kia soul+ with 2.0l engine has developed a rod knock at 86k miles. Kia customer service was made aware of the issue and has refused to to repair the vehicle. According to a kid certified technician at a kia dealership, the issue is the same as other kia vehicles with a recall for, "connecting rod excessive wear". Customer service was made aware of these findings and still refuses to issue recall. Engine currently runs, but can not be run for very long or driven due to eminent risk of catastrophic engine failure.

I have a 2018 Kia Soul+ and recently there is a burning smell coming from the car especially when the A/C is on. I took my car to the dealer regarding the problem, but was told that they did not see anything wrong or smell anything burning on the car. The problem happens mostly while driving on the highway. I'm afraid that the car is going to catch on fire. The car also loses power while driving ex. I can be driving 60 miles and all of a sudden the car starts to decrease in speed and you have to rave up the car to get it going again. Not good at all.
