I am the owner of a 2018 Kia Soul. On May 19, 2024 I broke down on a highway in a dangerous construction zone. Just prior to this my oil light came on, so i put some in to be safe until I got home to let engine cool. No other warning lights or messages came on. Got a little further down the road and the light came back on with the engine now making noise. I managed to find an emergency pull off and as soon as I pulled off the car died. I had it initially towed to my mechanic but when they looked at it they said had to go to dealership it was the Engine and possibly under recall. Had towed to dealership on May 21, 2024. They were backed up and unable to look at it until after the holiday. They finally got to look at it on June 3, 2024. It does meet the requirements for the Kia Engine Recall. Here is where the plot thickens, Kia, not dealership, denied the recall work because the update was never done. I just received the update notice the end of March 2024. Due to me being disabled and I had some doctor appoints to keep I just cleared my schedule to make the appointment and was planning to do that when broke down with no warning. I called Kia customer service and they said because I did not have the update done it has to fall under the Class Action Settlement and they will not cover it. Now under the Class Action Settlement, you need to pay out of pocket and then seek reimbursement. However, the work has yet to be done and I am disabled and on a fixed income. It is now June 10,2024 and the Kia dealership still is not getting a straight answer from the warranty company on whether they will accept the claim and cover it or not. Meanwhile, I am putting a friend out to help me. What is a person to do?

Update to case 11587168: Ian (Service Writer) at HW Kia told me 3 weeks ago Kia was approving engine replacement, he was ordering the engine & to provide all service records so they have them on file. I provided receipts for 2 oil changes I had done by a non-Kia dealership auto service. All other service records are accessable via KIA & CarFax as Napleton Kia St. Peters & Plaza Tire Service had done all other oil changes/ maintainence on the vehicle. The Thursday before Memorial Day I get an email from Ian that now Kia is denying the engine replacement. I am now waiting to get a contact from the RPSM (Regional Parts & Service Manager) as to why since I provided proof the vehicle was properly maintained. This is a wrongful denial in my opinion.

Additionally, the contact observed a light knocking sound coming from the engine compartment. The vehicle was stopped in a parking lot and t…

My granddaughter was traveling to Florida from Texas for a short vacation on [XXX] 2024. Car just lost power and slowed in the middle of the interstate traffic, no lights, warnings or anything. Thank God she was able to get to the side of the highway without getting hit. It was knocking and clattering in the engine. Killed it and let it rest a bit and checked the oil and it was [very low, added some oil and started it back up, but it still was knocking and not running. Had it towed to an independent garage in Crestview Fl. The mechanic diagnosed the engine with a possible bent valve and loose timing chain. The car has 104000 miles on it. We had the oil changed at 102000 and have had oil changed regularly at 5000 miles or less since we bought it in March 2022. We still owe a loan on this car. Mechanic said the engine would have to be replaced and quoted 7000.00. We cannot afford this. We are the 3rd owner and was not informed of any safety recalls or software updates until the Mechanic told us about the Class Action Lawsuit and the issues with the engines in Kia and Hyundai. Kia is not forthcoming with this information and does not notify but only the 1st owner. This is ridiculous and not right to do the consumers this way. We bought the car from a Nissan dealership in Mckinney Tx and was not told anything about this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX], 2024 had a complete break down while driving on the highway on the way home from work. No warning light prior to the incident. Towed via ERS on my auto insurance policy to Plaza Tire Service, [XXX] . They replaced spark plugs and coils. Still sputtering and code on cylinder 3. Then taken to HW Kia of [XXX] in Ballwin, Mo (this was the closest dealership that said they could get to it right away). Has been there ever since (going on 2 months now). What I have been told has be done by Ian, Service Manager: Compression test done, no compression in cylinder 3. Warranty company (JMNA) sent out inspector. 2 weeks later warranty company asked dealership to do a full breakdown of the engine. On [XXX] got call from Ian that warranty company denied fix under warranty because the damage is to piston rings. (Month and a half just to get this determination from the warranty company) Ian told me that this is a known issue by Kia so he is requested engine replacement directly from Kia Corp. As of today ([XXX], 2024) I am still waiting to hear back if this replacement has been approved. Previously told by Ian (when I initially dropped off the vehicle) that once/if approved it will take approximately 10 days to get a new engine ordered and into the dealership.

While driving vehicle, engine reduced power and went into a limp mode, pulled off Highway and stop. Check engine light came on and blinking. Later found motor had lost over three quarts of oil. Now engine knock and have been advised by mechanic that engine is about to throw a rod thru the the side. Vehicle has had oil changes at 5000 miles intervals thru out its 124,000 miles on the road also oil checks often too. Now we are without a vehicle with a damage engine. I understand thru research that this is a common problem for this type vehicle and motor.

Car stalled in the middle of the road while driving. Took it in to dealer ship for a recall to get this repaired or flashed. Engine burning excessive oil. Car has always been kept up with maintenance. While operating the vehicle the car stalled due to low oil compression. Vehicle has aprox 155k miles. Check engine light has came on. Due to the issue that car engine is burning oil there is a new permanent code p0420 which is a bad catalyc converter since the cars emission system is failing. Car has been sitting at home for about 1 month or longer as we don’t drive it and are still financing the vehicle
Second time in last six months car went into “limp mode” with the knock sensor. First time it was “just” a faulty knock sensor and under warranty. Happens again now it’s the all too well known the oil is burning too fast on this engine. Kia/hyundai will not take this under warranty as it is not a rod bearing issue while numerous…

Second time in last six months car went into “limp mode” with the knock sensor. First time it was “just” a faulty knock sensor and under warranty. Happens again now it’s the all too well known the oil is burning too fast on this engine. Kia/hyundai will not take this under warranty as it is not a rod bearing issue while numerous owners have the exact same issue. This cars engine can probably fail at any time with this oil issue continually happening. The cars oil has been maintained per manual and was not expecting an oil change yet the level is way too low already (3000ish which is way before the 5000 mile mark per owners manual and Kia)
