KIA Complaints

The contact owns a 2015 Kia Soul. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power, with smoke coming from the engine compartment. The check engine warning light was illuminated. The contact pulled into a parking lot, where the engine overheated, and there was oil leaking from the vehicle. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The engine was replaced. The contact stated that later, while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken back to the mechanic, where it was diagnosed and determined that the catalytic converter had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 123,000.

My vehicle has been slow to start and I have had all other issues come on on my vehicle as far as lights as far as the forward collision warning light has came on and the check driver attention warning light has come on as well while I’m running my HVAC past the level 2. I have also had my battery tested and that has tested fine. I have had my alternator tested and the first time it came back good the second time it came back failed and the third time it came back good.

I bought the car 2 yrs ago come April and it's had nothing but issues. I've had one recall did which was the knock sensor however now the check engine is on and it's smelling like rubber my brakes are wearing like an eraser and my engine just feels sluggish. The code is p0420 which from what I understand is a catlic converter and I read online there is a recall for that with kia . I've spent a lot more than what I paid for the car not even 2 yrs ago and every place i take it has a new opinion and none of those have any connections with the code so I need help

Car oil light doesnt come on , only when almost gone. Car stop and slugish on highways and automatic turns off , this issie since the update

Driver window rattles at all speeds. Not a big safety issue but if it breaks because of the rattle or it falls down then it could. When I put a crack in the window it stops

The engine lost cylinder 3, piston came loose and broke the spark plug. This happened because the rod bearing came loose which has been a known issue with Kia. There’s already been a class action law suit, and recall with warranty. Now the Kia dealership in Lynchburg has refused to honor this warranty. Stating they can’t do the required rod bearing clearance test because the engine doesn’t have compression. The engine has no compression because the rod bearings came loose and shoved the piston into the head.

The brakes are very spongy all of the sudden, making it very difficult to stop quickly. This is a major concern considering how many people are having this issue.

My vehicle has an ongoing acceleration problem that feels like the engine and transmission are not communicating correctly. There are times when the vehicle will not accelerate even though the RPMs increase. Instead of picking up speed, it feels like the engine is pulling the vehicle back. This creates hesitation and uncertainty about whether the car will respond when I press the accelerator. This happens most noticeably at lower speeds (around 30–40 mph, often near 30 mph), where the RPMs may rise on their own even if I am maintaining steady pressure on the gas pedal. It also occurs when I need to accelerate quickly — such as merging onto the freeway or joining the flow of traffic — and the vehicle feels like it resists gaining speed. Even when I press the pedal gradually and correctly, the vehicle struggles to accelerate and the engine revs without the car moving forward as it should. I reported this to the dealership. They ran diagnostics and told me no issues were detected. They also stated they cannot take action unless they can re-create the problem themselves. Because this does not happen every time, recreating it on command is very unlikely, leaving me without a solution. This is a safety concern because hesitation or failure to accelerate properly during merging or crossing traffic increases the risk of collisions. The problem remains unresolved.

My vehicle repeatedly fails to recognize the key fob even when it is in my hand or inside the vehicle. Because it is a push-button start system, proper fob communication is required for unlocking and driving. When recognition fails, the vehicle will not start and I have been stranded. During the first of these failures, I called the dealership because I was stranded and needed immediate assistance. They instructed me to remove all passengers, close the doors, and then hold the unlock button on the key fob for 10 seconds and press lock/unlock six times in sequence. They also advised me not to use the door-handle lock/unlock button and to use only the fob buttons. This temporarily restored function, but a new vehicle should not require a manual reset procedure to start and operate normally. On two separate occasions, this problem also triggered the vehicle alarm, which was extremely difficult to silence. This does not happen every time, making the vehicle unreliable. One incident occurred while transporting special-needs children and an elderly passenger, and removing them from the vehicle to perform the reset was difficult and unsafe. The dealership later ran diagnostics and found no fault codes. I also replaced the key fob battery, but the issue continues. I have seen other owners online describing the same key-recognition failures, indicating that I may not be the only person experiencing this. This is a safety concern because the vehicle can fail to start without warning, and the alarm activation increases confusion and stress. The issue remains unresolved.

My 2016 Kia Sedona is affected by Safety Recall SC175 (Front Passenger Seat Occupant Detection System Wiring Harness), documented here: [XXX] . Kia and the servicing dealer, Rick Case Kia, report to NHTSA that this recall was completed in 2019. However, the defect described in SC175 is still present and easily reproducible. The dealer continues to insist the repair was completed, but the symptoms match the recall description exactly and the issue now poses a clear safety risk to the front passenger. I have repeatedly informed Rick Case Kia that the recall was not performed correctly or was never performed at all. Despite this, the dealer refuses to inspect or correct the issue and Kia Corporate refuses further action based solely on the dealer’s claim. This has made it impossible for me to obtain the required recall remedy. The vehicle was taken to the same dealer multiple times between 2019 and before the vehicle reached 10 years of age for other safety recalls. If SC175 had truly been completed, the issue should not be present. If it had NOT been completed, the dealer should have been notified in their system during those visits. This suggests that misrepresentation or incorrect reporting may have occurred. Because Kia Corporate relies entirely on the dealer’s incorrect reporting, I cannot obtain the required repair from any Kia dealer, and the safety defect remains unresolved. I am requesting NHTSA review this case as a potential recall-completion misrepresentation that is preventing me from receiving the mandated safety repair.
