The contact owns a 2015 Kia Optima. The contact stated while driving 55 MPH, the vehicle shut off with several unknown warning lights illuminated. An independent mechanic spotted the contact on the side of the road and helped. The mechanic was able to restart the vehicle; however, the vehicle immediately shut off with a loud clanking sound and a burning odor coming from the vehicle. The vehicle was later towed to the residence. Despite the failure, the contact was able to drive the vehicle to an independent mechanic and was informed that the VIN was included in NHTSA Campaign Number: 21V331000 (Service Brakes, Hydraulic). The vehicle was driven to the residence and a mobile mechanic inspected the vehicle. The contact was informed that the VIN was under recall and was advised to take the vehicle to a dealer for assistance. The vehicle was towed to a dealer and was diagnosed with engine failure, which voided the recall due to the diagnostic test. The contact was offered a buyback which was refused. The contact was then referred to the manufacturer and was informed that the vehicle was out of warranty and that any repairs would be an out-of-pocket expense. The contact drove the vehicle back to the residence despite the failure and the vehicle repeatedly shutting off. The contact called another mobile mechanic and was informed about a recall and related the failure to the recall. The vehicle was not repaired. The failure mileage was approximately 130,000.

I am writing to file a complaint regarding a 2015 Kia Optima I purchased from Synergy Auto Deals LLC (formerly located at 1001 S State Road 7 Hollywood, FL 33023). The dealership failed to disclose a critical open safety recall on the vehicle at the time of sale, which I believe violates consumer safety standards and puts me at significant risk. Details of the Complaint 1. Undisclosed Safety Recall: • The vehicle has an open safety recall that was never disclosed during the purchase process. I only became aware of the recall after the sale, which has caused significant inconvenience and concern about my safety. 2. Dealer Misrepresentation: • In addition to failing to disclose the safety recall, the dealership misrepresented other aspects of the sale, including the price and fees, and employed deceptive practices during the loan approval process. 3. Expenses Incurred: • As a result of these issues, I have incurred additional costs, including: • Gas mileage to address the recall issue • New tires • Monthly payments for a vehicle that was sold under false pretenses • Insurance payments • Costs for repairs related to the recall Vehicle Information • Year: 2015 • Make: Kia • Model: Optima Desired Resolution I am requesting the NHTSA to: • Investigate this dealership’s practices, particularly regarding the failure to disclose safety recalls. • Assess whether this case is part of a broader pattern that may require additional enforcement actions. • Provide guidance on any potential r

My vehicle is painted in the Snow White Pearl. The paint started out looking almost "bubbled" but definitely showed serious signs of delamination, quickly after noticing the delamination, the paint flaked off in relatively large pieces all over my vehicle. There is paint missing from the hood, the roof, the back passenger side door, the quarter back panel of the passenger side, and one chip on the driver side door. I reached out to KIA regarding the issue and was told that there is nothing that can be done. I have gotten to the point that i cannot stand to look at the car I once loved so much, it is a shame. KIA is a company that I have been loyal to when it comes to vehicles and I have only owned KIA's since 2008 but after this issue I am almost embarrassed to show up anywhere driving this car.. and even more so I am upset that KIA will not do what it takes to remedy this issue for myself and so many others.

When I was driving my car had stopped driving, the engine light had popped up. I put a new battery, and starter on to see if that was the problem, but it wasn’t. I then took the car to battleground Kia in Greensboro, NC. They confirm that the engine had stopped working due to being locked up and it had a recall on it. First they said they can’t fix the engine without my registration and license, I turned that in then They said they will not fix the recall if I don’t have enough evidence of oil changes which I’ve handed over to them multiple times. I thought a recall was suppose to be fixed without hassle. My Kia advisor is Matt Cates. Email:[email protected]

I was driving on the interstate, going 80mph in the passing lane passing a semi. (speed limit in SD) my car died. No noises, no warning lights NOTHING. Just lost ALL power. I was able to coast to the side of the road. I towed it to Kia to find out my engine seized. It IS part of a Class Action Lawsuit but they should be recalling these engines BEFORE they go out. Imagine if an unexperienced driver was driving and lost all power, or if it was icy, or someone was behind me? This is unacceptable these engines are failing and putting lives in danger

My 2015 Kia Optima has always had issues with the passenger side window getting stuck. Apparently there was a technical service bulletin, and recalls for the 2016 model but not 2015. My son was driving the vehicle the window got stuck and then shattered into 3 pieces. This is a HUGE safety issue and KIA does not want to take any accountability for this. A recall needs to be issued immediately to protect people from shattering glass!!!!! I did open up a case with KIA and so far NOTHING case#[XXX]. Meanwhile my car has been sitting at Beck and Masten Kia in Tomball waiting to be repaired. Why must we pay for this when I complained for months it was a problem and my warranty just expired!!!!!!!!!!!!!!!! This is NOT safe. Please issue recall and investigate immediately!

After checking it, they informed us that due to the update that was done to the vehicle it triggered faults in the battery. They informed us we would have to replace the Hybrid Battery that would cost us about $13,000.

I have a 2015 Kia Optima never had any problems. Last Sunday it starting rattling from the engine, changed the oil the following Saturday and drove it to see if it made it any better. Within 20 mins the noise in the engine from knocking was so bad, my car was trying to die on me at red lights. Luckily, I was able to make it home. Checked the oil that was just changed and drove maybe 25 mins is full of metal shavings. Called Kia and they are trying to say that because a recall wasn't completed before I owned it that I am not eligible for a engine replacement, even though when i bought this used car from a Kia dealer they should have seen and completed this recall. Now I have a car with a bad engine that I still owe 5K that I can't even drive to trade it in.

I was driving on the expressway onto the exit ramp going about 75 mph when my car suddenly slowed down even though my foot was on the pedal as i kept trying to drive, it was slowing down. The temp gauge was exactly in the middle and the rpm was at 0. The mph was at 60 mph even though it was slowing down it didnt change on the reader. When i realized the mph on the reader was not changing all the service lights came out on the dash. So I idled to a stop on the side of the road when I got out of the car I realized there was smoke coming from the hood and it had a really awful smell of something burning. I know the engine didnt over heat because the coolant reservoir is full and the upper radiator hose had pressure. Ive been having an issue with burning oil so I topped it off with a qt of oil. I left the car off for about 2 hours and then tried to start it and the engine would not start , the break pedal became hard to push down but the burning smell got worse. So i decided to turn the car off again. Meanwhile im still stuck on the side of the road. I watched a couple of youtube videos and there are many people having the same issue with the radiator fan, or a leak in a pipe or hose, or some sort of sensor.
