1 Engine Knocking Noise problem

Failure Date: 04/17/2021

While driving my car down the freeway going 77mph my car failed to shift while going up a hill and started making a knocking noise while in cruise control. Then out of cruise control the car made a loud bag and pop and smoked. We pulled over and the car motor had then been seized and would not start. Kia motor is declining to replace my motor based on the product improvement campaign of 18v907000 because they state that I failed to have the car inspected with this campaign. Kia motors told me that they sent the product improvement campaign notice to the previous owner in 2018 but that it was still my fault that the inspection was not done and the knock sensor wasn't added. I let them know I knew nothing about this because I never received the letter because it was not sent to me and I was not notified and the consumer affairs supervisor said it was still my fault for not calling kia when I purchased the car in 2015 to let them know I am the new owner and to give them my information.

2 Engine Knocking Noise problem

Failure Date: 12/28/2020

My engine died while passing a vehicle on my way to work. No warning light, no knocking sounds, nothing. It just died. Had to get in front of vehicle I was passing and coast to the side of the road. Would not restart. Sat in the cold for 3 hours without heat on a desolate road with no cell service. No town within walking distance. My mechanic said the motor is locked up and I'll need a replacement. 103,825 miles on it. Warranty ran out at 100,000 miles. Apparently this is common in these vehicles and kia is involved in a class action suit for this and other malfunctions. Called kia and they were not helpful at all. I'm a nurse carrying for covid patients and have no vehicle to get to work. I still owe $13,000+. I bought it in 2018.

3 Engine Knocking Noise problem

Failure Date: 12/05/2020

Took my car to the mechanic for a second opinion regarding low beam lights shutting off when I turn on the high beams. This occurred frequently when using high beams. Also, my headlights (low beams) consistently burnt out. Had to install 2-3 new bulbs in each headlight (within 1 yr. ). Mechanic said problem is more than just the lights, the knock sensor was bad and needed more work than what they were willing to do and recommended me going back to kia. Driving home from my mechanic, I was on the surface streets to get on the freeway, a knocking noise occurred when accelerating, sounded like it was going to throw a rod, which led me to check the oil. My oil changes are completed on schedule and was not due for another oil change for 3,000 miles. The oil was bone dry. I put in 4 quarts of oil and drove on surface streets, back to my mechanic. Mechanic said it is about to throw a rod and that I needed to drive it slowly and get it to kia. As I drove the car home on the freeway, I was in the number one lane, passing a semi-truck in the number two lane, car started shaking, all the lights started blinking, the orange steering wheel warning light went on and the entire car completely shut down. I had to coast to the shoulder on the freeway. I had no hazards or blinkers. Tow truck arrived and checked my oil, he said there were metal shavings and barely any oil. Towed the car back to the mechanic and they said I needed a new engine. Had the car towed to my home and it now sits in my driveway. Prior and during all of this, not one time did any warning lights on the dashboard go on (other than the one steering wheel light when the car shut down).

5 Engine Knocking Noise problem

Failure Date: 03/07/2020

While driving a knocking sound occurred and the engine temperature began to rise. Eventually the SUV begins to stall and starts to lose power. Once stopped (pulled over safely) I noticed that the coolant is overflowing and gushes out along the side of the hood. When adding more coolant, it continues to overflow once driving and the engine temp rises again and begins to stall. Seems to not be able to hold coolant.

6 Engine Knocking Noise problem

Failure Date: 03/02/2020

Engine started making a knocking noise upon acceleration and at initial startup. Engine has only 53,000 miles on it. I drove the vehicle home, parked it and immediately made an appointment with the local dealer to diagnose the problem. I was able to drive the vehicle to the dealer (less than 5 miles). After much runaround and little explanation, kia is telling me that the engine needs replaced due to sludge (something I have verified with independent mechanics is very unlikely with a 5 year old vehicle and reasonably low mileage). The oil at time of drop off was verified to be clean and full per the kia technician. I provided kia with records per the warranty agreement and they are denying my claim for replacement. Every excuse for denial has included additional terms not outlined in the written warranty agreement (receipts that include minute details or the excuse that 'dates don't match' when I haven't provided any dates nor is any required service based on time (only mileage)). The vehicle is still under the bumper to bumper warranty (5 years/60,000 mile) and powertrain warranty (10 years/100,000 mile). Many other vehicles of the same year have had similar issues, yet kia is refusing to acknowledge the problem or expand previous recalls for the same model and issue.

7 Engine Knocking Noise problem

Failure Date: 02/06/2020

I have had my Sorento for a little over a year. In February my engine started making a knocking noise. I took it to a dealership and I was told I needed the engine replaced for 8000. After reviewing I seen that this is a common problem and there are recalls for alot of their engines. Since I purchased my car used, there is no warranty and they refuse to fix it even though it is a common problem with their vehicles. I was told my engine had sludge even though I had my oil changed in November and my car is still under 79000 miles.

10 Engine Knocking Noise problem

Failure Date: 07/10/2018

I was driving to work yesterday morning (7/10/18) on route 15 in sussex county. My speed was approximately 65-70 miles per hour. I heard a knocking sound, which alarmed me. It went away, and came back, off and on, while driving, a sound that I have never heard before with this vehicle, ever. No lights came on, no indicators, etc. I contacted newton kia, where the vehicle was purchased, and was told that they couldn't fit me in until Friday. I made an appointment, but after doing this I decided to contact one closer to where I work, which is on rt. 10 in denville, NJ. Gateway kia. I brought the vehicle in and had them check out the noise. I was contacted and told that it was the engine, that it would cost $7100. 00. The way I was notified was as if I have $7100. 00 just sitting around, which I don't. The engine, the engine, no warning, no nothing. I picked up the vehicle, and drove it home, still hearing the knocking noise off and on. I attempted to go to work today, 7/11/18. The noise became worse about a block from my home. I turned around and came home, shut the car off, smoke came out from the engine area. Let me make something very clear to whomever reviews this information. I am not paying for this repair, kia is. First thing you are told that you are over your warranty. I just turned 102,000 miles, have had no prior issues. This happened out of the blue, no prior noise or problems. I am now driving a rental, I need to get to work, I need my Sorento fixed, and I am not paying for it. I am also going to be reimbursed for this rental. I, again, have had no prior issues with my vehicle. I am very upset about this, so what is going to be done about it.

12 Engine Knocking Noise problem

Failure Date: 10/14/2017

"takata recall" we have around 41000 miles on our 2015 kia sorrento. My husband took a position working approximately 2. 5 hours away from our home and making a daily commute of 5 hours each day to work. We have never had any trouble out of our Sorento. In Saturday, October 14, 2017 after a long day at work he was traveling home and was about 1. 75 hours into his 2 hour commute when our Sorento started making a terrible knocking noise. No light indicators came on to indicate what could possible be going wrong at the time. He got over in the slow lane and dropped his speed to approximately 30mph. Before every trip he made a point to check the oil and that morning was no diffetent. All oil levels were fine. After a few minutes the oil light came on. He got off at the next exit and put in around 1 quart of oil. . Still no lights but the terrible knocking noise coninured. He sat for a bit and let the new oil run through and started to make his way home at which time the engine light and the oil light came on. He then pulled over and called a tow truck and had our car towed home. Our engine is completely blown. Upon starting it makes a terrible knocking noise and after 15 to 20 seconds turns off. A mechanic checked our car over and said there was metal shavings in our oil. We have contacted kia but they we are not willing to do anything as we did not get all services and oil changes at the dealership.

13 Engine Knocking Noise problem

Failure Date: 04/11/2017

We started having problems at about 20,000 miles. The car was pulling as we tried to accelerate and smoke would blow out of the tailpipe. We took it into the dealership in which they stated we had sludge in the engine. They stated to maintain regular oil changes, but we would need a new engine. 4 months later they did an oil change and stated the oil was clear of sludge. Within 2 weeks, we heard a loud banging sound from the engine, it got louder and was barely going 5 miles/hr. We were on a major road and were able to pull into a parking lot. We had it towed to the dealership (central kia of plano). Without even looking at it, they said it was the sludge in the engine and we needed our engine replaced ($7000). They would not even look under the hood until we paid them $400 to open it up. They stated the work would not be covered under our warranty even though we are only 2 years into it and around 30,000 miles. I called kia consumer affairs (800-333-4542) and they contacted the dealership and that's when they finally opened the hood and found sludge in the engine. They took pictures and sent it to kia "tech" in which our claim was declined due to "lack of maintenance". We provided receipts for our oil changes. They did not accept 3 of them because they did not have a "po#" and they did not accept 2 of my credit card receipts. I told kia consumer affairs the 2015's are having the same issues as the recalls 2011-2014. She stated the dmv is collecting information on the 2015's. Everyone call consumer affairs!! there is an engine problem with the 2015's and kia is not standing by their warranty. We have not been provided a rental car. I have also escalated this issue to kia's "escalation dept" in which they stated to get them more receipts and "tech" can review the case again! I have gathered more receipts including how often we were putting oil in between oil changes.

14 Engine Knocking Noise problem

Failure Date: 12/11/2016

Leased a 2015 kia sorrento, in my third year of lease, regular oil changes every 3 months, heard a knocking sound in engine at approx. 35,000 miles on my way home from my son's hockey game on the highway which got louder and louder. Took it to the kia dealer and immediately the sales person informed me that it was the connector rod failure without even working on the car. Showed kia all my receipts for oil changes, waited two weeks to hear back from them, finally I called and they offered to pay for engine but I would be on the hook for 1200 on labor. Not sure why I am on the hook for labor on a faulty engine. They claimed there was sludge in the engine. Looked online and saw a recall for optima engine connecting rod for kia in which they are extending their warranty from 100,000 miles to 120,000 miles because of the same connecting rod problem. So they know they have an issue with this part but still wants me to pay for some of the cost. I don't have 1200 to pay for the repair, its now going on 3 weeks without the vehicle while they review my claim, no rental vehicle, and I am expected to pay on a lease of a vehicle I don't have. Vehicle is still in repair shop.
