Engine Failure due to rod and bearing failure
I am the original owner of a 2016 Kia Sedona, purchased new from the DeMontrond Kia dealership in Houston, Texas, in August 2016. The vehicle currently has 63,400 miles and has been maintained according to standard schedules. Two weeks ago, I noticed a slight knocking sound and took the car to the dealership for an inspection. I was informed that there is sludge buildup in the engine and was told the repair would not be covered under warranty due to alleged owner neglect. The dealership quoted $10,000 for an engine replacement. Prior to this, there were no warning lights or indicators of any issues, and there have been no oil leaks. I have retained most of the records and receipts for the oil changes performed on the vehicle.
Oil leak caused engine to fail.
Since the day a bought the car I have had to constantly deal with oil leaks and burning up oil. We had to check the vehicle every Sunday for oil replacement. The vehicle on one day just stopped in the middle of the street. It had a complete engine failure. I had to pay thousands of dollars. I contacted Kia with out help. They claim my vehicle was not part of their class action settlement of engine failure. And I can’t sell the car because all mechanics know the engine is trash and the vehicle is worth nothing. And Kia won’t help at all.
My family and I were all driving in the car. We were at a stoplight, and fully stopped as it was a red light. All of a sudden, we heard a weird noise, and all of the dash lights on our car appeared, and then the car fully turned off. We could not get the car back on, and it would not start. Prior to this, it was driving totally fine, and we had no lights on our dashboard indicating something was wrong. Just stopped out of nowhere. If we were on the freeway, and our car just immediately turned off, we could have been in a major, life-threatening accident. After 2-3 times of trying to restart the car, we were able to turn it on, and at least get it into neutral so we could move it off the side of the road. We were able to get it towed to a Kia dealership in which they diagnosed it as engine failure and said we would need to replace the whole engine. This car is around 10 years old and has less than 130,000 miles. It has been meticulously maintained according to Kia standards, and there should be no reason that a well maintained car should need a new engine at this point. We had frequent oil changes, and even had an oil leak that we had to repair just a couple months ago.
2016 Kia Sedona SX-L (VIN: [XXX]) equipped with 3.3L Lambda II GDI engine. This is the second engine failure — first engine failed due to head bolt studs separating from the block, second (mechanic sourced) engine began heavy smoking and nearly caught fire due to possible oil starvation/rod bearing failure. Vehicle is parked and unsafe to operate. Temperature gauge at time of incident was going towards above average operating temperature. This is the exact defect covered under multiple NHTSA investigations into Lambda 3.3L engine seizing/fire hazard (including PE23-019 for similar Kia Sorento models with the same engine, and defect petition DP24-002 specifically for 2016 Kia Sedona). Kia has extended the warranty on these engines to 15 years/150,000 miles for bearing damage in some cases, but no full recall exists yet. Requesting immediate investigation and inclusion in an engine fire recall similar to those for Theta engines. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Engine started knocking loosing power just like our 4cylinder GDI engine. These engines are also not safe to be operating
With a 140000 miles and the timing chain and component already failing my mechanic told it could die anytime soon local or on the highway
The Sedona just stopped in traffic with out warning with my kids in the van. No type or warning lights came on. I had recently got an oil change and tune up. I almost caused an accident. It was extremely scary. I am thankful no one was hurt. I had to pay for a tow and come to find out the engine is locked . The machine started it had very low oil. Which makes no sense since it hadn’t even been 7 days since my oil was changed .
I was driving down the highway and the engine light came on. The car suddenly wouldn't accelerate or go above 1500 rpm. There was also a rattle noise. I limped home and checked the oil. It was bone dry. I get regular oil changes every 3,000 to 5,000 miles. The car burned oil way too fast and gave no warnings that the oil was low and there was no leaking. I'm unsure of the extent of the damage. I'm adding oil and taking it to a mechanic for inspection. I fear I may need a new engine.
Engine randomly began burning oil at an incredible rate (I checked it approximately 500 miles ago and it within appropriate levels) and resulted in damaging the engine. No “low oil pressure” light was activated, and upon starting the vehicle one day it developed a terrible cylinder knock. I checked the oil dipstick, and was completely dry, there was absolutely no oil on the check stick. I also checked and confirmed that there was no leak that caused the oil to drain.
Van completely locked up on me. Oil dipstick no oil, seems this is an issue and a Kia problem. Seems I need a new engine. Regular oil changes with no issues prior to this happening to me.
Complete engine failure while driving with 4 passengers along freeway. Engine began to have a knocking noise, with no warning lights. Engine failed a few miles down the road, and started a small fire in the engine bay. Vehicle is currently under inspection at the dealership. Mileage at the time of incident was about 98,200.
Engine overheating and check engine light went on. Vehicle would not start after shutting down.
I was driving in normal operating conditions, with no traffic when suddenly the engine seized. After contacting a towing company to get my vehicle home, I started checking for anything I could find and noticed that it had zero oil and no visual signs of a leak anywhere. There were never any warning lights or sounds until it abruptly stopped. I have not had it looked at by anyone other than myself and a neighbor whom is a mechanic.
My 2016 Sedona’s engine is not operational. At this moment it is sitting at the dealership after having a diagnostic completed in which I was informed that it will cost me $21,000+ to replace my engine. I am SHOCKED to be informed of this! I love my car! It is our family car full of precious memories! There were no warnings that something was wrong with my engine. Not a single one came on - believe me I would have taken a picture of it to inform the mechanic for it to be serviced. I have had it serviced repeatedly for oil changes; more oil changes than what should be done for the age and milage according to the manual. It is not due to my lack of competence and poor maintenance. I've done my part. Now to find out that I can't drive it. Now to find out that I don't have anything reliable to get my children to school, is unacceptable! This is a major issue that should be covered by Kia, not out of my own pocket. The engine and its ability to function properly is your responsibility as a company. Engine problems with this model have been noted by others, and resolved. Please resolve this issue as soon as possible. I look forward to hearing from you.
Engine Failure
Timing Chain Failure/Cam Shaft Failure/Bank 2 Failure/drastic loss of engine oil. Got home before engine seized, could have crashed if engine failed on freeway. Codes confirmed techs suspicion. No warning lights or notifications appeared on dashboard.
I was at an intersection & was turning left. In the middle of the turn the car started knocking noise and vibrating and turned off in the middle of the intersection. It did not crank for several tries while I was panicking with a car full of kids in a busy intersection. When I got it to crank again it turned off again. Some good Samaritans then helped by holding traffic and pushing us out of harms way in a church parking lot. I kept trying to crank it and when it did, I tried to put it in drive and it started the violent knocking and vibrating like it was going to blow up. I had it towed later when I had gotten paid. I had it towed to Keffer Kia where they told me total engine failure at 88,000 miles. I still pay $300 monthly for the car and have 5 kids that I have to shuffle in my mother in laws 4 door car.
