2017 Kia Sedona Powertrain & Transmission Problems

My 2017 Kia Sedona has has regular oil changes about every 3000 miles. I was not due for an oil change quite yet and a ticking noise coming from the engine started to occur. I made an appointment at the Kia dealership right away. Just a few days before my appointment there was no warning light for the oil or engine until the engine failed, went limp and I lost power steering control, the brakes went stiff and all of the lights came on at once. It was very scary for me and my two children to lose that control of the vehicle. It can be inspected at Berlin City Kia where it currently sits and is in need of a replacement engine. After much research I have seen that this is a known issue for Kia engines and for some reason the 2017 Sedona is not included in any extended warranty's. Please investigate this. I did ask Kia for help in covering the replacement engine but was denied by the woman who I spoke to on the phone. I still put in a claim online anyway. It has been inspected by Berlin City Kia and they said there was "significant rod knocking". They are quoting me $9880 to replace the engine. After regular oil changes for the time that I have owned this vehicle and especially after I has the oil pressure sensor leak addressed as well over the last few years, it should not have died prematurely as it did. I am worried that the oil leaking so badly at that time may have pooled in the back of the engine which could have led to the rods wearing which in turn led to them knocking in the future. What else could cause this to happen? And so many other customers have complained about this exact issue. Please investigate this.

We noticed coolant leaking. We took it to a dealer and they replaced coolant control assembly/ temperature control piece. Also the O-ring that connecting to the engine was leaking. However, this is the 2nd time we are replacing the piece in 3months (not the o-ring). We did that. And spent $900 on it. As soon as we drove it 11miles home, there was oil and coolant leaking again. Took it right back. And there was fluid in the engine. Guy believes it's the head gasket. Out car isn't running. We don't know if we should replace, or junk it and have a loss of money. We are so frustrated. We have 125,000 miles. There were no warnings, no lights, just us noticing the coolant leaking, and the reservoir being full. We have pictures and have taken it to multiple mechanics and dealers.

The car stalled unexpectedly while driving on side roads and highway feeder roads. It first stalled as I approached a stop sign. The rpms quickly dropped from 2000+ to about 500. The car stalled. I put it in neutral and restarted the car. It turned over several times before restarting. After restarting and as I sat in drive at the stop sign, the car rocked back and forth as the engine pulsed. I left the stop sign and pulled into a highway feeder road. I got in traffic and slowed down. The car stalled again. Again, I restarted it in neutral. This time it re-engaged immediately. I pulled ahead in stop and go traffic where it very quickly stalled again. Again I restarted it in neutral where it took a few attempts to restart. I do have video of the tachometer and speedometer as I anticipated this happening. There are tell tale signs that it may happen soon such as sluggish acceleration, quick drop in rpms, and pulsed engine revving not a result of the drivers input. These stalls have happened 20+ times in the last year.

I PURCHASED A 2017 KIA SEDONA FROM A KIA DEALER IN QUEENS, NY, IN 2017 WITH 50 MILES. I HAD AN ENGINE MALFUNCTION AT AROUND 65,000 WHILE DRIVING ON A HIGHWAY WITH A RELATIVE AND MY CHILDREN ON NEW YEAR'S EVE 12/31/20. WHEN I INITIALLY STARTED THE CAR, I HEARD A RATTLING SOUND, WHICH I THOUGHT WAS DUE TO THE COLD WEATHER; HOWEVER, AS I DROVE OFF AND DROVE FURTHER AND APPROACHED THE HIGHWAY, THE CAR STARTED TO DECELERATE. AFTER THE CAR DECELERATED, THE CAR CUT OFF WHILE I WAS DRIVING. IN A PANIC, I STARTED THE CAR AGAIN AND PULLED OVER TO THE SIDE. I HAD TO REPEAT TURNING THE CAR ON, THE CAR SHUTTING OFF AND DECELERATING, TURNING THE CAR ON, AND DRIVING TEN MILES TO RETURN HOME. THE VERY NEXT DAY, 1/1/2021 THE CAR WAS TOWED TO THE DEALERSHIP THAT HANDLED MY LEASE BUYOUT. THE SERVICE MANAGER EXHIBITED PROFESSIONALISM AND OFFERED EXCEPTIONAL SERVICES TO ENSURE THAT I UNDERSTOOD THE REPAIR PROCESS. HE INFORMED OF CHARGES THAT WOULD BE INCURRED IF KIA DID NOT COVER THE WARRANTY. KIA WILL NOT HONOR THE WARRANTY. THE SERVICE MANAGER INDICATED THAT RECEIPTS WERE REQUIRED TO DOCUMENT OIL CHANGES PERFORMED ON THE 2017 KIA SEDONA. SERVICE RECEIPTS FROM KIA DEALERSHIPS WERE PROVIDED; HOWEVER, ADDITIONAL RECEIPTS WERE REQUIRED. I CONTACTED THE KIA CORPORATE CUSTOMER SERVICE, THE CUSTOMER SERVICES REPRESENTATIVE EXHIBITED PROFESSIONALISM AND ADVISED ME TO GET RECEIPTS OF OIL PURCHASES FOR ANY OIL CHANGES DONE OUTSIDE OF A SERVICE SHOP. DUE TO LIMITATIONS IN RETRIEVING RECEIPTS WITHIN A CERTAIN TIMEFRAME, I AM UNABLE TO PRODUCE ADDITIONAL RECEIPTS. I AM WITHOUT MY CAR FOR ONE AND A HALF MONTHS, I AM RENTING A CAR WHILE PAYING MY MONTHLY FINANCE BILL, AND KIA WILL NOT HONOR MY WARRANTY BECAUSE OF A LACK OF RECEIPTS OF OIL CHANGES, ALTHOUGH THE CAR WAS PREVIOUSLY CAR SERVICED IN NOVEMBER 2020 AT A KIA DEALERSHIP.
