2017 Kia Cadenza Problems

The contact owns a 2017 Kia Cadenza. The contact stated that while driving at various speeds, the vehicle suddenly lost motive power. The contact waited before restarting the vehicle and continued driving. The ABS warning light was intermittently flashing. The failure became more persistent, causing the vehicle to lose power steering functionality. The power steering and traction control warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed, and it was determined that the Motor Driven Power Steering (MDPS) and Electronic Control Unit or Engine Control Unit (ECU) had failed. The parts to replace were Part Number: 56340/F60, a genuine OEM Motor Driven Power Steering (MDPS) Control Module. The vehicle was not repaired. The vehicle was not repaired. The contact stated that the vehicle was previously included in Manufacturer Recall Number: WTY039. The manufacturer was made aware of the issue, and a case was opened. The failure mileage was approximately 165,000.

Engine oil light is on and there is a burning smell when I drive. Fear of a fire breaking out in the engine when driving or parked. Had it looked at by a technician and they expressed those concerns to me and that brings me great worry. The service technician believed it was just the oil cap being loose but there was no evidence of that.

The vehicle harness is burned and under recall sc206 for HECU fuses that was allegedly repaired which should have required a check of the harness connections . part number 91223f6632 is for the wire harness during engine replacement for campaign wty039 I was told the harness was melted and needed replacing , dealer put the car back together and told me we had to wrap up the work and return rental and get my car knowing it is a fire hazard I was in contact with warranty company for escalation who would not cover the recall part according to the dealer , I am still in escalations with Kia I have been left with no vehicle .engine repair was completed via dealer ,but they have reinstalled the broken harness and told me the car is ready for pick up. I am a disabled woman with small children and do not want to burn up in a fire was advised to report to dmv and nhtsa

Multiple oil, engine/knocking issues. Drove the car unaware of loss of oil ( disguised as water from days rain) no oil light or engine light appeared. When I took to dealer the leak was fixed.Multiple times of loss of oil and only once did it show on dash.I kept taking to dealership for loud knocking and was told it wasn’t reproduced. But fixed a gasket/manifold more than once. overheating of engine when I was driving out driveway. I turned around parked and had it towed to dealership. Stated faulty sensor then was called back & told i needed to pay for the fan wires that kept the engine cool because they had melted in the process.i have had issues with right brake fluid and boot as well. Changed brakes.most of the time It has been loss of oil or engine knocking then needed to rebuild the engine which I had to pay $4000. Im sad and upset that most of the time I have had my car it has been in the shop or having to be parked for a length of time.( avg. 3-20 days) was called back to say it was another issue.Took to another dealer who repaired . had to take in for repeat engine issues and knocking sounds the wasn’t “reproduced” it was clearly heard when manager drove it but service provider said no. So frustrated that I have spend a lot of money for engine issues and haven’t had a chance to enjoy the vehicle, frustrated it is performed less than what I expected.have never taken my car to any other but dealership and kept up with maintenance. the rest was slow to accelerate(even after just picking up from dealership) a lot of knocking .Engine was “rebuilt” and It’s still in the shop today. Driving without oil loss notification.Now radiator hose is swollen/soft at top unsure if oil or water. And I need to pay for hose $400 now another $1000? braking feels unusual after they replaced. I notified KIA customer support/emailed all receipts and return call was told no recalls about a year ago and she would call dealership. Car was at dealership for a while at that time.

I have and am the original owner of a Kia Cadenza 2017 with the 3.3L Lambda engine (same engine as the Sorento lawsuit). The vehicle is currently at the dealership getting repaired due to carbon buildup causing the fuel injectors to malfunction( despite of consistently being on top of maintenance and oil changes).I have read online of lots of users with failed engines due to carbon buildup in these engines. The warning lights I got were p0171,p0174, and p0191, and am worried that after the repair the engine will eventually fail due to the buildup as the main issue isn’t properly being addressed. The issue occurred about 300 miles ago where the dealership erased it. Then told the vehicle did not have any issues. Brought it back to the Kia dealership where they finally gave a proper diagnosis after being told nothing was wrong with car. I am concerned as there are lots of owners online experiencing the same issues with their Kia cadenzas and nothing done about it. Took the vehicle in after it stalled in traffic, but, as seen, the repair cost is high and a temporary band aid.

Strong fuel odor after filling up fuel coming from the driver side, and can still be smelled inside the vehicle.

I am submitting a complaint regarding my 2017 Kia Cadenza related to an ongoing airbag system failure and Kia’s refusal to cover the repair under their existing airbag warranty extension. My VIN is included in Kia’s WTY027 warranty extension, which extends coverage for repairs related to the Airbag Warning Light illumination from 5 years/60,000 miles to 15 years/unlimited miles. Despite this, Kia Affairs has denied coverage because the diagnostic trouble codes (DTCs) pulled by the dealership do not “exactly match” the codes listed in the extension, even though the warning light is on and the issue affects the Supplemental Restraint System (SRS). Kia Affairs acknowledged the problem and escalated the case to their District Parts & Service Manager (DPSM) for possible goodwill coverage. However, goodwill is discretionary and not guaranteed, leaving me potentially responsible for expensive labor costs on a federally required safety system. My Concerns: The airbag light remains illuminated, which means the airbags may not deploy in a crash — a critical safety hazard. Kia’s decision to exclude legitimate SRS failures because the DTCs do not exactly match their list undermines the purpose of the warranty extension. Owners whose VINs are included in the extension are still being denied coverage based on technicalities, despite facing the same safety risk. Requested Action: I request that NHTSA investigate whether Kia’s narrow, code-based coverage criteria is improperly excluding safety-related airbag failures that should be repaired under the warranty extension. This appears to leave consumers unprotected from a defect in a federally regulated safety system. I can provide: The dealership’s diagnostic codes and repair order. Correspondence from Kia Affairs regarding the denial. Warranty extension documentation showing my VIN is included. Thank you for your time and attention to this matter

CAR CUPPED TIRES AROUND 17000 MILES. DEALER BLAMED ME FOR CAR NOT BEING ALIGNED AND NOT ROTATED FREQUENTLY ENOUGH I.E. 7500 MILES. I DISAGREED WITH DEALER FILED COMPLAINT WITH KIA AND THEY MADE A COMPROMISE AND I PAID FOR 2 TIRES AND KIA PAID FOR 2 TIRES, DIFFERENT TIRE BRAND THAN PREVIOUS TIRES. CAR AGAIN CUPPED TIRES AROUND 44000 MILES. I HEARD SOUND IMMEDIATELY AFTER TIRE ROTATION BACK TO FRONT. TOOK CAR TO KIA SEAN THE SERVICE MANAGER CONFIRMED FRONT TIRES WERE CUPPED. TOOK CAR TO KIA DEALER A WEEK OR SO LATER TO DIAGNOSE PROBLEM. THEY LOOKED AT CAR IT WAS WITHIN ALIGNMENT SPECS AND TIRE ROTATIONS DONE APPROX. EVERY 7500 MILES. KIA DEALER THEN TOLD ME THAT THEY BELIEVED THAT THE TIRES WERE AT FAULT AND WERE GOING TO CONTACT TIRE MANUFACTURER TO REPLACE TIRES. I STRONGLY DISAGREED WITH THIS POSITION AND SAID THAT ACCORDING TO EVERYTHING I HAVE READ AND BEEN TOLD THE MOST LIKELY CAUSE IS A SUSPENSION PROBLEM I.E. SHOCKS OR STRUTS. IT IS ALSO NOT GOOD FOR THE CAR TO BE DRIVEN WITH A SUSPENSION PROBLEM AND OR CUPPED TIRES. CUPPED TIRES ARE CAUSED BY POOR CONTACT WITH THE ROAD WHICH MAY ALSO BE DANGEROUS. I DON'T BELIEVE THE PROBLEM IS CAUSED BY THE TIRES (2 SETS TIRES DIFFERENT BRANDS) SO CAN NOT WITH A GOOD CONSCIOUS SUPPORT A TIRE WARRANTY CLAIM. I BELIEVE AND THERE IS A PROBLEM WITH THE SUSPENSION OF THIS CAR NOT SURE IF IT IS A DESIGN PROBLEM OR A PROBLEM WITH A CERTAIN SUSPENSION PART SHOCKS, STRUTS OR BOTH? ON 5/17/19 I FILLED ANOTHER COMPLAINT WITH KIA AND AM CURRENTLY WAITING ON A RESPONSE. I AM FILLING THIS COMPLAINT IN CASE OTHERS ARE HAVING THE SAME PROBLEM.
