Forward collision Avoidance assist system - warning comes on, was told the hydraulic electrical control unit failing, this may need a recall.
Under normal operating conditions all sensors malfunctioned causing all abs systems to stop working.
The contact owns a 2019 Kia Optima. The contact stated that while driving at an undisclosed speed, the oil pressure warning light illuminated. The contact stated that shortly afterwards, the check engine warning light illuminated, and the vehicle started losing motive power while attempting to accelerate. The contact stated that the vehicle was shuddering and jerking while driving. The contact also stated that the Forward Collision Avoidance sensors activated inadvertently while driving or the vehicle was parked. The vehicle was taken to a local dealer where it was diagnosed with excessive oil consumption and the contact was advised that the failure with the Forward Collision Avoidance sensors was the regular function of the vehicle. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 57,813.
The engine is consuming oil very fast and needing oil way before the next oil change. The oil consumption test Kia did stated that it was 2 quarts low after the first 1000 miles. Car does not have extended warranty but this a manufacturing defect. Suggestion was new motor. Also it's recall for the forward collision safety feature but my car vin is not included even though it goes off when nothing is in front of me. They want me to pay for these issues the motor cost the same as the payoff of car. This is ridiculous, I purchased Kia due to having a older model that almost got 300,000 miles on it before transmission died. I got a great payment and a newer car but didn't expect to have this motor issue or safety problem with no help from manufacturer. I'm stuck keeping oil in car so it's burn out & cutting safety feature off so it stops breaking when nothing is in front me. Both of these issues or manufacturing defects and should be fixed by KIA.
My 2019 KIA optima with 116,021 odometer on mileage. Stop in the middle of High Volume Traffic , Because of Software Issues , I suspect . All Forward Collision Warning Detection , Also Rear Collision Warning Alerted on dashboard!!! Which Causes my Car to stop in the middle of Traffic Completely shut down. I was able to get my vehicle towed to KIA West Dealership Located in lithia Springs GA . I requested a diagnostic test and was informed by my service advisor and service manager that my vehicle has a burned out wire located in the left right rear sensors radar assembly, bumper area . Which will eventually have caused a fire or actually already did, I asked how did it happen? I was told it just simply burnt out. !!!! I was told the assembly box junction box needed to be replaced, which I agreed at that moment in order to diagnose the vehicle. Second the electrical problem was revealed, which is the big problem now currently for 1 , the vehicle is not safe for a midsize sedan on public roads and highways the if this make and model car causes random fires. secondly the parts very expensive and suspicious. I’m currently still doing my investigation. Unfortunately I had to agree for the sensors to be replaced and fixed because personal reasons I need my vehicle to get back-and-forth to work, etc.. I’ve been in contact consumer regional services, No one is able to find a recall with my Vin number the car never been in a accident ever. I have a picture of the hazardous burned out wire the technician showed me as well. As they claimed randomly caught fire.
I like kids however I purchased a Kia used in 2021, I started to notice that all consumption was going out fast before oil changes was due. I still have this ongoing problem but they say there's no recall on these GDI motors however other people I see informs or experiencing the same issues. I now have to try to get an appointment with Kia for an oil change before it's time for the oil change and to do a oil consumption test and then hopefully the main factors or kia will replace this motor even though there's no warranty on the car. I might also have a issue with the front collision feature because I have been noticing in the past few weeks that this feature comes on even when there's no car in front of me it will start to break however it says that my car is not a part of a software upgrade so I got to ask them about that as well. There is definitely a issue with the GDI motors and Kia really needs to recall them all and replace the motors it should not burn all the way that it does I've never had any car of any brand or manufacturer burn oil the way that this car is burning oil. I cannot financially afford to go out here and trade this car in and get another car with the type of payment that I have for this car since I had my bank finances car.
I was doing 65 on the hwy when Forward collision started so sound off and slowing down car when there was no other car around me this happened on several occasions
On March 2022 Forward Collision Warning System, Blind Spot Warning System, ABS braking System and other systems associated with a bad passenger rear wheel sensor not working. On March 17, 2022 rear passenger wheel sensor repaired under warranty by local Kia Dealer. In September 2023 same issue with the above warning systems occurs with only another 2,000 miles on car after previous repair. Local Kia dealer states both rear wheel sensors need to be replaced. Kia dealer states vehicle is no longer under warranty and will cost in excess of $800 to repair. After checking similar complaints online, I believe there is an inherit defect with this type of vehicle's wheel sensors and a recall is needed to enforce Kia to stand by their product and ensure the safety of the vehicle and their customers.
I was driving and tried to brake but my car did not stop and ended up hitting guardrail. A couple weeks later I was driving and there was nothing in front of me but the car abruptly stopped in the middle of road
The second month after I purchased this vehicle the master warning light and forward collision light popped up and car vehicle started de-accelerating in the middle of the freeway and I had to pull over and then the car died. Repeatedly took my vehicle to the Kia dealership and no one still has been able to help me. They claim no one at their corp. Office in California what that means so it has been going off ever since and I don't want my vehicle to died again. PLEASE HELP!!!
Breaks locked or failed and was forced off road into a ditch, car totalled
Car stopped suddenly and now the car doesn’t start.
The contact owns a 2019 Kia Optima. The contact stated that while her son was driving at an undisclosed speed, the Forward Collision Avoidance system inadvertently activated, prompting the vehicle to inadvertently stop. The contact stated that there was no other vehicles or objects nearby during the failure. The vehicle was taken to the dealer, who advised the contact that an unknown obstruction on the Forward Collision Avoidance sensor had possibly caused the inadvertent activation. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 54,000.
Forward collision warning failed to assist resulting in a collision that is considered a total loss.
As i attempted to start my vehicle, it continuously made a clicking noise until i finally hit the gas and made it crank up. About halfway through my work commute, the forward collision warning came on with no visible forward threat on the road. All of a sudden the car slammed on its brakes without me even touching the break and continued to do so anytime I put my foot on the gas above 50mph. I tried to turn it off when I parked the car but it still acted like there was something in front of my car.
On October 11,2022 I was involved in a vehicle collision that resulted in damages to the front of my vehicle and the rear of another. My two children and I suffered injuries that we were not able to recover fully from. The driver of the other vehicle was uninsured and has not been accessible!
The contact owns a 2019 Kia Optima. The contact stated upon starting the vehicle, the Forward Collision Avoidance warning light was illuminated. The vehicle was taken to an independent mechanic, who could not duplicate the failure. The dealer was notified of the failure and informed the contact that the vehicle could not be repaired under the federal safety agency Campaign Number: 19V539000 (Forward Collision Avoidance) since the VIN was not included. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the dealer. The failure mileage was approximately 99,000.
To begin, there was a recall on the forward avoidance collision system. The fix was to have the system reset at the dealership. Almost like a system update. I had that done after multiple lights appeared on my dash. 5 months later, the lights would illuminate again periodically, but turn off after a few minutes of driving. Two months ago, the lights came on when I was traveling on our highway at about 45 MPH. There was no cars in front of me, nor any objects. The automatic brake applied itself as I was turning off of this major highway. I hit the gas to try to turn off of the highway after the brake was applied, and my car wouldn’t accelerate. Since then, the light has stayed on every time I turn my car on, and for the remainder of the time I’m driving it. The brake has also self engaged itself twice since then. It’s a huge safety risk as someone could hit me from behind. The system update obviously didn’t fix the issues. The Kia dealership in my area, Tameron Kia, said that there was nothing they could do for me since they did the computer update. She was certain that it was a different issue, but it isn’t. My car has 60,000 miles on it and have been dealing with this specific issue since 3 months after I purchased the car. It’s not safe for my children and I, and something has got to be done about the issue.
ABS light came on for no apparent reason and took car to Kia dealership and was told it needs ABS Issue: “Your car is going to need an ABS Actuator, this controls how the ABS modulates the brakes when under dangerous braking conditions so that your brakes don't lock up..$2676.56 just for that repair if you'd like us to replace it” and I searched online and do see that some 2019 Kia models had a recall for this very issue, but my VIN is not showing up as affected. The lights came on about 6 mos ago, cleared and then came back on again. Car is at Moritz KIa in FW, TX right now.
The contact owns a 2019 Kia Optima. The contact stated while driving approximately 70 MPH, there were knocking sounds before the engine suffered a failure. There were no warning lights illuminated. The contact pulled over safely and the vehicle was towed to a local dealer. The vehicle was diagnosed with an Electronic Stability Control (ESC) unit software not being updated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 62,000.
The forward collision system failed in my Kia 2019 optima. I was driving and the lights come on the forward collision lights and the engine turned off I had no control over the vehicle I couldn't even turn the wheel. It turned right on its own and threw me up on a bank and I rolled twice. The car was out of control. I've never been so terrified in my life. The safety measure failed and nearly cost my life. My brakes locked up as well and I'm lucky to be alive. This was uncontrollable the car was in control and it was wrong. I'm not sure if it was the forward Collison or the traction control and there were no warning lights ever on this was a new vehicle. I have witnesses that seen it someone pulled me out the vehicle bc my doors were locked. The car is currently deemed a total loss by state farm and is in Pulaski at IAA #5409946490. Stock # 31768854. Please help me get this out for other Kia owners the safety issues life or death. There was a police report and I do have pictures. I have reached out to Kia many times and they will not help me or inspect it. I'm at a loss of what to do. Please help me Kia has confirmed safety issues with this model and year with the forward collision error. Although I didn't know this until after the accident and I researched it.
My daughter hit a deer at 65 mph causing total loss 5 miles prior to the accident the forward collision warning light came on stating it was inactive due to the sensor being blocked or damaged.
I just think theres some sort of a tech issue with my electronic dashboard. My passenger seatbelt sign goes on and beeps incessantly when there is no passenger in the seat. My caution alert button comes on saying I have low tire pressure when it’s only one number less than all the other tires. My oil change reminder never comes on. Today I was driving normally and the car in front of me barely tapped their breaks (and I was not close to them at all) and the collision alert started beeping. My car randomly gets cold and the AC smells like it’s on, but it’s not (the button isn't lit nor did I turn it on) It normally doesn’t allow me to turn the outside air button on/off. Like in the winter when it’s freezing outside and I wasn’t to press the button to only circulate the inside air in the car, it doesn’t allow me and I have to freeze and be uncomfortable in my own car.
Out of no where the Front Collision Avoidance Assist came on while driving as well as the automatic emergency braking sensor came on I had my kids in the car no accident or anything
Tl* the contact owned a 2019 kia optima. The contact stated that while upon making a left turn at 20 MPH, the automatic emergency braking system independently activated and abruptly stopped without warning. Due to the failure, the vehicle behind him hit him from behind which pushed his vehicle into a 270 degree angle. The contact stated that the passenger side airbags deployed; however, his driver side airbags did not. The contact stated that he had hit his head on the driver side visor; however, he did not seek medical attention for the injury. A police report was filed at the scene. The vehicle was totaled as a result of the accident and was towed to his insurance company's collision center. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had been destroyed. The failure mileage was approximately less than 200. The VIN was not available.
Last night a warning message popped up that said there was an issue with the front crash collision sensor and it was turning off. The warning lights stayed on while driving home and this morning it was off but popped back up after around 15 minutes of driving.
Was driving on I 95 when the vehicle pulled me into the median totaling my car. I was unable to apply brakes and unable to turn my steering wheel in the other direction to avoid the collision.
I was driving on 8/28/2020 and a warning light came across the dashboard that read my forward collision camera was not working and it stayed lit for about 3 minutes while driving and eventually went off before I parked the car. I am afraid to drive the car if the braes may fail.the vehicle was in motion initially approaching a stop light when the message came across the dashboard. I was on a city street driving.
Was driving on a city road and a car stopped in front of us (while only going 25mph) then the caution front sensor lights came on. The car had a notification that popped up said front camera is blocked. Stayed on for 5 minutes then just shut off.
