Driver Assist & Collision Avoidance complaints by model year
2020 Kia Forte, 2.0L 14F engine, 109,000 miles: On July 3.2026 "check engine" light came on. Drove to local auto parts store to have code downloaded, P0017 cam position sensor. Car was performing fine, except for engine light. Drove car to Kia dealership. While driving, warning light for "front collision system came on and car began performing erratically. Left car at dealership for diagnostics. Yesterday received call from dealer, stating that engine needed total replacement due to "lack of oil". Quoted repair cost estimated at approximately $8,000. Car has been regularly serviced, including oil and filter changes per handbook. I have all records for the services. The were no indications of low oil pressure or engine overheating, no warning lights, all gauge readings displayed normal ranges. This same car had a failed transmission replaced approximately 2 years ago, which was covered by an extended warranty related to a recall. There have been 2 engine failure recalls as a result of 2 class action lawsuits for Kia cars with this same engine failure up through the 2019 model years, providing new engines and/or extended warrantees, however, this does not applicable to 2020 and newer models, even though it's the same exact same engine model with the exact issue causing the failure. Engine failure in traffic condions can obviously lead to immediate safety issues. I currently have a call into the Kia customer service/complaint department, but no resolution offerred to date.
NHTSA complaint #11749072 — an unverified report by a vehicle owner.
While driving, the Forward Collision Warning system activated unexpectedly without any apparent hazard or obstruction in front of my vehicle. Immediately after the warning appeared, the vehicle suddenly lost speed and became very slow to accelerate. I was unable to safely increase my speed while traveling on a busy roadway, creating a dangerous situation and nearly resulting in a collision with surrounding traffic. Due to the sudden loss of power and inability to accelerate normally, I activated my hazard lights and was forced to pull onto the shoulder of the road for my safety and the safety of other drivers. There were no visible obstacles, vehicles, or road conditions that appeared to justify the activation of the Forward Collision Warning system. This unexpected activation and resulting loss of vehicle performance created a significant safety risk. I am submitting this complaint because a malfunction of the Forward Collision Warning system or related vehicle systems could potentially lead to a serious accident or injury. I have experienced recurring brake issues despite recently having the brakes replaced. The problem continues to occur, raising concerns that there may be an underlying electrical or electronic malfunction affecting vehicle performance. I was recently pulled over shortly after the brake replacement due to concerns regarding the vehicle's braking system. Because the issue persists after repairs, I am concerned about the safety of the vehicle and the potential risk of a crash or loss of control.

February 1st 2026, I done my oil change. My car was running fine. No check engine light was on or anything, my forward collision warning started disabling itself when I always kept it on. When I try to accelerate my vehicle it would take a while to accelerate. March 7th 2026, while I was driving, my car quit while it was still running. It also quit the same day again just in park. March 8th 2026, I went to take my vehicle to get a diagnostics and when leaving my home. My car stalled out and quit while in drive. After taking my vehicle to the mechanic, the mechanic reported to me my car had no oil in my car and my motor was fried. I have had the vehicle less than a year and it’s giving me all of these issues

NHTSA complaint #11699296 — an unverified report by a vehicle owner.
Electrical issues since 44K miles I’m at 50 K miles. I’ve complained multiple times and they kept saying electrician wasn’t available. Then they lie about it being a waitlist for a loaner car. All the lights on the dashboard goes on and all the dealership couldn’t diagnose the problem. The second time the check engine lights went out the back up camera. They said it was the back up camera the backup camera was replaced the backup camera now messes up all the time and does not cut on when backing up randomly cut on when driving Kia issue was flashing lights, but they decided to worry about the check engine light, which was the careless converter, they fixed the careless converter And didn’t fix the flashing lights problem. They tried to say the car electrical reason was physical damage, which was false and now the electrical problems are getting worse the gear shifter license to work on the PRND the right brake light in the front and back goes in and out. I don’t know what the mileage is while driving I got a ticket from the cops because of that, the mileage randomly changes and I never know how much gas is in the car when I put in gas.
NHTSA complaint #11691550 — an unverified report by a vehicle owner.
The lane assist malfunction and periodically jerks. Very unsafe I no longer use this feature . To keep control of the vehicle. I never got it inspected. As the lane assist was in use and it would jerk it would alert me of a lane departure . I mention this to include every known problem I have experienced with the vehicle. The problem That brought me here. Is my engine light came on today. Leading up to this. I have had oil leaks since I've owned the car. Im adding oil in between oil changes due to it being low. In the beginning it was a hint of smell of gas in the oil. I was informed to do more frequent oil changes. Over time the smell of gas grew stronger . No Indication to a problem then. Now the smell of gas is prominent in the oil. When the dip stick is checked its always needing more oil and smells of gas and has blackness like burning in the oil. Now there's a check engine light on. And everything I looked up says to discontinue driving the car. I am having a mechanic look at it with a code reader.

NHTSA complaint #11684783 — an unverified report by a vehicle owner.
The front radar FCA/SCC is misdetecting vehicles in other lanes and often slams on the brakes for no reason. Other times it lights on the dash and says the system (radar detection) is off or is blocked, when it clearly is not. Kia had this same issue with the 2020, 2021, and 2022 Kia Telluride and issued TSB SC243 (with a software update). I have been to 2 different dealerships, and one had a bunch of excuses and the other dealership had no idea what i was talking about. The car was about 21 months old and millage 20,000 miles when the issue began.

Sterling wheel begins to shake at high speed and a lower speed causing the whole steering wheel to shake and make noise. And have realized the cruise control is no longer working
NHTSA complaint #11638537 — an unverified report by a vehicle owner.
Back-up camera does not function. I'm told the camera unit itself is at fault, not the electrical circuit leading to the 'head unit' (infotainment system). It has not operated property for about two years. I've owned the vehicle for7 years.
NHTSA complaint #11638568 — an unverified report by a vehicle owner.
Recently I purchased a 2023 Kia Forte on 11/09/2024 with only 53,848 miles on the odometer. Within a month the car has lost total power four times. The Advanced Driver Assistance Systems keeps faulting and kicks in taking drive control of the vehicle making it challenging to control. The current miles on the vehicle is 58,281. When I called in to have the vehicle serviced through a Kia dealership, they indicated the earliest date to bring it in is on 01/23/24, I am on the schedule for 7 am. I also contacted Kia Corporate office today 01/07/24 to inform them of the issue being that it is still under the manufacture warranty up till 60,000 after filing a complaint with them I began researching the vehicle on Google which led me here to NHTSA website there are numerous complaints that have had similar issues. This is a major problem as it puts my life in grave danger as well as others if this should occur while in traffic. The car loosing all power could cause a major accident. The Advanced Driver Assistance Systems kicking in without warning or cause takes away the ability to control the vehicle this could also cause a major accident. Why are these vehicles still being sold with these kinds of safety issues that could cause loss of life if an accident was to occure. Clearly this is a poorly manufactured vehicle and there needs to be a recall or some recourse for the consumers who have been sold these death traps. I have only acquired 4,433 miles on this vehicle since purchasing it on 11/09/24, and I should not be worrying about these kind of safety concern. Please advise
