2023 Hyundai Elantra Hybrid: false forward collision warnings

Filed Aug 8, 2024 · Driver assistance · FL

Since 2/2/24 13 episodes of all safety features failing including blind spot monitor, lane keep assist, forward collision warning, and others. Last occurrence on 8-8-24. On one occasion the car failed to accelerate in the middle of an intersection, the car did move slowly and operation returned to normal after turning off the car and pressing the 12V reset button. Diagnostic codes found on car APP include both C164286 and C164202 for all 13 episodes. Despite being told this code is "for the speed sensor because it saw a voltage drop from the battery system" the dealer claims there is nothing they can do because they can't recreate the problem. This is highly dangerous to my family and others as the safety features can prevent accidents. The most concerning is the car suddenly losing acceleration as this could potential happen where there is no safe way to get off the road in time prior to an accident. This loss of acceleration has been reported by many other people on the Facebook group I am a part of called Hyundai Elantra Hybrid Owners. The loss of safety features occurred after all recalls were performed as of 8-8-24

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Ans: The Forward Collision Warning didn't detect any vehicle ahead of me at the time of collision which caused the crash. 2. How was your safety or the safety of others put at risk? Ans: Me and my co passenger were luckily not injured but got almost killed during the collision. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Ans: The dealership or the Hyundai Motor America couldn't replicate this issue. They didn't answer the question to why the detection didnt happen during the crash and why my Automatic Emergency Braking failed. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Ans: Yes, Hyundai Motor America had a 3rd party company named Bosch inspect the vehicle to check for any fault during the time of cash. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Ans: No there was no warning signs displayed during the time of collision and no signs after the collision as well. Funny part after the collision my front bumper came off, my headlights broke, and many other components were damaged like my air conditioning and my seat heater and stuff but none of those issues showed in my blue link report(a report that shows any signs of warnings or crash detection's) that came to me the next business day in my email from Hyundai.

On December 24 2023, the vehicle's forward collision warning failed. My son has a learner's permit. He was driving the car under my supervision. He pulled into a parking lot and hit a light post. We did not receive a warning, nor did the automobile automatically apply the brakes to avert the collision. There were no injuries. There was no property damage, except for our vehicle. I did not notify the police. In retrospect, we never hear alarms or warning when pulling into our narrow garage. Our other vehicles with the same safety feature do offer an alert in that context. I think the forward collision warning system is defective on this Hyundai Elantra. I have filed an insurance claim and notified the dealership by email. Next steps are pending after we hear back from our auto insurance claims adjuster.

There are have been three significant safety issues with the car. 1. The forward collision alert system goes off without warning and with zero debris or cars in front of me. This has happened three times, putting my safety and those around me at risk. 2. The car has suddenly had what feels like the rear brakes locking up without warning midway through a turn. The car wheels were still spinning but the car stopped moving. This put me directly in harm's way. 3. While my foot was OFF the accelerator while I was approaching a stoplight, the car suddenly accelerated and lunged forward, nearly causing me to hit the car in front of me. I have taken the car in three times and called the dealership about this one more time and have had no resolution; they claim to be unable to replicate the issue. There were no warning messages prior to the failures.
