A warning about Hyundai😡😡😡: I have learned that Hyundai recalled almost half of а million vehicles for phantom braking. This is exactly what I have being complaining about for a year and a half, starting one month after purchase, concerning my 2025 Hybrid Elantra. It would suddenly drop the speed to 20mph, creating extremely dangerous situations. I have been bumped off by the dealership, Hyundai America, and Hyundai Worldwide. They did not know what the problem was and blamed it on me. Now, when the cause is known and I inquired, I was told that my car is not listed for this fix. This is outrageous. Previously they could not find what was wrong. Now they know, but Elantra is not being fixed. This is a break of warranty and should be either fixed, or covered by the lemon law, as I have asked since month after the purchase. It was my family's fourth Hyundai car (mostly due to the long warranty, and they were also decent cars), but I will NEVER ever buy any of these after the way we are treated.
NHTSA complaint #11748578 — an unverified report by a vehicle owner.
Vehicle: 2022 Hyundai Elantra Hybrid Safety Complaint: While driving on the highway, my 2022 Hyundai Elantra Hybrid displayed a warning message stating “Check Hybrid System. Stop Safely.” Immediately after the warning appeared, the vehicle lost power and acceleration. The car entered a reduced-power mode, making it difficult and unsafe to maintain traffic speed. The warning instructed me to stop the vehicle immediately. This occurred while I was traveling at highway speeds, creating a dangerous situation for myself, my passengers, and other drivers. The sudden loss of power could easily result in a rear-end collision or other serious accident because the vehicle is unable to accelerate normally and traffic may not have enough time to react. My vehicle currently has approximately 69,000 miles and is within Hyundai’s hybrid system warranty period. I believe this issue represents a significant safety risk and should be investigated, as other Hyundai Elantra Hybrid owners have reported similar failures. I am requesting that this issue be reviewed due to the potential danger it poses to drivers and the public. Mileage at failure: Approximately 69,000 miles.
NHTSA complaint #11742526 — an unverified report by a vehicle owner.
The emergency braking system activated and began slowing down the car on two occasions: sometime in the fall of 2022 and on 09/01/2025. In both instances, I was driving about 65mpg on an interstate. There were no cars in front of me to cause the system to activate.
NHTSA complaint #11690278 — an unverified report by a vehicle owner.
Cluster screen was black. Lasted for 30 minutes the initial time. Happened again, lasted for 3 days before turning back on. No turn signal sound when using turn signals. No speedometer or any of the main screen shows. No blind spot indicator lights or sounds either. No engine lights or any other lights visible before this occures. Safety was absolutely at risk. Couldn't even tell the speed I was going .
NHTSA complaint #11657379 — an unverified report by a vehicle owner.
Driving on interstate at 70mph. Multiple, five or six, warnings pop up in rapid succession mostly dealing with the safety features such as distance to car in front, adaptive speed control, lane keeping. The last one was hybrid system - safely stop. The car then immediately lost all acceleration power leaving us coasting. This all happened within a few seconds. Terrifying. Luckily we had space to get over quickly. 30 miles sooner we would have been in downtown Jacksonville with no place to maneuver. Extremely dangerous. A few seconds warning then nothing. Turned the vehicle off as soon as we stopped and car was completely dead, no electrical power to anything, including flashers. Not sure how you can’t have flashers on a hybrid. Basically no warning to no power at highway speeds and then no flashers. Something is seriously wrong with this.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My Hyundai Elantra hybrid has had the horn and front radar go out 3 times. It will eventually start working again. Heavy rain or snow will disable the front radar and then it won’t go away for a while. When the front radar is out, I cannot use cruise control. It is disabled. I feel adaptive cruise control is much safer and cruise control in general. Apparently many people have similar issues. The horn not working often is also a huge concern. I am concerned I cannot rely on my car.

At around 93k miles my HECU unit apparently malfunctioned at the same time as the left front tire speed indicator. All of my safety features ABS, adaptive cruise control, lane departure, lane keeping etc do not work because of this.
NHTSA complaint #11621727 — an unverified report by a vehicle owner.
The car has an annoying picture of a coffee cup and tells me to consider taking a break followed by annoying beeps. This announcement happens every 5-10 minutes on the expressway regardless of who drives the car and if they are staying in the lanes. Hyundai took the way to disable this out of the menu this year and all the people in the car hear is annoying and distracting beeps on trips on the expressway
NHTSA complaint #11608704 — an unverified report by a vehicle owner.
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

When passing under a bridge or traveling underneath train tracks, the forward collision warning would activate causing the car to brake when no other vehicle is in front

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.

My car has done 4 false automatic emergency braking incidents while I was on the freeway (all times). There was no vehicle in front of me or the sides and my car started applying emergency brakes with a message pop up on the digital dashboard. Looks like the system is falsely detecting there is a car in close proximity. When this happened, I noticed the back car hit the brakes and immediately switch lanes. The sudden brake could cause a collision. The car allows me to take control after a couple seconds but when the warning appears I can not. I have not reproduced or verified the case with a dealer but the instant has happen 3 times in the past month. It has not been inspected by any other parties.
NHTSA complaint #11579009 — an unverified report by a vehicle owner.
Driving on a highway at 80mph, adaptive cruise control was engaged. It was a clear, sunny day, around 55 degrees F outside. We were 3.5 hours into a 4 hour drive. There were no cars in front of the vehicle. There were other cars in the lanes immediately to both the left and right of us, as well as a car behind us. The car gave a warning for Automatic Emergency Braking, although there was nothing to avoid. No vehicles were merging into us, no one was going to rear end us, and nothing was in front of us in or near our lane. The car then started braking automatically and attempting to swerve/turn automatically. I had to fight the automatic system to stay in our lane and not crash into the vehicles immediately to the left and right. This was extremely dangerous at highway speeds.
NHTSA complaint #11576726 — an unverified report by a vehicle owner.
I was driving on the Highway at the posted speed limit when the warning "Check Forward Safety System" came up and remained on my dashboard. The cruise control stopped working also. The light remained on even after stopping and starting the car and has remained on ever since. I have never been in an accident nor has my computer system reported any collision. My Hyundai Blue Link app gives me the following DTC: C162078. It started on [XXX]. My collision detection system does not appear to be working at all and my cruise control no longer works. I'm very concerned about it malfunctioning based on other entries on the nhtsa.gov website. I took the car to Hyundai Service Center and they are trying to convince me this is due to a collision and warranty will not be covering it. They tried to charge me for diagnostic even though I already had the error code on the Hyundai BlueLink App. They confirmed that my computer has zero reports of any collisions. The service tech said, and I'm quoting, "The system is very sensitive and a swift kick could cause it to malfunction." That sounds like a manufacturing defect to me. I have never been in an accident with this car, there is zero visible damage to the front bumper, and my computer has no report of an accident. The dealership urged me to contact insurance. My Major Insurance Company told me this was absurd, would never be approved, and is clearly mechanical. They also mentioned anecdotally that this problem has been coming up a lot for them with modern Hyundai models. Then I called Hyundai Corporate and they have escalated the issue, agree it sounds mechanical, and will be contacting me in 3-5 business days. They apologized profusely so I am still holding out hope for warranty coverage. I believe the dealership is trying to blame me for this mechanical failure to avoid expense on their end. I have had many software-related issues with this car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA complaint #11572957 — an unverified report by a vehicle owner.
2 times on freeway and 1 time on city streets, no vehicles within 100 yards and vehicle came to complete random stop. On freeway, tires skidded it was so abrupt and had neck pains for a few days thereafter. One time also on city street, corrective steering pulled shaply to right almost causing accident. Called hyundai and the representative had no advice or care to even intake the issue for records.not a safe vehicle especially since the engine has already failed and the ac has been replaced. It's now a frankenstein death trap being a danger to myself and others but they do not care.
