2022 HYUNDAI ELANTRA Forward Collision Avoidance Problems

I am reporting a safety-related defect involving the vehicle’s infotainment and forward safety systems. When this occurs, the vehicle also shows a “Check Forward Safety System” warning message. Diagnostic trouble code C162078 is triggered, indicating a front radar out of alignment. As a result, critical safety features such as Forward Collision-Avoidance Assist, Smart Cruise Control, and other radar-based driver assistance systems are disabled. This issue creates a significant safety risk because the driver is not alerted to potential forward collisions and cannot rely on active safety systems. The blank infotainment screen also prevents access to vehicle settings, warnings, and camera functions. In South Korea, this same defect has resulted in an official recall and free front radar replacement and calibration. However, in the United States, customers are not covered under a recall and are required to pay out of pocket for radar realignment or replacement, even though the issue is identical and a lot of time the issue came back 3 months later and customer have to pay out of pocket once again to fix the same issue. Many owners report receiving official recall notices in other markets, while U.S. owners must independently diagnose the issue. Dealers often state that the problem may be caused by radar misalignment after a software update or system fault. In some cases, cleaning or recalibration temporarily resolves the issue, but in other cases, full radar replacement is required. This inconsistent treatment places U.S. consumers at a financial disadvantage and allows a known safety defect to remain unresolved. I am requesting that NHTSA investigate this defect and require the manufacturer to issue a U.S. recall with free repair, calibration, or replacement, consistent with actions already taken in other countries.

My vehicle experienced a sudden and complete brake assist failure, including the emergency brake. I was unable to stop the vehicle, which directly resulted in a collision. Prior to the crash, the car showed no warning lights. After the accident, I had the vehicle inspected at the Hyundai dealership. The dealership stated they could not reproduce the failure and “found no issues,” which contradicts the symptoms. Since the crash, I discovered two Hyundai Technical Service Bulletins that directly match the failure I experienced: TSB 23-01-036H-1 (Relates to HECU/Electronic Parking Brake failure) TSB addressing DTC C1620 (Relates to FCA Sensor/Automatic Braking malfunction) These TSBs relate to brake assist malfunction, emergency brake concerns, and similar stopping failures. The dealership did not disclose these TSBs, did not apply the corrective procedures, and cleared the car as having “no defects.” The dealership wrote “could not reproduce concern” and “no problems found,” despite the vehicle having just been in a brake-failure crash. This brake failure created a major safety risk with potential for severe injury or fatality. I am reporting this because the defect appears unresolved, the dealership denied it, and the TSBs show Hyundai is aware of brake-related issues. I request that NHTSA investigate this brake-system failure as part of a potential manufacturer safety defect. The vehicle is currently secured at the dealership (Lithia Hyundai, Las Vegas) and is available for inspection upon request by NHTSA investigators.

The car now shows a warning "Check Forward Safety System" and cruise control, understandably does not work. I have not had any collisions or accidents for this to occur. There seems to be no recall from Hyundai, however, this appears to be a safety issue that needs to be addressed by Hyundai.

Every time I try to use the cruise button I get an error message.

For the past 2 years my Forward Safety System light on has been on in my car. It has turned off and back on repeatedly but has now been on for about 6 months. Hyundai dealerships are estimated a week or two of labor to fix which is extremely expensive for rental cars and outlandish that I bought this brand new and it is already giving me issues. No damage has been had to the car in any way.

On June 13 2023, I received an alert on my dashboard that my cruise control was unable to be used due to an issue with the front sensor. The alert went away soon after but then reappeared on August 27th, 2023 the error appeared again. Specifically error code C162078. I wasn't able to get the issue repaired until November 2023, which is also where they replaced my faulty backup camera.

While traveling on a bridge with a very steep incline, the forward safety system light came on, which disabled the cruise control. We could not resolve the warning light issue, despite taking it thru a car wash, hoping that the sensor was just dirty. The warning light remained on for several days, then went away. One month later, on a sunny, dry day, the light returned. I made an appt at the local dealership, where the car was purchased and they told me that the front sensor was out of alignment and I most likely hit something, which I did not. $370 for the alignment and since they assumed I hit something, it voided the warranty.

While driving highway speeds (65mph-75mph) the emergency braking system randomly activated causing my car to slow to almost a halt and swerve itself in the middle of the highway almost causing multiple accidents. It has happened 2-3 times over the past 2-3 months. Brought to a dealer and it could not be "duplicated" so I was sent on my way worried about this car.

Check foward safety feature dashlight came on while driving, my blue link app told me the DTC c162078 chassis alignment failed front radar On Jun 4th 2024 while in park and idle my steering wheel kept going side to side, I recorded it not sure if that had something to do with this happening on July 2, 2024 and my safety is in jeopardy I feel due to the forward collision not working, smart cruise control not working, made appointment at hyundai dealership and I showed them the code bluelink told me to show them and they said they have to diagnose car themselves and the cost would be $169.99. I had to call hyundai customer care and get a claim number because dealership said they had to charge me. Two days i waited for dealership to call me the lady stated to let dealership know to waive diagnostic fee, I was told they would waive fee but I would need to pay $497 for part and $500 for labor which includes labor and recalibration, I told them I am financing a car I don't have safety features for, so I believe this should be listed as a recall or it should be fixed free of charge, being this is no fault of my own. No accident, didn't hit anything , I was driving at night and smooth roads. Dealership wanted me to lie to my insurance company and say I hit pothole. I told her no because that would be a lie.

My 2022 Hyundai Elantra SEL's rear parking camera, rear cross traffic warning and Forward colliion warning systems have stopped working a couple of days back. I have checked online for any resolution, and it appears I am not the only one facing these issues. There are a good number of drivers who have reported similar issues. Hyundai has not issued an recall/fix for these issues and the dealer is unable to tell me if the issue is covered under warranty (I have about 45k miles on my car), unless I pay $220 per issue to diagnose first. That will get me to near $660 before I know anything about how to fix it. I would appreciate if you can please investigate these issues in 2022 Elantra SEL.

All safety features randomly appear and go off as well as while driving 80mph down the highway the speedometer and RPM gauge both dropped to zero. Vehicle has been at the shop multiple times and stayed for three months where they could not duplicate the issues. I have pictures and videos of multiple instances. Dealership replaced back up camera and was told that was the cause for the safety lights going off and within a week of getting vehicle back the forward collision light has come on two different occasions when no vehicle is around as well as two instances when a vehicle slammed on brakes in front of me and the front collision sensor did not go off at all.

I was driving on the highway three days ago, and the forward safety went off. It was raining heavily, this happened to me once before and as soon as the rain cleared, it went away. This time it has not gone away. The safety remains disabled. I am unable to locate the sensors to see if maybe there’s mud or some thing blocking it.

Automatic emergency braking appears to be getting falsely triggered. This happens when I am pulling out of parking spaces, even with nothing besides or behind me. This also happens when cars in lanes beside me pass me.

The contact owns a 2022 Hyundai Elantra. The contact stated that on two separate occasions, while driving with cruise control activated, the vehicle came to an abrupt stop. There was no warning light illuminated. After each failure, the vehicle was taken to the dealer to be diagnosed; however, no fault was found with the vehicle. The manufacturer was notified of the failure and the contact was provided a case number. The vehicle was not repaired. The failure mileage was 5,500.

Mileage: 5,500

On 2/26/2022, while driving East bound 134 at night. AEB of my 2022 Elantra kicked in. The first time AEB kicked in hard and I lost control of the car for a split moment. The warning sounds as the AEB activated and I swerved slightly (within my lane). This happened while I still had sufficient safety distance with the car in front of me and before the car in front of me began braking. The second time this happened was 10 minutes later, when there were no cars next to, behind, or in front of me. Same thing happened where AEB suddenly activated under normal driving condition. The vehicle is available for inspection upon request. This sudden braking puts me, my passenger, and car(s) behind me at risk. Potentially this puts cars next to me at risk too. The problem is currently under inspection by the dealer at Cardinale Hyundai in Corona, CA. Dealer so far has notified me the problem was unable to be reproduced and did not find any system or parts out of the ordinary. The vehicle has not been inspected by the police or insurance. This is a brand new 2022 model Elantra purchased on 12/31/2021. There were no prior warnings lamps, messages, or other symptoms prior to the failure. Dash cam video clips of both incidents are available upon request.
