Apr 17, 2026Lane DepartureBackup camera & sensors

I am filing a complaint regarding a safety recall repair for my vehicle that is not being handled in a timely or reasonable manner by an authorized dealership Delray Hyundai 655 NE Sixth Ave, Delray Beach. Vehicle Information: 2021 Hyundai Elantra SE VIN: [XXX] Recall Information: NHTSA Recall #24V879000 Recall #271 – Backup Camera Inspection/Replacement This recall involves a failure of the backup camera system, which directly impacts visibility while reversing and poses a safety risk. The manufacturer has indicated that a remedy is available; however, the dealership I contacted is refusing to perform recall repairs on weekends and is only offering an appointment more than a month out (scheduled for May 4th). Given that this is a safety-related recall affecting rear visibility, this delay is unreasonable and places me at continued risk while operating the vehicle. I rely on my vehicle daily and should not be required to wait an extended period for a safety recall repair that is already available. Additionally, limiting recall repairs to weekday-only appointments creates an unnecessary barrier for consumers who work standard business hours. I am requesting that this issue be reviewed, and that appropriate action be taken to ensure dealerships are providing timely access to safety recall repairs, especially when the defect impacts vehicle safety. Thank You INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The camera started to fail for a few days and then it was fine, then the blind spot started to fail and then the camera was useless.

High Beam Assist, Check Rear Cross-Traffic Safety System, Check Blind-spot safety system, Check forward safety system, Check Lane Keep Assist System, Traction Control disabled. ALL of those messages came on while driving. Rear backup camera quit working, reverse lights do not engage. No remedy for recall still. Vehicle is unsafe to operate without recall being fixed. This is my only transportation, FIX it!!!

Twice now when starting the car all the driver safety systems will show a warning that they are not working and the message is that the car is not save to drive. A bunch of warning signs will go off and the wheel locks. The brake system has also locked up. I captured it on video, but it won’t let me upload it here.

The vehicle pull the steering so quick, that I almost hit the car in the next lane. In another occasion it pull the car out of the Lane I was travelling on. I turned off the Lane keeping assist, and all seems ok.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Hyundai Elantra Hev verdict →
