2014 Hyundai Equus Problems

Engine failure/thrown rod in engine while drive. 90k miles.

The air bag suspension in these model cars are a known issue and they been known to fail almost every equus has this same problem and Hyundai knows about it

For the last year or so when driving my Equus the signal lights left or right side has been working intermittently. I can go months without any issues but lately it seems to be worsening. I transport my Mom that has dementia around and its scary because it seems never know when the lights may not work at all. People drive so crazy and if its dark or light they dont see my arm out the window. Please tell me that you can assist with this issue. I inherited this car from her brother that died of cancer, this car was his dream. I'm doing all I can to keep it in top condition. I can't replace the car, but I always try to keep it in top condition. Help please.

I am unable. To drive my car anywhere. Each time I start my car. All warning lights flash like a Christmas light. It causes the car to suddenly be slowed down. Or not to go full speed? I got the recall notice in the mail 4 weeks ago. My car has been parked in the garage for four months and has been there ever since. I need my car to go to work and I don't know what else to do. I can only do so much by using the cars of families and friends, but I need my car back because it's inconveniencing them too as well.

I am reporting a recurring safety-related defect in the headrest mechanisms of my 2014 Hyundai Equus. The first incident occurred in the front passenger seat. While driving, I lightly leaned my arm on the passenger headrest when it suddenly popped up with a loud, startling noise and occurring an road incident . The internal components crumbled instantly, requiring a complete replacement. This was a costly repair, which I first inquired about with the service department at AutoNation Hyundai in Columbus, GA. It was eventually repaired and completed at Columbus Body Collision, Columbus, GA On [XXX], the driver’s headrest failed in the same way. It popped out of position unexpectedly, and the internal structure again appears to have broken and crumbled, while I was parked at QuikTrip fuel station. Alpharetta, GA. This incident has made me concerned about occupant safety, especially regarding whiplash protection and the risk of the headrest becoming a projectile or collapsing under impact. Since both front seat headrests have failed in the same way, I believe this may indicate a design or manufacturing defect. I respectfully request that NHTSA investigate this issue and consider a recall so that affected Hyundai Equus owners are not left with expensive and unsafe repairs.

THE FRONT PASSENGER HEADREST SPLIT OPEN SPONTANEOUSLY. THERE WAS NO EXTERNAL IMPACT OR CRASH. THERE WAS NO PUSHING/PULLING OR OTHER PRECEDING INCIDENT TO CAUSE THIS. IT APPEARS THAT THE INTERNAL PLASTIC PART OF THE HEADREST FAILED.

On November 2014, purchased Hyundai Equus from Bob King Hyundai located in Winston-Salem, NC. Within a month, our headlights flashed on and off for a brief second. Occurred more often after that and the dealer checked the car to resolve problem. Nothing found. Months later, problem got more severe and once again dealer tried to fix and could not find a problem. Two or three times car went back to dealer and also a Hyundai dealer in Hickory, NC and once again, nothing was found defective. Over the past year, car has experience longer periods of light going off. Recorded on Dash-Cam at 1:00am on Interstate 77 lost of lights for 5 seconds at 70mph. I can supply a copy of that event if needed. I would say that I traveled over 300-500 feet without lights at that speed which could have been fatal. No warming lights or messages about the fault. I wrote the President of Hyundai Motor Company on December 3, 2022 with certified mail and return receipt and have not heard or been contacted by the company. I think this is a possible accident waiting to happen and injuries being incurred. Please help me with this issue as the safety of me and my family are at stake. Thank you for your attention into this matter. Cordially, Fred Crump 4958 River Bend road Claremont, NC 28610 Cell: 828-244-5555 hom: 828-459-7080

Headlight provides inadequate lighting, car not in compliance with FMVSS 108. Caused by the reflector bowl in the low beam HID projector losing its reflective coating. Heat/UV emitted by the bulbs burns it off. Visibility reduced to 38 feet. Happens on all years/trims. No known repair. Replacement headlight assemblies also affected.

THE STRUTS WENT OUT WHILE I WAS DRIVING. AFTER IT WENT OUT THE, TIRES WOULD TOUCH THE FENDER OF THE CAR. IT DAMAGED THE PASSENGER SIDE AND DRIVER SIDE OF MY FRONT FENDER. IT ALSO RUBBED THE TREAD AWAY FROM THE TIRE DUE TO RUBBING AGAINST THE FENDER. IT WAS NOT SAFE TO DRIVE BECAUSE IT WAS SO LOW TO THE GROUND THAT I ALMOST TORE THE FRONT FENDER OFF.

CAR STARTS ACCELERATING ON ITS OWN AFTER LONG HIGHWAY DRIVES ONCE CRUISE CONTROL IS DISENGAGED. MESSAGE APPEARS 'SERVICE ENGINE IMMEDIATELY. VEHICLE SPEED LIMITED DUE TO MALFUNCTION' WHEN IN FACT VEHICLE CONTINUES TO ACCELERATE. PLACING CAR IN 'PARK' CAUSES ENGINE TO REV OUT OF CONTROL. RESTARTING THE CAR DOES NOT SOLVE THE PROBLEM. THIS HAS HAPPENED TO ME FOUR TIMES IN THE PAST SIX MONTHS, ONLY AFTER DRIVING APPROXIMATELY 3 1/2 HOURS. I'VE READ NEARLY IDENTICAL DESCRIPTIONS ONLINE. DEALER HAS TO 'REPRODUCE' THE PROBLEM, DOES NOT ACCEPT VIDEOS, AND YET THIS IS ONLY HAPPENED AFTER A LONG DRIVES.

To: National Highway Traffic Safety Administration (NHTSA) – Office of Defects Investigation From: [XXX] Date: 2 June 2025Vehicle: 2014 Hyundai Equus Location: Columbus, GA   (Other driven locations: Buford, GA; Alpharetta, GA; Duluth GA)1. Summary of Vehicle Cyber Incident:My 2014 Hyundai Equus has been compromised through what I believe to be a remote cyberattack targeting the vehicle’s infotainment and navigation systems. This began shortly after I reported widespread digital and identity theft to law enforcement in Columbus, GA.2. Symptoms Observed: Navigation system lockout: The navigation system is entirely disabled. A satellite symbol with a circle and diagonal slash appeared on the interface and has not gone away, indicating a potential denial of satellite/GPS signal or remote access control. Rear Seat Entertainment (RSE) Override: The RSE system appears to be remotely controlled, with the interface appearing on my front console screen without input. I attempted to check the RSE control box in the settings menu, but it was consistently unchecked upon restart—as if overridden remotely. Video evidence interference: I recorded multiple videos of the system anomalies, including screen mirroring and control takeover. Some were blocked from sending or sharing; others went through under inconsistent conditions. Unauthorized device influence: I believe connected devices (iPhones, etc.) are being used as access vectors into my vehicle system.3. Timeline of Events: [XXX] (Sunday evening): After visiting the Columbus Public Safety Center and speaking with Deputies McBride and I. Sanchez about ongoing cyber intrusions (mobile, home, and vehicle), the car infotainment system began behaving abnormally that night. May 20, 2025 (Tuesday): I returned to Columbus Police Department to formally report the vehicle hacking. A CPD officer expressed genuine concern and said he would relay my case to Detective Gross. May 23, 2025: I visited AutoNation Hyundai in Columbus INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

Car is equipped with an air bag suspension system. There was a failure with the airbags around 18 months ( in 2016) of the car being put in service. I was driving on a hway at 70 mph w/grandkids in the car when the airgbags failed and the nose of the car immediately went down and the car started to veer. Luckily there was no other cars around me and I was able to slow down and pull off the hway. Coincidentally, I was just a mile from the dealership and immediately took the car to them and they gave me loaner car and took it in to repair under warranty. Approximately 18 months later, the air bags failed again and the car was just past warranty so I paid for the repair but contacted Hyundai and they reimbursed me.Hyundai told me they had problems with the design of the airbags and redesigned it which is what my car was then equipped with. The air bag system has failed twice more since then. The most recent incident caused many problems with the car. The air bag system had a leak and caused the compressor to keep filling them. I don't believe this compressor was built to be in use so much and caused my battery and alternator to fail, then the compressor itself finally failed. All this took place because of the faulty suspension air bag system. I believe Hyundai was negligent in not issuing a recall when the airbags originally failed back in 2016 as it could have led to a bad accident. I went on line and found many chat rooms with people having had the same or similar experiences to me. Hyundai is well aware of the problems with the system yet has chosen to ignore it and hope the problem goes away. Because of all the problems with this suspension, they have since done away with it and gone to a standard suspension system on all the newer cars that are similar to mine ( now Genisis). They need to do something for all the older cars still on the road with this old suspension. The date listed below is for the last incident mentioned in this document.

The problem is with the Accelerator pedal. It malfunctions, and is also known as a 'Dead pedal' at different times without warning and could cause an accident if it happens at the wrong time, like making a turn and the car will not accelerate, or move, just getting the car to move . I checked with a dealer if they have had any of these type reports and there answer was no they had not. It is very UN-nerving when it happens.

ENGINE FAILURE - CAR HAS 32K MILES; NEVER HAD ANY WARNING LIGHT APPEAR ON THE DASH; OUT OF NO WHERE DEVELOPED A KNOCKING NOISE. THE CAR WAS SITTING FOR APPROXIMATELY 2 WEEKS AND ONCE STARTED AND DRIVING A KNOCKING NOISE STARTED APPROXIMATELY 5 MINUTES INTO MY DRIVE; THEREFORE I BROUGHT IT IMMEDIATELY TO THE DEALER. NEW ENGINE IS NEEDED DUE TO EXCESSIVE SLUDGE BUILD UP AND OIL BLEEDING INTO THE ENGINE AND TIMING CHAIN. MANUFACTURER STATED IT'S NOT COVERED UNDER WARRANTY. A LOCAL MECHANIC SHOP TOLD ME THIS HAS BEEN NOTED IN A COUPLE OTHER SAME MODELS THAT CAME THROUGH THEIR SHOP ALTHOUGH THOSE OWNERS TRADED THE CAR IN TO GET OUT OF THE SITUATION THEY WERE IN. OIL WAS CHANGED IN ACCORDANCE WITH THE MANUFACTURERS SPECIFICATION ALTHOUGH NOT THROUGH A DEALER SINCE I DON'T LIVE CLOSE TO A DEALER. IF THE MANUFACTURER REQUIRES IT TO BE CHANGED OR MAINTAINED THROUGH A DEALER, THAT SHOULD BE DOCUMENTED IN THE OWNERS MANUAL. THIS MANUFACTURER SEEMS TO HAVE A LOT OF ISSUES WITH ENGINE FAILURES. THIS COULD HAVE POTENTIALLY CAUSED THE CAR TO STALL IN THE MIDDLE OF A BUSY HIGHWAY POTENTIALLY CAUSING TO HARM TO PEOPLE IN MY CAR OR CAUSE A SERIOUS ACCIDENT.

The right of my dash leather is lifting up, which will eventually affect the deployment of the right front air bag.
