2017 Genesis G80 Electrical Problems

My 2017 Genesis G80 3.8L, VIN [XXX], has approximately 43,840 miles and intermittently slips or shifts improperly between approximately third and fifth gears while driving and causes harsh jolts forward. Jenkins Genesis confirmed the condition, stated that the transmission was slipping from the 3–5 clutch area, and recommended complete transmission replacement. The malfunction is unpredictable and creates a risk of sudden loss or interruption of propulsion while merging, crossing an intersection, changing lanes or driving at highway speed. A driver may press the accelerator but not receive the expected forward power. A [XXX] infant is regularly transported in the vehicle. The vehicle also has a faulty right-front ABS wheel-speed sensor, a passenger seat-belt safety-system communication fault, and intermittent electrical or sensor warnings. Genesis TSB 21-AT-010HG-1 applies specifically to the 2017 G80 and addresses shift flare or harsh shifting during the 2–3, 3–4 and 4–5 shifts. It requires transmission-solenoid, wiring-harness and fluid inspection procedures. TSB 19-AT-014HG also addresses harsh or delayed shifting in 2017–2018 G80 vehicles and provides electronic shift-data testing. The written repair estimate does not establish whether all applicable TSB diagnostic procedures were completed. The model also has electrical recall history, including NHTSA recalls 24V-107 and 21V-161. I am not claiming the recalls caused the transmission failure, but the concurrent transmission, ABS, seat-belt and electrical faults warrant investigation. I request that NHTSA examine similar G80 complaints involving slipping, shift flare, delayed shifting and loss of propulsion.

I want to file a complaint regarding the recall issued for my car. I am concerned that Genesis has not issued a resolution at all and suggests parking the car. If it's unsafe and could ignite itself on fire, a remedy should be issued immediately. Offer us a different model and year or fix the issue. This is people's lives at stake.

Recall 24V107000 issued 2-13-2024 for compartment fire while parked or driving. I received such recall from Genesis within the past two weeks, now 5-13-2024, not promptly as it should have been since it is a high rise of danger to users and passengers. Today I called the Genesis Customer care, there remains no remedy, and the agent could not authorize a rental car. I could rent a car at my expense and submit a claim once the remedy is installed and I may be refunded that cost. Another agent should be contacting me in 3 to 5 days referring to case number 23267478. First, the notice was untimely. Second, no offer of sidelining the car and providing free of all charges, a rental car. Seems to me that our lives are at risk with no immediate help from Genesis. Thank You.

Oil sensor oil sensor in 2017 Genesis goes bad & Genesis knows it. When the vehicle is at a complete stop or is slowing down, oil pressure sensor comes on. Whenever you begin to accelerate, it goes off. Genesis ALREADY KNOWS this…which is why they ALREADY issued a recall on “DH” body style models (like my 2017 Genesis G80) in Korea, where the cars are produced, but REFUSES TO ISSUE A RECALL IN THE US MARKET. Upon googling I see that this is a common problem that an insane amount of people have also experience, again, enough of a problem to cause the Korean market, where these are manufactured to issue a recall. It’s not covered under warranty & the sensor is located so deep in the engine behind the manifold, it typically is a $800–1250 repair for a sensor that cost less than $200 due to the labor involved to repair it, however some local Genesis dealership quoted as much as $1600 to get it, replaced due to how much they charge per hour of labor. The quote from my local dealership in Houston Texas was $1250. This doesnt seem to be a problem w/ the new body style Genesis vehicles but is for mine the 2017 Genesis G80 (this body style is known as“BH” & was called the “Hyundai Genesis” in its 2015 & 2016 models, the 2017 model was 1st year as “Genesis G80” when Genesis broke off Hyundai to be separate but its the same body besides the badge which makes sense why the problem continued into the 2017 & 2018 Genesis G80) Not only should this not be such a common issue where you have so many people talking about how it happened to their car (& who knows how many people this happened to who didn’t post anything online) but Genesis owners in the US shouldn’t be on the hook to pay upwards of $1600 for an issue Genesis ALREADY KNOWS exists…which is why they ALREADY issued a recall on “DH” body style models (like my 2017 Genesis G80) in Korea, where the cars produced, but REFUSES TO ISSUE A RECALL IN US MARKET..clearly they know or wouldn't have issued recall in the Korean market

Hyundai Motor America and Genesis Motor America are recalling my 2017 Genesis G80 vehicle to address a risk with anti-lock break system (ABS) modules because it could malfunction internally and case an electrical short over time potentially resulting in engine compartment fire. I contacted the dealership and they claim that do not have the required part to resolve the issue. Also they do not have an estimated delivery date for the part. Please advise.

REGARDING NHTSA RECALL REPORT #21V-160 THERE SEEMS TO BE SOME CONFUSING INFORMATION REGARDING ACTION TO BE TAKEN BY THE VEHICLE OWNER. IN THE SECTION DESCRIPTION OF THE SAFETY RISK IT SAYS THAT THERE IS A RISK OF A FIRE WHEN THE VEHICLE IS "PARKED OR DRIVING". IN THE SECTION DESCRIPTION OF REMEDY IT STATES "CUSTOMERS CAN CONTINUE DRIVING THESE VEHICLES". IT SEEMS BASED ON THESE TWO STATEMENTS YOU'RE TAKING A CHANCE OF A VEHICLE FIRE IF YOU CONTINUE TO DRIVE. THE FIRST STATEMENT SAYS THE PROBLEM CAN OCCUR WHILE DRIVING AND THE SECOND SAYS YOU CAN STILL DRIVE THE VEHICLE. BASED ON INFORMATION FROM OTHER SOURCES QUOTING GENESIS THE INSTALLATION OF A PARTICULAR FUSE, LOCATED IN THE ABS MODULE WILL PREVENT THE CHANCE OF A FIRE. I'M ASSUMING THIS IS A TEMPORARY FIX SINCE GENESIS IS STILL TRYING TO LOCATE THE EXACT CAUSE OF THE PROBLEM. CAN YOU ELABORATE ON EXACTLY WHAT FUSE SHOULD BE REPLACED. MY LOCAL DEALERSHIP AND GENESIS NATIONAL CUSTOMER SERVICE HAVE NO CLUE ABOUT THIS FUSE STOP-GAP MEASURE AND ARE REFUSING TO LOOK FURTHER INTO THE MATTER. AT THIS POINT, BASED ON THE INFORMATION IN THE NHTSA REPORT I AM AFRAID TO USE MY CAR. CAN YOU PLEASE CLARIFY WHETHER OR NOT I CAN SAFELY OPERATE MY VEHICLE? CURRENTLY IT IS SITTING IN MY DRIVEWAY AS I DON'T WANT TO TAKE A CHANCE TRANSPORTING MYSELF OR FAMILY. THANK YOU.

THE CAR RANDOMLY DOES NOT TURN ON WHEN I PRESS THE START BUTTON. NOTHING HAPPENS. IT'S NOT THE KEY FOB EITHER BECAUSE ABSOLUTELY NOTHING WORKS IN THE CAR AT THAT POINT. I CAN'T OPEN THE TRUNK USING THE BUTTON INSIDE THE CAR, LOCK OR UNLOCK THE DOORS, NOTHING. THE CAR IS ESSENTIALLY A USELESS HUNK OF METAL. AFTER ABOUT 15-20 MINUTES THOUGH, THE CAR WILL JUST RANDOMLY TURN ON. I DON'T PRESS THE START BUTTON - IT'LL JUST TURN ON. THIS HAS HAPPENED ON 3 SEPARATE OCCASIONS SO FAR.
