Electrical system
26 complaints filed with NHTSA about the Genesis G70's electrical system. Dead batteries, warning lights, wiring, alternators, infotainment and electronic module failures.
Hyundai Motor America (Hyundai) is recalling certain 2015-2016 Genesis, 2017-2019 Genesis G80, Genesis G90, and 2019 Genesis G70 vehicles. Water may enter the starter solenoid and cause an electrical short, which can result in an engine compartment fire...
I noticed my driver head light starting to get condensation after doing further research i found it's a common manufacturer defect especially for the g70s. I took a further look by removing my front bumper & noticed 3 cracks starting from each screw on the front of the headlight mounting. after doing more research i found out it's a common manufacture problem with over torquing the screws & after inspection that's exactly why my headlight lense is cracking from bottom to top, as it's too much force where the screws...
are & with hot & cold temperatures plastics & such move creating them to break. my safety is put at risk due to the corrosion building in the headlight causing my blinker to malfunction & my daytime lights to stop working. i've got pulled over for my daytime lights not being on as it looked like a headlight was out. it also is causing my car to short sometimes itll turn of driver monitoring & lane departure all of it, i will have lights on the dash for a few seconds or minutes & my car will act strange even when going in reverse the backup camera pulls too much electricity sometimes causing it all to go black & car will die randomly then turn back on after 30min-1hr. & this all only started happening after the headlight started getting corroded. it's only been 2-3 months this has been going on. it doesn't happen all the time but what does happen all the time is my daytime light on driver side doesn't work. i have "check turn signal" warning light on 24-7 & maybe once a week the car will die knowingly even after driving a good distance.
Genesis sent out a map update. When it was updated, it stayed in the buffering. Mode, I cannot use my display. Phone does not work map, does not work. Navigation does not work. The dashboard speed limit does not work. Everything is in the buffering mode. Spoke to Genesis corporation complaint manager several times it's been over three weeks And they have no resolution to this problem. Never even sent out any type of email notice not to update the map because of the problem. They claim it's in all the models of the year, 2026. I feel the car is not safe. Speed limit on dashboard, not working safety issue, along with display, not working buffering. Cannot get to map navigation or phone
I own a 2022 Genesis G70. The driver's-side front headlamp assembly has developed significant and persistent moisture/condensation inside both sections of the lamp. The condensation does not clear during normal driving or after the lights have been operated for more than 30 minutes. The problem has now progressed from moisture inside the assembly to an electrical lighting failure. The driver's-side front turn signal is no longer functioning, the vehicle displays a "Check turn signal" warning and master warning indicator, and the turn signal hyperflashes when activated.
2022 Genesis G70: Severe moisture inside of headlights causing DRL, blinkers, headlights, etc., to short out or completely stop working. I had them replaced once under warranty and the same thing happened again. The Genesis dealership and Genesis customer care now refuse to take responsibility bc my warranty expired. They gave me a quote of $6078.95 (labor not included)!! My vehicle has never been wrecked, and there is no front end damage whatsoever.
I had the known reported issue TSB 25-BE-004G repaired and even after repair there is a burning wire smell that the dealer claims they can't replicate. We had the same issue with Genesis Plano initially and after driving the vehicle out of state we were stranded and took it to Genesis of Peoria where the issue was diagnosed. We are encountering the issue again and it is a fire risk hazard.
My car stopped in the highway
A 2024 Genesis G70 with 10,860 miles suffered a severe multi-system safety failure. While driving at highway speeds, the vehicle executed unexpected, unprompted automatic emergency braking (phantom braking) X2 with no forward threats present, creating an immediate highway collision hazard. Prior to this, the forward-facing cabin multifunction camera assembly near the rearview mirror experienced an electrical short and thermal runaway event, reaching a recorded surface temperature of 363°F and causing occupant...
blister burns to fingers. The failure caused a total collapse of the ADAS sensor grid, shutting off the Adaptive Cruise Control, Lane Keeping systems, HDA, etc. Additionally, the vehicle exhibits a severe rear differential/driveline humming, a drastic drop in fuel economy to 10.3 MPG, an A/C condensation line blockage flooding the lower undercover, and a replacement headlight housing with a dangerous 25-foot dead spot. Werner Hyundai looked at the vehicle which was 3 days days without resolution, and it has now been flatbedded to Jenkins Genesis of Ocala. The vehicle remains an unresolved, dangerous safety defect. This has been 39 days since this started. I have been trying to get Genesis Corporate to help me in this and it has been 40 days tomorrow with no avail.
Excessive condensation in the front headlight that constitutes a safety issue during night driving. Investigation into this needs conducted. I had the passenger side replaced under warranty but now I am outside warranty and the extended coverage excludes sealed headlight components. The dealership quoted $1600.00 to replace. Excessive for a safety item that should be recalled and manufacture should be forced to correct in a recall.
On 2/17/2026 I was driving from my home to a fast food restaurant one mile away from my home. After picking up the food I dropped the food off about 3 miles down the road to my family member at their work and drove the 3.3 miles back from my family members work to my home. I arrived at my home and was walking into the house around 12:30 pm my car was off and locked. During my drive the car performed completely fine, there was no codes, no noises, no smells, the car drove how i would describe as intended. But at...
around 12:45 my neighbors were banging and ringing my doorbell to tell me that my car was on fire. I proceeded to escort my aunt and my grandmother out of the home as i watched my car continue to smoke and watched the flames continue to rise. Once removed from the home i called 911 who took my information down and informed me that a similar call was received a new minutes before and that fire, police and EMS were on the way. I watched as the car completely engulfed in flames and the fire department worked to put the fire out. The car is completely lost and resulted in damages to my garage and my other car parked next to it. I know previous genesis models have had recalls for issues in the engine bay that could result in fires. I do not see a recall for my vehicle but given the unexplainable cause of the fire at this time, believe it may be beneficial to submit a report.
The contact owns a 2019 Genesis G70. The contact stated that while driving at an undisclosed speed, the audiovisual navigation screen displayed a blank screen. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The failure was persistent, and the audiovisual navigation screen was peeling and distorted. The contact was willing to pay out of pocket for the repair; however, parts were not available by any vendors. The manufacturer was made aware of the failure and a case was filed. The contact stated that several complaints were filed. The contact stated that coverage for the repair was denied. The failure mileage was approximately 45,000.
I was driving my vehicle when all of a sudden my passenger side headlight went out. I initially thought it was a light bulb I needed to fix. I turned the vehicle on after a few hours and the light was working again, but on occasion the light randomly turns off while I am driving. I looked online how to fix it and found multiple people with same issue and condensation build up which mine has without being damage.
The car randomly goes into LIMP mode when driving in every condition going at any speed, the car has a significant loss of power and needs to be restarted to gain power back. I have almost crashed because of this problem numerous times. Genesis dealership refuses to fix anything because the car doesn't bring back any error codes. This has happened to new and older G70s, there has also been numerous LEMON LAW buy packs under this exact LIMP mode issue being way more prevalent. I have gotten the supposed "fuel pump"...
recall which is what is directly affecting this issue and the problem persists. Genesis is aware of the issue and extended the dual pump warranty extensively. My car is extremely unsafe at random intervals during my daily commute. This issue is extremely dangerous and could cause a horrific crash. The car basically turns into a slug even when flooring the pedal to try and speed up, this makes merging and changing lanes on these New York highways extremely dangerous. There is an inherent problem with the design of this car in terms of how the fuel pump and fuel pump sensors operate. Genesis is aware of the issue and does nothing to fix it because wait for catastrophic failure of a competent and worse a crash that could result in a fatality.
Dealer did not complete recall while in service Nov 15 2024, service order shows parts are on back order. After 2 months I reached out to Corp who reached out to dealer. Both copr and the dealer ended up calling back just yesterday, however the message from copr stated the part is ordered it's way but the message from the dealer stated software upgrade needs to be done first before ordering parts. But why software upgrade was never done 2 months ago while performing service? I can smell excess gasoline 5 mins after...
remote started and my thermometer temp spikes significantly upon start. Car has only 12k miles. I am afraid car is going to burn down and they will do everything possible to avoid repair/replacement. I'm hoping this would create a record of historical events as well as poor service performance by the dealer.
When driving the vehicle it feels as though as it stalls due to choking all or some of the fuel getting to the engine. This is most prone when accelerating fast. It feels as though the fuel is shut off or severely diminished as the vehicle will accelerate, but at a fraction (crawl) of the normal output available and accomplished in the past.
Genesis issued safety recall for all 2019 G70's because the starter solenoid could be contaminated with water resulting in a potential risk for an engine compartment fire ( letter received from Genesis Motor America LLC. 8-1-24 ). Currently the solenoid replacement part for Genesis recall # 018G is not available @ any US dealerships; thus, requiring placing an order for said part. This represents a profound lack of timely customer service and is an ongoing problem with Genesis parts supply chain.
