Genesis G70 headlights problems

Filed Oct 31, 2026 · Driver assistance, Lights · NM

Headlights are defective and the seals give out and allow condensation to build on the inside making the light not function properly and then burn out as the condensation accumulates. Lane keep assist cannot function properly if traffic merges in, has trouble determining the lines and want to over correct as it completes the merge. Also drifts during the merge. Scary.

Water in both headlights, no external damage. Can see hairline cracks all along the rim of the headlights. The turn signals are intermittently not working due to water. The issue was confirmed by the dealer however they said even though it’s a documented issue, my car was over the 60,000 mile warranty. I was at 63,000. The repair is $6000.

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.

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.

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.
