Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.

The failure pattern owners describe
Owners report a constellation of electrical gremlins across the 2021 GV80. The most consistent complaint involves moisture intrusion into driver-side headlights, causing condensation, LED failure warnings, and eventual light outage—some describe this as widespread among GV80 owners and suspect poor headlight design. A few owners note water intrusion into the vehicle's interior (reportedly from sunroof drainage), leading to dampness odor, multiple electrical system failures, and repeated water leaks despite dealership repairs.
Battery drain is another pattern: owners describe batteries discharging rapidly without lights or equipment running, sometimes while driving, causing complete system shutdowns and infotainment loss. The infotainment system itself malfunctions independently—shutting down mid-use, losing radio/navigation/safety camera feeds, or taking 10+ minutes to power down. Owners also report random activation of the horn, window/door lock and mirror control failures, safety system warnings (forward collision, lane change alerts, stability warnings) triggering without cause or going on and off erratically. Some describe no diagnostic codes appearing when dealers inspect, yet failures recur or worsen.
One owner had junction boxes, audio units, and amplifiers replaced by Genesis field service engineers without resolving the issues. Another experienced a recalled water intrusion event causing multiple safety warnings while driving. Headlight assembly replacement costs exceed $2,000 and aren't covered by some extended warranties. Two owners mention dashboard warning lights numbering 6–7 at a time.
Failure modes owners describe
Headlight moisture and LED failure
Condensation accumulates in driver-side headlight assembly, causing LED failures and complete light outage. Owners report this is widespread among GV80s and suspect poor headlight design allowing water ingress through drainage path.
When: As early as 3 months after purchase (CPO 5/2024); noted at 35K miles; reported in vehicles from 2021 onwards
Symptoms owners cite: Moisture/condensation visible inside headlight lens; Flickering headlights; Complete headlight outage; LED failure warning on dashboard; Driver-side signal light not working intermittently; Multiple dashboard warnings (6–7 lights) triggered by headlight failure; Cannot pass safety inspection
Repairs/costs cited: Headlight assembly replacement costs over $2,000; extended warranties often do not cover assembly replacement. Genesis dealerships report parts out of stock, leaving owners without vehicles for extended periods.
Recalls/TSBs owners mention: Genesis advertises driver-side headlights out of stock; no recall issued despite multiple owner reports suggesting systemic design defect.
Water intrusion and electrical system damage
Water leaks into vehicle (reportedly from sunroof drainage system defect) causing dampness odor, electrical failures, and mold/biological contamination. Repairs fail; same leak returns within weeks.
When: 3 months after CPO purchase (5/2024); active leak discovered 9/2024; returned with leak 4/2026 after 139 days out of service
Symptoms owners cite: Dampness odor in cabin; Water leaked onto passenger during operation; Multiple safety system warnings during rain (forward collision, stability alerts); Electrical failures tied to water damage; Mold/biological contamination suspected; Passenger-side mirror non-functional after warranty repair
Repairs/costs cited: Vehicle out of service 139 days (11/1/25–12/6/25, 35 days; 12/18/25–4/1/26, 104 days). Multiple warranty repair attempts failed; same leak and dampness returned after 2 weeks of 'permanent repair.' Dealership refused further repairs.
Recalls/TSBs owners mention: Genesis inspection 1/19/26 but refused to provide report claiming attorney-client privilege. Denied buyback request 2/13/26. BBB Arbitration (narrative #1) ruled for vehicle replacement; Florida Attorney General ordered replacement; manufacturer did not comply within 40-day notice period and vehicle remained at dealership for 310 days without loaner.
Battery rapid discharge
Battery drains fully within one day or during driving without any visible drain (no lights, alarms, or equipment in use). Causes sudden system shutdown and immobilization.
When: Reported in 2021 model; occurrence timing not always specified
Symptoms owners cite: Battery dies within one day at rest; Complete system shutdown while driving without warning; Vehicle stops without advance warning; Risk of immobilization in traffic
Repairs/costs cited: Junction box assembly (main fuse box, driver side under dash) and junction block sub-assembly (rear fuse box) were replaced by Genesis field service engineers (May–August 2023) in one case; issue persisted after both replacements.
Recalls/TSBs owners mention: Genesis field service engineers attempted repair via component replacement (junction boxes, audio unit, external amplifier); manufacturer ultimately ordered vehicle replacement by arbitration/state attorney general after owner pursuit.
Infotainment system shutdown and camera failure
Infotainment system powers down during use, disabling radio, navigation, and safety camera feeds. System takes excessive time to shut down when parked.
When: Reported in 2021 model; timeframe of onset not always specified
Symptoms owners cite: Infotainment shuts down after 5 minutes of operation; Radio and navigation loss mid-use; Backup camera and warning system disabled; 10+ minutes required for full system shutdown when parked; Loss of critical safety camera feeds while driving
Repairs/costs cited: Audio unit (ref. 96560-T6600) and external amplifier assembly (ref. 96370-T6700) were replaced by Genesis field service engineers; issue recurred.
Recalls/TSBs owners mention: Audio unit and amplifier replaced under warranty; failures persisted.
Safety system and sensor malfunction
Lane change warning, forward collision warning, and stability alerts trigger randomly or go on and off erratically while driving. Multiple warnings activate simultaneously, especially during rain when water damage is suspected.
When: Reported in 2021 model; one event noted during rain (12/18/25) in water-intrusion case
Symptoms owners cite: Lane change warning light activates randomly; Forward collision warning triggers without cause; Stability alerts illuminate repeatedly; Multiple safety warnings fire simultaneously; Warnings appear and disappear intermittently during driving; Collision sensor triggers without cause
Horn spontaneous activation
Horn activates independently while vehicle is parked, occurring multiple times. Requires door unlock and additional tasks to disable horn.
When: At approximately 40,000 miles
Symptoms owners cite: Horn activates randomly while parked; Failure occurs multiple times; Horn difficult to disable
Repairs/costs cited: Owner suspected rear seat sensor involvement.
Recalls/TSBs owners mention: Dealer unable to duplicate failure; manufacturer made aware and case filed.
Door, window, and mirror control malfunction
Child window and door locks, mirror controls, and all window controls from driver door panel malfunction. Random recurring failures.
When: Specific timing not provided
Symptoms owners cite: Child window locks not functioning; Door locks malfunction; Mirror controls inoperative; Window controls from driver door panel fail; Random repeated events
Powertrain and transmission anomaly
Vehicle exhibits jerking, clunking, and unexpected acceleration behavior while driving. No warning signs; dealer diagnostics find no codes.
When: New vehicle; specific mileage not provided
Symptoms owners cite: Clunking or jerking while driving regardless of speed; Jerking during acceleration and deceleration; Unexpected acceleration after light throttle input; Sudden jerking in traffic requiring hard braking; No warning lights before event
Repairs/costs cited: Dealer claimed faulty fuel pump on initial complaint; clunking persists.
Recalls/TSBs owners mention: No codes found on inspection despite repeated complaints.

I have had my GV80 prestige since 2021. Recently the headlights started developing moisture in them. I found out this is an issue with a lot of the genesis. The lights are poorly designed causing water to flow down through the headlights into the light module which makes all the lights on that side of the vehicle inoperable. The vehicle will not pass safety inspection. Currently Genesis…
