2021 Genesis GV80 electrical problems

Filed Oct 6, 2026 · Electrical, Lights · IN

I am writing this complaint concerning the headlight assembly issue that applies to my vehicle. The headlight has a well documented record of suddenly failing. To my knowledge there has never been an official recall from Genesis to address this issue. The issue definitely causes a safety issue and the repair of this issue is not a straight forward matter. From the various reports i have read it is a design flaw that was never addressed and it is something that fails repeatedly. With an average repair cost of between $2500 to $4500 plus labor to repair a component that is essential to safely operating the vehicle this is a huge concern for me.

Component Affected: Electrical / Interior Cabin Comfort / HVAC SystemsDescription of Defect:I am reporting an active thermal defect in the dashboard footprint of my 2021 Genesis GV80 AWD 3.5T. Following a 35-to-40-minute dynamic road test under engine load, severe heat migrates directly from the engine compartment into the passenger cabin. The instrument cluster panel and surrounding dashboard structures reach an extreme, verified temperature of 110°F, while the adjacent passenger vents measure standard cooling at 80°F.This severe cabin heat soak began immediately following an authorized dealership replacement of the air conditioning evaporator coil, requiring complete dashboard disassembly. The thermal failure strongly indicates a compromised bulkhead/firewall seal, displaced steering column boot, or an uninstalled engine-bay thermal insulation blanket, which allows high-temperature engine bay heat and air pressure to blow directly into the vehicle's internal electronic housing components.Safety Hazard:An instrument cluster panel reaching 110°F poses an immediate safety hazard. It creates a severe cabin driver distraction, generates a risk of physical burns upon contact with vehicle instrumentation, and risks causing a thermal breakdown or electrical fire within the vehicle's primary digital dashboard wiring harness.Dealer/Manufacturer Actions:Two separate authorized Genesis retailers have refused to conduct a 40-minute dynamic road test to recreate the thermal failure. Technicians performed only a brief, 3-minute static idle test inside a shop bay and declared the vehicle "operating as designed." Genesis Motor America corporate customer care has used these insufficient 3-minute static shop tests to prematurely close my consumer safety case. The manufacturer refuses to diagnose this vehicle under dynamic driving loads or inspect the firewall seals under the 12-month dealer repair workmanship warranty. No crash or injury has occurred yet, but the thermal risk remain

On June 23, 2026, while operating my 2021 Genesis GV80, the vehicle's entire infotainment and system software rebooted without warning as I was leaving a parking lot. As a direct result of this reboot, the driver seat automatically moved out of my saved position. I was no longer able to reach the pedals and could not properly control the vehicle. This incident occurred while the vehicle was in motion. It took me several minutes to safely bring the vehicle to a stop, at which point I turned the car off and restarted it. Upon restart, all of my saved settings had been wiped. This is a safety defect, not a minor software issue. A seat repositioning without driver input while a vehicle is in motion constitutes a loss of vehicle control. Had this occurred at highway speed the consequences could have been fatal. I am aware that Genesis issued Safety Recall 031G for mid-drive infotainment reboots on other GV80 model years. I am requesting the federal safety agency investigate whether this defect extends to 2021 model year vehicles and whether a recall expansion is warranted.

Vehicle was parked in a residential garage with the engine off. A [XXX] child was secured in a rear driver-side car seat. The key fob was inside the vehicle on the passenger side. After the final door was closed, an adult immediately attempted to reopen the driver's door and found it locked. All vehicle doors were locked despite the key fob remaining inside the vehicle. No warning beeps, alerts, or messages were observed before or during the lockout. The cause is UNKNOWN. The vehicle appeared to lock with the key fob and child occupant inside. The outside temperature was approximately 90°F, and the garage was significantly hotter. The child was trapped inside for approximately 5–7 minutes, crying and visibly sweating. Because access could not be gained through any door, the passenger-side window had to be broken to rescue the child. This incident created a serious safety risk due to heat exposure and the inability to access a child occupant. The vehicle has not yet been inspected by the manufacturer or dealer at the time of this report. The suspected malfunction involves the electronic door locking and/or key detection system, but the exact cause is UNKNOWN.

Purchased CPO 2/28/24. Water intrusion defect manifested 5/28/24 (3 months) with electrical failures and dampness odor. Active leak discovered 9/25 - water leaked onto passenger during operation. CHILD HEALTH EMERGENCY: My daughter required THREE emergency room visits for severe allergic reactions after riding in vehicle - suspected mold/biological contamination from water intrusion. MANUFACTURER RESPONSE: Vehicle out of service 139 DAYS for warranty repairs (11/1-12/6/25: 35 days; 12/18/25-4/1/26: 104 days). Genesis inspection 1/19/26 but REFUSED to provide report claiming "attorney-client privilege." Genesis denied buyback 2/13/26. CURRENT CRITICAL SAFETY ISSUE: Vehicle returned 4/1/26. Passenger side view mirror now non-functional (safety hazard for lane changes/merging). WATER LEAK HAS RETURNED - same leak, same dampness odor. The "permanent repair" FAILED after only 2 weeks. Dealership REFUSING all repairs. 12/18/25 INCIDENT: While driving in rain, multiple safety system warnings illuminated simultaneously (forward collision warning, stability alerts) - suspected water damage to electrical systems. SYSTEMIC DEFECT CONCERN: Online research shows MULTIPLE 2021-2024 Genesis GV80 owners reporting identical water intrusion from sunroof drainage system failures. This appears to be manufacturing/design defect affecting many vehicles. REQUESTING: 1. Safety investigation of 2021-2024 Genesis GV80 sunroof drainage systems 2. Potential recall for water intrusion defect 3. Investigation of health hazards from mold/contamination 4. Investigation of manufacturer concealing defect inspection findings DANGER: Water intrusion causing electrical failures creates fire risk, safety system failures, and biological contamination health hazards. Children at highest risk for mold exposure injuries.

Notice condensation building up in driver side headlamp, then I received LED lights failure warning ⚠️ as i was driving. Now i driver side signal is not working some times and now i have about 7 warnings on dash from headlamp failure to collision sensor going off. I know since car is a 2021 and i'm the second owner it's out of warranty, but i speculate that this problem probably known now look at other reports and it only had 35K miles when I purchased it.

I'm reporting moisture in the driver headlight. I noticed a little moisture when I purchased it in October 25(used). Of course the warranty is up and the extended warranty doesn't cover replacement of assembly. Which is very pricey over $2000. I took it to the dealership to get it looked at but at the time it was still working but flickering alot, now it's completely out. I asked was it cracked and the service guy said no, this is something that we see sometimes. I didn't have any warning lights on prior to it going completely out. Now I can't get an expectation tag because of the headlight assembly needing to be changed. This is something Genesis must look into or offer warranties that cover expensive parts like that. It's definitely a hazard when both lights aren't working properly. I'm torn between trying to get it fixed or just letting the vehicle be repossessed and start over with something with a better warranty. I current have 6 alerts on dashboard since the light is completely out.
