GENESIS Complaints

My starter failed. I took it to a triple AAA authorized mechanic. He did a full diagnosis of the entire starting system and determined that the starter needed to be replaced. He noted that water caused it to fail.

I moved to Reno, NV where I need to merge onto route 80 everyday. During several attempts to merge onto 80, my Genesis GV70 stopped accelerating at 42 MPH, roughly 5000 RPMs and I was almost rear ended on two occasions because of the 'stalling' of the vehicle. An 18 wheel truck almost hit me because I couldn't accelerate past 42 MPH. Luckily, I was able to pull off the road. There was no warning light or check engine light on the dashboard. This was not a one time issue. Everytime I tried to merge at high speeds the car would not respond. I've attached a video that shows the issue. Genesis towed my car to a dealer in Mountain View CA. I did notice that I was leaking radiator fluid in the days prior to my incidents but when I checked the overflow tank, it was full. Again, there were no check engine lights on the dash. The Mountain View Genesis service manager replicated the issue and discovered that a small rock had come through the bottom grill and damaged the intercooler radiator. He unequivocally stated that "it's a design flaw in the lower grill. The grill has such a wide opening that foreign objects can enter through the lower grill." He went on to say that the intercooler radiator sits below the regular radiator and is made of a softer metal than the regular radiator which makes is more susceptible to damage. He also said that another Genesis GV70 came into his shop the same day with the exact same issue. The cost of the repair was $2,200 dollars to replace the intercooler radiator. (the intercooler was on backorder which may be demand) I opened a case with Genesis and they say that the repair is not covered under a warranty. The Genesis owners forum has numerous complaints of 'lack of acceleration' issues. Someone polled owners and 28 people responded that they experienced a similar lack of acceleration dangerous situation.

Car stopped taking a charge. ICCU and fuse seem to have died. This widespread problem needs to be addressed by the manufacturer. It's dangerous and careless to not have fixed the issue years later.

My vehicle is covered under Safety Recall 023G involving an ECU update, inspection for DTC P0088, and high-pressure fuel pump replacement if inspection criteria are met. The recall is listed as completed, however the high-pressure fuel pump was not replaced, and the dealer has refused replacement. Only an ECU update was performed. I continue to experience fuel pressure–related symptoms consistent with the recall condition. The dealer has declined further action and has not provided documentation showing inspection results or justification for non-replacement. I believe the recall was improperly completed, creating a safety risk due to potential loss of engine power or stalling. I am requesting NHTSA review.

While driving car, I heard a "pop" sound coming from the back seat, my ICCU had failed and then there was a sudden loss vehicle power and the car went into a limp mode. The car only had 5,650 miles on it. This is a serious safety hazard. The car was towed to the dealership and a new ICCU was installed. The replacement part was the same model number that had failed. I was advised by the service adviser that I could possibly experience another ICCU failure in the future.

The digital instrument cluster in my 2024 Genesis GV70 has failed multiple times while driving. The vehicle was taken to the dealership on December 20, 2025 for instrument cluster malfunction. The vehicle remained in the shop for approximately four weeks, and the instrument cluster module was replaced. The vehicle was returned to me on January 19, 2026 with representation that the issue had been corrected. On February 8, 2026, only 20 days after the repair, the instrument cluster failed again while the vehicle was in operation. The panel was completely inoperative for approximately two hours. During the failure: Speedometer was not visible, Warning lights were not visible, Fuel gauge was not visible, Safety indicators were not visible, signal lights not working, Automatic Engine Start/Stop system control not working. Entire console goes out.  Operating a vehicle without access to critical driving information presents a safety hazard.

? 1. The Airbag Control Unit (ACU) and associated restraint-system components appear to have malfunctioned. The Event Data Recorder shows inconsistent airbag deployment staging, a pretensioner firing while the belt was recorded as unbuckled, a seat-track sensor fault, unsupported occupant-classification data, incomplete curtain-airbag deployment during rollover, and missing crash-event data. Yes, the vehicle and the full 29-page EDR report are available for inspection upon request. ? 2. The restraint system did not protect the occupants as expected. I suffered chest injuries from hitting the steering wheel, and my passenger sustained injuries to their hand and arm. These injuries occurred because the driver airbag did not deploy correctly, the pretensioner logic was inconsistent, and the curtain airbags did not deploy on the driver side despite multiple full vehicle rotations. The system’s irregular behavior increased the risk of serious injury or death. ? 3. No. The issue occurred during a crash event and cannot be safely reproduced. However, the malfunction is confirmed by the vehicle’s own Event Data Recorder, which documents the deployment irregularities, sensor faults, and data-integrity issues. ? 4. The vehicle was inspected by insurance representatives after the crash. The manufacturer has not performed an engineering-level inspection of the Airbag Control Unit or restraint-system logic. The EDR report was obtained through the insurance process and serves as the primary source documenting the malfunction. ? 5. No warning lamps or messages appeared prior to the crash. There were no symptoms indicating that the airbag or restraint system would malfunction. The failures were only discovered after reviewing the Event Data Recorder.

The contact owns a 2018 Genesis G80. The contact stated that while driving at an undisclosed speed, the contact's vehicle was involved in a crash. The contact stated that the vehicle crashed into a deer, and then crashed into a hill. The vehicle spun around three times and rolled over after crashing into the hill. The front driver's air bag did not deploy. The contact stated that no warning lights were illuminated. A Police report was filed. The contact sustained bruises to the chest and back pain. The passenger who was seated in the front passenger's seat sustained bruises. No medical treatment was provided at the scene of the crash, however the contact later visited her primary physician. The vehicle was towed to the contact's family members' residence and later towed to the contact's residence. The insurance inspection confirmed that, according to the EDR, the front diver's air bag skipped stage one. In addition, the contact was informed that an unknown recall had been initiated for the front passenger's air bag for the vehicle. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the aftermarket seat covers were the cause of the steering wheel's functionality not functioning as intended. The contact was informed that the aftermarket seat cover was the cause of the driver's side air bag not deploying. The contact stated that the seat covers were purchased after the crash to cover the damaged seats as a result of the crash. The failure mileage was approximately 126,000.

Tried to start the car and got a several warnings of "turn off vehicle and check EV system" and "power limited". This is similar to the ICCU failure issue other people have reported.

My vehicle failed while in motion. I lost power to the vehicle and power steering. Just before the car failed, I heard a pop and a warning light came on that said "Check Electric Vehicle System". The car's ICCU failed and caused failures of the battery and 12v battery. My safety and everyone on the road around me's safety was put at risk when I lost the ability to accelerate or use power steering. The car was towed to a dealer and the dealer confirmed the issue. The ICCU failure and failure of the vehicle while in motion is directly related to a previous safety recall (025G) for which repair work was done on my vehicle. The recall repair was ineffective as the very issue it was intended to resolve still happened to me in a 1 year old car with only 8,000 miles.
