I had noticed my GV70 had not been functioning correctly for about 3 weeks prior to scheduled maintenance due. The vehicle has become slow and sluggish accelerating. Was concerning as I had pulled out in traffic not expecting limited acceleration. NO check engine or warning signs displayed. I traveled from Midland, TX to Genesis of Grapevine for scheduled maintenance to be performed. Later that day was informed that my radiator had been crack. Due to road debris and my extended warranty would not cover it most likely. Of course road damage would have had caused this as my expensive vehicle has never been off road. After researching Genesis Forum I have learned that this is a structural defect that has been corrected on later models. So Genesis has obviously taken corrective measures to prevent this from happening on newer year models. This is something that should have been corrected with a recall. Now it is being deemed as road damage. Please look into this.

While driving on the expressway during rush-hour traffic, multiple warning lights illuminated on the dashboard and several error messages appeared. At the same time, the vehicle began repeatedly jerking while I was traveling at low speed in heavy traffic. I continued driving for approximately 10 seconds, but the jerking continued. Because of the unusual vehicle behavior and the warning messages, I pulled over to the side of the road. After stopping, I attempted to shift the transmission into Park, but the vehicle would not allow me to change the gear. I turned the engine off and restarted the vehicle, but I was still unable to shift the vehicle into Drive. I attempted this three times. On the third attempt, the vehicle finally allowed me to shift into Drive, but the check engine light remained illuminated. I subsequently took the vehicle to the dealership for inspection. The dealership stated that they updated the vehicle's software and reset the error codes. I am reporting this incident because the vehicle unexpectedly began jerking in heavy traffic, displayed multiple warning/error messages, and temporarily prevented me from changing the transmission gear. The inability to shift the vehicle normally and the sudden jerking created a potentially dangerous situation while driving on the expressway.

My 2022 Genesis G70 has experienced repeated turbocharger and exhaust-system problems. In August and September 2025, the vehicle was serviced for exhaust/turbo-related gaskets and clamps and a misfire condition. It later developed knocking, sluggish acceleration, and additional turbo problems. The dealer replaced the turbo wastegate in February 2026, and additional turbocharger repairs were subsequently required. On July 28, 2026, an exhaust leak near the turbocharger was diagnosed. While operating the vehicle, I experienced headaches, dizziness, chest discomfort, and irritation of my eyes and nose. I was concerned that exhaust fumes could enter the passenger compartment and impair my ability to operate the vehicle safely. I sought medical care for a headache on July 29, 2026. I have not received medical confirmation of carbon-monoxide poisoning. The exhaust leak was repaired in August 2026, but on August 17, 2026, the leak appeared again in the same location. The condition has therefore been reproduced and confirmed through service inspections and has recurred after repair. The vehicle and its repair records are available for inspection upon request. Previous symptoms included a check-engine light, misfire, knocking, sluggish acceleration, and exhaust-related concerns. The vehicle has also experienced several extended periods out of service for repairs.

I do not know exactly what component failed. All I know is that the vehicle lost power while my wife was driving our children to school at around 8:15 A.M. on February 24, 2026. The vehicle slowed down on its own and could not accelerate when my wife pushed on the gas pedal. There were no warning or check engine lights on the dashboard. Luckily, this happened in a residential neighborhood where traffic is low. This could have caused an accident and/or fatalities if she was driving on busy street or a highway at the time. I contacted Genesis Customer Care. They scheduled me for a service appointment to get the vehicle checked. The vehicle was checked for codes, but nothing came up. They checked the vehicle log but did not find any clues. They told me that everything was normal and they assumed that it was most likely due to an over-the-air update that caused a system reboot. I believe the problem still exists and that it is a matter of time before it happens again.

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.

We were driving up a mountain pass in a great deal of stop and go traffic. The engine died and a check engine light came on. It was difficult to get the engine started, but it did start. We called the genesis service line and they said that it was a warning and ok to drive but to take it into be looked at. We proceeded up the mountain pass slowly, but when we were out of traffic and needed to give the engine gas to accelerate up the hills, the engine would not speed up. We were driving on interstates where we could only go 25 mph up the hill when others were speeding by us driving 60+ mph so we had to drive with our hazards in the right lane and hope not to get hit. When going down the hills, the engine would speed up, but any hills meant the speed would decrease even when you were engaging the gas. According the warnings we receive via Genesis in my app, the problem was Diagnostic code P0087F0 and said it was powertrain and the subsystem was EMS. We took the vehicle into the dealer and they were unable to recreate the problem. They reset the computer to the manufacturer reset. The vehicle is available for inspection upon request. This should not be happening on a 2023 car with 5000 miles on it.

Engine, transmission/propulsion and or fuel system is impacted. Vehicle loses power and pressing the throttle doesn’t increase the engine rpms and or vehicle speed. It happens randomly at both city and highway driving speeds. It’s almost like the gears aren’t shifting or the vehicle doesn’t increase the speed. Sometimes a it would work fine after a key cycle. I’ve had a few instances of it and there’s no check engine light. I took a video of it from last night when it happened. It’s a big safety risk trying to pass other cars. On the freeway when it happens the vehicle doesn’t cross 60mph hour. It’s very delayed, and then if I cycle the throttle or change gears or downshift manually it’s jump 2000-3000 rpms and would still struggle to get past 80mph. I bought my vehicle in MI, noticed these issues on my current trip to FL. I intend to have a MI dealer diagnose it. Seems difficult without a check engine light or DTC.
