2023 Genesis GV70: check engine light

Filed Sep 23, 2026 · Engine · TX

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.

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.

I purchased the vehicle on March 30, 2023, & my Check engine light has been on eleven times since June 2023. I was involved in a car accident on August 25, 2023, where the car appeared to have no gas. However, gas was in the vehicle, and the brakes were not operating correctly as I had to continue pumping the brakes to stop the vehicle. Furthermore, there is over $15k in damages and counting. I have been placed off work due to the injuries sustained in the vehicle accident due to the negligence of the manufacturer & dealer. I have left several messages for my Case Manager, [XXX] for several days, with unsuccessful attempts. [XXX] finally contacted me on 8/30/2023 @ 3:08 pm, apologizing for Genesis not living up to the “white glove” expectation advertised, and then she asked me what she could do for me. The call with [XXX] lasted 7-8 minutes. However, I constantly repeated myself, informing her of the information I stated in this email regarding my check engine light; my vehicle was serviced on Friday, June 30, 2023 (See Service History Below). Since then, the check engine light has illuminated nine other times with some of the same and or different codes. I had an appt to return my vehicle to the same dealership for the second time since June, as the dealership had the car for approximately eight/nine days. On August 12, 2023, I scheduled an appt. Per the system availability of August 25, 2023, @ 10 a.m. for Valet Pick-up. For confirmation of the scheduled appointment, I called GenesisCare on 8/23/2023, and the rep informed me that they did not have an appointment for me in the system. Furthermore, on several occasions, when I have attempted to make an appointment, the system does not recognize the appointment scheduled via the app or desktop. I was only informed about the technical issues with the software application via phone and desktop when I spoke with the service manager [XXX] ) Genesis of Atlanta. The accident occurred 8/25/2023.

No warning and no engine light when gas pedal is pressed down there is little to no acceleration. I was pulling out in the middle of traffic when this malfunction occurred. I could have been T-boned by oncoming vehicles and killed. It was not until I drove the vehicle a little longer that the engine light came on. The vehicles notification center showed a malfunction of the transmission. A diagnostic scan showed trouble codes P0763-Shift Solenoid C-Electrical and P0880-TCM Power Input Signal-Malfunction.

On 5 separate incidents, on two separate days, when traveling at highway speeds, the car lost power and began to decelerate. After a moment the engine died. In each case I was able to coast onto the shoulder but this is a serious safety issue. On 6 further incidents, the car lost power and died in other circumstances, including in a driveway immediately after starting up. These cases were not as dangerous as the highway failures. Check engine light does not come on. No codes thrown. Dealer will not inspect for another month. Dealer has not yet inspected. Fuel, all fluids, all general maintenance is in good condition. Vehicle has less than 14k miles. Car is available for inspection upon request.
