2022 GENESIS GV70 Engine Problems

The coolant system on my 2022 Genesis GV70 has repeatedly failed despite multiple repairs. On April 2, Greenway Genesis diagnosed a coolant leak and replaced several components. The problem returned, and I brought the vehicle back on April 29 because the coolant appeared low again and the engine sounded louder than before. On October 25, Holler Hyundai confirmed another coolant leak, this time involving the integrated thermal management system. The recurring coolant loss places my safety at risk because it can lead to engine overheating, sudden power loss, or engine failure while driving. The issue has been reproduced and confirmed by two separate Genesis/Hyundai service centers. However, the root cause has not been identified or corrected, and the manufacturer has not provided a permanent solution. The vehicle has been inspected multiple times by authorized dealerships, and repair invoices are available for review. Despite these failures, no coolant warning light or dashboard message ever appeared, which raises concern that a sensor or monitoring component may not be functioning correctly. There were no warnings or messages at any point before or during the coolant loss. The vehicle is currently at Greenway Genesis and is available for inspection. Based on multiple repeated failures and the absence of any warning indicators, there appears to be an unresolved defect that could create a safety hazard while the vehicle is in operation.

The car loses power to accelerate in the middle of driving. I have to stop and turn it off and restart the car, then it will become normal for a little while before the same issue repeats again. It is really scary and can be very dangerous driving on a highway.

There were 3 incidents that have happened within a 2 week period driving this vehicle. 1. Driving in the middle of a 5 lane highway in busy traffic, car shut down. It almost caused a crash with me being hit from the back. 2. I was traveling around a deep curve, car stalled and was almost hit from the back by a transfer truck. was very thankful he could stop in time. I could not proceed to go to the right due to embankment. Very frightening. 3. Approaching a light that turned from red to green, car stalled at the light. It just cut off. It seems as if the company has no intentions on getting this problem fixed because it has almost been 3 months now since the recall. Does it take someone to be killed before they make the change to get these vehicles operable?

Random engine stalling creating safety incidents in traffic. Failure to diagnose the problem despite repeated attempts by 2 service depts.The problem became more frequent and severe until the car stalled and could not be restarted. Low pressure fuel pump assembly was replaced and the car is currently okay. This problem has cost me over 6 weeks use of my car and several dangerous traffic incidents.

Three weeks ago while returning to SC from Fl on I95, the engine jolted, stalled momentarily , and would not accelerate to keep up with traffic. I pulled over, turned off the engine, and re-started the engine. It started and sounded normal, as did the car diagnostic screen which showed nothing abnormal. An hour later and engine stalled again ( in traffic) and yet the diagnostic screen continued to show "all normal". Initially I suspected bad gas, but that theory proved wrong when, with a full tank of fresh gas, it stalled and stopped mid-traffic . In all these incidents I was very lucky to not have been hit by distracted driver. The car was towed to my Genesis dealer, and after a perfunctory check they said that using all their diagnostic tools, the car showed ZERO alerts. I refused their answer and insisted that it be test driven by one their staff. After receiving my permission to do so, one poor fellow drove it to his home, but it broke down well before arriving there. At this juncture they finally understood that they had an issue. Here is where it get's interesting, because my tech savvy son surfed several forums such as Reddit, Facebook and Genesis owners site, and discovered many references to fuel pump failures, stalling, near accidents and the like. I don't know how you rate the severity of car safety issues, but I suspect that total engine failure must rate pretty high. All I ask is that you rattle Genesis' cage and ask them how many fuel pump issues/ replacements they have had over the past two years. My hunch is that it is a material percentage. I find it unacceptable that with today's technology, a defect like this which can endanger lives on any road at any speed, is left unchallenged.

As I was driving on a heavily trafficked freeway, my engine shut off completely slowing down the car to a stop. I had to make an emergency exit, stop the car and restart it. After a restart I was able to keep driving for a few miles. Then it happened again, I got stuck at a roundabout in a dangerous location so I had to contact authorities for help on guiding traffic away. My car would not start and would just sputter when I tried to restart it. I had to get my vehicle towed and it's currently at the dealership with no clear solution. The shop manager tells me he's gotten a few vehicles with the same exact issue and there is no clear solution as no codes come up when this issue is happening. This was very dangerous and I could have gotten into an accident had I not been on the far right lane to make an exit from the freeway.

Vehicle came to complete stop on two separate occasions randomly twice in August 2023. (Power stayed on, engine stopped) - (Battery and Engine light came on) As of this point it is uncertain what component failed, but the reports of fuel injector/pump being the source of the problem is so common to the point that it's surprising that there hasn't been a nationwide recall. Right now, it's currently with the dealership service department.

This happened twice before I took the car back to the dealer for service. Both times I was driving the vehicle and it suddenly stops accelerating. The car suddenly comes to a stop. I continued pressing the accelerator and the car continued to quickly slow down to a stop. Both times I was in traffic and could have been rear ended or certainly could have caused an accident. The car is currently at the dealer and they have not called me yet to know what they found. I am a member of the GV70 Facebook group and I have seen many other owners who reported the same issue with their vehicle. It truly is terrifying and obviously a safety risk. Some members of the group stated that they were told it was the fuel pump. Genesis needs to get this issue fixed.

The engine lunged several times and then completely died. The car was towed to the dealership and the fuel pump has gone out. There are 7 GV70's sitting there with the same issue. Luckily it stalled in a turning lane and not while driving on the interstate. There is a problem!

I was driving down the interstate at 70 mph when my gas pedal stopped responding and the car was slowing down. Suddenly the car started beeping at me saying the engine was shut off and I needed to put it into park or neutral immediately. This happened a week prior on a 45 mph road and I was able to restart the car with no issues. This time, my car restarted when I got off the highway but immediately shut down again. It is incredibly dangerous to have a car shut down suddenly especially on a highway.

The contact owns a 2022 Genesis GV70. The contact stated that while driving approximately 60 MPH, the vehicle stalled. Additionally, while driving 30 MPH, the vehicle stalled. Additionally, while driving 65-70 MPH the vehicle stalled. The vehicle was restarted, but the failure persisted. There were no warning lights illuminated. The vehicle was towed to the local dealer however, the technician was unable to duplicate the failure. The vehicle was not repaired. The vehicle was taken to another local dealer, Gettel Genesis of Lakewood Gettel (5921 FL-64, Bradenton, FL 34208) but was not diagnosed or repaired. The manufacturer was contacted and opened a case, but no assistance was provided. The failure mileage was approximately 1,000.

Mileage: 1,000

Vehicle lost power while normal driving. This happened multiple times. All dashboard lights turn on, then vehicle shut down/shut off. Had to safely pull over to shift gear into PARK, then restart vehicle. Vehicle acceleration is very poor, the more it does this. Vehicle feels like it’s not being provided fuel. On my app, vehicle show “ALL SYSTEMS NORMAL”. Purchased brand new, only 8500 highway miles.

At 65 miles an hour on the interstate, I suddenly lost control of the accelerator and the car immediately began to lose speed. I pulled into the breakdown lane and came to a stop. I put the car in park and attempted to increase the engine speed by pressing on the accelerator. It was only when I jammed my foot to the floor that the engine responded. I then drove the car carefully to a Genesis dealer where I was told that this happens to the GV 70 when it is in Eco mode. The car is now at the dealer who will attempt to fix it, I hope.

Car has now lost power several times, including incident trying to cross multi lane road when it lost power and caused other vehicles to slam on brakes to avoid hitting me. The car lost power while merging onto interstate and vehicles had to avoid my car. It’s lost power just driving down the highway with cars swerving around me. I feel very unsafe but I need my car for work.
