2019 Genesis G70Engine & coolingFuel system

I had a sudden loss of power when driving and the car would not start back up. It could be due to the current HPFP recall that is active on the car. The Genesis Southfield, MI dealership was informed about my car being a Canadian VIN and they accepted to take my car. So I tow it there for $500 and then they refuse to work on it saying they "are not allowed to do recall campaigns on Canadian VIN". I called Genesis Canada to which they said if the dealership calls them they can send them the foreign work process...

documentation. However the dealership was adamant on not performing the recall and I had to send it to an independent mechanic. Wasting $700 total on tows which they did not even acknowledge. The car is currently getting diagnosed however a manufacturer dealership MUST be responsible for active recalls, especially since my car is registered in the USA. Genesis needs to reimburse me if I have any out of pocket costs due to the recall.

2023 Genesis G70Engine & cooling

My 2023 Genesis G70 has recurrent, intermittent engine power loss and stalling while driving, including on highways. The check engine light comes on intermittently and the engine can run roughly. After a stall, restarting can restore operation, but the issue recurs. Unexpected power loss in highway traffic puts occupants and other road users at risk. The exact failed component is UNKNOWN. The vehicle had repeated prior visits to Genesis of Auburn without resolving the concern. Southtowne Hyundai and Genesis of...

Newnan held it from August 19 to September 4, 2026. Repair order 184931 documents the stalling complaint and reports of misfires on cylinders 2, 4 and 6. It records multiple test drives, inability to duplicate the concern, and no stored or active diagnostic trouble codes at that visit. The vehicle was returned without a repair for this concern. On September 9, 2026, five days after pickup, the same stalling/loss of power recurred. The Genesis diagnostic system reported P0300, P0302, P0304 and P0306 at 67,847 miles immediately afterward. I sent Genesis Consumer Affairs videos and the diagnostic information that day. On September 16 I requested another appointment and a loaner because of the continuing highway stalling. After a September 21 follow-up, the dealer offered late October diagnostics with no rental. Genesis later offered an expedited September 23 appointment; I requested September 24 because of a transportation constraint. The condition remains unresolved as of this report. I request review of this recurring safety concern. Service records, diagnostic screenshots and videos are available. The vehicle can be made available for inspection by arrangement. Precise driving speed and the first occurrence date are UNKNOWN.

finds a pipe with my turbo that is deteriorating and now they want to change that and it just keeps my motor keeps getting hot you getting excessively hot. I mean I'm going through two or 3 quarts of all a week and my car. I have four Genesis vehicles I have two G7 I have a G 80 and I have a GV 70 and this is the only one I'm having problems with and it is the and I'm very disappointed with the situation now because I feel like it's just they just want me to keep putting money into this and I'm and now I'm gonna and my car is only four years old. It's been paid off since I bought it and I've had no problems in all of a sudden. It's like I'm gonna be out $6000 soon and it's just I don't understand why what's going on and then I see that there's a recall that I'm not part of with my VIN number, but yet every single one of the problems that I'm having is because of that and not to mention, they have me change all the sensors and stuff that I probably didn't even need to change so I'm very outright right now because they're trying to charge another $2000 to do this pipe when they done all these other things and they could've done the pipe first I feel like they're just trying to get money out of me to mention now if I drive my car for more than 45 minutes, the engine light comes on and it goes into lag motor just started losing power and I have to pull over and Stop and they add oil and then I can drive again absolutely insane

2019 Genesis G70Engine & coolingFuel system

I own a 2019 Genesis G70 3.3T Twin-Turbo V6, VIN [[redacted]], with approximately 122,000 miles. Twice within approximately two weeks, the vehicle has suddenly and unexpectedly experienced a near-total loss of propulsion while being driven. Without warning, the engine begins shaking and sputtering severely, the Check Engine Light illuminates, and the vehicle provides almost no usable acceleration. The engine does not completely stall but operates barely above a stalled condition. After safely stopping, turning...

the vehicle off, and restarting it, normal engine operation and full power immediately return and the Check Engine Light extinguishes. The vehicle may then operate normally for days before the condition occurs again without warning. This creates a serious safety hazard because the failure could occur while traveling at highway speeds, merging, changing lanes, or crossing traffic. A sudden near-total loss of propulsion under those circumstances could result in a serious or fatal collision. I have found reports from other Genesis G70 owners describing substantially similar intermittent loss-of-power conditions that temporarily resolve after an ignition restart. Genesis has also issued safety recalls involving G70 powertrain-related conditions, including NHTSA Campaigns 24V-528 and 24V-191. I have formally notified Genesis Motor America in writing and requested immediate investigation and repair. I am submitting this complaint so NHTSA has an independent record of this recurring and potentially dangerous loss-of-propulsion condition and can determine whether it represents a broader safety defect affecting Genesis G70 vehicles.

I had the known reported issue TSB 25-BE-004G repaired and even after repair there is a burning wire smell that the dealer claims they can't replicate. We had the same issue with Genesis Plano initially and after driving the vehicle out of state we were stranded and took it to Genesis of Peoria where the issue was diagnosed. We are encountering the issue again and it is a fire risk hazard.

While accelerating to highway speeds, the vehicle suddenly experienced a significant and continuous loss of power. Even with the accelerator fully pressed, the vehicle would not increase speed beyond roughly 50 mph. Based on the behavior and previous service history, the issue appears to be related to the engine, fuel delivery system, or overall powertrain. The incident created a serious safety concern for both the occupants and surrounding traffic. The vehicle could not properly accelerate, merge, or respond to...

normal highway conditions. Hazard lights had to be activated, and the vehicle remained in the slow lane for an extended period to avoid faster-moving traffic. The issue was consistent and repeatable throughout the drive. Multiple attempts to accelerate resulted in the same lack of response, and the loss of power persisted for the duration of the trip. The vehicle has not yet been inspected following this occurrence because when turned off and turned back on, the issue goes away and happens sporadically. It is also worth noting that the vehicle previously underwent a manufacturer-covered repair involving the high-pressure fuel pump, for which a warranty extension had been issued. This loss of power occurred after that repair was completed. No warning lights, alerts, or prior symptoms were present before or during the incident. Overall, the sudden loss of propulsion at highway speed posed an immediate safety risk, as the vehicle was unable to maintain appropriate speed or safely maneuver with traffic.

case that was the problem. It has not been inspected because it was just involved in another incident yesterday and I have been only making it to work as I am afraid to drive it. The warning came up on the dash after the car shut off. The vehicle can be picked up and inspected at any time. I do not have another vehicle or rental option.

I have not driven the car again since the incident so no one has inspected the vehicle. The front collision warning started coming on the day before. I did not notice it on during this incident. This car is only 5 years old and I am now terrified to drive it!

around 12:45 my neighbors were banging and ringing my doorbell to tell me that my car was on fire. I proceeded to escort my aunt and my grandmother out of the home as i watched my car continue to smoke and watched the flames continue to rise. Once removed from the home i called 911 who took my information down and informed me that a similar call was received a new minutes before and that fire, police and EMS were on the way. I watched as the car completely engulfed in flames and the fire department worked to put the fire out. The car is completely lost and resulted in damages to my garage and my other car parked next to it. I know previous genesis models have had recalls for issues in the engine bay that could result in fires. I do not see a recall for my vehicle but given the unexplainable cause of the fire at this time, believe it may be beneficial to submit a report.

While driving at highway speed, the vehicle experienced a sustained loss of motive power. Despite the accelerator pedal being fully depressed, the vehicle would not accelerate beyond approximately 62 mph. Based on the symptoms and prior service history, the malfunction appears related to the fuel/propulsion system, engine, or powertrain. The vehicle is currently parked and available for inspection upon request. This failure placed the safety of the occupants and other motorists at risk. The vehicle was unable to...

safely accelerate, merge, pass, or respond to traffic conditions. Hazard lights were activated, and the vehicle was forced to remain in the slow lane of the highway for an extended period to avoid being struck by faster-moving traffic. The problem was reproducible and occurred repeatedly during the same trip. Acceleration was tested multiple times, and each attempt resulted in the same loss of power with no response to throttle input. The condition persisted for the entire drive. The vehicle has not yet been inspected following this incident. However, the vehicle previously received a manufacturer warranty repair involving replacement of the high-pressure fuel pump, and the manufacturer has issued a warranty extension for this component. The loss of motive power occurred after that repair. No warning lamps, alerts, or messages were observed prior to or during the failure. There were no warning symptoms immediately preceding the loss of motive power. This loss of propulsion at highway speed created a serious and immediate safety hazard due to the inability to maintain normal traffic speed or maneuver safely.

under 50 mph and forcing me to immediately pull over, which created a serious safety risk to myself and other drivers due to the sudden inability to maintain highway speeds. The issue has been confirmed by an authorized dealer through repeated diagnostic scans showing the same fuel system fault codes, and the dealer has determined the fuel pump now requires replacement, indicating the recall update did not resolve the underlying failure. The vehicle has been inspected by the dealer on behalf of the manufacturer, and prior to the failure the check engine light illuminated and has remained on since, with symptoms escalating abruptly and occurring without warning, making this an ongoing and unpredictable safety issue.
