1 complaint

2021 Genesis G70 engine shutting off at stops, often linked to the Idle Stop and Go (ISG) system or, in some cases, unexpected stalls. Possibly the automatic transmission's calibration leading to rough stops, or needing to restart the car if the ISG fails to restart the engine upon releasing the brake. 2.24.26:The vehicle stopped running and would not restart a busy intersection which involves my safety and other drivers. This has happened a couple times and I have replaced the fob batteries several times just in 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.

UNKNOWN OR OTHER,SERVICE BRAKES,ENGINE

1 complaint

Summary of Reported Behaviors Lurching: Commonly reported, often deemed a software/adaptive issue. Brake Issues: Commonly reported, often attributed to pad-to-rotor deposits, or in some cases, the recalled ABS module. I started my car in my work parking lot. When I put into Drive the car lurched forward aggressively. I immediately applied the brakes and they pulsated but did not stop the car. My car continued moving forward across the parking lot and right over a large railroad tie. I am very afraid of driving the car. If someone were coming across the driveway they would have hit me or if someone was walking to their car I could have hit them. 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!

ENGINE,FUEL/PROPULSION SYSTEM

1 complaint

The problem occurred while the engine was on, but I was idle in the drive thru of a local pharmacy. The car had been placed in park, but engine still running while waiting at the window. Suddenly, the car began to shake and multiple indicator lights illuminated then the car completely died. No indicator light was illuminated before this issue. I had driven the car on the interstate to and from a doctor’s appointment in a different part of town that morning with no discernible issues. The car smelled strongly of gas. I was able to restart the car to move it to a safe location for towing, but the engine struggled to start and the car continued to shake violently and more gas smell came from the car. It was turned off as soon as possible and it is now at the dealership for diagnostics and repair. There was a recent recall on my vehicle for a faulty high-pressure fuel pump. My car did not have a check engine light on and did not display the appropriate code to have the fuel pump replaced, so I only received a software update. Because the issue with the recent recall was sudden loss of power that could potentially cause a wreck, I feel that this issue is likely related to the same fuel pump problem but was missed under the previous guidance for repair. In this case, I was lucky it happened while sitting still instead of while I was on a major interstate, or I could have been seriously injured.
