ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEMThe car is a ticking time bomb and dangerous to the public. My car has stalled and broke down in the highway several times. Had to wait for 3-6 hours tow trucks in between. The latest one, I reported to the service advisor that my car stalled all of a sudden at a neighborhood. She told me they didn't find any error codes therefore there is nothing wrong with the car. I was also told to keep driving it till it breaks down and only come back to them when that happens. Lo and behold not even 3 days later on Christmas night it broke down on me and had to wait in the middle of the highway in between the highway and on ramp. Had to wait several hours in the cold as the car would not start for a tow truck to come. After dropping off the Vehicle at the same dealership again it will be almost 4 days and they have not touched the car since. They don't know what's wrong with it because it doesn't show an error code on their GDS scanning tool. Now it wont even scan because the car will not start. Therefore they don't know how to fix it. Rather than trying to look for the source of the issue, they only replace the damaged parts caused by the issue. Same exact scenario happened back in September, car broke down on the highway, 6+ hour wait for a tow truck, the service advisor said the Catalytic Converter melted and they just went to replace that and not what led up to that issue. The stalling has happened several times, I would lose all power and just coast to the side of the road with check engine, battery, oil light, everything on, on the dash and if the onboard Bluelink system does not get a code then the service center will not know what to do with the car. They heavily rely on the error code before they can attempt to do anything to the vehicle. My ODB scanner shows me all the DTC codes but the dealership just brushes it off and doesn't listen to the customer. I keep telling them you don't get fouled spark plugs and melted catalytic converter if there's no issues.
