| Engine And Engine Cooling problems |
Component that failed: a high-pressure fuel injector (cylinder 2). The failed injector and engine wiring harness are available for inspection on request. The vehicle is currently at an authorized dealer. What happened: while driving at approximately 35-45 mph under light throttle in normal traffic, the engine began misfiring without warning. The misfire worsened rapidly over several seconds and the engine ran roughly enough that I pulled off the road. A strong burning smell was present immediately afterward. The vehicle has continued to misfire since. Safety risk: the failure caused a sudden and unexpected loss of engine performance while the vehicle was moving in traffic, with no prior warning. Had this occurred at highway speed, in a merge, or in an intersection, the loss of power could have created a serious hazard. The strong burning smell suggests unburned fuel reaching the exhaust system and overheating the catalytic converter, which raises a fire concern. Confirmed yes. An independent service center and an authorized dealer both diagnosed the failure. Ignition components were ruled out by swapping spark plugs and coils between banks; the misfire remained on the same cylinder. Compression and cylinder leakdown tested normal, confirming the engine is mechanically sound. Scan tool data with the engine off showed the bank 1 high-pressure fuel rail losing pressure rapidly while bank 2 held normal pressure, indicating a high-pressure fuel leak. The dealer confirmed the fault as a failed fuel injector. Inspected by manufacturer: the authorized dealer inspected the vehicle and submitted a goodwill assistance request to the manufacturer, which was declined without a stated reason. Not inspected by police or insurance. Warning signs prior to failure: none. No warning lamps, messages, drivability symptoms, or oil consumption preceded the failure. The only illuminated indicator was the low fuel level lamp, which is unrelated. The check engine light illuminated a.
Loss of power due to injectors failure on acceleration. A reproducible pattern on hwy merges or passes for example. This is an issue that has been identified and experienced by other Porsche 992/718 owners.

My 2020 Porsche 911 was two days old when I get a "ignition lock error-service required". The next day the tachometer stopped working. After the dealer fixed the problem, I drove home and park the car for two days. The next day the car would not start. I was told by the dealer this car has many problems with it's computer which makes the car unsafe because lots of its functions are computer controlled. I also just received a recall no. 19v-878.
