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 BY: 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

Both my rear break lights are showing stress cracks from movement of the frame of the body. There are other references to this happening online from other owners and it's a manufacturer defect. I brought to the dealer and was told that they should be replaced for $3000 each as they are allowing water to intrude and will cause a shorting out of the brake lights. No brake lights would be a major hazard. The cracks in both lights were not due to impacts. It is a design issue.
