Open the full vehicle complaint log (all categories)The DC to DC converter for the Hybrid 48v Electrical system has failed. This puts the vehicle at risk of a fire. The part is backordered for a significant amount of time, and there are many others in this situation.
While I was driving, the vehicle shut down unexpectedly. I was sliding sideways across the road on ice on the side of a cliff and luckily was able to stop the vehicle before going off the side of the mountain. I had to entirely restart the vehicle to begin driving again.
Engine light came on while at a stop light, engine faltered completely and car stalled. Would not restart. Shifted car into Park and tried multiple times to restart, finally got it restarted. Rolled forward per the flow of traffic and engine died again in the middle of the intersection putting me directly in harm’s way. Multiple lights including engine light and dash warnings appeared. Pictures attached. This is a major safety issue, the car died and I could not move it forward. I was almost hit and could not get the car restarted, not once but twice. I have owned the car for less than one week, and it’s been back in the shop now twice. The first time ( Wednesday) was also for electrical issues, including sensor issues.
WHILE DRIVING MY VEHICLE AT HIGH SPEEDS ON AN INTERSTATE, THE BATTERY WARNING LIGHT ACTIVATED. BEFORE I WAS ABLE TO PULL THE VEHICLE OVER THE AIR CONDITIONER I'LL PROBABLY BEGIN TO STOP WORKING. FOLLOWING THIS, A SERIES OF MULTIPLE WARNING LIGHTS ACTIVATED. THE VEHICLE WOULD NOT ACCELERATE AND I WAS FORCED TO PULL OVER. FOLLOWING THIS, THE VEHICLE WOULD NOT ACTIVATE WHATSOEVER. ALL POWER WAS LOST. I COULD NOT SHIFT GEAR. THE CAR REQUIRED A TOW TO THE LOCAL DEALERSHIP.
