What owners say
Charging system malfunctioned, sensors melted in valve trane, radiator elbow and fill neck blew off, complete engine failure and battery failure. I have had a problem with the "check brake" light and an alarm going off. However, when I stopped driving and had it towed to the dealership they could find nothing. Prior to this incident, I took a photo of my dash, I had 76,499 miles and the coolant meter did not read hot. I had had the coolant system flushed at 65,000 miles, and I had all oil and fluids checked again after this incident. The breakdown: three hours into a roadtrip, the A/C began blowing warm, simultaneously - the "the check brake" light and alarm came on, and the "check charging system" light came on. I lost power to accelerate (or brake well) and immediately pulled over and took a photo of my dash warnings (76919 miles). The heat sensor was in the "cool" half, the battery gage showed no power. Battery so low key would not start car. I had the car towed. "tech found that elbow and radiator have holes in them vehicle overheated causing engine to blow." tiffany richardson said "tech believe vehicle was driven with low coolant level causing vehicle to run hot melting sensors in the valve train and the pipes to fail." the tech is wrong, the coolant system was inspected and flushed at 65,000 miles, and was not due for another inspection. I had had coolant levels checked less than 1000 miles ago, and the heating sensor on dash did not read hot, at the point of breakdown or after a road trip 500 miles ago. Others had the problem at 3000 miles! It's the hpcu. The power for both electric motors is routed through hpcu. The inverters allow the A/C motors to be driven by d/c batteries. This caused the "check charging system" error. This is $15,000.00 and I owe $4000 on the car - 100,000 warranty has denied it & I am original owner.

Drove down the road to the store and turned off the car and when I came out to turn the car on and go home the car would not start, the issues that were happening were, the light would flicker on and off, the brake pedal was pumping in and out under my foot on its own, and the car would not start, after trying a few times the whole car and system shut down completely and the hazards started to come on automatically and there was no power to the automatic door locks and window and the only things working in the car was the anit-theft system
