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.

Purchased new in Mar. 2013, not our first hybrid. Car began to have shudder/jerky/rough take off from morning start and first stop sign at end of street. This became more often and worsened. One morning left curb as usual, brakes locked up at stop sign and warning light on dash for brake problem. Was able to back car back into curb spot and had towed to dealership. Date given was about the towing date. Car was in shop around three weeks due to needing new brake module or something that was leaking internally inside brake unit from factory. Car also had issue to were the battery would not charge properly. Worked correctly when purchased but then would not charge past 50% and usually less than. Repairs made and lots of updates and sensor adjustments and we were given car back. Sadly it only lasted a few months and had to be towed again. Late Aug, early sept, the car started to jerk at take off again. I tried just sitting at curb for awhile after starting car to let sensors warm up. This seemed to help for short time. Problem worsened again until wife complained. I drove full time and it had gotten worse to bad and all the time. Bad acceleration, like brakes not letting off. Last straw! Nov 1st 2013, car jerked and shuddered at take off, brakes locked up solid at stop sign, locked up again at second stop sign, entering traffic to get back home . . . Car stopped dead in middle of left hand turn in middle of highway!! fully loaded log truck coming at me passenger side. Took 2-3 hard stomps on accelerator peddle to get car moving, gas engine finally revved high but car just crawled forward!!! thankfully the truck had started braking as soon as he saw car hesitate in street and car crawled forward enough that I did not get hit. But that grill filled the entire passenger window. Car towed to shop again on mon 4th am. Called on 5th, huge software update, but no guaranty !?!??.
