1 Radiator problem of the 2011 Hyundai Sonata Hybrid

Failure Date: 04/11/2017

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 "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. Airbag to.

3 Radiator problem of the 2013 Hyundai Sonata Hybrid

Failure Date: 07/19/2015

On 19 Jul 2013, an insured driver on my auto policy was driving in north dakota and hit a deer. The right fender, right headlight, hood and bumper were damaged. She called me & I told her if it was safe to drive, to continue driving. She kept driving and then the overheating light came on. She pulled the car over in less than a minute. She called me again & I told her to call Hyundai roadside assistance. The vehicle was towed to abra in bismarck, nd. They repaired the vehicle. The cost was $9760. 00. They were in the process of moving it from the repair shop to the paint shop, which was right next door. They turned on the engine & as it was sitting there, it started spewing radiator fluid. They turned it off and took the car to Hyundai of bismarck. They determined that the heads were warped and the engine was destroyed. After the cost of the new engine was added to the cost of repairs, the car was totaled. I don't think that if a person pulls over within a minute of the overheating light coming on. That it will warp the heads. The whole reason for the light is to warn the driver. . I believe that either the motor was defective or the computer within the vehicle was defective & didn't come on early enough before there was damage to the heads & was not caused by the person diriving. This insurance claim went too fast and usaa signed off and totaled the vehicle just on numbers, not on any inverstigation of the reason why the heads were warped and destroyed the engine. The 414 number is the driver. The 262 number is my number in rehab and I can be reached at any time. Very respectfully, tony.
