Radiator problems of the 2004 Chevrolet Impala

Tl-the contact owns a 2004 Chevrolet Impala. The contact stated that while driving 40 mph, there was an abnormal sound that came from the engine and the radiator overheated. The vehicle could not be taken out of park. The contact was able to maneuver the vehicle to side of the road and poured water into the radiator. The vehicle was taken independent mechanic was unable to diagnosed the failures. The manufacturer was not notified of the failure. The approximate failure mileage was unknown. Lb.

My vehicle recently started having issues with overheating. As soon as it would warm up the gauge would go the whole way past the hottest possible temp on the dash. My hot coolant temp light would come on and then I would have to pull over and turn the car off to let it cool. I took it to a mechanic who said that I would have to replace the head gaskets and intake gaskets. He researched it and said that he found that Impalas from 20003-2007 had problems with the engines because of an additive that was put in the engine. I paid him over 1000 dollars to fix the issue because before I took it to him I took it to a different mechanic who said it was the radiator so I got that fixed which cost me close to 500 dollars. So even after I got both of these problems fixed my car still overheats.

I bought car 2 yrs ago and drove it for 3 months no problems then sat for 6 months, I start driving it and this is all the stuff that went out and stuff still going on. Radiator temp sensor, water pump, heater, water pump bearing, instrument cluster, low coolant sensor, radiator, vss, key stuck in ignition, lock cylinder, 8 wires under hood shredded in half due to rubbing on belt, power lock wont work on driver side door, chimes go off when key not in ignition. My problem now is key locked up again finally got it to turn then anti theft system comes on and the car wont reprogram codes. My code reader says it cant read from car.

The traction control turns on frequently. This causes the car to make a grinding noise. When braking the car makes a grinding noise and car is not stopping it feels like it's locking up and sliding. In a sudden stop needing to be made is at great risk of a accident. I have replaced a elbow shaped part that has busted open twice. Car is constantly over heating the radiator cap has a rustic clay like substance. It won't hold antifreeze, I don't see a leak but it needs refilled quite often. The engine smokes, the cars rpm's will flex up and down and the car will just cut off. I'm wondering if the rustic clay like substance has gone through my engine and is causing me many problems with it. I have found reports of lawsuits in past regarding dexicool in gm cars doing this and ruining the engine. The problems in the reports are just like mine and many others on here. Help!!'.

Failure: lower intake gasket failed due to dexcool antifreeze. Dexcool installed at factory. Vehicle had sudden serious coolant leak . Vehicle overheated on highway and stranded owner. Vehicle was taken to dealer for service. Dealer told owner to replace gasket and coolant. Service technician replaced dexcool with another long life brand of antifreeze. The original dexcool also clogged the radiator which required extra flushing with additional chemicals.
