My coolant reservoir has been emptied suddenly on 4 occasions. One one occasion, while driving on the highways, my car overheated, and was found to have no coolant. After filling it, letting the car cool, and driving 10 minutes down the road, it had overheated and was empty again. That time, and once before, it was the hose. Another time, the cap was damaged, and was allowing coolant to evaporate. The most recent time, there is a crack in the reservoir, allowing the coolant to leak. However, my overheating warning did not come on. My heat has also not been working, even if I warm my car up ahead of time in the cold weather.

I have just over48,000 thousand miles on my 2005 chevy Aveo hatchback. The thermostat housing unit on this vehicle is made out of plastic. Over time it will wear down, and eventually crack. As a result, the engine coolant will leak out and your engine will overheat. It is not part of the power train warranty coverage and with tax the repair ran $312 dollars. This is for a design issue with using hardware with a plastic housing. The dealership knows this issue exists and that you'll have to come in for repairs eventually. Luckily I wasn't on the freeway when this happened and traveling at low enough speeds to make it home safely. I then had the car towed to the dealership for repairs. The automotive representative advised there wasn't any real way to avoid the incident with any preventive maintenance. I said it was nothing that I did with the use of the vehicle. It was a matter of timing, the summer heat conditions and the fact that the original thermostat component has a plastic housing. He stated it should not happen again as the replacement thermostat was of different construct and was no longer plastic.

Driving on the freeway uphill. No warning lights, no change in temperature. Thermostat housing broke in half at the seam. Thermostat is originally from factory, permanently encased in a plastic type housing. This is all one (1) piece. Chevy has superseded this item with a metal type housing within their ranks/computers, because it was a known issue. This item (plastic thermostat housing) knowingly splits as early as 30,000 miles. For us it was about 45,000 miles. This was never a recall item nor was any info ever sent out warning about it. Failure of this part leads to the known leaking and expelling of hazardous anti-freeze/coolant on roads but also leads to the unrealized overheating of engine. This can lead to unnecessary engine damage from simple overheating of oil to the extreme of blown head gaskets, blown/broken cylinder rings, warped engine heads or complete engine seizure. This failing part was known early enough that the new product had already been made and distributed to dealerships. Web logs are full of this particular failure, on this vehicle. 3 days after repair, the car has a "slow start", as long as 15 min. The dealer kept it 2 days, replaced plugs & wires, charged $400. 3 days after this (10/13/08), same exact problem, in addition hold light will stay on & car shakes as if not getting fuel. I must turn off the engine and attempt to restart. The dealer has informed me unless the actual problem is occurring they cannot diagnose. Today (10/16/08) after a slow start, the a/c worked for about 10 min then started blowing hot air. Turned it off for a couple of minutes and it proceeded with cool air. This happened twice.
