Thermostat Recall

Does anybody have info on this? I called the dealer (in Canada) and my VIN has a thermostat recall listed against it. They didn't have the part when I brought my car in for its first servicing this past weekend, so I haven't done the replacement yet.

Anybody know what this would affect?

Well, if its defective and remains shut, you get overheating and possibly blown engine at worse. Or nothing will happen till it gets replaced at best. I will get it replaced asap though. Watch you temp gauge until then.

Certain 2017MY Elantra vehicles may exhibit an illuminated Malfunction Indicator Lamp (MIL) with the
following diagnostic trouble code(s):
 P0128 : Coolant Thermostat (Coolant Thermostat below thermostat regulating temperature)
This condition may be cause by the rubber valve inside the thermostat not closing properly. This
bulletin provides the procedure to replace the thermostat assembly to correct this condition.
Thermostats must be replaced on all affected vehicles, even if they do not exhibit DTC P0128.
Should the thermostat be defective, it will be stuck open rather than stuck closed. So there is no risk of engine overheating. The engine will take longer to reach normal temperature.

That's what I was thinking. My second thought was > why aren't you posting more often? Lurking isn't cool, man! I'm kidding.

Don't know anything about Hyundai's yet, but do know a couple of things about thermostats. Are you saying Hyundai is incorporating a fail safe thermostat?

Typical are waxed filled into bellows that expands against a very strong closing spring, if that wax leaks out, thermostat stays closed, not good. Fail safe had a secondary device that releases all the spring pressure leaving the thermostat open, least the head won't crack. But depending on ambient temperature, may always stay in open loop mode where the AF ratio may be running lean or rich with much longer detrimental effects.

A new electronically controlled thermostat decreases pumping energy and allows the thermostat to open at a higher temperature.

Original O2 sensor just contained the zirconia element that was worthless until the temperature exceeded 350*F, even though it had 1200-1500 degrees exhaust gas temperature, added about a dimes worth of a nichrome heater coil to it to get into closed loop faster that doubled the price of this O2 sensor. Course if the heater element burnt open, would get a code and you were out around 60 bucks.

GM came out with a so-called electronically controlled thermostat, are they using a servo motor? No, just the same hundred year old wax filled thermostat with a 20 watt heater element added to it. When you hit the gas, would apply a voltage to this heater element in a very weak attempt to fool the thermostat into thinking the coolant was hotter so it would open this valve a tad bit quicker to handle the additional heat load when pouring more gas into the engine. But still was not a fail safe thermostat, but adding this heater element, price tag was more than tripled. More BS from the automotive manufactures to screw the consumer even more!

Closest thing I can find for an Elantra 2.0L thermostat is this one from a 2014 model.



Sure looks conventional to me, so exactly what is the 2017 model using? And is it really electronically controlled? What appears to be a thermostat housing is directly under the alternator on my 2017 Elantra 2.0L engine, sure don't see any wires going to it, and my x-ray vision is poor this morning so can't see what's inside of it. But this is Hyundai's worry, not mine.

Sure living in a world with BS, in central Wisconsin even on New Year's day, can get winds from the SW with temperatures in the 60's, but still only can get this stupid winter gas and terrible fuel economy with it. Heavily oxygenated to supposedly decrease the warm up time to ease emissions, but with zero proof on this. EPA does not have to provide any proof. Fuel economy can drop as much as 25%, but the price at the pumps is still the same if not even more than summer gas. With my Cruze, instead of getting 40 mpg, more like 30 mpg. Will find very quickly how the Elantra does.

This months SAE Engineering is on cutting green house gases with opinions from the experts. Really doesn't take any brains to solve this, just reduce the carbon, low heating value, gums up the engine, and fouls spark plugs. Like a 125 year old problem. Crap in, crap out.

I doubt that any car manufacturer uses fail safe thermostat as oem part.

Those fail safe stat by motorad seems to give more trouble than benefit. Good idea, but seems to fail more often than the regular one. I use the regular ones.

hrmmm.. I just checked Transport Canadas website, and nothing about the thermostat there. There is a recall for airbags for FOUR cars though. Is there another area I can search for recalls?
