Engine overheating by model year
What owners say
Failure of thermostat housing causing coolant leak and water pump failure.
Failed thermostat housing/coolant loss. Active coolant leak from water pump/thermostat housing at 35,956 miles. Dealer replaced thermostat assembly, water pump, union.
Engine thermostat and pump failure with gradual coolant leak. Coolant required refilling multiple times within 45,000 miles, sometimes coolant getting dangerously low without warning until car is on interstate. Thermostat/pump has also begun overcooling engine, not allowing it to get up to operating temp when on interstate and shutting out usage of cruise control. This is a well known and documented issue with mk7 gti.
My thermostat had a coolant leak at 37k, and this was diagnosed at the vw dealership in 12/20. My vehicle has never been in an accident, and has been meticulously maintained at the vw dealership. Upon doing some research, it looks like this issue is quite common on 2015-2018 vw gtis (and it looks like in addition to the thermostat, the water pump is often prone to leakage) and this problem has been documented on vw forums here: https://www.reddit.com/r/golfgti/comments/drna5m/mk775_thermostat_housing_issue_and_coolant_loss and here: https://www.golfmk7.com/forums/index.php?threads/failed-thermostat-housing-coolant-loss-info-gathering.368847 the thermostat should not be leaking so early in the life of a vehicle. This leak can lead to a loss of coolant, which in turn can damage or destroy the engine. I contacted vw of america, and they declined to cover it, as the vehicle was just out of warranty. It looks like this is potentially a defective part that can lead to the vehicle not working, and I would hope that a recall would help other owners protect their vehicles.
Thermostat housing seal failure has LED to coolant leak. Discovered by technician during unrelated maintenance. Car has 76,000 miles.
