I get the NAPA gold ones. They're a reboxed stant superstat and I've never had that product line give me a dud.
Pros: never a dud, reliable

Just so happens my clearance thermostat is a Motorad which has the VW/Audi p/n cast on the housing!
Pros: VW/Audi part number
Vehicle:

I always use Premium Thermostats, which are billed to fail open. Gates or Stant are my favorite brands.
Pros: fail open
Make sure you get an OEM thermostat from the dealer. These engines use a cold side thermostat. so if you get one from a parts store, it’ll be wrong and still run hot. It stays right at 190 now cruising on the highway empty. Before, it was always at 220.
Pros: stays at 190F, correct type

My Q5 with 75,000 miles on it developed a leak in the water pump area. Initially Audi denied there was a leak, so I took pictures and showed it to them. Then they diagnosed it with thermostat leak.
Pros: warranty on that part
Cons: leak in water pump
Vehicle:
Audi Q5
Mileage: 75000 km
Aisin THF-003 thermostat was used (I believe this is what I'm regretting). It's like the thermostat isn't opening? Everything else seems fine - it's clearly getting hot. Little to no heat at idle. No circulation = overheating of the engine. Is the replacement thermostat stuck shut?
Cons: thermostat not opening, overheating engine, little to no heat
Vehicle:
Subaru Impreza
Part number: THF-003
Installed a Motorad thermostat and noticed the temp gauge dropping on the highway. I never had this issue before I changed the tstat
Cons: temp gauge dropping
Our 2022 CX-5 Premium Plus (non turbo) is going in for its 3rd thermostat replacement next week. Each time it’s been replaced at Mazda under warranty with an OEM part. Vehicle will hit 90,000 Miles this month. Does this thermostat wear seem excessive or is it normal for these? Bought brand new and it’s been the only problem, other then general maintenance
Cons: repeated failures, excessive wear
Vehicle:
Mazda
Mileage: 144841 km
