Replacing the HD mounts with OEM mounts definitely seem to have solved the problem as I haven't heard any noises in years.

Those tanks are cheap and very easy to replace, also if you don't get a lot of air in your system they work just fine. So slap a new one in there and no worries.
Yes, replacing the expansion tank corrected my issue. Leaking or venting from that tank is not normal, if the system builds up to much pressure it should release from the pressure cap.
Just turned 30K on my 18 SE 4 MO, oil changes at dealership every 10K and just replaced the rear brake pads myself. That's it - has been a reliable, comfortable car with a great size to mpg ratio.
EDIT: SOLVED - noticed no leakage around thermostat, coolant ball, all belts were dry, and upper radiator dry. In the end it was the radiator.
Stock rotors are cheap and effective anything bigger is just for show.
I have a 2018 Tiguan and it started having the same issues every so often, then suddenly on the highway it went into limp mode restricting the engine to 4K rpm... turns out two cylinders weren\u2019t receiving fuel so those two injectors had to be swapped... under warranty thankfully!
I think the single largest shortcoming is the tires. After that, probably the suspension. After I owned it for about 6 months I noticed that driving over potholes and speedbumps was not nearly as good as I was expecting out of a lifted car.
mine is also a problem an my car is 1.5 yrs old. Sometimes the temp gauge acts as if it is -40C outside even if it is a couple degrees above freezing. Often the car will take 4-5minutes to get near base idle when it is cool outside, but when it's really cold, sometimes it takes 30seconds and there is no way it's warmed up. Can also smell coolant anytime I open the hood. Sad.
I had my water pump and thermostat changed in August under warranty. I went for an oil change in Dec and they told me they think the thermostat is leaking. I told them they just replaced it 4 months ago. They went back and cleaned up the area around the thermostat and oil pan and said we need to monitor it to see if it's really leaking again. They were not surprised when I asked if it was possible it could be leaking again. They told me they see the part fail all the time.
