Thermo control valve (TCV)…
Thermo control valve (TCV) failed at 60,501 miles on my 2021Outback, just past the 60k mile drive train warranty. I ALWAYS buy extended warranty (Yaris, Camry, Outback since 2011) on used cars. Parts cost $650 (valve is $430) + 5 hours labor. Subaru redesigned this faulty design in mid 2021, but not recalled the vehicles with this bad valve. The intake manifold gasket is back ordered by 3-5 weeks. My dealer has replaced 10 of these valves in the past 3 weeks! In my case, the valve is open allowing constant flow of coolant which keeps engine cool/cold. Little heat and temp gauge is shut off. This failure turns off Eye-sight, cruise control, lane assist, pre collision braking and more while showing at least 4 dash lights. Other cases might have car overheating, but dealer strongly suggests I do not continue driving. Luckily I still have my older Camry. Not sure if ext. warranty covers car rental but dealer does not have a loaner car to give me. In addition, my battery failed 2 weeks after buying this Outback. Replaced with a $368 750 CCA battery. I plan to sell this Out ack well before my ext warranty expires at 100k miles. Will go back to most reliable Toyota. PS. this valve in newer cars provides much more precise temp. control, cars heat up faster & gain about 4% fuel efficiency.
