Recently bought a 2019 Tundra SR5 long bed, but before I bought it had the dealer do the 36k mile warranty check. Clean bill of health, so bought it. Embarrassing to admit this, but these days had to pay more than it cost new. I’ve owned many Toyota’s so thought hey this will last me forever, so no big deal. As winter started setting in, up here in Alaska, I turned the heater on and discovered that just air was blowing out and not warm. Switched to AC and discovered that while air would blow out, it was not cold. Set up an appointment at the dealer in town and waited 2 months for that. Dealer analyzed it and told me the HVAC unit is bad. Estimated 14 hrs of work tearing the whole dash apart to replace it and gave me an estimate of $4,000. Vehicle is at 38,000 miles and just over the 3 yrs of warranty. I have to say, I’m a bit shocked. Shouldn’t an HVAC unit last for the life of the vehicle? Have I just bought a lemon? Anybody else have an HVAC problem with a relatively new Tundra HVAC unit?
