Corolla LE ECO 1.8L 4 cyl

  • CVT transmission
  • 81,000 miles

I bought this car at a dealer in Columbus Ohio and didn’t notice the defog not working. Took to Grahms Toyota in Mansfield, Ohio. First time they told me it would cost $140 to evaluate the problem, which I paid. Then they told me it would cost $380 to fix it. So I paid that. Then when I picked up car the defrost still didn’t work.”I live in Ohio where we need defrost, it’s critical “. So I took it back.

They re-evaluated the problem and said it would cost $4000 dollars to fix....the heater box needs replaced because a part inside the heater box is broken. This part controls the flaps which open and close passages where to send the air. Supposedly the reason it cost so much is Toyota put every part in system in a sealed box.

Evidently Toyota is trying to make people buy their parts only. Because you can’t purchase nowhere but Toyota and it cost a fortune. Now my problem is it is out of warranty, but should a one year old cars heater break in less than a year?

I called Toyota to see if they could assist me? They said the car is out of warranty and they will not be responsible. I wanted to try Toyota for first time but they left a very bad taste in my mouth,not purchasing another Toyota ever. Now car transmission has a shutter at 20 miles per hour.

Corolla 1.8L

  • Automatic transmission
  • 2,025 miles

this 2017 toyota corolla has automatic temperature control. when using the heater system on re-circulated air and you have the temperature set to what you like the heater system will change over on its own to the cold outside air. and when it will not go back to using the recirculated air. you have to push the recirculated air button to stay warm. you should NOT have to do this!! brent brown toyota dealer in utah gave me a bunch of what I call double talk. they said that is the way the car is made!! and there is no way to fix the HEATER PROBLEM. I asked BRENT BROWN TOYOTA DEALERSHIP IN UTAH if they could re program the PCM OR THE ECM that control the heater system. again I was told in so many words that THAT'S THE WAY IT IS!! now I have to tell you that MY WIFE DOES NOT LIKE THIS EITHER!! we have 2 2017 toyota corollas that we HATE TO DRIVE!! so now we have 2 toyota corollas that just sit in the garage and get dusty. we paid cash for both of our cars. so now we have over 45,000 dollars in 2 cars that WE HATE TO DRIVE!! I sure hope to HELL that they find a FIX for the HEATER PROBLEMS. oh by the way every time that you re start the car YOU HAVE TO PUSH THE RECIRCULATED AIR BUTTON OR THE SYSTEM WILL STAY ON THE COLD COLD OUTSIDE AIR.
