Nest Protect false Co2 alarm

[Jddjr]

Came home to Co2 alarm from Nest Protect going off in garage.  I have all 3 doors wide open and it says that the Co2 is getting worse. Moved a Kidder stand alone Co2 detector into the garage and it reads 0 meaning no Co2. Is this the result of a faulty unit?

Hello Jddjr, 
I can attest to being told by Nest support that my Protect smoke alarm falsely starting was due to a faulty product, and I was directed to order a new one. I have not ordered a new one since the one I have is only a few years old. My support thread was closed out by Google while I was out of town, so am not exploring it further.  On the lookout for a more reliable product!  I hope you get better results.
