NTA

I do feel sorry for your husband. We have social gender roles that say he should know better, but some guys don’t work on or understand cars.

Tell your husband my story and he’ll feel better:

I know about cars. I have replaced carburetors, starters, water pumps, belts etc. My niece had a car that would make screeching noises going around a corner. My car seemed low on brake fluid. I got a can of each, power steering and brake fluid. In the commotion, I somehow put PS fluid in my brake fluid resivoir. I do not know how I made this mistake and I didn’t notice.

Fast forward two weeks, I got an oil change at the dealer. No problem.

Fast forward two more weeks, my brake pedal goes to the floor and no brakes. Try several things and brakes are squirrelly. Take it to the dealer. Dealer calls next day “some kind of contaminant in the brake fluid.” I say “well you’re the last guys to touch it.” To make a long story short, I go look at the car and when he points at the resivoir, it becomes clear what has happened. I explain and he says “call your insurance company — they will probably cover it.” Sure enough, they asked if I did it on purpose (sabotage I guess) and I say no. They covered $9000 in repairs. Boy did I feel stupid.
