Oh I never curse the master warning light, or anything else on my cars, why would I do that? Cars are interesting mechanical devices, I bought this one because I was curious about the current hybrid technology and wanted the experience of operating one. If it doesn’t start I’ll just drive one of the others.
It was much more interesting to go through various scenarios in the beginning to figure out when the Master Warning came on. There were numerous possibilities like whether or not I had parked on a hill or used the emergency brake (that was a weird Ford electrical problem I had once), or left the battery in a low charge state and only as the fall progressed into winter did the cause become apparent because I live in a fairly warm climate area.
And my local Toyota dealer? Well I took the car there soon after I first purchased it for an oil change and because it is the Gen 1 (USA, Gen 2 Japan) body style the service writer argued with me about whether or not it was a hybrid Toyota until I took him to the back of the car and showed him the car nameplate. Not too comforting but I’m not disparaging the abilities of the mechanics based on the ignorance of a service writer.
I just asked a question and certainly don’t need a lecture on how I care for my cars. It sounds like you are transportationally disadvantaged, I hope you live near a bus stop.
