I had a head gasket replaced due to overheating this past week at a Toyota dealer.
The head gasket was on recall and they replaced it for free.
They also put on the engine new spark plugs and a new thermostat and a new gasket on the exhaust manifold as well.
I have driven it home now and there is an obvious electrical surge /shortage somewhere because it jolted down the road just now and stopped and when I opened the hood there was smoke coming from the cable going to the negative terminal.
They maybe didnt ground the wire back when they put everything back together????
I am a landscaper and needed to mow my customers lawns today and will be losing money by not being able to use my truck.
What will Toyota do about it????
Thanks for your answers!
