Back to the dealer!

If you mean electrical power and it came back on shortly thereafter, you may have an insecure battery terminal. Torque them up.

Re knock. Check the compartments under your rear seats. It could be your tie down cleats or something stored in there. Don’t forget to check the two compartments in the bed, right above the wheel wells for any stored objects.

Let us know what you find.

 

Check your spark plug wires. Make sure they are snug and secure at both ends.

 

Bob that is so unfortunate to hear about your taco. I have heard about shifting issues but never like this. where you have lost power, never heard of that. well i have have to research about this. eventhough i have an '05 it best to be well informed about this issue.

 

it actually sounds like your tranny is slipping with is complety crazy because you have suck low miles on it well i hope the dealership can fix your issues g/l

 

Knock coming from underneath and loss of power. Is it an automatic? That sounds like the torque converter. Have you checked your tranny fluid level?

 

Just my opinion but no knock is normal, especially from the transmission. I wouldn't let them feed you that.

 

Which dealer in so cal are you dealing with?

 

If they run you round too much take it to Tustin Toyota. My friend is the parts and service director there. They are also the number one service department in this region.

 

TC, I bought my truck at the same dealership. Talk to a salesman named "Q" maybe he can help or put some fire under the service department for help.
