I had the same problems with
I had the same problems with my 2005 Tacoma after the frame replacement. The brakes went to the floor and the steering shaft was loose. Definite safety issues that they obviously didn't catch with a test drive! 5-months later noticed the 4WD didn't work. They found a damaged connector that "had nothing to do with the frame replacement", but they fixed it for me. The day I picked-up the truck I heard a gurgling noise coming from the cooling system. I know they had to drain the cooling system and figured that the air was totally removed from the system and that it would eventually stop. That did not happen and my check engine light began to intermittently light. Found out it was a misfire on the cylinder #4, a P304 error code. Replaced the plugs, a coil, and tried swapping the coil around but the problem stayed with the cyl. #4. Had diagnostics done at a Lexus dealership yesterday and found out the head gasket is leaking antifreeze into the cylinder. This was most likely caused by an air pocket in that area of the cylinder head that caused it to overheat there. The system was not properly burped along with all the other issues I had when I picked it up. Now I have to fight with Carlson Toyota of Minnesota again to pay for the costly, $3,000, repair caused by their lack of a proper test drive and diagnostics.This will probably be my first & last Toyota product that I buy.
