Body · Engine
Severe corrosion of frame at the rear body mount location. The body of the vehicle is no longer secured to the frame at this location due to the severe rust. Significant rust also on the front cross frame member which has the tow mounts rendering them useless and unsafe. Cracked exhaust manifold causing excessive engine noise and exhaust fumes. This is a time consuming and costly repair.

The toyota secondary air system has failed rendering my car without traction control... And other lights. There is no preventative measures for this part and toyota used the exact same system on the tundra's and sequoia's with the same problem i'm having. This needs to be addressed as the repair for the system is roughly 4000.00 almost half the cost of my car... Please make them fix this on all cars where the same…

This event was clearly caused by a faulty electronic throttle control circuit. I shut off the truck. When i started it again, the situation was still there. I shut it off and waited 10 seconds, then started it and it idled normally. I concluded that there…

On the 3rd day the check engine light, vsc, and trac lights illuminated. An analysis at an independent repair shop found a computer code of p0306 (engine mis-fire on cylinder 6). A borescope video of the cylinder shows small amounts of coolant entering the cylinder, indicating a head…

Stationary on startup - my 2005 toyota has been rendered worthless because of a factory defect in the blower fan that only runs when cold starting the engine. It triggers the "limp home" mode in the vehicle which overrides transmission shifting and makes the vehicle unsafe to drive. The error code for this problem is p0418 secondary air injection system relay. This is a well-known problem and has occurred in many,…

Leaking exhaust manifolds due to faulty design this is on the v8 4runner. Exhaust will go into the cabin of the vehicle and smell like rotten eggs. Toyota will not help in the replacement of these manifolds. The charge is 2500 to replace. There is a technical service bulletin on this issue. It is hard to drive with exhaust leaking in the cab sometimes getting sick.
