2014 TOYOTA TACOMA Engine Problems

I have had my secondary air pump replaced twice already. Now six months later am having the same codes and the truck is back at the dealership. Throws code p2443 valve stuck closed.....on a 6 month old part. This w=has been an issue with this and other toyota models since 2012. Why is there no recall on these?

I have spent 30 hours trying to find ratteling sounds from under Truck. Many have complained on Tacoma blog site with same issues. My 2014 has the 4 cylinder 2.7 engine Under 150,000 miles and less than 15 years as specified by Federal Law. I'm concerned with safety issues, exhaust emissions, engine damage and failure to drive. The sound is getting worse! Please help us with issue. JC

The contact owns a 2014 Toyota Tacoma. The contact stated that while driving at approximately 45 - 50 MPH, the vehicle stalled. The vehicle was taken to an independent mechanic and diagnosed with rod knock, valve train, and engine failure. The vehicle was not repaired and remained with the independent mechanic. The manufacturer was not made aware of the failure. The failure mileage was approximately 133,000.

SECONDARY AIR VALVE FAILURE RESULTING IN ENGINE STALL. OTHER 2013 -2014 TACOMA'S HAVE BEEN RECALLED FOR THIS SAME PROBLEM.

WHEN ATTEMPTING TO PULL OUT INTO TRAFFIC, WHEN I STEP ON THE ACCELERATOR, NOTHING HAPPENS. YOU HAVE TO PUSH THE SCCELERATOR ALMOST TO THE FLOOR BEFORE YOU GET ANY POWER. THIS IS VERY DANGEROUS, IN THAT I HAVE ALMOST BEEN BROAD SIDED NUMEROUS TIMES DUE TO THIS PROBLEM. . I HAVE REPORTED THIS PREVIOUSLY VIA REFERENCE NUMBER 10680961 BACK IN FEB OF 2015. THE NHTSA REPORT WHICH I RECEIVED WAS INCORRECT IN ITS DESCRIPTION OF THE PROBLEM. I HAVE ALSO REPORTED THIS TO TOYOTA, BIT THEY SAY THEY CANNOT DUPLICATE THE PROBLEM SO NOTHING HAS BEEN DONE. MY TRUCK NOW HAS APPROXIMATELY 24,000 MILES AND THE CONDITION HASBECOME MORE FREQUENT. I WANT TO GO ON RECORD WITH THIS COMPLAINT SO IF ANY OTHER DRIVERS ARE EXPERIENCING THIS CONDITION MAYBE TOYOTA WILL DO SOMETHING. MOST OF THE TIME I AM TRYING TO TURN INTO TRAFFIC WHEN THIS CONDISION HAPPENS.

AT COLD START UP, OIL PUMP MAKES A HIGH PITCH WHINE NOISE. DEALER SAYS ITS NORMAL DOES NOT CHECK THE ENGINE. *TR
