Dear Sir, On April 2026, I need to do the semiannual smog check. Right now, I face DTC P0420 error code and I can't pass the smog check inspection. Note that I don't have the engine light on indicating the a/m error code. Only my OBD2 shows the error DTC Code P0420. I did some searhing and noticed that the ECM for Sienna should be updated to erase the a/m DTC code. I would appreciated to help me how the resolve this issue ASAP. It will enable me to renew my registration.You may contact on my cell phone 747 217 7254 or my email at massey.miri@gmail.com. Regards, Massey

THE LOWER REAR MOUNT FOR THE PASSENGER-SIDE REAR SHOCK ABSORBER WAS FOUND WHEN THE VEHICLE WAS STATIONARY TO HAVE BECOME PARTIALLY FRACTURED OVER TIME. IT IS MADE OF THIN HOLLOW METAL WITH INTERNAL THREADS. THERE IS NO REPLACEMENT FOR THIS EXCEPT TO PURCHASE A LARGE MULTI-FUNCTIONAL UNIT COSTING $1,688.00

BRAKES MAKE A NOISE WHEN THE CAR IS ABOUT TO STOP. THERE IS A SQUEAL AND THUMP THAT CAN BE HEARD. HAVE TAKEN THIS IN SEVERAL TIMES TO BE FIXED. THEY SAY THE BRAKES ARE SAFE. I AM 74 YEARS OLD AND HAVE HAD MANY CARS OVER THE YEARS AND THE ONLY TIMES OTHER CARS HAVE MADE THIS KIND OF NOISE IT WAS TIME TO CHANGE THE BRAKES. IN THIS CASE THE BRAKE PADS SEEM TO HAVE PLENTY OF LIFE LEFT. FUNNY THAT WHEN THE REAR DRUMS ARE REMOVED AND THE BRAKE AND DRUMS ARE THOROUGHLY CLEANED THE NOISE DOES NOT HAPPEN FOR A WHILE. THE FIRST COMPLAINT WAS MADE AT 15,523 MILES AND CONTINUES TOO THIS DAY. AT 31,842 MILES THE REAR DRUMS WERE REPLACED PER TSB BR003-04. TOOK THE CAR IN AGAIN AT 125,559 MILES AND WE WERE TOLD WE NEEDED NEW REAR DRUMS. THEY HAD BEEN REPLACED. THEY HAVE A PROBLEM WITH BRAKES AND NEED TO FIX THE PROBLEM.
