Tire pressure Monitor, CEL & Service Stabilitrack

What is your question?

I own a 2013 Camaro ZL1 Convertible and ver the last 2 yrs having problems with TIRE PRESSURE MONITOR-SERVICE STABILITRACK & CHECK ENGINE LIGHT going off. TPM goes off often, 20 + times & recently CEL and service stabilitrack. Had it in 3 different dealers 20 days total & they cant figure it out ?? TPMS is always left rear wheel, had the TPMS sensor replaced several times & reset . The code for check engine light is P0300, random misfire & code for service stabilitrac is U0401. 10,000 miles
