Service Engine Light On Problems of Chevrolet Silverado 1500

The "service brake system" and "service esc" lights came on, along with the service engine light and rough idle, resisted roll (slight brake applied, perhaps?) and per the dealer, no code was stored and there is no fix. Bulletin pit5728b says different and not to drive the vehicle until fixed. I am refusing to accept my vehicle back until fixed as of 27 Apr 2021.

Truck was purchased certified pre-owned in June 2017, in June 2018 problems arose including rough idling, service engine light activation, and stabilitrak off message activation on the dash readout. General motors (gm) technical service bulletin (TSB) #10-06-01-008m was issued December, 2014 to address the repair for this problem. The issue was motor oil reaching the #1 and #7 cylinders thus fouling those two spark plugs. The truck was repaired under the extended warranty. The same symptoms appeared again in August 2020 and the chevy dealership diagnosed the same issue (mis-fire in the #7 cylinder) as described in the TSB. Since the vehicle was no longer under warranty, gm would not pay for the repair. I chose to deal with the symptoms myself which involved installing new spark plugs in the two cylinders. In mid-March of this year (2021), the symptoms appeared again and again the #1 and #7 spark plugs were fouled with motor oil. In each case, the vehicle was in motion when the symptoms presented. It's my understanding that stabilitrak is designed to help prevent accidents by giving the driver better control of the silverado. If a service stabilitrak warning appears, the silverado will no longer be assisted when a loss in lateral traction is detected. Additionally, the rough idling affects acceleration (loss of power. ).

Normal driving less than 10 miles. The failures are many and often. Transmission failures every few thousand miles. Always leaks trans flds all over streets and driveways. Service engine light on. Chevrolet dealer erased failure and diagnostic codes to gouge consumer, many times. Parking brake cable snapped in two on driveway. Abs failures at low speeds and engine klacks loud when starting. I am original owner of a defective 2001 Chevrolet silverado. The last time gmpp with gm dealer repair the underwarranty repairs took 6 weeks there are only 26. 000 miles on this truck. Obviously this is a defect in its design and application. (see ptior complaints) tires flew off, altering of service contracts on and on.
