Vehicle enters into catalyst monitor too early. Monitor Fales indicating that the catalyst is below efficiency threshold. A vehicle is run for a significant amount of time before being allowed to enter the driving conditions for the catalyst monitor, monitor will pass. This indicates that there is a programming failure, not an actual component failure. Theory has been tested multiple times. Catalyst had also been tested by temperature sensor as well as by taking readings with a gas analyzer before and after the catalyst. Everything indicates the catalyst is well within operating parameters. Theories, test, and confirmations have been conducted by a certified technician and mechanical engineer.

Multiple parts in my engine have malfunctioned in the past year, the most recent being a tube bursting and getting coolant everywhere. Other problems have been with valves, temperature gauges and even the radiator. It's like something new breaks every month. I have had every issue fixed and usually I don't get a warning lamp until I'm broken down on the side of the road.
Boniface hiers Chevrolet dealer in Melbourne Florida said they did a full inspection before selling this vehicle. 2 days later after purchase the Radiator fan stop working even tho they put a new one, missing thermostat, code 3rd gear malfunction.
Was driving in heavy rain when car suddenly cut power and decelerated showed code 84 and the CEL came back with P2138. It is a known issue that rain gets up into the connector and causes a malfunction.
Things started after my vehicle was repaired after a car hit me and took off. I noticed the check engine light came and stayed on, at certain times the car either while driving or while stopped the car will either shake for 2-3 minutes or also while stationary the traction system light will come on then turn off. I've also experienced issues with slow or not as responsive acceleration or unprompted rpg gauge revving and sometimes thats coupled with the shaking to the point that my has shut off while driving down a city street. I was never aware of any recalls so im not sure if it has anything to do with a possible recall that hasnt been diagnosed but theres great cause for concern. - sn: I wasnt able to choose every affected part.
