“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.”

“The contact owns a 2013 Chevrolet Sonic. The contact stated that upon turning off the vehicle, the ignition key remained stuck in the ignition switch. Additionally, the contact noticed that the gear shift indicator was indicating that the transmission was in park(P) and in drive(D) simultaneously. The contact stated that upon moving the gear shifter in and out of park(P) several times, and shifting back to park(P), the contact was able to release the key. The contact stated that the failure had recurred several times. The vehicle was taken to the dealer, where the gear shifter was replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 126,419.”

“On 7-27-2023 General Motors issued a recall on 2013 models of Sonic, my VIN was not included in this recall. However on 4-16-2025 my sonic was involved in a impact incident in which the air bags should have deployed, and did not. It is my opinion that Chevy, knowing of the issues with the model of car, should have issued a recall for my vehicle as well, but did not. As a result I suffered additional strain and injury during my impact as no airbags deployed.”
