I am filing a complaint regarding ongoing and worsening issues with my Chevrolet vehicle, which appear to point to broader defects involving the engine and electrical systems. Months ago, while driving, the car suddenly lost power and displayed ‘Engine Power Reduced.’ I had to keep using it due to work needs. Over time, it hesitated more during acceleration and felt increasingly unsafe. When I finally brought it to a Chevrolet service center, I was told the issue involved the pistons. The vehicle also regularly shows a ‘Shift to Park’ warning even when the gear is in Park, raising concerns about the transmission’s reliability. The power loss continues, especially when going uphill a” again triggering the ‘Engine Power Reduced’ alert and dropping the speed to no more than 35 MPH. A diagnostic showed a P0302 code for a cylinder 2 misfire. The radio head unit, already replaced once under warranty, failed again after just 9 months. Prior to the worsening idle and gear issues, I also received network-related codes involving the ECM and transmission computers. Although Iave replaced the alternator, the car still shows ‘Service Electric System’ warnings, suggesting ongoing electrical problems. I also noticed GMas N182195660 campaign involving predictive monitoring for Stochastic Pre-Ignition (SPI) on SCP platforms. My car has the 2.0L turbo engine, and Iam concerned it may be experiencing SPI or coolant intrusion issues affecting overall performance and system integrity. Iam requesting that Chevrolet investigate these problems thoroughly and determine whether my vehicle qualifies for recall, extended warranty, or defect coverage. These issues are persistent, serious, and deserve immediate attention. Thank you for your time. I hope to see resolution soon.
