Dear GM Executive Office, I am writing in frustration and disappointment after being told today by Chevrolet Customer Assistance that the case I opened (Case # [XXX]) was simply a "dealer complaint" and that no further help would be offered - despite my vehicle exhibiting a recurring, safety-related malfunction covered under Special Coverage N232395330 - Turbocharger Replacement. To Whom It May Concern, I am writing to formally request a resolution regarding a recurring and unresolved issue with my son’s 2018 Chevrolet Sonic Premier (Turbocharged engine), VIN: [XXX] This past January we brought the vehicle to Ziegler Buick GMC of Lincolnwood an authorized due to overheating and a warning light. We paid $210 for a diagnosis and an additional $520 for a repair, totaling $730. The only action taken was the replacement of the coolant reservoir. The issue was not fully diagnosed, and the root cause was not addressed. On [XXX], the same issue has returned: Red heat warning light illuminated after less than one mile of driving. Coolant reservoir nearly empty upon inspection. Engine went into reduced power (“limp mode”). Scanner showed only a low coolant level but no additional actionable codes. Vehicle also displayed a change oil warning, likely triggered by overheating. This vehicle has a known history of turbocharger and coolant system defects, which have been acknowledged in GM technical service bulletins and Customer Satisfaction Programs. I have reason to believe this situation qualifies for one of those programs. Despite paying $730 for a prior repair, the vehicle is now exhibiting the same safety-related malfunction, putting my son at risk of engine damage and breakdown. We have also taken the car to Mike Anderson Chevrolet twice for inspection and they reported finding nothing. I am respectfully requesting the following: A thorough inspection and diagnosis of the entire cooling system and turbocharger INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOI

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.

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.

UNKNOWN. Our car caught fire but I'm not sure what actually caused it, it was in perfect working condition before. I saw articles online saying there was a voluntary recall due to faulty welding in the fuel tank so it could be that. I believe it's a dangerous defect and should be an official recall. My family and I almost lost our lives because of it

Factory Radio. It will turn on and there is sound, but the screen is frozen. You can see everything on the screen, but if you press something on there it doesn’t do anything. Also, you can’t control it from the steering wheel either. I already removed the battery cables for 30 minutes and that didn’t correct the issue. It’s my opinion that the radio needs a software update. I have seen where other Chevy Sonic models and different years have had this exact issue with the radio, because you recalled and fixed them. This issue needs to be corrected.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The passenger seat adjustment mechanism has failed, causing the seat to become stuck in the farthest rear position. The malfunction is likely related to either the motor, seat track, or the electrical system controlling the adjustment. The seat is available for inspection. 2. How was your safety or the safety of others put at risk? The stuck seat presents a safety hazard because it is positioned too far back, which can prevent proper seating posture or seatbelt positioning for a passenger. This could increase the risk of injury in the event of a crash, as the passenger may not be secured properly or may be too far from the airbag deployment zone. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue has been confirmed by both an independent mechanic and two other individuals knowledgeable about cars. The problem has been physically inspected, and the seat remains stuck in the rear position despite attempts to adjust it. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? No, the vehicle has not been inspected by the manufacturer, police, or insurance representatives yet. However, it has been looked at by independent service providers, who have confirmed the issue with the passenger seat. My car is no longer secure by the bumper-to-bumper warranty despite only having 52K millage. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, messages, or other symptoms prior to the failure. The issue with the seat adjustment occurred suddenly, with no prior indication that there was a problem.
