About a year ago I brought my car to the dealership because my computer blacked out which resulted in losing power steering and braking ability. I was told they hooked it up to the computer and found nothing and sent me on my way. Last week this same thing happened 5x in one day and I lost all computer function for 24 hours. The computer has since glitched and blacked out multiple times but have not lost steering or braking.

Component Affected: POWER TRAIN: AUTOMATIC TRANSMISSION / TRANSMISSION CONTROL MODULEDescription of Safety Defect:The vehicle is experiencing a severe, intermittent, and violent mechanical "garage shift" engagement lurch. This occurs specifically when shifting the gear selector from Reverse to Drive during a cold-start cycle.When the gear is selected, there is a distinct hydraulic delay followed by a violent mechanical slam that causes the entire vehicle to violently lurch forward. This unintended vehicle movement occurs even though the engine has naturally idled down completely below 1,000 RPM, and while the brake pedal is fully and firmly depressed to the floor.Safety Hazard and Consequences:This defect poses an immediate and severe safety hazard. The mechanical force of the lurch is strong enough to potentially overcome the vehicle's braking system or cause a foot-slip off the pedal, resulting in sudden, unintended vehicle movement. This creates a high risk of a low-speed collision, vehicle damage, or striking a pedestrian or property during tight parking or garage maneuvers. General Motors' internal service bulletins (such as Bulletin 24-NA-009) indicate known issues with sticking clutch regulator valves or solenoid over-travel causing line pressure spikes in these modern transmissions, yet no safety recall has been issued to permanently address this dangerous powertrain defect.

Rear back up camera. One day it started to glitch when put in reverse. I placed the car in park, gave it a moment and put it in reverse again. This was repeated in the attempt to get the back up camera to work. Next- turned the vehicle off for a moment, restarted it, put in reverse and this did not help. Also, I attempted to check for update/update and reset the infotainment system. This did not help. The backup camera, after this incident has not worked since. I bought this car brand new. Also, just to note, the car shakes dramatically when increasing certain speed during winter, due to very little snow on the tires.

The vehicle has experienced ongoing and unresolved issues despite multiple service visits. The primary concern is excessive engine vibration. It shakes concerningly when backed into a driveway at an incline and placed in park. This occurs while the vehicle is stationary and idling. The issue has been reproduced and acknowledged by a dealership service advisor during a test drive, who stated the vibration was excessive and concerning. However, no repair was completed, and no clear diagnosis has been provided. The vehicle has also displayed repeated error messages with no confirmed cause, ongoing Bluetooth connectivity issues even after system updates and resets, and a malfunctioning forward collision warning system. Prior repair attempts include replacement of the backup camera, center console, and exterior windshield trim. The windshield trim repair was incomplete, as only the middle section was replaced while the remaining components were not, resulting in a mismatched and unresolved condition. No service documentation was provided for the most recent visit despite being advised that updated findings would be sent. These issues have persisted across multiple service attempts and remain unresolved. The engine vibration and malfunctioning safety systems raise safety and reliability concerns, including the potential for reduced driver awareness and increased risk of a collision.

The incident involved a 2025 Chevrolet Trailblazer, purchased new in late February 2025. The failure appears related to the vehicle’s electrical/charging system and associated control modules, resulting in a sudden loss of critical safety systems. The vehicle was towed by GM Roadside Assistance and is currently at an authorized Chevrolet dealership, where it is available for inspection upon request. While driving in Cambria, New York, the dashboard illuminated with multiple warning indicators and the vehicle experienced a complete loss of power steering and braking. The brake pedal traveled fully to the floor with no resistance and no braking effect. Steering effort increased dramatically. The driver was only able to avoid a crash due to favorable road and traffic conditions and was able to coast to a stop and pull off the roadway. This failure posed an immediate and serious risk of injury or death to the driver and others. The problem had occurred previously in the form of repeated warning messages. Beginning within the first week of ownership, the vehicle displayed “Service the Charge System Vehicle May Stall” warnings and since then has appeared hundreds of times. The vehicle was previously towed to an authorized Chevrolet dealership, where we were informed that General Motors identified the issue as a known software-related problem and advised that the vehicle could continue to be driven while awaiting a future update. The catastrophic failure occurred after this guidance. The vehicle has been inspected by an authorized Chevrolet dealership both prior to and following this incident, and General Motors has been involved through dealership communication. No police or insurance inspection has occurred, as no collision resulted. Based on the repeated warnings, dealer statements, and nature of the failure, the best assessment is an electrical or software-related malfunction, though the precise root cause remains UNKNOWN and requires investigation.
