On April 13, 2025, around 5:00 PM, while driving, a warning appeared on my dashboard: “Forward Collision System Reduced.” Not knowing the full meaning but understanding it could pose a safety risk, I immediately contacted the dealership the next day. I informed them it was urgent, but no one followed up. Days later, I called again and was told to bring the vehicle in. When I did, I asked about a rental vehicle (previously provided during another incident), but was told no rental would be offered until the car underwent diagnostics, which would take 3–4 business days. I explained I rely on this vehicle for work and couldn’t leave it that long without transportation. I was dismissed without any explanation of the warning. Despite reporting a system warning related to crash prevention, the dealership allowed me to continue driving. No inspection was done, and I received no help understanding the message or resolving the issue. On May 8, 2025, I missed a stop sign and collided with another vehicle. The crash caused major damage and totaled my car. The Forward Collision System never activated—no alerts, no automatic braking. The vehicle was advertised to include safety features like collision prevention that would warn or stop automatically. This failure contributed to the crash. I was cited for failing to stop and driving without insurance. I believe the system malfunctioned and that the dealership acted negligently by not inspecting the vehicle promptly. The issue has not been confirmed by the dealer because they refused to inspect it. The vehicle may still be available for inspection, and I plan to have the black box (EDR) data analyzed. No warning lights appeared before April 13.

Two weeks before the accident, a warning message appeared on my car’s dashboard stating: “FORWARD COLLISION SYSTEM REDUCED.” Naturally, I was concerned. I immediately contacted the dealership, but they failed to return my call. I followed up a few days later, and they told me to bring the car in the next day. When I went in, I explained my serious concerns. They told me they would need to keep the vehicle for 3 to 4 days just to diagnose the issue and that no courtesy car would be provided during that time. I made it clear that I rely on my car for work and had no alternative. I even pointed out that the dashboard warning was a diagnosis in itself. I asked to speak with a manager and repeated everything. He simply echoed what the advisor had said—and I was sent away with the vehicle, unresolved and still potentially unsafe. On May 8th, 2025, around 5 PM, on a clear day, I missed a stop sign and collided with another car. I firmly believe the forward collision system malfunctioned and that this accident could have been prevented had the system worked properly—or if the dealership had properly advised me not to drive the vehicle after such a critical warning. In my view, the dealership was completely negligent, and the manufacturer was aware of a defect in the system and failed to act. I also contacted the finance company, Santander Consumer USA, to alert them in case other customers have the same vehicle with the same risk. They showed no concern. It’s important to add that I did not choose this car myself. Santander limited me to specific dealerships and pre-approved vehicles. I had no freedom to select a car I truly wanted—perhaps because the available options were already considered poor choices. I believe a recall is necessary. I lost my vehicle due to this negligence, and I want to prevent this from happening to someone else. PS: I also had another message on 02/15/2025 that said: ENGINE POWER IS REDUCED, and apparently the dealership took care of it.

Noise only when cold at front tire passenger side Nosie at front tire passenger side while steering. Check engine lite code PO299 Turbocharger/supercharger underboost-engine power is reduced. Replaced tire at 24600 miles. While driving at 65 mph, the forward collision avoidance system activated, and the car stopped at 65 mph. It happened 5 times that car fully stopped, and numerus time I get forward collision activated but then nothing happens. Imagine on freeway from 65 to 0 brakes by itself. Hard shifting and body shaking while accelerating. Hood is shaking while driving on freeway.

Brakes continuously squeak and has been taken to dealer on several occasions to address but was told nothing wrong. The collision avoidance reacts to vehicles parked on side of road which has also been taken to dealer but told nothing wrong. Apple car play works intermittently.

2022 Trailblazer with approximately 21,000 miles on it. Cruise control fails to engage unless you put your foot behind the break pedal and pull the break pedal forward. This causes safety issues because a person thinks the cruise is engaged but it doesn't actually engage and causes a person to slow on the freeway. Driver also gets distracted trying to troubleshoot the issue because cruise fails to engage without an obvious reason for failure. The fix also causes the driver to operate the vehicle in an unsafe manner because they have to remove their foot from the correct position and place it behind the break pedal to fix the problem. This issue is highly reproducible and was lived with for approximately a year until the solution of pulling the break pedal towards the driver was discovered just last month. Dealer said the issue is nonexistent.

Vehicle is little over one month old and has less than two thousand (2000) miles. Adaptive Cruise has been acting erratically. At times going at highway speed on expressway adaptive cruise would apply hard brakes 1. when approaching a overhead bridge. 2. passing a vehicle in the adjacent lane and 3. changing lane. Yesterday (10/12/2022) on a higway the instrument panel displayed a warning message "Service Side Detection System". Took it to GM Dealer who ran a Diagnostic which showed the following codes: 1. B1325 Control Module Power Circuit Low Voltage 2. B317A Passenger Window Switch Short to Ground 3. U0151 Lost communication with inflatable Restraint Sensing and Diagnostic Module 4. U 0155 Lost Communication with Instrument Cluster 5. U0184 Lost Communication with Radio 6. U0232 Lost Communication with Side Object Detection Control Module - Left Dealer said that these are just notification and may not be able to find anything. It advised to bring vehicle back if this message pops up again.
