Shortly after the engine replacement, the transmission began exhibiting unusual shifting behavior. The dealership advised that the transmission needed to reset or relearn its shifting patterns. However, approximately 10,000 miles later, the problems have continued and become increasingly concerning.The vehicle now shifts extremely hard when engaging Drive or Reverse and experiences harsh, abrupt shifts while driving. More concerning, the rear wheels have appeared to lock up unexpectedly on multiple occasions at low speeds, creating a dangerous situation where the driver could lose control of the vehicle or be struck by another vehicle.  I reported these problems to the Chevrolet dealership, but I was informed that they could not reproduce the issue or identify any diagnostic trouble codes. Despite these serious symptoms, the underlying problem remains unresolved. I am concerned that this may be a transmission, torque converter, transmission control module, or drivetrain defect affecting other GM vehicles equipped with similar powertrains. I am requesting that NHTSA investigate these potentially dangerous failures, particularly the unexpected drivetrain locking and severe transmission engagement issues, before they result in a serious accident or injury.","products":[{"type":"Vehicle","productYear":"2023","productMake":"CHEVROLET","productModel":"SUBURBAN","manufacturer":"General Motors, LLC"}]}]}
