Software problems of the 2015 Chevrolet Tahoe

The electrical software isn't functioning properly. The radio, onstar, the door/seat belt chimes don't work. None of the electrical works in the vehicle. I was driving and when I pressed on the brake and turning, the dome lights start to flicker making it difficult to see other cars at night. The back doors don't always lock when locking them.

Vehicle randomly loses steering control and flashes warning lights. At times, xm radio will not play. At one time, vehicle shut off and would not resart for approximately 10 seconds. Occasionally, the warning lights flash when making an adjustment like changing to bright lights or activating the turn signal. Left turn signal disengages cruise when activated. Gm has updated the software twice due to service over the above complaints. Fixes problem for short amount of time.

Upon purchase of a new 2015 Tahoe I observed the possibility of a problem with the forward collision alert system (fca). I reported this to the service manager at Chevrolet. On 9 April 2015 the service manager, assistant service manager, master technician, and I took the vehicle for a test drive. While driving the vehicle at moderate highway speeds I demonstrated the various phases and operation of vehicle detection. The fca has plenty of sensitivity and detects vehicles in excess of the specified distance in the owner¿s manual which is not an issue. At a moderate closing rate between vehicles the instrument cluster icon changes from green to amber-orange which appears nominal. However, the red alarm heads-up windshield display, rapid high-pitched beeps and red icon are never activated until a closing distance about ~3 feet before a collision. There is virtually zero reaction time for a driver to brake the vehicle at less than one car length before going to red. In addition, the system is supposed to disengage the adaptive cruise control (acc). Considering time, rate, and distance this is ineffective as the mass and kinetic energy also needs to fully disengage before a potential collision. Because of the danger of creating a traffic incident the vehicle was not tested to the level of a full collision. I was informed by the service manager that there are no service bulletins, adjustments, or software patches that may correct this deficiency by the dealer. Gm stated that the system works as designed and delivered. The gm forward collision alarm (fca) delivered product appears to have a design deficiency and is an operational safety hazard waiting to happen. If the fca does not function properly then why introduce it to a consumer regardless of gm owner manual warnings about trusting alert systems.
