About These NHTSA Complaints:
The NHTSA is the US gov't agency tasked with vehicle safety. Complaints can be spread across multiple & redundant categories, & are not organized by problem. See the Back button — blue bar at the very top of the page — to explore more.
This vehicle is equipped with an all wheel drive system, which is necessary in our environment to climb icy or muddy hills to get to our house, or friends' houses, all on dirt roads. It's also very beneficial for driving on icy and slushy roads which are frequent around here. We have three vehicles, all AWD or 4WD. On the 2005 Pontiac Montana SV6, however, there appears to be a sensor on each wheel which is integral to the AWD system. This sensor is apparently easily obscured by ice, slush, or mud splashing up into the wheel wells, and when this happens the vehicle disables its all-wheel drive system, leaving the driver with a fwd vehicle, which can often be insufficient to handle conditions entered with an AWD vehicle. So far we've been stranded at the bottom of icy hills and narrowly averted two crash incidents due to the AWD system disabling when driving through slush puddles or mud. The dealer has been able to clear the sensor and reset the system twice - on the third incident we were told the entire right front hub assembly would have to be replaced, so apparently slush can permanently damage the AWD system as well. This problem was reported to Pontiac via their website and they haven't bothered to respond.
