2006 Pontiac Grand Prix: engine overheating

Filed Jan 27, 2020 · Electrical, Lights · 134,000 miles · MI

My 2006 pontiac grand prix experiences headlamps turning off without warning while the vehicle is in motion, and not being able to get them to turn back on again. I drive country roads home from work at night where there are no streetlights and the speed limit is 45-50 MPH. This is a serious safety hazard ! ! ! It is socially irresponsible for gm to ignore this issue. For some reason 2006 pontiac grand prix is not part of gms product safety recall (recall number: 14291 which only replaces the headlamp driver module hdm fuse). I have had to replace the hdm relay twice already, which only lasts for about 4 months before burning out again. Obviously the problem is not just with the fuse but likely with the electrical wiring or the fuse box itself. This serious problem must be investigated more thoroughly before somebody is killed. I did read that 2006 pontiac grand prix was offered an extended warranty program for problems stemming from the headlamp modules for 12 years or 150,000 miles, whichever happens first. Unfortunately, the headlamp problem just began for me in 2019 at which point the car was 13 yrs old and was not covered by the extended warranty program or the safety recall, which is simply absurd ! At the very least gm should now include the 2006 pontiac grand prix model in the 14291 product safety recall. But gm really needs to release a permanent fix for the problem rather than a temporary fuse replacement every couple months. Has anyone investigated if these overheated headlamp driver module relays have caused electrical fires or melted the under hood bussed fusebox? If gm is not willing to step up and take responsibility, I hope we consumers can count on the federal safety agency office of defects investigation (odi) to force gm to do the right thing. Thank you in advance for looking into this serious matter.

Car has been continually overheating, radiator has been flushed and refilled with fresh coolant and new thermostat was bled. Car is fine while driving over 50mph but overheats when in traffic at a light. Driver back window motor is out, the window goes down but won't go up. The car stopped abruptly while driving and had to pull on the side don't know what happened but it won't start up but the lights come on inside the vehicle. I have had trouble since purchasing this vehicle. Gm needs to take this vehicles completely off the road they have stop making them and I can see why they're nothing but money eaters.
