GMC Suburban stalling problems

On the gmc 6.5 the pmd, or pump mounted driver fails due to heat failure, also failing for no reason in 8 degree temperatures. When it fails there are no signs, warnings just stalling the power steering, power brakes gone. Now put yourself on a 2 mile hill of an insane descent, and yourself behind the steering wheel what would you do? This is insanity that the dealership will only help you if there is less than 100,000 miles on your car, and then all they do is replace the pump, when the pump isn't the problem its the pump mounted driver. I personally have spoken to and been to the manufacturers and they refuse to admit there is a problem, this is the manufacturer! But I don't understand how after 11 years nothing has been done about this problem, only a rip and replace, and if there's to many miles to bad for you. I have tried almost every after market solution out there and these manufacturers too are baffled about this situation. So why if there is no problem are there a dozen business making money off of trying to fix the manufacturers problem? If the manufacturer doesn't have to take the blame than who does? The family of 7 that wrote in? When they die is something going to be done , because its not a matter of if, its a matter of when, and I hope that day never happens. But I hope that more than the family has trouble sleeping because I feel better for trying to avoid this catastrophe. Thank you for you time. Sincerely concerned, jon lamb

Vehicle engine will intermittently stall or cut out at highway speeds. This condition occurs approximately once or twice a month under varied driving conditions. The vehicle will restart immediately after stalling. Several times when this has occurred, the service engine light will come on, but it will turn off after 20-30 miles of driving. This has been occurring for over a year now, I have taken the vehicle to three gm dealerships, and they claim they cannot replicate the problem. They have replaced the fuel pump at my expense, and the catalytic converter under warranty. I have also taken the vehicle to two independent shops for the same problem and they have also not been able to replicate the problem or offer a solution, other than replacing the basic components (spark plugs , plug wires, fule filter etc), which I have had done.. This is an extremely dangerous problem, primarily because when the engine stalls, the power brakes and steering also fail. I live in a mountainous region of virginia and have had this happen while driving mountain switchbacks. This vehicle weighs almost six thousand pounds, and a loss of power brakes and steering while descending steep mountain grades with sharp curves creates an extremely dangerous and life threatening situation. Thank you for your assistance.

We have a 1996 6.5 turbo diesel gmc suburban. We had severe stalling problems. The dealer replaced the fuel pump at their cost and installed at our cost, new glow plugs, glow plug sensor, battery, and battery cables suspected to be the problem. It continued to stall. We returned to the dealer and they replaced the pump again at their cost, but we had to pay to drop the tank to check for contamination. There was a deteriorated screen we paid to replace. It still stalled. Only this time it stalled when I was going 50 MPH and approaching curves along the river. I lost all power steering and brakes. Me and my five young kids almost ended up in the river. Had it been normal winter roads, we would have. All along we've done research and had it rediagnosed by a professional diesel mechanic, so we knew to tell our dealer (automall in brattleboro vermont) to replace the pump mounted driver (pmd) sometimes called a fuel solenoid driver (fsd). After problems where automall tried to rip us off for a fake $100 deductible, they will install it at no charge tomorrow (1/7/04). We have driven just over 1000 miles total. However, this does not fix the problem. From all the research we've done, weve discovered many people have reported the same dangerous accounts of stalling. Several report having almost had serious accidents like I had two days ago. According to research, pmd failures are the most common part to fail on gm 6.5 diesels. The pmd overheats because of placement near the engine. There is a simple, yet costly fix that consumers should not have to pay to be safe. A pump driver cooler (pdc) can mount on the firewall (not the engine) to move the pmd away from the heat. Please investigate and issue a recall to install pdc's on these engines so we can once again be safe in our vehicles. My family of 7 cant afford another stall, especially during these winter months, and new pdcs alone cant guarantee safety. Thank you.
