There are numerous service bulletins on quantum's website, www.qtww.com , under products and service bulletins that say many different parts of their fuel systems will fail.it also states that their bracket system holding the tanks in place will allow the high pressure tanks to move laterally that could cause a rupture in the fuel lines or the tank itself. I have contacted them to have the parts replaced and they are refusing to change them or tell me how i can make my systems safe for my employees to operate.i have a huge concern for the safety of my employees while operating these systems until the parts that will possibly fail have been replaced.in addition they are not following the nfpa 52 guidelines for the location of the prd vents which in the event of a fire and the current location of the vents would discharge fuel directly into the flames.they currently are still not following the guidelines as of today.as i'm sure you can understand my concerns and would like to have these issues resolved for myself and anyone else that has purchased these fuel systems from this manufacturer.i have attached a few of the bulletins from their website that are issues with my systems to show that they are aware of the issues and if you like i can send you the email conversations between myself and quantum to show that they are not doing anything to rectify or fix the issues.thank you in advance for anything you can do to assist us in resolving these issues and make our systems safe for our employees to operate.
Seat belt cable becomes frayed and breaks. Will break completely if in an accident. With nothing holding driver in driver will become injured and possibly death. Replace with a better constructed device

The contact owns a 2016 kenworth t680. While driving 65 mph, the steel drum from the tire fractured in pieces when the brake pedal was depressed. The vehicle was taken to an independent mechanic who diagnosed that the steel plate drum was not welded correctly. The steel plate drum was replaced. The manufacturer was not notified of the failure. The failure mileage was 20,000.

The defrost doors in the t680 is weak and breaks often leaving the driver without any defrost causing his visibility to decrease in an unsafe manner.kenworth has been unwilling to address this issue and repair it. When i contacted our district service manager he knew the part number of the replacement door assembly from memory and stated in an email back to me that kenworth has identified the issue and is working to fix it on future models. Labor to repair this is over $3000 and the part is another $886. We have 12 of these vehicles, so far 5 of the 12 have broken leaving more than one driver struggling to get off the highway before his window fogged up so bad he became unsafe to drive. The vehicles are in motion when these defrost doors break and it creates a very unsafe situation as trucks can not just pull over any spot they choose on the highways and wait for a window to thaw out. There are 2 issues that happen on these doors. 1 the door is overflexed by the electric actuator motor and snaps the drive cogs off of the door. 2 the doors either shrink or are too small to begin with and the drive cog does not make full contact with the actuator motor causing the teeth to strip out as in the photos attached. The drive cog should be extruded from the housing but as you can see are shrunk inside the housing.
