BRAKING SYSTEM FAILURE AT LOW SPEEDS.
- Service brakes
WHEN AT SLOW SPEEDS, BRAKES GET HARD AND HAVE TO PUT A LOT OF PRESSURE TO STOP THE TRUCK.
- Service brakes
IF THE BRAKES ARE PUMPED 2-3 TIMES THE PEDDLE WILL BECOME REALLY FIRM AND HARD TO PRESS. WHEN THIS OCCURS THE TRUCK WILL NOT STOP. YOU HAVE TO STAND ON THE BRAKE PEDAL WITH BOTH FEET TO GET THE TRUCK TO STOP. PRETTY UNNERVING FOR A 75K MIKE TRUCK STILL UNDER DRIVETRAIN WARRANTY BUT NOT COVERED. I USE THIS TRUCK FOR WORK AND HAULING MY KIDS. I DON'T LIKE HAVING MY KIDS IN THIS VEHICLE!
- Service brakes
VACUUM PUMP FAILURE WAS NOTICED WHEN PARALLEL PARKING. AFTER HITTING BRAKE SEVERAL TIMES THEY STOPPED WORKING. TOOK EXCESSIVE AMOUNT OF FORCE TO STOP VEHICLE.

- Desiccated Air Bag Inflator RuptureOpen
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled…
