2017 KEYSTONE KEYSTONE Suspension Problems

Subject: Catastrophic Suspension Failure Resulting in Total Loss of Trailer Braking Vehicle: 2017 Keystone Montana On January 5, 2026, while traveling at highway speeds, the rear driver and passenger-side leaf springs suffered a catastrophic "brittle fracture" failure. This resulted in the axle shifting 6+ inches, wedging into the chassis I-beam. The violence of the axle displacement severed the electrical brake wiring harnesses, causing a 100% loss of trailer braking. We were forced to perform an emergency stop of a 13,000lb+ load using only the tow vehicle’s brakes. Defect History & Pattern: This is the third suspension failure on this chassis. Previous repairs (documented) revealed factory-installed oversized hardware (screws) obstructing suspension travel. The failure mode matches the metallurgical defects described in NHTSA Recall 23V-822 (Hydrogen Embrittlement) and Safety Advisories 24-453 and 22-420. Safety Risk: The failure of the primary structural suspension led directly to the failure of the primary safety system...

The floor in the living room/kitchen area felt soft, so we removed the underbelly of the camper. It was noted that 2 cross members were broken away from the frame and 2 more have broken welds on the bottom of both sides. There is also a crack in the frame near where the door-side leaf springs attaches. This can only be viewed from the inside of the rail. This can be viewed upon request. This structural damage is making the camper unsafe to tow as the frame can flex too much and lead to camper disengagement. It is also causing the tires to rub on the inside shoulder increasing the risk of tire blow out. The camper is scheduled to be assessed by a local camper dealership. Pictures have been sent to the service department. A claim has been made to the insurance company but no adjuster has seen the...
