Polar Tank MC 331 Tank Trailer Recall 16V524: Trailer May Roll Away After Parking Due to Brake Delay

NHTSA campaign 16V524, reported July 11, 2016, 109 vehicles potentially affected.

What this recall means for you

Certain tank trailers may have Bendix SR5 spring brake valves that were improperly machined. This can delay the application of the spring brakes when the trailer is parked, so the trailer may not hold as it should.

If the spring brakes are delayed, the trailer may roll away after it has been decoupled from the tractor, raising the risk of a crash or injury. Owners should take this seriously, especially when parking on any slope.

Polar Tank Trailer will contact owners and provide a free remedy kit with instructions to repair affected SR5 trailer relay valves. You can also contact Polar Tank customer service at 1-320-746-2255. Check your vehicle identification number (VIN) for open recalls.
