2011 E-One Quest problems

What is wrong

E-one is recalling certain model year 2008 through 2011 cyclone ii, typhoon, and quest vehicles manufactured from may 1, 2008, through november 28, 2011, and equipped with meritor wabco electronic stability control (ESC) modules. Under certain road and driving conditions, vehicle body roll and road inclination characteristics may adversely affect the slip angle calculation of the electronic stability control (ESC) system. This might cause the ESC to perceive an over steering situation and therefore apply the outer wheel brake on the front axle until the vehicle is perceived to be stable.

Risk

If the driver is slow to react during this ESC intervention, the vehicle may deviate from the intended line of travel, increasing the risk of a crash.

Remedy

E-one will notify owners and is working with meritor wabco to replace the control module free of charge. The safety recall began on december 16, 2011. Owners may contact e-one customer service at 1‑800‑627‑5050 or meritor on track customer service at 1‑866‑668‑7221.

Recall number 11V564000 · Recall details

What is wrong

E-one is recalling certain model year 2010 and 2011 typhoon and cyclone ii and model year 2011 tradition and quest fire fighting chassis manufactured from november 24, 2010, through july 13, 2011, equipped with a cummins isb, isl, isc, or isx diesel engine. The v-band clamp assembly, part numbers q187684, q187685, and q187686, used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (doc)/diesel particulate filter (dpf) include a t-bolt which can fracture and fail when subjected to stress or load. A fracture or failure of the t-bolt may cause the clamp to loosen and the inlet or outlet sections attached to the doc/dpf housing to disconnect.

Risk

This could result in asphyxiation or carbon monoxide poisoning. The heat build up from the exhaust can also result in a fire. If both clamps fail, there is a risk in some applications that the doc/dpf housing may detach completely, creating a road hazard.

Remedy

E-one is working with cummins to identify and notify owners of the recall campaign. Repairs will be performed by authorized cummins dealers free of charge. The safety recall began on october 10, 2011. Owners may contact cummins at 1‑812‑377‑5000 or e-one at 1‑352‑861‑3223.
