I have had the lower steering arm replaced three times due to a bad bushing. once under warranty & twice I had to pay for it which is over $300.00 each time. this is not an uncommon problem with the chevrolet & gmc trucks. this is only noticeable while in motion.

    Mobilityworks is recalling 133 my 2005-2006 ford e250, my 2000, 2004-2006 e350, my 2000, 2005 e450, my 2005-2006 gmc 2500, gmc 3500, and my 2006 dodge 2500 vans equipped with ricon platform style wheelchair lifts. These lifts fail to comply with the requirements of federal motor vehicle safety standard no. 403, "platform lift systems for motor vehicles." the anti-stow interlock may not detect the presence of a wheelchair or mobility aid user. The pressure sensing switch that detects the presence of weight on the platform was not adjusted to the necessary sensitivity level. The lift could stow even though someone or something is still on the lift.

    Fix. Mobilityworks is working with ricon to correct the wheelchair lifts free of charge (please see 07e097). Owners may contact ricon at 1-818-267-3000 or mobilityworks at 1-800-769-8267.

The whole-line score for 2005, mostly half-tons: 2005 GMC Sierra.

No Lemon Index score: automakers report heavy-duty pickup sales together with the half-ton (one F-Series, Ram or Silverado number), so there is no honest per-truck denominator. These are counts and shares of owner complaints, not failure rates. Complaints: NHTSA owner complaints filed under the truck's 2500/3500 (F-250/F-350) names, all years filed, one per complaint number. Engine: decoded from the complaint's VIN (position 8 is the engine code) with NHTSA's vPIC decoder. Complaints filed as just “Silverado” or “Sierra” are left out (they mix 1500s and HDs). Older trucks have had more years to collect complaints, and popular years draw more because more were sold.
