The 2005 Uplander suspension complaints center on five distinct problem areas. First, excessive motor mount wear and undercarriage damage cause vibration during acceleration and turns, along with rapid tire wear from misalignment—one owner burned through six tire sets before bald tires returned. Second, front hub bearings fail prematurely, lighting the ABS warning; replacement doesn't cure it, and dealers then blame computer wiring, leaving owners facing unwarranted repair bills for a dealer-acknowledged recurring defect. Third, trailing arm and bushing failures produce loud rattling at highway speeds; in one case, the arm broke completely at 25 mph, severing the brake line and nearly detaching the rear axle. Fourth, the rear axle attachment welds fracture at highway speed, causing the rear end to track sideways—a structural catastrophe with six kids aboard in one report. Fifth, undercarriage rust within nine months causes the rear passenger wheel to separate from the body, producing clunking and squeaking but no safe repair option. The vehicle also exhibits persistent front suspension pulling even after alignment and tire replacement.
Failure modes owners describe
Excessive engine movement and undercarriage damage
Rear motor mount loses ability to hold engine solid; engine moves excessively on cradle. Rub marks develop on left drive axle. Independent mechanic suspected caster/camber misalignment leading to outer tire wear on both sides. Manufacturer eventually deemed vehicle unrepairable due to undercarriage damage.
When: Early in vehicle ownership
Symptoms owners cite: Noise and excessive vibration when accelerating or turning steering wheel; Rub marks on left drive axle; Outer tire wear on both passenger and driver side; Excessive engine movement on cradle
Repairs/costs cited: Dealer replaced tires, struts, hubs, and undercarriage parts without diagnosing root cause. Independent shop only inspected, did not repair. Eventually manufacturer offered replacement vehicle.
Recalls/TSBs owners mention: Manufacturer offered replacement vehicle; determined vehicle could not be repaired due to undercarriage damage but never specified reasoning
Premature tire wear and suspension stability issues
Vehicle exhibits rapid tire wear and instability on highways. Owner reports placing six new tires on vehicle because they were bald at 13,000 miles on first set. Front tires bald again shortly after. Vehicle unstable to drive on highway; caster/camber suspected out of alignment.
When: Early mileage; first set bald at 13,000 miles
Symptoms owners cite: Tires bald at 13,000 miles; Rapid repeat tire wear on front; Vehicle unstable on highway; Excessive vibration
Repairs/costs cited: Multiple tire replacements; suspension misalignment suspected but not confirmed by dealer
Front wheel hub bearing failure triggering ABS light
ABS light illuminates and cycles on and off regularly. Dealer diagnoses front wheel hub bearing wear. Both front hub bearings replaced at owner expense; ABS light returns. Dealer subsequently identifies computer and wiring system fault as cause. Dealer advises operation is dangerous until repaired. Dealer notes this is a recurring problem on model but insufficient complaints for recall.
When: During normal driving
Symptoms owners cite: ABS warning light on and off cycling; Humming noise from left front hub area
Codes mentioned: ABS light
Repairs/costs cited: Front wheel hub bearings replaced at owner expense; computer and wiring system identified as needing replacement, also not covered under warranty initially
Recalls/TSBs owners mention: Dealer acknowledged recurring problem on this model but stated insufficient consumer reports for recall; repairs required at owner expense; dealer instructed operation is dangerous until repaired
Trailing arm and trailing arm bushing failure
Abnormal rattling and clunking noise from rear suspension at highway speeds. Diagnosed as trailing arm or trailing arm bushing failure requiring replacement. Manufacturer defect confirmed by dealer. One complaint reports trailing arm broke off completely at low speed, causing rear axle to begin separating and breaking brake line.
When: 100,000 miles reported in one case; 25 mph in catastrophic failure case
Symptoms owners cite: Loud rattling or clunking noise from rear suspension at 45 mph and higher; Squeaking noise suggesting loose connection; Sharp tug and sway while driving at highway speed; Trailing arm completely breaks off
Repairs/costs cited: Dealer lubricated front suspension and stated nothing else could be done per manufacturer investigation. One case ended in complete trailing arm separation and rear axle failure.
Recalls/TSBs owners mention: Dealer stated manufacturer defect on front suspension; per manufacturer investigation, lubrication only solution offered. NHTSA campaign 10V110000 (Suspension) referenced but owner VIN not included
Suspension pulling and alignment issues
Front suspension pulls to left and right without warning while driving at various speeds. Dealer performs front alignment; problem persists. All four tires found worn and replaced. Problems continue after repairs. Owner also reports instrument cluster and headlight flicker at idle, sensor replaced, issue persists.
When: During normal driving at various speeds
Symptoms owners cite: Pulling to left and right side without warning; Worn front and rear tires; Dashboard and headlight flicker at idle
Repairs/costs cited: Front alignment performed; four tires replaced (Continental P225/60R17); exterior light sensor replaced
Recalls/TSBs owners mention: Manufacturer alerted after repeated failures following repairs
Undercarriage rust causing rear axle separation
Severe undercarriage rust develops on rear passenger side within nine months of purchase, causing separation of rear passenger wheel from vehicle body. Clunking and squeaking noise during driving suggests wheel connection failure. Affected area cannot be replaced or welded safely per owner.
When: Within 9 months of purchase
Symptoms owners cite: Severe rust on rear passenger undercarriage; Separation of rear passenger wheel from body; Clunking and squeaking noise during driving; Wheel at risk of detaching
Repairs/costs cited: Owner reports affected area cannot be replaced or welded safely
Rear axle attachment weld failure
Welds attaching rear axle to body fracture while driving at highway speed (75 mph). Rear end begins tracking sideways; vehicle becomes unstable. Structural failure of critical suspension attachment point.
When: During highway driving at 75 mph
Symptoms owners cite: Sharp tug followed by sway at highway speed; Rear end tracking sideways; Vehicle instability
Repairs/costs cited: Broken welds on body-to-rear-axle attachment point
