2000 ISUZU RODEO

Typical onset: 80,000-150,000 mi

Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke from exhaust on startup or acceleration, Knocking or rattling from engine block, Complete loss of compression, Seized engine

Fix: The 3.2L V6 suffers from inadequate piston ring design and oil control issues that lead to cylinder scoring, bearing failure, and complete engine destruction. Once symptoms appear, it's typically too late for anything short of a rebuild or replacement. Engine rebuild requires 18-25 hours; used engine swap runs 12-16 hours. Most owners find total loss and move on.

Estimated cost: $3,500-6,500

Typical onset: 90,000-140,000 mi

Symptoms: Harsh or delayed shifts, especially 2nd to 3rd, Slipping under acceleration, Transmission overheating, No movement in drive or reverse, Metal shavings in fluid

Fix: The 4L30-E transmission has weak clutch packs and inadequate cooling. The external oil cooler lines corrode and leak, starving the trans of fluid. Once slipping starts, internal damage progresses rapidly. Rebuild takes 10-14 hours; many shops won't touch them due to parts availability. Used trans swap is more common at 8-12 hours.

Estimated cost: $2,200-4,200

Typical onset: 60,000-120,000 mi

Symptoms: Transmission fluid puddles under vehicle, Burnt transmission fluid smell, Low fluid level on dipstick, Transmission overheating warning

Fix: The steel cooler lines rust through where they pass along the frame rails, especially in rust-belt states. Catching this early prevents transmission starvation and failure. Replacement involves both lines and fittings, about 2-3 hours labor. Always replace both lines even if only one is leaking.

Estimated cost: $350-650

Typical onset: 100,000-160,000 mi

Symptoms: Overheating with no obvious coolant leak, White smoke from exhaust, Coolant in oil (milky dipstick), External coolant seepage at head mating surface, Rough idle and misfires

Fix: The 3.2L V6 head gaskets fail due to thermal cycling and marginally adequate head bolt torque. Requires both heads pulled, decked, and pressure tested. Budget 14-18 hours labor. If overheating was severe, heads may be warped beyond machine shop limits. Often discovered during diagnosis of the engine oil consumption issue.

Estimated cost: $2,000-3,200

Symptoms: Clunking from rear suspension over bumps, Rear axle misalignment and tire wear, Visible rust perforation on frame cross-member, Sagging rear end, Failed state inspection in rust states

Fix: The rear suspension cross-member rusts from the inside out in salt states, eventually cracking or separating from the frame. This was serious enough for an NHTSA recall (01V268000) but many vehicles were never repaired. Requires frame section replacement or plating, 8-12 hours labor plus welding/fabrication. Some states will fail inspection and deem vehicle unsafe.

Estimated cost: $1,200-2,800

Typical onset: 80,000-130,000 mi

Symptoms: Hard starting after sitting, Sputtering or stalling under load, Loss of power on highway, Check engine light with lean codes, Won't start when fuel tank below 1/4

Fix: The in-tank fuel pump strainer clogs with sediment, and the inline fuel filter (often neglected) restricts flow. Pump replacement requires dropping the tank, 3-4 hours. Filter is 0.5 hours but often overlooked in maintenance. Replace both together if pump is being done. Many Rodeos never had the filter changed in their entire life.

Estimated cost: $450-800
