1
Inspect the powertrain
What to look for: Hesitation on takeoff, harsh or delayed shifts, vibration at highway speed, fluid leaks on the driveway under the engine bay or transmission pan. (8 owner complaints on this vehicle
· typical repair $2,500 · failures cluster ~10,788 mi)
On the test drive: Drive 15+ minutes including a freeway on-ramp at full throttle, a steep hill, and stop-and-go traffic. Listen for clunks on shifts, flares between gears, and shudders during light acceleration at 30–50 mph (torque converter symptom).
What to look for: Wiper streaks even on a fresh blade, blower fan that doesn't change speeds, foggy or yellowed headlight lenses, sunroof drains plugged (water on headliner). (6 owner complaints on this vehicle
· typical repair $350 · failures cluster ~25,750 mi)
What to look for: Dim or flickering dash lights at idle, slow window operation, intermittent infotainment glitches, parasitic battery drain (dead battery after a few days parked). (5 owner complaints on this vehicle
· typical repair $850 · failures cluster ~61,478 mi)
On the test drive: Cycle through every electronic accessory during the drive — heated seats, defrosters, climate fan on max, cruise control. Glitches show up under load.
What to look for: Paint mismatch between panels (prior accident), rust on rocker panels and wheel wells, door alignment gaps that don't match side-to-side, weatherstrip wear. (4 owner complaints on this vehicle
· typical repair $1,500 )
What to look for: Blue smoke on cold start (oil burning), white smoke at temperature (coolant), knock or tick that doesn't go away after warm-up, oil spots under the vehicle. (3 owner complaints on this vehicle
· typical repair $3,100 · failures cluster ~110,000 mi)
On the test drive: Drive until the gauge reaches operating temp, then check temp stability under load on a hill. Surging or temp climbing under load = thermostat or water pump.
