1 Verify safety recalls before you drive off

Recall fixes are free regardless of warranty status. Ask the seller for proof — or have the dealer pull the VIN history.

2 Inspect the airbags

What to look for: Anything that looks, sounds, or smells different from peer vehicles of the same year and trim. (127 owner complaints on this vehicle · typical repair $1,100 · failures cluster ~83,269 mi)

Walk around and note any visible damage, wear, or aftermarket modifications
Open the hood and look for fresh fluid leaks, loose connectors, or recent part swaps
Sit in every seat and operate every control to confirm function

3 Inspect the engine

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. (14 owner complaints on this vehicle · typical repair $3,100 · failures cluster ~55,533 mi)

Oil dipstick — level on the full mark, color amber not black, no milky residue (head gasket sign)
Coolant reservoir — level, no oil film floating, no rust
Spark plug wells (look down with a flashlight) — oil pooled means valve cover gasket
Timing chain or belt service history (interference engines = $1,500+ if it breaks)
Exhaust smoke briefly after a long idle then a rev

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.

4 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. (13 owner complaints on this vehicle · typical repair $2,500 · failures cluster ~67,733 mi)

Transmission fluid color and smell — fresh ATF is red, brown or burnt smell is bad
Engine and transmission mounts (cracks or visible sag)
CV boots front (and rear on AWD) — any tears mean a $300–$800 axle replacement
Driveshaft U-joints and rear differential fluid level on RWD/AWD

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).

5 Inspect the lighting

What to look for: Headlight lens haze that'll need restoration, dim low beams, condensation inside the housings, blinkers flashing fast (bulb out). (8 owner complaints on this vehicle · typical repair $250 · failures cluster ~75,529 mi)

Every exterior light — walk around with a helper pressing the brake, blinkers, hazards
Headlight aim — should not blind oncoming traffic; misaligned often after collision
Interior dome lights, glove box, vanity mirror lights, trunk light

6 Inspect the electrical

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). (6 owner complaints on this vehicle · typical repair $850 · failures cluster ~26,922 mi)

Battery age sticker — most batteries last 3–5 years
Alternator output at idle (13.8–14.5V is healthy)
All exterior lights: headlights both beams, taillights, brake lights, reverse, blinkers
Every interior switch: power windows, locks, mirrors, sunroof, seats
Infotainment cold-start time and touchscreen responsiveness

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.

7 Inspect the tires

What to look for: Uneven tread wear (alignment or suspension), feathering (toe out of spec), cupping (worn shocks), sidewall cracks (age). (6 owner complaints on this vehicle · typical repair $150 · failures cluster ~10,890 mi)

Tread depth at multiple points across each tire — should be even across the width
DOT date code on the sidewall — last 4 digits are week and year; 6+ years old = replace regardless of tread
Sidewall for cracks, bubbles, or repair patches
Spare tire — present, inflated, and the jack/wrench are in the kit

8 Paperwork — before you sign

The seller's transparency on these tells you what kind of seller you're dealing with.

Title in seller's name (not "open title" or "signed by previous owner")
Service records — at least the last 24 months
VIN on the dash matches the door jamb sticker and the title
Run a paid vehicle history report (Carfax or AutoCheck) — accident, salvage, odometer rollback
Confirm any open recalls have been completed (NHTSA VIN lookup)
If financing, get the rate in writing before you set foot on the lot
