2017 Toyota 4Runner Problems

Half of the owners who gave a mileage had the problem by about 13,000 miles.

What to check before you buy

• The pedal should feel firm and the car should stop straight without pulling, grinding or a pulsing pedal.
• The ABS and stability control lights should go out after startup and stay out.
• Look through the wheels at the rotors. A deep lip on the edge means brakes are due soon, which is a fair thing to negotiate on.

Failed brake master cylinder, this is still a rather new vehicle and the mechanics said this is unlikely in a new low mileage vehicle. I did research and this has only happened a few times, seems like a safety recall should be put in place.Owner complaint, filed 2022

While driving at full speed on the freeway, another vehicle stopped suddenly in front of me. My brake pedal was soft and went down almost to the floor. Rapid pulsing of brakes, as would be expected with the ABS (antilock brake system), did not occur. I pulled around to the shoulder and barely managed to stop in time to avoid a collision…Owner complaint, filed 2021, at 55,000 miles

What to check before you buy

• Test every switch: windows, locks, mirrors, seat heaters, the screen, the backup camera, Bluetooth and every USB port.
• Watch the dash at startup. Every warning light should come on briefly and then go out.
• Have the battery and charging system tested. A weak alternator or battery drain shows up here.

For the 2nd time in 5 weeks, the main wiring harness and knock sensor have been eaten and destroyed by rodents. This has caused thousands of dollars worth of damage, and it's due to the soy based wiring used in the wiring harness. I cannot keep this vehicle outside for any period of time without the threat of the harnesses getting chewed.Owner complaint, filed 2026

My car was parked overnight and the next day when I got in to run errands and my check engine light was flashing and my trac off light was on. When I put the vehicle in drive it was very sluggish, I called the dealer and they sent a tow truck. The truck stayed overnight so they could diagnose but she was pretty sure that it was rodents…Owner complaint, filed 2017, at 1,599 miles

What to check before you buy

• The air bag (SRS) light should come on at startup and go out within a few seconds. If it stays on, the system may not work in a crash.
• Air bag recalls are some of the most serious. Check this exact VIN for open recalls and get proof any recall work was done.

The contact lost control of the vehicle and crashed into the median. The…Owner complaint, filed 2017, at 7,800 miles

What to check before you buy

• Look underneath with a flashlight. Utah road salt is hard on frames, brake lines and the bottoms of doors.
• Open and close every door, the hood and the liftgate, and lock and unlock each one.
• Use a paint thickness gauge and compare panels. A panel that reads very differently from the rest has likely been repaired.

What to check before you buy

• Ask the seller not to warm the car up, and start it cold. Listen for ticking, knocking or a rough idle in the first minute.
• Pull the oil dipstick and the oil cap. Low oil, a gasoline smell or a milky film on the cap are reasons to walk away or get an inspection.
• Plug in an OBD2 scanner. Stored or pending codes matter, and so do readiness monitors that show "not ready", which usually means the codes were cleared right before the sale.
• Ask for oil change records. A gap in the records on a model known for engine complaints is a negotiating point at minimum.

• Smell around the engine bay and under the rear of the car for raw fuel.

What to check before you buy

• Drive it from cold if you can. Shifts should be smooth in every gear, including reverse.
• Feel for slipping (revs rise without the car speeding up), shudder at low speed and a delay when you put it in gear.
• Listen for whining, which is a common CVT complaint, and clunks when you go from drive to reverse.
• If it has 4WD or AWD, engage it on the test drive and ask when the transmission and differential fluids were last changed.

What to check before you buy

• Read the four-digit DOT date on each tire. Tires older than about six years should be replaced, whatever the tread looks like.
• Check tread depth on all four. On AWD vehicles all four tires should match.
• The tire pressure light should go out after startup.
