2020 Toyota Tundra Problems

Half of the owners who gave a mileage had the problem by about 1,000 miles.

What to check before you buy

• Smell around the engine bay and under the rear of the car for raw fuel.
• On the test drive, accelerate firmly from a stop and up a grade. Stumbling, surging or a flashing check engine light are red flags.
• Fuel pump recalls are common. Check this exact VIN for open recalls before you buy.

Vehicle has had 3 other similar episodes all resulting in the vehicle losing power at high speed. Vehicle was towed to local Toyota service dept. where they said it generated a code for rough idling - low fuel.…Owner complaint, filed 2022

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.

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.

• Where it is safe, try the adaptive cruise and lane keeping on the test drive and watch for sudden braking or warnings with nothing there.
• Check the windshield in front of the camera and the bumper sensors for cracks, chips or poor repairs.
• Ask whether the windshield has been replaced. The camera has to be recalibrated afterward, and many shops skip it.

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.

• Open and close every door, the hood and the liftgate, and lock and unlock each one.

• 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.
