2019 Toyota Sienna Problems

Half of the owners who gave a mileage had the problem by about 12,000 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.

My fuel pump has been replaced by the dealer with the recalled part. The vehicle still does the same thing it has been doing since purchasing. It acts like it is not getting gas so hesitates multiple times constantly while driving. Sometimes I pull out and there is a delay in the engine getting gas then it kicks in and is a jerky ride.…Owner complaint, filed 2020, at 30,000 miles

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

• 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.

About 2 years after the 9/30/2019 purchase (new), the paint on the front engine hood began peeling & cracking. Calls to Parks Toyota were ineffective. Now the entire hood has pervasive cracks. The hood needs to be removed, sanded & painted with a more substantial, long-lasting paint. The paint used is supposed to contain an additional…Owner complaint, filed 2026

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.

• Test every switch: windows, locks, mirrors, seat heaters, the screen, the backup camera, Bluetooth and every USB port.

• Have the battery and charging system tested. A weak alternator or battery drain shows up here.

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.

• The tire pressure light should go out after startup.

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.
