2021 Toyota Corolla Problems

Half of the owners who gave a mileage had the problem by about 55,000 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.

On May 22, 2026, I got off work and started my 2021 Toyota Corolla LE when I noticed the SRS airbag warning light was on. The warning light has remained on ever since. I am concerned that my airbags may not function properly in the event of an accident. I recently contacted Toyota corporate because I learned about a possible airbag…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.

During the lower interval settings, wipers will not work in proper order. Sometimes you may get three quick wipes and them the wipers will stop in middle of windshield for about 5-8 seconds. Sometimes the wipers are inconsistent with proper timing and will not properly work all the time.Owner complaint, filed 2026

When the windshield wipers are set to intermittent they would swipe as if they were set to lo and then they would come to a complete stop at a 45° angle sometimes starting up again but other times I would need to turn the windshield wipers off then back on for them to go again.Owner complaint, filed 2025

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

Half of the owners who gave a mileage had the problem by about 11,000 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.

• 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.

Glare in the cluster panel during the day. This causes me to not be able to see what is being shown on the cluster panel such as speed, engine temperature, or any other warning lights.

What to check before you buy

• Turn the wheel lock to lock while parked and listen for groaning, clicking or binding.
• On a straight road the car should track straight with the wheel centered and no loose feeling.
• A power steering warning on the dash, even briefly, deserves a mechanic’s look before you buy.

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.

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