Airbag on other Corolla years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020, 2022, 2026.
What this problem usually is
Airbag complaints split into a few kinds. The most common is an airbag warning light that won't go out. Others involve the passenger seat sensor switching the passenger bag off with an adult sitting there, an airbag that didn't deploy in a crash, or one that went off without a crash at all. A large share also come from owners waiting on a recall part.
What got replaced
Owners who name the part that was replaced mention the occupant sensor (10 reports).
Recalls and investigations
One recall on the airbags covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
During certain crashes, the air bag electronic control unit (ECU) may malfunction, possibly disabling the deployment of the air bags and/or seat belt pretensioners.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2018 Toyota Corolla that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Some 2005 ? 2022 model year Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty smell is present. Follow the procedures in this bulletin to remediate the odor and address this condition.
What owners wrote
“I was driving home from church late Sunday night. A really rough storm hit and it knocked down a huge tree in the road covering the entire road. I did not see the tree until I got up on it and I went straight through it. I was running around 40 mph and total front end impact took the whole bumper off but my airbags did not deploy.”

“A car was going to hit my car, I went to hit the horn and the horn doesn't work a few days later a airbag light went on. Went to the dealership and they said it's a know malfunction in toyota corolla. They are not sure if the airbags will work or not. They recommend that I put a notice in for recall since there are still no recalls. This is a huge safety issue.”

Should you keep driving it?
This page can't tell you that. 17 of 36 reports involved a crash and 12 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
