Warning lights issue on used Camry

[CoffeeAndTV]

My stubborn wife bought a car on her own, without consulting me. I told her to wait 'till I got back from work trip but she didn't listen.

She bought a 2022 Camry XSE from the dealer.

It hasn't even been a week, and now a whole bunch of warning lights are on, like the check engine light, and lights for the precollision system, LTA, cruise control, parking brake, and the secondary collision brake.

I tried to check the battery, and it seemed okay.

I even brought the car to O'Reilly's to check the engine light.

the third cylinder light came on, they thought it was bcs the injector.

But I don't think an injector would make all those other safety features stop working.

My wife was interested probably bcs this car has low miles (36,000) and it's the car she have always wanted

What should we do now guys, any suggestions?

The injector issue may be triggering the check engine light which can cause other system warnings. Have you checked if the batt voltage is stable or if there's a lose connection?

you know, the most likely culprit for a misfire on a low mileage car like that is a bad ignition coil or a faulty spark plug. A lot of times, a failing coil will cause a misfire, and it's a super easy and cheap thing to replace.
I think you should start there before jumping to a bigger, more expensive repair like an injector
