This vehicle is from the RX series, but it doesn’t have a V6 engine—it’s more like the NX models. That’s why I’m posting here, as maybe someone in this group has experienced the same issue.

I'm really frustrated now. I bought a 2020 model 2-liter RX300 with 60,000 km on it, and since I got it, the car has triggered warning lights three times. These warnings always appear in multiple ways, such as "Secondary Collision Brake System Malfunction," "Check Engine – Visit Your Dealer," and "AWD System Malfunction – 2WD Engaged."

I have taken my car to the service center three times, and each time, they provided a different reason—replacing the battery, changing the brake pads, etc.

This morning, I started the car, shifted into reverse, then into drive, and when I accelerated, the same warnings appeared again. By the way, these warnings always occur during take-off. If you know the reason, I would really appreciate your help.

 

Your car’s model / version isn’t offered here in the U.S./North America so forgive us if we’re a bit confused as I saw you had already asked the RX forum and glad someone directed you here.

I have a 2020 NX 300, 2.0 L 4-cylinder turbocharged engine and I have NOT experienced anything you’ve mentioned. However, your issues sound familiar like I’ve seen them discussed somewhere on this forum but not necessarily on the NX or RX models.

I’m at work but did a quick search and only found this

I know it’s not exactly what’s happening with you but could possibly help knowing there’s similar issues happening like yours.

I hope someone else can help shed some light into what you’re experiencing.
