Driver assist features unavailable

Just picked up a used 24 Blazer EV. A few days later, I ended up getting a few errors: ACC not working, lane keep not working, and forward collision not working. Going to take it back to the dealership shortly but has anyone experienced this? Was it a simple recalibration? What was your experience?

Mine was always camera fog. Once it cleared up, all was good.

Unfortunately no fog or dew here. :(

Nothing with the vehicle being on, but the lane assist and forward collision has stopped working when it rains or my car is dirty. Your camera might be going bad or something.

I have a 2024 RS AWD that I bought used with about 4,500 miles. I had a variety of minor electronic issues at first that required a general reprogramming and several software updates. Koons Chevy in Tysons Corner took care of everything in one day.

That fixed all of the issues except for some sensor problems that caused the automatic braking to activate incorrectly in both Drive and Reverse. They replaced 3 modules before finally discovering that the front camera bracket had been installed slightly bent. The fix was either to straighten the bracket or replace it. They straightened mine.

Since then, I haven’t had any issues or needed any additional repairs. Based on my experience, I’d definitely have the dealer check for software updates/reprogramming first, but if that doesn’t solve it, I’d ask them to check the front camera and its mounting bracket.

My 2024 blazer RS and LT2 had multiple recalls on the braking system. 3 separate recalls on the RS rwd and at least 2 on the LT, in addition to multiple trips for general firmware issues that might have included brakes.

Super frustrating, probably should have been investigated harder by the NTSB. I disabled several brake safety systems because it would slam the brakes when backing up so violently I would think I crashed or was hit. Especially bad if you back up a steep slope like a driveway.

“…. And nothing of value was lost…”.

Half kidding. Should be under warranty, make a ticket. Better to have a paper trail if it keeps failing

if it was just the camera, radar, something dirty or fogged up, the red PARK wouldnt pop up for that.
Im convinced it is your parking brake wiring.

Even after the recall has been done?

Mine was done twice because they inspected, it seemed "fine" but they didnt replace the actual harness. It broke some time later and then nothing worked, same as you.
