2023 Cadillac Lyriq Recalled Over Service Brakes
A loss of braking ability increases the risk of a crash.
Here’s the short version: GM found a software bug in the brake control module on a batch of its electric Cadillacs and one Chevy, and in the wrong conditions that bug can cost you braking. That’s about as serious as a recall gets. If you drive one of these vehicles, this is the one you don’t put off.
What’s actually failing
The part at the center of this is the brake system control module, or BSCM. Think of it as the computer that manages the hydraulic and anti-lock side of your brakes. On these EVs, a lot of braking is handled electronically, and the BSCM is running the show.
The filing says the module has a software defect that may cause a loss of braking during certain driving conditions. No new part, no cracked line, no worn pad. It’s code. But the result is the same thing you fear most behind the wheel: you go to stop and the brakes don’t respond the way they should.
GM doesn’t spell out exactly which “certain driving conditions” trigger it, so I’m not going to guess. What matters is the consequence, and NHTSA states it plainly: a loss of braking ability increases the risk of a crash. There’s no softer way to read that.
What the filing says
This is NHTSA recall campaign 26V717000, received October 29, 2026. GM’s internal number for it is N262570900.
The recall covers 67,380 vehicles. The full population named in the defect filing is broad: certain 2023–2027 Cadillac LYRIQ, 2025–2026 Cadillac CELESTIQ, 2024–2027 Chevrolet Blazer EV, and 2026–2027 Cadillac VISTIQ. The fix is a BSCM software update, pushed either over the air or done at a dealer, free of charge.
VINs tied to this recall became searchable on NHTSA.gov on October 29, 2026. Owner notification letters are expected to go out December 14, 2026. That’s a gap of several weeks between the VIN lookup going live and the letters landing in mailboxes, which is exactly why you shouldn’t wait for the mail.
What this means if you own one
-
Run your VIN now. Go to the NHTSA recall page for campaign 26V717000 and enter your 17-digit VIN. Since the VINs went searchable October 29, 2026, you can confirm today whether your specific vehicle is included — you don’t have to wait for the December 14 letter.
-
Take any braking symptom seriously. This is a brake defect. If your pedal feels off, if stopping power seems inconsistent, or if a brake warning comes up, treat it as urgent and get the car looked at. Don’t talk yourself out of it. A software issue that affects braking is not something to drive around with and hope.
-
Know how your fix arrives. The remedy can come as an over-the-air update or a dealer service visit. If you get an OTA notification, follow the instructions and make sure the update actually completes. If GM tells you to go to the dealer, book it. Either way, the repair is free. You should never pay a dime for a recall remedy.
-
Document everything. Keep the recall notice, any service records, and dates. If you’ve already had brake trouble, write down when it happened and what the car did. If you need warranty or goodwill help later, a paper trail is your friend.
-
Call if you’re stuck. Cadillac customer service is 1-800-333-4223. Chevrolet owners can call 1-800-222-1020. GM’s reference number for this recall is N262570900 — have it handy.
If you want background on your specific model, these are the hubs worth checking: 2023 Cadillac Lyriq, 2024 Cadillac Lyriq, 2025 Cadillac Lyriq, 2026 Cadillac Lyriq, 2025 Cadillac Celestiq, 2026 Cadillac Celestiq, and 2026 Cadillac Vistiq.
The honest take
A software recall on an EV sounds minor until you remember what the software controls. Here, it’s the braking system. The good news is the fix is free and, for a lot of owners, it can land over the air without a trip to the dealer. That’s the upside of how these cars are built.
The thing I’d push back on is waiting. The VINs are already searchable, but the letters don’t go out until mid-December. That’s weeks of driving a vehicle with a known braking defect while you wait on the mail. Don’t do that. Check your VIN, confirm your repair path, and get the update installed as soon as it’s available to you. On a brake issue, there’s no reason to sit on it.
