For 23,293 Cadillac Lyriqs built in the 2023 and 2024 model years, the recall paperwork exists but the cure may not. The brake software meant to correct a low-speed loss of braking is, by GM’s account as reported by Auto123, not yet ready for those two model years. The owners of the oldest Lyriqs are therefore listed in a recall without a finished remedy.

Auto123 reported on Nov. 7 that the update code for those cars is still under development, and gave no date for completion.
The 474 and 22,819 Lyriqs at the back of the line
GM’s Part 573 report, filed under NHTSA campaign 26V717, counts 474 Lyriqs from model year 2023, built between Dec. 14, 2022, and April 28, 2023, and 22,819 from 2024, built between Jan. 20, 2023, and Sept. 20, 2024. Both groups are limited to the performance all-wheel-drive version. They are the oldest cars in a 67,380-vehicle action that also reaches newer Lyriqs, Blazer EVs, Vistiqs and Celestiqs.
GM’s recall filings, and the gaps in them
The statement that the fix is unfinished comes from Auto123’s account of the recall, which quotes GM’s position as still under development. The Truth About Cars agrees, writing that the update has not been released for these model years and those owners must wait.
The federal paperwork is quieter. The filing gives no separate availability date for 2023 and 2024 vehicles and says the same brake control module update will arrive by over-the-air download or at a dealer. NHTSA’s Nov. 3 letter to GM lists 2023-2027 Lyriqs without singling out the oldest ones. Newer builds are ahead: the filing dates the 2026 Lyriq production fix to Sept. 7, 2026.
The count has also grown. Recall 24V589 reached Lyriqs built through Aug. 5, 2024, while the new filing runs the 2024 model year to Sept. 20, 2024, and its totals for 2023 and 2024 combined exceed the 2024 campaign’s 21,469 by 1,824. GM’s 2024 filing assumed about 1 percent of those vehicles had the defect. The 2026 filing treats the entire population as affected, which changes what an owner of a 2023 or 2024 car should assume about a car that has already been updated once.
An update from 2024 that did not close the case
These owners have been through a version of this once. In August 2024 GM filed recall 24V589 for 21,469 all-wheel-drive Lyriqs from 2023 and 2024, citing software that could make the anti-lock system keep releasing brake pressure, and promised an update that corrected the false detection of wheel slip. GM’s 2026 report says pAWD vehicles under that campaign are rolled into the new one and closed under the old number, because the fresh software addresses both conditions.
What reopened the matter was a garage. A 2024 Lyriq that already had the earlier software hit a wall at low speed in April 2026, and a GM technical expert submitted a Speak Up for Safety report on April 10. GM counted 24 related complaints, 20 minor collisions and two alleged minor injuries from February 2024 to June 2026.
GM’s report does give factory-correction dates for newer cars: Aug. 8, 2026, for the 2027 Blazer EV, Sept. 7 for the 2026 Lyriq and Oct. 21 for the 2027 Vistiq, with no date listed for the 2027 Celestiq. Nothing comparable appears for the 2023 and 2024 Lyriqs, whose production windows closed on April 28, 2023, and Sept. 20, 2024. Those two model years also make up more than half of the 44,585 Lyriqs in the action, since the 2025 model year adds 11,926, the 2026 year 9,322 and the 2027 year 44. The unfinished piece is therefore not a corner case. It is the largest single block of the recall’s biggest nameplate.
The Dec. 14 mailing and the numbers to call
When the software does arrive, the delivery route depends on the owner. The filing says over-the-air installation is open to those who have accepted the applicable terms, and everyone else would book a dealer visit. For a 2023 or 2024 Lyriq that already took the 2024 update, the new code is meant to replace it and cover both conditions at once, so a second trip to a service department is the likelier outcome for owners who never enabled wireless updates.
The Nov. 3 letter from the safety agency says it had received GM’s proposed owner notice and that the draft was under review, with mailing expected Dec. 14, 2026. GM’s filing calls it a phased recall with no interim notice, so owners of the oldest Lyriqs should not expect a separate letter before then. Cadillac customer service is at 1-800-333-4223 and the NHTSA Vehicle Safety Hotline at 1-888-327-4236. A VIN search on NHTSA’s recall page shows unrepaired recalls, though the agency cautions that newly announced campaigns may not list every VIN.
The unanswered question is when the 23,293 oldest Lyriqs get a release date. GM’s filing names no person who owns that schedule, and the only stated date in the records is the Dec. 14 mailing.
