GM has opened a free program for a handful of 2026 Cadillac CT5-V Blackwings that came with the Precision Package but left the factory without the package’s billet aluminum rear toe links. The cars run fine. Eleven buyers paid for track hardware and opened a trunk with nothing in it.
What went missing
Cadillac’s own option description lists “unique billet aluminum rear toe links” as part of the Precision Package, there to “enable a more aggressive track alignment.” The rest of the package includes:
- Redesigned front knuckles for more camber
- Stiffer bushings throughout
- Revised spring rates
- Carbon-ceramic brakes
- Michelin Pilot Sport Cup 2 R tires
- Retuned steering, MagneRide and eLSD calibrations
GM never bolted the links on at the factory. They ride in the trunk. Precision Package owners have posted about finding two sealed boxes of silver links back there at delivery. The car leaves Lansing on its standard links with a street-friendly alignment. The track pieces go on later, if and when the owner wants them.
GM’s Customer Satisfaction Program N262573420 covers 11 U.S. cars whose trunks were empty. The remedy is about as simple as warranty paperwork gets: GM mails the owner, the dealer orders the links, and the parts go where they should have been in the first place. The program is free and runs through October 2028.
Why a toe link matters
The Blackwing uses a multi-link rear suspension. The toe link is the arm that sets whether each rear wheel points slightly inward or outward. Rear toe decides whether the back of a 668-horsepower sedan stays behind you at the limit or comes around to say hello. A little toe-in makes the rear end planted and predictable. Too much costs you tire wear and drag.

Cadillac designed the Precision Package’s front knuckles for aggressive wheel alignment on track. Once you add front camber, the rear geometry has to follow, or you’ve built a car that turns in brilliantly and then wants to swap ends. The billet links are how GM gives owners that rear adjustment range without making daily drivers live with a track alignment.
Recall, it isn’t
Don’t expect a NHTSA recall number. A recall under federal law covers a safety defect or a noncompliance with a safety standard. These cars are running the same factory steel links as every non-Precision Blackwing, so nothing is unsafe. They’re just incomplete.
That doesn’t mean it stays private. Federal rules require automakers to send NHTSA copies of any communication tied to a customer satisfaction campaign that goes to more than one dealer or owner. That’s why quiet fixes like this one end up in the public record.
What owners should do
Check the trunk before the mail arrives. If your Precision Package car came home without two boxed links, call your Cadillac dealer and ask them to run your VIN against N262573420.
Plan the install separately. Under GM’s remedy, the dealer supplies the parts. Fitting them is your call, and it’s not a bolt-on-and-go job. Changing toe links means a four-wheel alignment afterward. Use a shop that understands track specs, not one that resets everything to the factory street numbers out of habit.

Keep the boxes if you’re not tracking the car. For a collector or a street-only owner, those unopened links are part of the car’s completeness. Any future buyer of a Precision Package Blackwing will check for them.
Mind the deadline. Two years sounds generous until the car changes hands. If you’re buying a used 2026 Precision car, make sure the links are in the car before closing. After October 2028, you’ll be paying for them yourself.
The bigger picture
The supercharged 6.2-liter Blackwing, rated at 668 horsepower, comes with a Precision Package that Cadillac calls an option of extremely limited availability.
Eleven cars isn’t a big miss. But Precision Package buyers tend to be the kind who open the trunk the day it arrives, so GM is smart to fix this fast. Pop yours. If you bought the Precision Package, what did you find back there: two boxes, or bare carpet?
