What's wrong?
The SL-4 brake light pressure switch on the 2020-2021 Crane LET2 is part of the brake light circuit. It reacts when air pressure is sent to the switch during braking. That pressure closes the internal electrical contacts, which tells the rear brake lights to turn on.
On affected switches, the threaded area was not made and tested with enough control. When air pressure reaches the switch, air can leak from the switch body. That leak can jam the internal electrical contacts, so the brake light signal no longer works as designed.
A leaking switch can make an audible air-leak sound that the driver can hear. If you hear that sound when applying the brakes, treat it as the warning sign described for this defect.
Who's affected?
For owners, the naming difference matters: 2020 vehicles are listed as Crane LET2, while 2021 vehicles are listed as Crane Carrier LET2, both with the same SL-4 pressure switch.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Jammed brake light switch contacts can leave the brake lights stuck on or stop them from lighting when you brake. Both conditions make it harder for other drivers to read your next move and increase crash risk. A leaking switch can make an audible sound, so treat that sound as a reason to schedule service soon. Repair is free at any franchised Crane dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Crane LET2 is included in this recall.
- Contact your nearest franchised Crane dealer to schedule the free brake-light-switch inspection and replacement that fixes the switch contact problem behind brake lights that stay on or fail to illuminate.
- Bring the recall notice if Crane has mailed one. If not, reference recall number 21V166 when you call.
- Use extra caution until the repair is complete. Check that the brake lights work before driving and leave extra following distance.
What happens at the repair
At the dealer, a Crane technician inspects the brake light switch manufacturing date on the 2020-2021 LET2. If the switch falls within the recalled production group, the technician replaces it. The inspection and any needed replacement are free under the recall. Crane has a general reimbursement plan on file for owners who already paid out of pocket for the same brake light switch repair before recall service. Bring repair documentation and ask Crane customer service or the service desk how to file under that plan.

Frequently asked questions
What is recall 21V166?
Recall 21V166 covers 298 2020-2021 Crane LET2 vehicles with certain SL-4 brake light pressure switches. The switch can leak when air pressure is supplied, jamming internal electrical contacts. Crane dealers will inspect the switch manufacturing date and replace the switch if needed for free.
What should I do if my 2020-2021 Crane LET2 is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 21V166. If it is, contact a franchised Crane dealer to schedule the brake light switch inspection. Reference recall 21V166 when you call, or contact Crane customer service at 1-877-546-2537.
Does the recall repair cost anything?
No. Crane's recall remedy says dealers will inspect the brake light switch manufacturing date and replace the switch if needed, free of charge. Use a franchised Crane dealer and reference recall 21V166 when you schedule service.
What is the safety risk?
The safety risk is brake lights that stay on or fail to illuminate. Either condition can increase crash risk because other drivers get the wrong signal about whether the vehicle is braking. Confirm your VIN, then ask a Crane dealer about safe use before inspection.
What warning signs should I watch for?
Watch for brake lights that remain illuminated after braking or fail to illuminate when the brake pedal is applied. Those signs match the brake light switch problem described in recall 21V166. Schedule the dealer inspection if your VIN is included.
