Recall 18V235 covers 2018-2019 Isuzu Npr trucks with an unsecured brake switch. Isuzu will inspect and repair it free at a franchised dealer.
Isuzu is recalling 80 2018-2019 Npr Xd, Npr Hd, and Npr trucks because the brake switch and nylon retainer can be unsecured in the steel brake pedal assembly bracket. If the switch detaches, the brake lights stay on, the shift interlock stops working, and accelerator input is disabled, increasing crash risk; Isuzu dealers will complete the repair free of charge.

What's wrong?
On 2018-2019 Isuzu Npr, Npr Hd, and Npr Xd vehicles, the brake switch is mounted at the steel brake pedal assembly bracket. The switch reads pedal movement and tells the brake lights to come on when the driver presses the pedal. A nylon retainer clip holds that switch in the correct position.
On affected vehicles, the nylon retainer clip was not installed securely in the pedal bracket. If the clip is not seated, the brake switch can shift instead of staying fixed against the pedal assembly. That movement keeps the switch from doing its job consistently, so the brake lights do not respond the way other drivers expect when the truck is braking.
There is no warning sign before failure. The issue is in the switch mounting, so an owner is not given a clear pedal feel, sound, or dashboard warning that the retainer clip is loose.
Who's affected?
Spans 3 Isuzu models, Npr Xd, Npr Hd, and Npr, across the 2018 and 2019 model years, all tied to the brake light switch.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the brake switch and nylon retainer are not secured, the switch can detach from its bracket. That can leave the brake lights on when the pedal is not pressed, stop the shift interlock from working, and disable accelerator input, so the truck cannot accelerate and crash risk increases. Schedule the dealer inspection soon. Repair is free at any franchised Isuzu dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Isuzu Npr Xd, Npr Hd, or Npr is included in this recall.
- Contact your nearest franchised Isuzu dealer to schedule the free brake-switch retainer inspection and retainer-clip repair.
- Bring the recall notice if Isuzu mailed one. If not, reference recall number 18V235 when you call.
- Drive cautiously until the repair is complete. If the brake lights stay on, the shifter does not release, or the accelerator stops responding, stop driving and call the dealer.
What happens at the repair
At the dealer, an Isuzu technician inspects how the nylon retainer is seated in the steel brake pedal assembly bracket. If the retainer is not seated correctly, the technician re-seats the retainer clip or replaces it. The recall repair is free, including parts and labor. Isuzu has a general reimbursement plan on file for eligible out-of-pocket repairs paid before the recall notice. Keep repair orders and payment proof, then contact Isuzu customer service at 1-866-441-9638 or ask the service desk how to submit documentation.
