Mack Trucks: Brakes Don't Fully Comply, But It's 'Inconsequential,' Promise!
Published Date: 3/24/2025
Notice
Summary
Mack Trucks found that some of their 2017-2026 Pinnacle and 2017-2019 CHU trucks don’t fully meet air brake safety rules. They asked the government to decide if this issue is minor and won’t affect safety. If you want to share your thoughts, you have until April 23, 2025, to speak up—no money changes or recalls yet!
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Owners May Not Receive Recall Repairs
If you own or operate one of these trucks, about 12,827 model year 2017–2026 Mack Pinnacle (PI/PN) and model year 2017–2019 Mack CHU trucks built between April 12, 2016 and December 19, 2024 have air reservoir volume that Mack says falls up to 1.5% short of the FMVSS No. 121 requirement. Mack petitioned NHTSA on January 15, 2025 asking to be excused from the duty to notify owners and to provide a remedy; if NHTSA grants that petition, owners of the affected vehicles that Mack no longer controls could not receive the notification or remedy that would otherwise be required.
Dealers Still Barred From Selling Notified Trucks
NHTSA notes that any decision on Mack's petition would not relieve vehicle distributors and dealers of the legal prohibition on the sale, offer for sale, or introduction into interstate commerce of the noncompliant vehicles that are under their control after Mack notified them the noncompliance existed. In short, dealers who are notified by Mack after the company learned of the issue cannot lawfully sell those affected trucks.
