- Summary
- Chrysler (FCA US LLC) is recalling certain 2018 RAM 4500 and 5500 cab chassis trucks. The primary and secondary brake hoses located between the brake master cylinder and the hydraulic control unit may have been manufactured without anti-corrosion plating on the ferrules, which can allow the ferrules to corrode.
- Consequence
- If the ferrules corrode, the brake fluid may leak and cause a loss of braking, increasing the risk of a crash.
- Remedy
- Chrysler will notify owners, and dealers will inspect the brake hoses and replace them if necessary, free of charge. The recall began June 19, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U41.

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your Ram been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. Recall repairs are free.
