The Shyft Group has initiated a recall for 836 Spartan RV Chassis designed for Class A motorhomes due to a component failure that causes the brake lights to stay illuminated even when the brakes are not engaged.
The manufacturer believes that all 836 units involved in this campaign contain the defect, which violates the Federal Motor Vehicle Safety Standard 108 governing vehicle lamps, reflective devices, and related equipment, according to an article by The Break Report.
This issue stems from a normally-closed, single-pole single-throw pressure switch within the air brake system, specifically identified as part number 0108-GG3-031.
The root cause of the problem is that the switch can hold onto residual air pressure after the driver releases the service brake, a flaw attributed to the lack of a specified minimum release pressure when the component was originally chosen.
Since there is no dashboard warning alerting the driver to the stuck lights, trailing motorists can easily become confused regarding the motorhome’s speed and the operator’s intentions, creating an increased risk of a collision.
This compliance failure mirrors other recent stop-lamp and braking issues reported by The BRAKE Report, such as a Ford Hydroboost defect affecting F-59 and F-53 stripped chassis, along with an earlier Shyft parking-brake recall involving its Blue Arc electric transport trucks.
To address this safety hazard, Shyft will provide a free replacement of the defective pressure switch.
The upgraded component, which the company integrated into its production line last fall, features a precise pressure setting that ensures the brake-lamp circuit only closes when the service brake is actively pressed.
Under the phased recall program identified by the manufacturer as campaign 26-05 and by the NHTSA as campaign 26V292, owner notification letters are slated to be sent out on June 5, 2026.
Affected customers can direct their inquiries to Shyft’s customer service department by calling 1-800-237-7806.
The recall encompasses specific K1, K2, K3, and K4 chassis lines spanning the 2024 through 2027 model years, with production dates ranging from August 2023 to October 2025.
The company located the impacted population by executing a where-used system query for the faulty switch.
For the K1 series, the recall involves seven units from the 2025 model year manufactured between January 29, 2024, and April 23, 2024.
The K2 chassis population includes 106 units from the 2024 model year built between November 30, 2023, and December 26, 2025.
It also covers 168 K2 units for 2025 produced from September 21, 2023, to March 3, 2025, and another 67 units for 2026 assembled between October 16, 2024, and September 29, 2025.
For the K3 chassis line, the campaign impacts 149 units from the 2024 model year constructed between September 20, 2023, and June 17, 2024.
An additional 149 units from the 2025 model year built between August 31, 2023, and May 13, 2025, are included, alongside 121 units for 2026 that rolled off the line from October 10, 2024, to September 11, 2025.
Finally, the K4 chassis recall involves 26 units from the 2025 model year produced from October 12, 2023, to July 23, 2024.
It also affects 33 K4 units for 2026 built between June 26, 2024, and July 25, 2025, and 10 units for the 2027 model year manufactured between June 26, 2025, and October 16, 2025.
For the recreational vehicle industry, this recall underscores the critical nature of supply chain quality control, particularly within the premium Class A motorhome segment.
