Owner report 11609421 · 2024-08-19 (August 19, 2024)

The BrakeSync valve is located too close to the turbo charger. In hot weather and slow traffic or high engine load as when climbing long grades enough heat builds up to cause the high pressure hose from the air supply tank to the regulator valve to blow.

Recall history

6 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

21V069000 · Service Brakes, Hydraulic:Foundation Components:Disc:Caliper

Reported: 2021-02-12 (February 12, 2021)

Newmar Corporation (Newmar) is recalling certain 2021 Kountry Star and Ventana motorhomes. One of the six brake caliper mounting bolts on the driver side steer axle may have been incorrectly tightened.

Consequence: The loose bolt could result in the loosening of other caliper bolts. Insufficiently tightened bolts may not provide adequate clamping force between the brake caliper and brake anchor plate, resulting in reduced brake effectiveness, increasing the risk of a crash.

Remedy: On behalf of Newmar, DTNA will coordinate the recall repair and notify owners, and dealers will inspect and repair as necessary, free of charge. The recall began on April 12, 2021. Owners may contact Newmar customer service at 1-800-731-8300. Newmar's number for this recall is 21V-018.

21V082000 · Exterior Lighting:Brake Lights:Switch

Reported: 2021-02-17 (February 17, 2021)

Newmar Corporation (Newmar) is recalling certain 2021 Kountry Star and 2017-2021 Dutch Star motorhomes. The brake light switch may chafe against the windshield wiper mechanism, which could damage the brake light switch or it's wiring, and cause the brake lights to not illuminate.

Consequence: If the brake lights do not illuminate, other motorists will be unaware of the driver's intention, increasing the risk of a crash.

Remedy: Newmar will notify owners, and dealers will inspect the brake light switch and replace it as necessary, free of charge. The recall began on April 12, 2021. Owners may contact Newmar customer service at 1-800-731-8300.

21V542000 · Steering:Linkages:Tie Rod Assembly

Reported: 2021-07-20 (July 20, 2021)

Newmar Corporation (Newmar) is recalling certain 2021-2022 Kountry Star and 2021 Ventana motorhomes. The tie rod clamps may be loose, which could result in loose tie rod ends that could break or detach.

Consequence: Detached or broken tie rod ends can result in steering loss, increasing the risk of a crash.

Remedy: Dealers will replace the tie rod clamp bolts and nuts, free of charge. Owner notification letters were mailed on February 9, 2022. Owners may contact Newmar customer service at 1-800-731-8300. Newmar's number for this recall is FL-888.

21V571000 · Equipment:Recreational Vehicle/Trailer | Structure

Reported: 2021-07-27 (July 27, 2021)

Newmar Corporation (Newmar) is recalling certain 2019-2021 Bay Star, Ventana, New Aire, 2019-2020 Canyon Star, Bay Star Sport, Essex, King Aire, London Aire, Mountain Aire, 2018-2021 Dutch Star, 2020 Kountry Star, and 2019 Ventana LE recreational vehicles. The adhesive that bonds the vented portion of the window may fail.

Consequence: Adhesive failure may cause the vent portion of the window to detach, increasing the risk of a crash or injury.

Remedy: Dealers will inspect the windows, and replace the vent if necessary, free of charge. Owner notification letters were mailed on September 10, 2021. Owners may contact Newmar customer service at 1-800-731-8300. Newmar's number for this recall is 21E 047.

22V166000 · Steering:Critical Fasteners

Reported: 2022-03-17 (March 17, 2022)

Newmar Corporation (Newmar) is recalling certain 2021-2022 New Aire, Essex, King Aire, Ventana, Kountry Star, London Aire, Dutch Star and Mountain Aire motorhomes. The upper bolt connecting the steering column may not have been properly tightened, causing the nut to loosen off the bolt, potentially resulting in loss of steering control.

Consequence: Loss of steering control increases the risk of a crash.

Remedy: Dealers will inspect and tighten the upper and lower bolts as necessary, free of charge. Owner notification letters were mailed on May 16, 2022. Owners may contact Newmar's customer service at 1-800-731-8300.

22V234000 · Seats

Reported: 2022-04-11 (April 11, 2022)

Newmar Corporation (Newmar) is recalling certain 2019-2022 Bay Star, Bay Star Sport, Ventana, Dutch Star, New Aire, Canyon Star, 2019 Ventana LE, 2020-2022 Kountry Star, 2019-2020 Mountain Aire, London Aire, Essex, and 2021 Super Star vehicles. The wiring under the seats may be incorrectly secured, which can lead to a pinched wire in the seat adjustment mechanism and cause an electrical short circuit.

Consequence: A short circuit increases the risk of a fire.

Remedy: Dealers will inspect and secure the wiring, adding circuit breaker and fuse protection as necessary, free of charge. Owner notification letters are expected to be mailed on June 10, 2022. Owners may contact Newmar's customer service at 1-800-731-8300.

ODI 11471882

Four times since taking possession of this 2022 RV, a red warning was displayed on the screen saying “Park Brake Not Set”. This requires the operator to insure the brake is actually set, chock tires and act to prevent movement. This exposes the operator and those nearby to potential injury or death. In addition, the “Steering Effort Control Disabled” yellow warning appears with the previous warning. Freightliner and Newmar states that a red warning requires immediate corrective action. While this problem has not been confirmed by a dealer or …

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
