TIFFIN Complaints

Several times over the last 10 months (since I’ve owned this), the drivers side slide creeps out on its own, pushing and bending the drivers seat. This is a common problem on most 2022 Ans some 2021 RVs withe the lippert hydraulic system.

THE LIPPERT HYDRAULIC SLIDES ON THE DRIVER AND PASSENGER SIDE WILL OPEN WHILE GOING DOWN THE ROAD AND/OR EXPRESSWAY. WE HAVE HAD IT LOOKED AND NUMBERIOUS TIMES AT TIFFIN MOTOR HOMES IN RED BAY, ALABAMA AND NORTH TRAIL RV IN FORT MEYERES, FLORIDA. ALSO LIPPERT COMPONENTS , CHRISTOPHER PONTIUS AT LIPPERT HAS REVIEW MY CASE # 308-5947. WE BOUGHT OUR RV IN OCTOBER OF 2021 THEY HAVE NOT COME UP WITH A FIX AS OF YET. IN A BLOG THIS ISSUE HAS BECOME A SAFETY CONCERN WHICH COULD CAUSE A SERIOUS ACCIDENT AND LEAD TO DEATH WHILE TRAVELING.

The contact owns a 2020 Tiffin Allegro Bus. The contact stated that while operating the vehicle the odor of diesel fuel was present inside the motorhome. Upon inspection it was discovered that the diesel fuel was leaking from the high pressure fuel rail onto the reburner causing smoke to be present. The fire dept was call to the scene but no action was needed. The vehicle was towed to the local service center who diagnosed that the high pressure fuel rail was faulty and needed to be replaced. The contact indicated that the vehicle was previously serviced under the NHTSA recall campaign number 21v306000(fuel system) for the same failure but after the recall repair the same failure had occurred. The failure mileage was 15,000.

The contact owns a 2020 Tiffin Allegro Bus. The contact received a notification for NHTSA Campaign Number: 21E320000 (Fuel System, Diesel). The dealer had been notified about the recall and informed him that if the fuel rails were stable upon inspection of the vehicle, they could make needed reinforcements and return the vehicle; however, if the fuel rails needed replacement, the vehicle would have to remain in the dealer's possession until parts became available. The manufacturer had been notified of the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the repair. The contact had not experienced a failure. Parts distribution disconnect.

The Lippert slides which are normally expanded for use when the vehicle is parked for camping and then retracted when driving, move out and expand on their own while the motorhome is being driven down the road and when it is just parked in storage. Our motorhome has been in the Tiffin repair shop to address the defective slide in February. We were told it was repaired and the issue continued after coming to pick up the vehicle on March 20 with the slide expanding outward about 6 inches in just a few hours. This presents a safety issue when the vehicle is driven as the slide will expand on its own with the driver having no way to control the expansion and keep the slide from moving outward on its own. Our greatest concern is for the safety of the motorhome passengers with unstable parts and the cars/vehicles in the lanes next to the motorhome when the slides expand randomly while traveling. There is no warning light and no way to know how far the slide may expand. We have read 100s of posts online from owners of 2022 Tiffin motorhomes who have the same issue and have yet to be given a permanent solution to the slides expanding on their own. Lippert needs to provide a permanent and safe solution to the defective slides for the safety of all considered. The attached pictures include before and after pictures to show how much the slide moved in just a couple of hours while parked.

The automatic leveling jacks have lateral support bars, both front and rear. This support bar has been reported numerous times (>20) via social media as having come apart due to very poor welding; and or no weld other than minor tap welds to hold in place. This fault could lead to the motorhome shift downwards rapidly and seriously injuring or killing the occupants accessing the under coach storage and or service compartments, or Should this very large (40 lbs, 6' long) piece of metal detach while the coach is traveling, this road debris could very likely injure and or kill the occupant(s) of a following vehicle.

The contact owned a 2011 Tiffin Phaeton motorhome equipped with Michelin tires, Tire line: Green X, Tire size: 275/80R22.5, and DOT number: M5EJOOEX3815. The contact stated that while driving at 70 MPH, the front passenger's side tire had a blowout, which caused the RV to crash into a utility pole, trees, and then stop after crashing into a fence. The contact and his wife, who was a passenger, were transported by ambulance to the hospital. The contact had a scratch above his eye, while his wife suffered three broken ribs, bruised, and stitches on her arms and legs. A police report was filed. The RV was hauling a double-decker trailer, a 2017 Lincoln MKZ, and a Boston Whaler, which were towed to a tow yard and deemed totaled by the insurance company. The manufacturer was not made aware of the failure. Prior to the failure, the rear passenger's side tire had a blowout and the manufacturer covered half the cost of replacement.

This is in reference to NHTSA #21V-921. We received a recall letter from Daimler Trucks indicating that an inner rear tire support grommet and valve extension needs to be removed due to the possibility that the support grommet will fall out resulting in the potential failure of the inner tire valve extension. Daimler issued a similar recall in 2020 which was related to the same issue but the remedy was to replace and or reinstall the grommet. In our case a service center installed the grommet and used RTV to hold it in place. The recall states that if the grommet is not removed the Owner takes on the liability for a failure. The issue with the removal of the extension and grommet make it impossible to use a cap based tire monitor sensor since the chassis was not equipped with internal tire sensors. This creates another safety issue in that the inner tires cannot be monitored. Daimler has not provided an option to have internal sensors installed along with a means to monitor the pressure.

The contact owns a 2018 Tiffin Allegro Breeze. The contact stated while driving approximately 20 MPH, the air brakes failed due to low air pressure. The contact stated that he was safely able to pull off the road to avoid a crash. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 18E112000 (Engine and Engine Cooling). The contact stated that prior to the recall repair he had not experienced a failure with the vehicle. However, after the repair was completed, he drove 18,000 miles and experienced failure. The contact stated that prior to the brakes locking up, the low air pressure warning light had been illuminated. The contact replaced the fan belt to regain air pressure while pulled over to the side of the road. The vehicle was driven to the dealer and remained at the dealer. The contact was informed that the failure had caused damage to the engine. The manufacturer was not made aware of the failure. The approximate failure mileage was 38,000.

Cruise control disengagement . Abrupt ceasing interferes with anti collision and speed control causing slowing speeds without warning, could be a risk to those following as well disrupting the flow of traffic. The vehicle has been inspected by 3 MB service technicians. 1 .MB of Selma, TX-09/2021 2. MB of Boerne, TX-09/2021 3.
