A new round of Grand Design RV safety notices is reaching owners as three narrowly targeted recalls put attention on tire-pressure information and electrical hazards in some of the company’s newest recreational vehicles. Grand Design’s U.S. filings scheduled owner notifications to begin August 17, 2026, covering certain Lineage motorhomes and Imagine travel trailers.
The campaigns are small in numerical terms, involving 19 potentially affected vehicles across three U.S. recalls, but the hazards are not trivial. One involves incorrect rear-tire pressure information, another concerns wiring that could overheat because of inadequate circuit protection, and a third involves a 120-volt outlet installation that could lead to electrical arcing. For Canadian owners, one of those electrical problems has also been formally documented by Transport Canada.
Three Separate Grand Design Recalls Are Moving at Once
The new notices stem from three different U.S. safety campaigns rather than one large recall. Grand Design is recalling 10 Lineage motorhomes over incorrect tire-pressure information, seven Imagine trailers because of an inverter-prep electrical circuit, and two additional Imagine trailers because of the way a 120-volt outlet cover was secured. Together, that makes 19 potentially affected vehicles in the U.S. campaigns.
That relatively small total could make the recalls easy to overlook, especially for owners accustomed to hearing about automotive campaigns involving tens or hundreds of thousands of vehicles. But recall size does not determine the seriousness of an individual defect. Tire failure can affect vehicle control, while overheated electrical wiring or sustained electrical arcing can create fire hazards. The practical question for an owner is therefore not how large the campaign is, but whether the specific VIN falls within it.
The Lineage Recall Is About the Tire-Pressure Label
The tire-related campaign affects certain 2026 and 2027 Grand Design Lineage motorhomes fitted with the 20-inch wheel and tire package. According to the recall information, the tire-information label can state an incorrect pressure for the rear tires. Ten vehicles are potentially involved under NHTSA campaign 26V491, with Grand Design identifying the campaign internally as M910065.
This is a labeling problem rather than an allegation that the tires themselves were manufactured incorrectly. That distinction matters. Motorhome owners depend on vehicle placards to determine the manufacturer’s specified cold inflation pressures, particularly when carrying passengers, supplies and other loads. If the information on that placard is wrong, a driver following it precisely could still end up operating the tires outside the intended specification. Grand Design’s remedy is therefore focused on correcting the information owners are expected to use.
Too Much Tire Pressure Can Be a Safety Problem Too
Underinflated tires receive considerable attention, but the Grand Design campaign highlights the opposite problem. NHTSA’s recall description says the incorrect label could lead to rear tires being overinflated, increasing the possibility of tire failure and a crash. The affected Lineage motorhomes also fail to meet the labeling requirements associated with Federal Motor Vehicle Safety Standard No. 120.
For an RV owner, the issue is a reminder that the number printed on a vehicle’s tire-information label has a purpose. Motorhomes carry substantial weight, and tire pressure influences how the tire supports that load and behaves on the road. An owner discovering that a Lineage is part of this campaign should therefore rely on the corrected information supplied through the recall rather than attempting to determine a new specification independently. Grand Design says dealers will replace the affected labels without charging owners.
The Tire Recall Fix Is Straightforward
The remedy for the Lineage campaign is comparatively simple: dealers are expected to replace the incorrect tire-information label at no cost. Owner notification letters were scheduled to begin going out on August 17. Grand Design lists its customer-service number as 574-825-9679 for owners seeking information about the recall, while the manufacturer’s campaign number is M910065.
A small repair does not mean the notice belongs at the bottom of an owner’s paperwork pile. A motorhome may travel thousands of kilometres during a summer season, often while carrying substantial cargo and operating for long stretches at highway speed. Correct inflation information becomes particularly important in that environment. Owners of 2026 or 2027 Lineage motorhomes with the 20-inch package can reduce uncertainty by checking the VIN rather than assuming that every vehicle of those model years is affected. The recall applies only to the identified population.
Seven 2027 Imagine Trailers Face an Overheating Risk
A second campaign shifts the focus from tires to the electrical system. Grand Design is recalling seven 2027 Imagine recreational trailers because the conductor serving the inverter-preparation circuit may not have sufficient overcurrent protection. NHTSA identifies the campaign as 26V492, while Grand Design’s internal recall number is 910066.
The problem becomes important when electrical demand exceeds what the circuit can safely handle. Reporting on the recall describes an incorrect breaker in the inverter-prep circuit that may allow the conductor to overheat rather than providing the intended protection. Excessive heat in electrical wiring can damage insulation and surrounding materials, which is why the recall documentation identifies fire as the principal safety risk. Grand Design’s planned correction does not require replacing the trailer’s entire electrical system; dealers are expected to replace the breaker with the proper component, free of charge.
Overcurrent Protection Is the Critical Detail
Circuit breakers are designed to interrupt a circuit when current exceeds an appropriate limit. In the affected Imagine trailers, the concern is that the inverter-preparation circuit does not have the proper protection for its conductor. If an inverter is connected and that circuit is overloaded, the wiring could become excessively hot before the protective device responds as intended.
That makes this recall different from a nuisance electrical problem such as a dead outlet or a tripped breaker. The safety concern involves heat building in wiring, potentially in an area an owner cannot easily monitor. The official recall description says an overheated conductor can increase the risk of fire. Grand Design plans to have dealers replace the breaker at no cost, with owner notification beginning August 17. Owners who believe their 2027 Imagine could be included should have the VIN checked rather than relying solely on model year.
Another Imagine Recall Involves a 120-Volt Outlet
A third Grand Design campaign covers two 2026 Imagine travel trailers in the U.S. The problem is remarkably specific: a cover over a 120-volt receptacle in the front passthrough utility area was secured through the wrong screw locations. That placement can bring a fastener into contact with wiring behind the receptacle.
Grand Design’s filing explains why such a minor assembly detail can become a safety issue. A screw pressing against or penetrating the insulation on an energized 120-volt conductor can create a short circuit or sustained electrical arc. Either condition can generate enough heat to create a fire risk. The two U.S. trailers covered by campaign 26V490 were produced between March 26 and March 30, 2026. Dealers are instructed to inspect the fastener positions and repair the installation when necessary.
Owners May Not See a Warning Before the Outlet Problem Appears
One of the more important details in Grand Design’s NHTSA filing is that the outlet condition may not reveal itself during ordinary use. The affected wiring sits inside the utility-panel area and cannot be inspected normally without removing trim. The manufacturer said there may be no warning indication visible to an owner before the problem is discovered.
There is reassuring context as well. At the time of Grand Design’s filing, the company reported no field failures, warranty claims, property-damage claims, injuries or fires associated with the condition. Its investigation had already led to production holds, repairs to vehicles that had not yet been delivered and a dealer technical service bulletin. The formal recall ultimately followed after Grand Design determined that vehicles requiring correction remained in the field. For owners, that chronology illustrates why recalls can emerge even when no accident has yet occurred.
The 120-Volt Problem Has a Direct Canadian Connection
Canadian Grand Design owners have an especially clear reason to pay attention to the outlet issue. Transport Canada recall 2026370 covers 2026 Imagine RV trailers with a problem involving the 120-volt outlet cover in the front passthrough utility panel. Transport Canada says an improperly installed cover could damage the wiring and lead to a short circuit or electrical arcing.
The Canadian regulator identifies both electrocution and fire as potential safety risks. Grand Design is to notify affected Canadian owners by mail and advise them to take the trailer to a dealership, where the wiring can be inspected and repaired when necessary. The U.S. manufacturer’s chronology provides another notable detail: of four units still requiring repair at one stage of the investigation, two had been built for sale in the United States and two for sale in Canada. Transport Canada’s notice was originally published July 30.
Canadian Owners Should Distinguish U.S. and Canadian Recall Lists
The presence of Canadian-built-for-sale units in the outlet campaign does not mean every new U.S. Grand Design recall automatically applies to vehicles sold in Canada. Recall populations can differ between countries because manufacturers and regulators track vehicles according to market, certification requirements, production records and VIN ranges. The safest approach is to verify the actual Canadian recall record instead of assuming that a U.S. campaign has identical Canadian coverage.
At the time these notices were checked, Transport Canada’s public alert clearly documented the 2026 Imagine 120-volt outlet issue. The U.S. filings separately document the 2026-2027 Lineage tire-label campaign and the 2027 Imagine inverter-prep breaker campaign. Canadian owners concerned about either vehicle should check their VIN with Grand Design and review Transport Canada’s recall information. That prevents a U.S. headline from being mistaken for confirmation that a specific Canadian-market RV is included.
The VIN Is More Useful Than the Model Name Alone
A recall affecting a particular model year does not necessarily include every vehicle wearing that badge. Grand Design provides an online recall lookup that allows owners to search by VIN, while NHTSA offers its own VIN-based recall system for U.S. vehicles. NHTSA also cautions that recently announced recalls can take time to populate completely as manufacturers identify affected VINs.
That matters considerably with these campaigns because the populations are exceptionally narrow. Only 10 Lineage motorhomes are identified in the U.S. tire-label campaign, seven Imagine trailers in the breaker campaign and two Imagine trailers in the U.S. outlet campaign. Someone seeing “2027 Imagine” in a headline therefore should not conclude automatically that every 2027 Imagine needs the same repair. Checking the 17-character VIN with the manufacturer or the appropriate regulator offers a much more reliable answer than relying on model year alone.
A Recall Letter Should Lead to a Dealer Conversation
For affected owners, the remedies are being offered without charge: a corrected label for the Lineage tire campaign, a replacement breaker for the affected 2027 Imagine trailers, and inspection and repair of the outlet installation for the affected 2026 Imagine units. Grand Design’s U.S. recall schedule sets August 17 as the beginning of the owner-notification period, although some notices can be distributed over several days.
The next step is practical rather than complicated. Owners can keep the recall number and VIN available, contact Grand Design or an authorized dealer and confirm what work is required before arranging service. Electrical repairs in particular are better handled through the prescribed recall process than through guesswork around energized circuits. For Canadians, Transport Canada’s database provides an additional official reference point. With RV travel still active during late summer, dealing with a confirmed safety recall promptly can prevent a small production mistake from becoming a much larger problem on the road.
