Get a Third-Party Inspection Before You Sign
Pre-delivery inspections (PDIs) conducted by professional RV inspectors are your strongest leverage before you hand over funds. Dealers often promise to “take care of issues after delivery,” but many consumer complaints describe rigs sitting at dealerships for weeks or months awaiting parts or factory authorization. Meanwhile, camping plans get canceled and the unit depreciates while parked.
- Hire a licensed, third-party RV inspector to perform a deep PDI; search for local options: RV Inspectors near me
- Ask for water intrusion testing (including a “rain test”), thermal imaging for insulation/air leaks, and a full operational test of the lithium power system, inverter/charger, alternator charging, HVAC on battery, and all 12V/120V circuits.
- Document every defect on a signed punch list before funds are released; make corrective work a condition of delivery.
- Refuse to accept the unit if critical faults remain unresolved; your negotiating power sharply decreases once the deal is funded.

Model Overview: Entegra Coach Ethos LI
The Ethos LI is a ProMaster-based Class B positioned as an “off-grid” trim with a factory lithium system designed to run air conditioning and essentials without a traditional generator. Owners are attracted to its compact dimensions, ease of driving, and advertised boondocking capability. However, owner-sourced documentation across forums and reviews indicates recurring shortcomings in how the electrical system, build quality, and after-sale service perform in practice.
For background research, compare discussions and issues in the broader Entegra Class B/van market: YouTube: Entegra Coach Ethos LI Issues and Google: Entegra Coach Ethos LI Issues. Also consider safety and recall checks through NHTSA by VIN: NHTSA recall search: Entegra Coach Ethos LI.
Build Quality and Delivery Defects
Cabinetry, Hardware, and Fitment Problems
(Moderate Concern)
Multiple owner reports describe brand-new Ethos LI units arriving with misaligned cabinet doors, loose latches, and trim that detaches in transit. Screws backing out, rattles, and warped panels appear in early owner reviews and forum threads. These issues aren’t unique to Entegra, but the Ethos LI is a premium-priced van; consumers reasonably expect better QC at this price point.
- Before delivery, open/close every cabinet and drawer at least 10–20 times; look for rubbing, binding, and latch misalignment.
- Scan complaint threads and owner photos here: Good Sam: Ethos LI cabinet problems and Google: fit-and-finish complaints.
Water Intrusion: Roof, Windows, Rear Doors, and Plumbing
(Serious Concern)
Water leaks are among the most expensive RV failures. Owners have reported leaks around roof penetrations (A/C, fans, racks), window seals, and rear/side doors—issues that sometimes surface within the first months of ownership. Some complaints describe wet-bath plumbing seepage and loose PEX connections, adding to moisture risks. These are not trivial; mold, delamination, and damaged insulation add cost and downtime.
- Evidence and troubleshooting discussions: Reddit r/rvs: Ethos LI water leaks, RVInsider: water intrusion mentions, Google: water leak problems.
- Insist on a pressure-hose “rain test” during your PDI; check for moisture with a meter. If the dealer refuses, reconsider the purchase.
Electrical and Control System Gremlins
(Serious Concern)
Class B vans pack a lot of electrical complexity into small spaces. Owners describe intermittent failures of control panels, lights, 12V circuits, or inverters, sometimes tied to wiring harness strain and connectors that loosen with vibration. “Phantom drains” and parasitic loads can deplete batteries unexpectedly.
- Search examples and DIY fixes: r/RVLiving: Ethos LI electrical problems, Good Sam: electrical issues.
- During PDI, run every circuit under load: inverter on/off, shore power, alternator charging, lights, fans, fridge, microwave, and rooftop A/C on battery if equipped to do so. Log voltage sags and any error codes.
Lithium Power System: A/C Runtime Claims vs. Reality
Air Conditioner Runtime Shortfalls on Battery
(Moderate Concern)
Marketing for lithium-equipped vans often touts “hours of A/C off-grid.” Owner reports frequently describe shorter-than-expected runtime due to ambient temperature, state-of-charge limitations, inverter inefficiencies, or battery management system (BMS) protections. Ethos LI buyers should insist on a live test: fully charge the system, then run the A/C on battery in sun and heat while logging the hours to automatic shutoff.
- Cross-check claims with owner testing: YouTube: Ethos LI battery A/C runtime, Google: Ethos LI lithium A/C runtime.
Battery Management System (BMS) Faults and Shutdowns
(Serious Concern)
Reports across Class B lithium platforms include sudden BMS shutdowns under heavy load, cold-weather charge lockout, and systems refusing to accept charge after tripping a protection threshold. If the Ethos LI’s BMS trips, owners can face non-start conditions for house systems and long service delays if diagnosis requires factory approval.
- Owner experiences and troubleshooting: r/rvs: Ethos LI lithium problems, Good Sam: lithium issues.
- Ask for component-level documentation at purchase (battery brand/model, inverter/charger specs, DC-DC alternator charger ratings) and warranty terms for these parts specifically.
Alternator/Under-Hood Generator and Charging Reliability
(Serious Concern)
Alternator-based charging systems in vans can overheat under sustained loads or derate in hot weather, leading to slow recharge times and frustrated owners. Some report charging errors while driving or incomplete charges after long drives. If the Ethos LI relies on alternator-heavy charging, confirm real-world performance.
- Search owner notes: Google: alternator charging problems, r/RVLiving: charging issues.
- Have your inspector measure amperage at various RPMs and temps; validate charge curves against spec sheets.
For broader consumer education on lithium pitfalls and verification testing, see these buyer-beware segments by Liz Amazing and then search her channel for terms like “lithium,” “A/C runtime,” and “inspection.”

Chassis and Safety: Ram ProMaster Platform Considerations
Recall Awareness and VIN Checks
(Moderate Concern)
The Ethos LI sits on the Ram ProMaster. Stellantis (Ram) has issued various recalls in recent model years (e.g., camera display, airbags, drivability issues on certain VIN ranges). Not every Ethos LI is affected, but buyers should treat recall diligence as mandatory. Verify recall status by VIN before delivery and re-check periodically.
- Start here: NHTSA recall search: Entegra Coach Ethos LI and also run the chassis VIN directly on NHTSA’s lookup.
- Owner chatter about ProMaster quirks: r/rvs: ProMaster chassis issues (use for general chassis knowledge).
Handling, Braking, and Payload Margins
(Moderate Concern)
Class B conversions push chassis GVWR limits. Owners sometimes report crosswind sensitivity, body roll, brake wear, and tire load ratings close to max, especially after adding gear. Confirm that your chosen Ethos LI floorplan leaves adequate cargo carrying capacity (CCC) for passengers and equipment, and consider suspension upgrades if needed.
- Research owner feedback: Google: Ethos LI payload capacity issues.
Plumbing, Tanks, and Wet-Bath Practicality
Tank Sensor Accuracy and Macerator/Drain Failures
(Moderate Concern)
RVs notoriously struggle with tank sensor accuracy. Ethos LI owners echo common complaints: sensors stuck “full,” macerators that clog or fail, and odors from venting issues. While not unique to Entegra, the downtime and mess can be disproportionately disruptive in small vans.
- Owner reports and fixes: r/RVLiving: tank sensor problems, Good Sam: macerator issues.
Wet-Bath Leaks and Ventilation
(Moderate Concern)
Van wet baths can leak at seams, shower pans, or fixtures if QC was rushed. Poor ventilation can also leave lingering moisture and odors. Carefully test the wet-bath door, caulking, showerhead, and drain. Run the vent fan with the bathroom door closed and inspect for condensation.
- See what owners are posting: Google: wet-bath leaks.
HVAC, Heating, and Noise Concerns
Rooftop A/C Noise, Cycling, and Battery Draw
(Moderate Concern)
Small interior volumes magnify HVAC noise. Owners sometimes report the A/C cycling frequently, tripping on startup surges (if paired with undersized inverters or without soft-start modules), or draining the battery faster than expected. Validate the A/C model specs, startup surge requirements, and whether a soft-start is installed or supported.
- Community experiences: r/rvs: A/C noise, YouTube: A/C problems.
Furnace/Combi Heat Reliability and Winterization
(Moderate Concern)
Reports in van forums reference furnace lockouts, propane delivery issues, and failures to ignite in cold weather. If the Ethos LI uses a combi heater for heat/hot water, maintenance and descaling become essential. Cold-weather charging protections in the lithium system can also limit operation unless heaters are installed for the batteries.
- Search threads and owner fixes: Good Sam: furnace problems, Google: winter camping issues.
Warranty Service, Parts Delays, and Dealer Challenges
Long Repair Timelines and Communication Breakdowns
(Serious Concern)
The most consistent, damaging theme in consumer complaints is prolonged service time. Owners report weeks to months waiting for parts, factory approvals, or dealer appointments—resulting in lost camping seasons and loan payments on an unusable rig. Some claim that after the check clears, communication wanes and their RV languishes on a lot while they wait.
- Review patterns in complaints and timelines: BBB: Entegra Coach Ethos LI (also browse Jayco/Entegra listings), Google: warranty problems.
- Practical tip: Document every service interaction in writing. If you must leave the van, remove valuables and photograph interior/exterior condition on drop-off and pickup.
Industry watchdog content can provide strategies to shorten service timelines and assert your rights; see Liz Amazing’s consumer advocacy videos and then search her channel for “dealer,” “warranty,” and “service delays.”

Recalls and Official Safety Actions
Recalls are official and searchable by VIN. Even if the Ethos LI itself isn’t subject to a body-related recall, the Ram ProMaster chassis could be. Always run your VIN at delivery and periodically afterward.
- NHTSA recall search for Entegra Coach Ethos LI
- Also search by chassis VIN and year; scan recall descriptions for camera, airbag, braking, or electrical-system items.
- For owner reports tied to safety concerns: Reddit recall discussions, YouTube recall overviews.
Price, Options, and Value Depreciation
Premium Pricing and Lithium Package Cost vs. Benefit
(Moderate Concern)
The Ethos LI’s lithium package commands a premium. If A/C runtime, charging performance, and serviceability don’t meet your needs, the upcharge may not pay off. Buyers who expected “generator-like” performance from the battery/inverter system often report disappointment—especially in high heat or when service is required.
- Research price-to-performance comments: Google: Ethos LI overpriced, YouTube: value reviews.
- Ask for detailed, written specs and a live demo of each major claim (A/C runtime on battery; alternator charge rate; solar contribution under cloud cover).
Legal and Regulatory Warnings
While we cannot provide legal advice, owners should be aware of several avenues and obligations:
- Magnuson-Moss Warranty Act (federal): Manufacturers must honor written warranties and cannot require you to use specific branded parts/services unless provided free of charge. Repeated failed repair attempts on the same defect may strengthen claims.
- State “Lemon Laws” and UCC protections: Some states cover RVs; others cover only the chassis or exclude motorhomes. Keep meticulous records (dates out of service, repair orders, communications). Research your state’s rules and thresholds for “days out of service” and “reasonable number of attempts.”
- Federal Trade Commission (FTC): Misleading advertising of features (e.g., off-grid runtime claims) can be actionable. Keep copies of brochures and sales communications.
- National Highway Traffic Safety Administration (NHTSA): Safety defects should be reported. Clusters of similar reports can trigger investigations or recalls. Use the VIN lookup to verify recall completion.
- Better Business Bureau (BBB) and Attorney General complaints: Documenting unresolved issues can pressure resolution and create a record for others. Start here: BBB search for Entegra Coach Ethos LI.
If a dealer refuses timely repairs or the manufacturer delays parts arbitrarily, written demand letters referencing warranty obligations and your state’s lemon law timelines can be effective. Keep all correspondence professional, dated, and in writing.
Product and Safety Impact Analysis
- Electrical/Lithium faults: Risk of system shutdown mid-trip, loss of refrigeration/medications, and unsafe heat exposure if A/C is a medical necessity. Battery or wiring failures can present fire hazards if improperly fused or installed.
- Water intrusion: Hidden structural damage, mold, and electrical shorts. These can rapidly cascade into multi-thousand-dollar repairs and significant downtime.
- Chassis-related recalls: Defects in airbags, cameras, or brakes are direct safety hazards. Failure to complete recalls puts occupants and others at risk.
- Service delays: Financial harm from payments on an inoperable unit, lost use, canceled travel, and potential depreciation. Documented patterns of delays increase risk for new buyers.
In short, the most serious consumer risks center on water intrusion and lithium/electrical reliability, amplified by slow warranty resolution. These are solvable problems—but they require rigorous pre-delivery testing and a responsive dealer-manufacturer pipeline. Without those, buyers bear disproportionate risk.
Action Plan: How to Protect Yourself
- Hire an independent inspector before delivery: RV Inspectors near me. Ask for a written report and negotiate repairs pre-funding.
- Demand a live lithium/A-C runtime test: Fully charge the system. Run the A/C in the afternoon sun. Log start and shutdown times and any error codes.
- Run a water intrusion test: Pressure hose the roof, windows, doors, and seams. Use a moisture meter inside. Inspect underbed/storage areas for dampness.
- Verify recalls by VIN at NHTSA: Have the dealer provide proof of completion for the chassis and coach components as applicable.
- Confirm payload (CCC): Weigh the vehicle as delivered with full fluids. Ensure usable capacity remains for passengers and gear.
- Get every promise in writing: A/C runtime claims, charging rate specs, parts availability timelines, and any dealer addendums.
- Build a paper trail: Keep a binder with invoices, service orders, emails, and dated photos. This is essential for warranty and potential lemon law actions.
