Initial Quality Concerns Surface Quickly
Our long-term evaluation of the 2025 Toyota 4Runner TRD Off-Road Premium encountered unexpected service needs within just two months of ownership. While Toyota's reputation for reliability precedes it, our experience highlighted two specific issues that required dealership attention: a problematic moonroof seal and a damaged front air dam. These early challenges provide valuable insights for potential buyers about real-world ownership experiences with this popular SUV.

Key Findings at a Glance
- Moonroof leaked during high-pressure car wash despite no issues in rain
- Front air dam broke unexpectedly with no identifiable cause
- Dealer service experience was efficient but diagnostic opinions differed
- Replacement air dam costs $750 for just the part
- Hybrid powertrain efficiency may be affected by missing air dam
The Moonroof Leak Mystery
Car Wash Reveals Design Flaw
During a routine visit to a touchless car wash, we discovered water intrusion from the moonroof's rear passenger side. The high-pressure streams caused light spraying inside the cabin—an issue we hadn't experienced in other vehicles at the same facility. Interestingly, normal rain exposure didn't produce similar leakage, suggesting the problem relates specifically to concentrated high-pressure water application.
Dealer's Surprising Assessment
Toyota service technicians claimed this behavior was "normal" for moonroofs in high-pressure wash environments, citing built-in drainage channels as sufficient protection. Their position was that unless water reached the headliner (which ours didn't), no repair was necessary. This contrasts with our experience across multiple vehicle brands where moonroofs withstand car washes without interior

Owner's Recommendation
If your 4Runner's moonroof leaks during car washes but not in rain, consider switching to hand-washing or low-pressure facilities. The seals may not tolerate certain wash systems' intensity despite dealer assurances of normal operation.
Front Air Dam Failure: Costly Consequences
Unexpected Damage With No Clear Cause
The driver's side edge of our 4Runner's front air dam sheared off without any identifiable impact or off-road use. Staff members who drove the vehicle couldn't recall any incidents that might explain the damage. This suggests either a material weakness or that the component is particularly vulnerable to normal road debris.
Sticker Shock at the Parts Counter
The dealership quoted approximately $750 just for the replacement air dam part—a surprisingly high cost for what appears to be simple molded plastic. This pricing raises questions about the component's actual value versus Toyota's parts pricing strategy for what is essentially an aerodynamic aid.
Replacement Cost Breakdown
- Part Cost: $750 (including taxes)
- Labor Estimate: $150-$300 if done by dealer
- DIY Difficulty: Moderate (requires basic tools and ramp/jack stands)
- Fuel Economy Impact: Estimated 0.5-1.5 MPG loss without air dam
Dealership Service Experience
Streamlined Digital Scheduling
The Toyota app provided an efficient service scheduling experience—a notable improvement over some competitors' systems. Features like dealer selection, issue description, and text confirmations created a seamless process from appointment booking to arrival.

Service Advisor Interactions
While the digital experience excelled, the in-person service consultation revealed some disconnects. The technician's dismissal of the moonroof leak as "normal" despite our concerns demonstrates how dealerships sometimes prioritize manufacturer guidelines over owner experiences. This highlights the importance of advocating for your concerns during service visits.
Dealer Service vs. Independent Repair
| Factor | Dealership | Independent Shop |
|---|---|---|
| Parts Availability | Direct access to OEM parts | May need to order |
| Technical Knowledge | Brand-specific training | Varies by shop |
| Cost | Typically higher | Often 20-40% lower |
Owner-Approved Solutions and Future Plans
Moonroof Workaround
We've adopted these practical solutions for the moonroof issue:
- Avoiding high-pressure touchless car washes
- Regularly cleaning and inspecting moonroof seals
- Applying UV-protectant to prevent seal degradation
Air Dam Replacement Strategy
Our approach to the air dam situation involves:
- Attempting DIY installation when the part arrives
- Documenting the process for future owner reference
- Monitoring fuel economy changes pre- and post-repair
- Considering permanent removal if it fails again

Mechanical Perspective
"Front air dams on modern SUVs serve multiple purposes beyond aerodynamics," explains our lead technician. "They often direct airflow for brake cooling and engine compartment ventilation. While short-term removal won't cause harm, long-term deletion might affect these secondary systems."
Long-Term Implications for 4Runner Owners
These early service experiences reveal important considerations for 2025 4Runner buyers:
Build Quality Observations
The moonroof and air dam issues suggest certain components may not meet Toyota's traditional durability standards. Potential buyers should:
- Thoroughly test moonroof seals during purchase inspection
- Examine front underbody components for vulnerability
- Consider extended warranty coverage for peace of mind
Cost of Ownership Factors
Our $750 air dam replacement highlights that even rugged SUVs can have surprisingly expensive repair costs for seemingly minor components. Budget-conscious buyers should:
- Research parts pricing for common wear items
- Factor in potential out-of-warranty repair costs
- Consider DIY repair capabilities for basic maintenance
Comparative Reliability Analysis
How does the 2025 4Runner's early reliability compare to competitors?

Segment Expectations
Midsize SUV buyers typically expect:
- 3-5 years before significant repairs
- Minimal interior component issues
- Durable exterior trim pieces
Competitor Performance
Compared to rivals like the Ford Bronco and Jeep Wrangler:
- The 4Runner's issues are less severe than common Bronco roof leaks
- Wranglers typically experience more frequent minor issues
- Both competitors have more reported electrical gremlins
Preventative Maintenance Recommendations
Based on our experience, we recommend these proactive measures for 2025 4Runner owners:
Moonroof Care
- Clean tracks and drains quarterly
- Inspect seals every oil change
- Apply silicone lubricant to seals biannually
- --SECOND CONTENT ADVERTISEMENT HERE--
Front Air Dam Preservation
- Inspect mounting points monthly
- Reinforce attachment points with washers
- Consider aftermarket aluminum alternatives
Final Assessment and Owner Advice
While these early issues haven't diminished our overall appreciation for the 4Runner's capabilities, they serve as important reminders that even the most reliable brands can have model-specific quirks. Our key takeaways for prospective buyers:
- Test thoroughly: Specifically evaluate moonroof seals and underbody components
- Budget accordingly: Some repairs may cost more than expected
- Document issues: Create a service paper trail for potential warranty claims
- Consider alternatives: Research whether competitors better suit your needs
We'll continue monitoring these issues throughout our long-term test, providing updates on any developments or additional concerns that arise. For current 4Runner owners experiencing similar problems, we recommend joining owner forums to share solutions and pressure Toyota for improved resolutions.
