2022-2024 Rivian R1S Floor Mats: Fitment Issues and Critical 2025+ Incompatibility
Learn about common OEM mat fitment problems, top aftermarket alternatives, and the crucial safety warning about using these mats in 2025 or newer R1S models.
- NEVER use a 2022-2024 floor mat in a 2025 or newer R1S due to a floor redesign that can cause accelerator pedal interference.
- When buying used mats, the most critical inspection is checking that the retention clip holes are not torn or damaged to prevent dangerous sliding.
- The front driver and passenger mats are interchangeable with the R1T, but the rear mats are specific to the R1S.
- Many owners report fitment issues like bulging with OEM all-weather mats and often prefer aftermarket brands like 3D MAXpider or WeatherTech for better coverage.
Critical Safety Warning: 2025+ Model Year Incompatibility
Warning: Do NOT install 2022-2024 (Gen 1) floor mats in a 2025 or newer (Gen 2) Rivian R1S. Rivian redesigned the driver-side floor area for the 2025 model year. Using an older mat in a newer vehicle can cause the mat to interfere with the accelerator pedal, potentially causing it to become stuck. This creates a significant risk of unintended acceleration. Always purchase the correct mat for your specific model year.
Symptoms of Worn-Out Floor Mats
While seemingly simple, a worn-out floor mat can range from a cosmetic annoyance to a genuine safety hazard. Here’s what to look for:
- Sliding or Shifting: The most dangerous symptom. If the mat moves under your feet, it means the anti-skid backing is worn or the retention points are broken. A sliding driver's mat can bunch up under the pedals.
- Curling or Warped Edges: Mats, especially all-weather rubber types, can curl at the edges over time due to heat cycles. This creates a tripping hazard for passengers and can prevent the mat from sitting flat.
- Cracks, Holes, or Tears: The driver's mat is most susceptible to wear under the heel. A hole will allow water and dirt to reach the carpet, defeating the mat's purpose. Cracks in rubber mats can catch on shoes and worsen quickly.
- Flattened Edges: All-weather liners have a raised lip to contain spills. If this edge is broken or flattened, it can no longer hold liquid, allowing water or snowmelt to saturate the vehicle's carpet.
Buying a Used 2022-2024 Rivian R1S Floor Mat
Buying a used set of OEM all-weather mats can be a good way to save money, but a thorough inspection is essential. Focus on function and safety over minor cosmetic blemishes.
Inspection Checklist:
- Check Retention Points: This is the most critical check. The driver's mat has holes that lock onto posts on the floor. Inspect these holes for any signs of tearing, stretching, or cracking. A compromised retention point means the mat will not stay securely in place.
- Examine the Driver's Heel Area: This spot sees the most action. Look for excessive wear, deep grooves, or thinning material. While some scuffing is normal, avoid any mat that is close to wearing through.
- Flex the Mat: Bend and twist the mats, especially all-weather rubber types. This will reveal any brittleness or hidden cracks that aren't visible when the mat is lying flat.
- Verify the Edges: Ensure the raised perimeter lip is intact and not broken, torn, or permanently folded down. Its ability to contain spills is a key feature.
- Confirm R1S Specificity: While the front driver and passenger mats are the same for the R1T and R1S, the second and third-row mats are unique to the R1S. Ensure you are buying a set from an R1S to guarantee fit for the rear of the vehicle.
Common Owner Complaints & Fitment Issues
As of mid-2026, there are no official recalls from Rivian or the NHTSA for floor mats on the 2022-2024 R1S. However, owner forums are filled with discussions about common fitment issues with the OEM all-weather mats.
- Passenger & Second Row Bulging: Many owners report that the front passenger mat and the large, one-piece second-row mat do not lie perfectly flat. A crease or bulge can form, particularly near the center console or door sills.
- Inadequate Coverage: A common complaint is that the OEM mats offer less coverage than aftermarket alternatives, leaving carpet exposed along the sides and under the pedals.
- Potential Cause: In some instances, owners have discovered that poor mat fit was caused by misaligned interior trim panels from the factory. A service visit to adjust the trim sometimes resolved the issue, allowing the mat to sit properly.
OEM vs. Popular Aftermarket Options
Many owners opt for aftermarket mats to address the perceived shortcomings of the OEM versions. Brands like 3D MAXpider, WeatherTech, and TuxMat are frequently recommended by R1S owners for their superior coverage and fit.
| Brand | Material | Key Feature | Reported Pro/Con |
|---|---|---|---|
| Rivian OEM | Eco-Rubber | Guaranteed compatibility with retention posts. | Pro: Factory look. Con: Fitment issues and incomplete coverage reported by some users. |
| 3D MAXpider Kagu | Thermoplastic Rubber w/ Foam Core | Patented anti-skid bottom layer that grips carpet without damaging it. | Pro: Excellent fit and coverage, modern look. Con: Can be more expensive. |
| WeatherTech FloorLiner | Thermoplastic Elastomer (TPE) | Laser-measured for a precise fit with high side walls. | Pro: Very durable and great at containing spills. Con: Some users find the material too hard or slippery when wet. |
| TuxMat | Multi-layer (Vinyl top, EVA core) | Maximum vertical coverage, extending up the sides of the footwell. | Pro: Unmatched coverage area. Con: Fabric-like appearance may not be for everyone. |
Cost Comparison: 2022-2024 R1S Floor Mats
| Type | Price Range | Notes |
|---|---|---|

| New Aftermarket | $160 - $350 | Price varies by brand and coverage (e.g., front only vs. full set). |
| Used OEM | $100 - $180 | Dependent on condition. Check eBay and Rivian owner forums. |

Installation
Replacing floor mats is a simple task that requires no tools and can be done in minutes.
- Remove the old floor mats from the vehicle.
- Vacuum the carpet underneath to remove any dirt or debris.
- Place the new driver's side mat in the footwell, making sure to align the holes in the mat with the vehicle's built-in retention posts on the floor.
- Press down firmly over the posts to lock the mat in place. You should feel a distinct click or snap.
- Repeat the process for the passenger side and lay the rear mats in place, ensuring they are flat and properly positioned.
Pro Tip: New all-weather mats are often folded or rolled for shipping. If they don't lay flat immediately, leave them in a warm, sunny spot for an hour. The heat will soften the material, allowing them to settle into their correct shape.
Frequently Asked Questions (FAQ)
Do 2022-2024 R1T mats fit a 2022-2024 R1S?
Partially. The front driver and passenger mats are identical and can be swapped between the R1T and R1S of the same model years. However, the second-row and third-row mats are completely different and are not interchangeable.
Will 2022-2024 mats fit a 2025 or newer R1S?
No, and it is dangerous to try. The floor pan was changed for the 2025 model year. Using an older mat in a new R1S can cause accelerator pedal interference.
How do I clean the all-weather mats?
For a quick clean, you can wipe them down in the vehicle. For a deep clean, remove them, shake out loose debris, hose them down with water, and use a mild soap and a soft brush if needed. Let them air dry completely before reinstalling.
