2022-2026 Rivian R1S Upper Liftgate and Lower Tailgate Hinge Guide
This guide explains the common failure points, part numbers, and replacement nuances for the distinct upper and lower rear hinges on the 2022-2026 Rivian R1S.
- The Rivian R1S has two different hinge sets: one for the upper power liftgate and one for the lower manual tailgate. They are not interchangeable.
- Most common issues are noise and misalignment, which can often be fixed by adjusting the latches or lubricating seals, not by replacing the hinges.
- A Technical Service Bulletin (TSB RSB-56-23-002-1) exists for some 2022 models addressing upper liftgate fit and water leaks.
- Replacing the lower manual tailgate hinges is a moderate DIY job, but replacing the upper power liftgate hinges is difficult and best left to a professional.
Understanding the Rivian R1S Split Rear Door Hinges
The 2022-2026 Rivian R1S is equipped with a two-piece rear door, often called a clamshell or split tailgate. This design uses two separate sets of hinges: one for the upper power-operated liftgate and another for the lower manually-operated tailgate. These hinges are not interchangeable. Before purchasing a replacement, it is essential to identify which set of hinges you need.
Warning: The upper liftgate and lower tailgate use different hinges. Visually inspect the hinges on your vehicle and match them to photos and part numbers to ensure you are buying the correct part for your specific need.
Symptoms of Failing or Misaligned Hinges
Most issues related to the R1S rear hinges are due to alignment rather than catastrophic hinge failure. However, a bent or damaged hinge from an impact can cause these same symptoms.
- Popping, Creaking, or Clicking Noises: A popping or clicking sound when opening or closing the upper liftgate is a common complaint. This can be caused by the liftgate panel making contact with the rear roof applique, especially in hot weather which can cause materials to expand. Creaking can also come from the main liftgate weather seal rubbing against the body, which can often be solved by cleaning and lubricating the seal.
- Poor Alignment or Uneven Gaps: The most frequent issue reported by owners is misalignment of the upper liftgate and/or lower tailgate. This can manifest as the upper liftgate sitting too low relative to the roofline, or uneven gaps between the tailgate and the rear quarter panels. In some cases, the liftgate may rub on the lower tailgate, causing paint damage.
- Difficulty Latching or Closing: Severe misalignment can prevent the liftgate or tailgate from latching securely. You might notice the power liftgate repeatedly trying to close and then popping back open.
- Water Leaks: If the hinges are bent or the door is misaligned, the weather seals may not make proper contact, leading to water entering the cargo area.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While there are no specific recalls for the hinges themselves, several issues related to the rear closure panel are well-documented.
Technical Service Bulletin RSB-56-23-002-1
Rivian issued this TSB for some 2022 R1S models to address complaints of the "Upper Liftgate Body Fit and/or Water Leakage." The issue stems from a liftgate seal flange that was shorter than designed on some early production vehicles. Symptoms include water leaking into the cargo area near the upper liftgate or the liftgate itself contacting the rear roof applique when opened. The service procedure involves adjustments and potentially replacing the liftgate seal. If you have a 2022 R1S with these symptoms, a Rivian service center can check if your vehicle is covered by this bulletin.
Factory Alignment Issues
Many owners of early-build R1S vehicles have reported panel gap and alignment issues from the factory. In many cases, these are not caused by faulty hinges but by the initial factory adjustment of the latches and strikers. Minor alignment problems can often be corrected by adjusting the latch mechanism, a procedure some owners have performed themselves.
Pro Tip: Before assuming your hinges are bad, check for simple alignment issues. A common DIY fix for a liftgate that doesn't close flush is to slightly loosen the three bolts holding the main latch striker on the vehicle body, adjust its position, and retighten.
Buying a Used Rivian R1S Trunk Lid Hinge
Purchasing a used OEM hinge is a cost-effective way to resolve issues from collision damage. Since these hinges are primarily robust metal, a used part from a low-mileage vehicle is often just as good as a new one.
Physical Inspection Checklist
- Check for Bends or Cracks: Carefully inspect the entire hinge for any signs of bending, twisting, or stress cracks. A hinge that has been compromised in an accident will not hold the door in alignment.
- Inspect Mounting Points: Ensure the mounting holes are not elongated, stripped, or damaged. The hinge must mount flush and securely to both the body and the door panel.
- Look for Corrosion: Check for any significant rust or corrosion, especially around welds and mounting surfaces. While surface rust is often cosmetic, deep corrosion can weaken the hinge.
- Confirm Upper vs. Lower: Double-check whether you are buying an upper liftgate hinge or a lower tailgate hinge. They have completely different designs. Ask the seller to confirm which part of the split door it came from.
Replacement Overview
Installation Difficulty
- Lower Tailgate Hinges: 2/5 (Moderate). Replacement is relatively straightforward. It involves supporting the tailgate, removing trim panels inside the cargo area to access the bolts, unbolting the old hinges, and installing the new ones. Alignment will be required after installation.
- Upper Liftgate Hinges: 4/5 (Difficult). This is a more complex job best left to experienced technicians or a body shop. The heavy upper liftgate must be securely supported. It involves removing significant interior trim, disconnecting the power lift struts, and carefully managing wiring. Improper removal can lead to injury or damage to the vehicle. Post-installation electronic calibration of the power liftgate system may be required.

Frequently Asked Questions (FAQ)
My R1S liftgate makes a popping noise. Do I need new hinges?
Not necessarily. A popping noise is a common issue, often caused by the liftgate panel touching the roof applique or the weather seal rubbing. Try cleaning and lubricating the main weather seal first. If the noise persists, it may be an alignment issue that can be adjusted at a service center, sometimes under the provisions of TSB RSB-56-23-002-1 for eligible vehicles.
Can I replace just one hinge?
While it is physically possible, it is highly recommended to replace hinges in pairs. Hinges wear at a similar rate, and replacing only one can put uneven stress on the new part and the old one, making alignment difficult and potentially causing premature failure of the remaining old hinge.
What is the difference between the upper and lower hinges?
The upper hinges support the large, powered liftgate and are designed to work with electric struts. The lower hinges support the smaller, manual tailgate that folds down. They have completely different shapes, sizes, and mounting points and are not interchangeable.
Is hinge replacement covered under the Rivian warranty?
If the hinge has failed due to a manufacturing defect and the vehicle is within the warranty period, the replacement should be covered. Issues like misalignment from the factory or problems covered by a TSB are also typically handled under warranty. However, damage from an accident or misuse would not be covered.
