2018-2019 INFINITI Q70 Dash Panel: Color Matching, Rattles, and Replacement

Symptoms of a Failing Dash Panel

Unlike mechanical parts, a dash panel typically fails through physical degradation or by causing secondary issues with the components it houses. Here’s what to look for:

Physical Damage and Deterioration

While the widespread "sticky dash" or "melting dash" issue that plagued earlier Infiniti models is not a common problem for the 2018-2019 Q70, some material degradation can still occur. Look for signs of warping, especially near the defroster vents at the base of the windshield where sun exposure is most intense. You might also see cracking, peeling, or discoloration of the vinyl or leather surfaces over time. High heat and sun exposure are the primary causes of this type of damage.

Persistent Rattles and Squeaks

Annoying rattles from the dashboard area are a frequent complaint among vehicle owners. These sounds can be caused by broken mounting tabs, loose internal clips, or components that have come unsecured behind the panel. While a rattle itself isn't a critical failure, it can be very difficult to pinpoint and may require significant disassembly to fix.

Airbag Warning Light (SRS Light)

The passenger-side airbag is integrated into the dash panel assembly. If the airbag warning light (SRS light) illuminates on your instrument cluster, it could indicate a problem with the airbag module itself or, more commonly, a fault in its wiring connector. A TSB for other Infiniti models highlights the sensitivity of the Occupant Classification System (OCS), which can be affected by electrical issues. An active SRS light means the airbag system may not deploy correctly in an accident, making this a critical safety issue that needs immediate diagnosis.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

For the 2018-2019 INFINITI Q70, there are no specific recalls for the dash panel itself. However, there are related recalls and TSBs that involve components housed within the dash.

• NHTSA Recall 19V654000: This recall addresses an issue where the back-up camera display settings can be adjusted so the rear view image is no longer visible. This is a software issue with the infotainment unit located in the dash, not a fault of the dash panel itself. The fix involves a software update from an Infiniti dealer.
• Infiniti TSB ITB18-040a: This technical service bulletin was released to address several infotainment issues on the 2018 Q70, including a blank reverse camera screen, a flickering display, and other software glitches. The solution is a software update for the Display Control Unit (DCU).
• Infiniti TSB ITB19-034a: For 2019 Q70 models with the VK56VD engine, this TSB addresses a no-start condition due to low battery voltage, which requires an ECM reprogram. While not a dash issue, electrical problems can sometimes manifest as dash-related symptoms.

Buying a Used 2018-2019 Q70 Dash Panel: A Buyer's Guide

Purchasing a used OEM dash panel can save you thousands of dollars compared to a new part. However, careful inspection is essential to ensure you get a quality, compatible component.

1. Verify Color and Trim Compatibility

This is the most critical step. The 2018-2019 Q70 was available with several interior color schemes, including Graphite (G), Wheat, Stone, and Java. The color code is typically found on the vehicle identification sticker in the driver's side door jamb. You must match this code exactly. Also, be aware of trim differences; Sport Package models may have unique stitching or materials.

2. Thoroughly Inspect for Physical Damage

Before purchasing, examine the entire dash panel for:

• Cracks and Warping: Pay close attention to the areas around the defroster vents and speaker grilles, which are prone to heat stress.
• Intact Mounting Points: Flip the dash over and inspect every single mounting tab, screw hole, and clip receiver. Broken tabs are a major cause of future rattles and are often non-repairable.
• Surface Condition: Look for deep scratches, scuffs, or signs of chemical damage from harsh cleaners. Check for any lingering stickiness, even though it's less common on these model years.
• Wiring Harnesses: Ensure any included wiring is intact, with no cut wires or damaged connectors. A compromised harness can create countless electrical problems.

3. Understand Airbag Policies

Most recycled dash panels are sold without the passenger airbag module. This is the standard and safest practice. The airbag from your vehicle is calibrated and registered to its VIN. Swapping it requires specialized knowledge and should only be performed by a professional technician who can ensure the system is re-installed and functioning correctly.

Replacement Cost and Difficulty

Replacing the dash panel on a 2018-2019 INFINITI Q70 is a highly complex and labor-intensive job.

• Installation Difficulty: 5 out of 5 (Professional Recommended)
• Estimated Time: 8-12 hours

This is not a DIY-friendly task. The procedure involves disconnecting the battery, deactivating and removing the airbag systems, removing the steering wheel and column, center console, A-pillar trim, instrument cluster, glove box, and all associated electronics and controls. Reassembly is equally complex, with a high risk of causing electronic faults or rattles if not done perfectly.
