Understand the Regenerative Braking System

• Regenerative braking captures energy that would otherwise be lost during braking and stores it in the vehicle's battery. Inconsistencies could be due to driving conditions, brake pad wear, software issues, or thermal conditions.
• Ensuring a general understanding of how regenerative braking is supposed to work can help identify specific areas where inconsistencies are happening.

Check for Software Updates

• Rivian frequently releases software updates that enhance vehicle performance, including the braking system. Make sure the vehicle’s software is up to date to rectify any software-related issues.
• Check for updates via the vehicle’s user interface or consult the Rivian companion app and apply any available updates.

Evaluate Driving Habits and Conditions

• Driving habits like frequent hard braking or aggressive driving can impact the regenerative braking system’s consistency. Try to adopt smoother driving habits to evaluate if the inconsistency reduces.
• Consider the influence of driving conditions, like steep hills or extreme temperatures, as they can affect the performance of regenerative braking.

Inspect Brake Components

• Inspect the physical braking components, such as brake pads and rotors, for wear and tear that could affect the efficiency of the regenerative system.
• Regular maintenance checks with professional technicians can help identify mechanical issues that might not be obvious but affect braking performance.

Adjust Regenerative Braking Settings

• Rivian R1T allows drivers to adjust regenerative braking strength. Check the current setting and experiment with different levels to find a more consistent braking experience.
• Settings are typically accessible through the vehicle’s infotainment system.

Perform a System Reset

• Sometimes, resetting the vehicle’s systems can rectify glitches, including those affecting regenerative braking.
• Consult the vehicle’s manual or contact Rivian support for guidance on performing a proper system reset.

Consult Professional Help

• If inconsistencies persist, it is advisable to contact Rivian customer service or visit a certified service center to have the system professionally assessed.
• Technicians can conduct detailed diagnostics to identify and fix underlying issues with specialized equipment.

Document Observations

• Keep a log of when inconsistencies occur, under what conditions, and any error messages that may appear on the vehicle’s display. This information can be crucial when seeking professional assistance.
• Monitoring battery performance and energy usage trends can also provide insights into the system’s efficiency.
