Rivian Works to Fix Suspension and Assembly Problems in Its Electric Trucks and SUVs

Rivian Automotive is addressing manufacturing and assembly defects found in thousands of its R1T pickup trucks and R1S SUVs from 2022 through 2024. The problems range from issues with the hydraulic suspension system to wheel fasteners that were tightened to the wrong specifications—the kind of quality control stumbles that car startups often encounter as they scale production from hundreds to thousands of vehicles per month.

The company has filed technical reports with the National Highway Traffic Safety Administration (NHTSA) documenting several distinct problems. The most recent campaign involves 2023–2024 R1T and R1S models where wheel attachments may have been assembled with incorrect torque values. This is a procedural problem—the fasteners themselves are fine, but they were tightened to the wrong tightness—rather than a design flaw in the hardware itself.

Suspension System Issues

Rivian uses an air suspension system—basically a computer-controlled cushion of pressurized air instead of traditional steel springs—which allows the ride height to adjust automatically and helps with off-road capability. The company has identified issues with the hydraulic components that control this system in certain 2022 R1T vehicles. These systems involve pumps, fluid lines, and electronic controls, all of which must work reliably across different temperatures and road conditions.

In some cases, owners have reported an audible chirping noise when the vehicle articulates over bumps at low speeds (below 25 mph). This appears to be a noise and vibration issue rather than a safety hazard, but it reflects how tricky it is to tune a complex air suspension system that needs to handle both smooth highway driving and rough terrain.

A Recall and Broader Industry Context

Beyond these repair campaigns, Rivian recalled 19,641 R1T and R1S vehicles that had been serviced incorrectly. The problem: rear toe links—suspension parts that affect steering and stability—were assembled wrong. This is particularly concerning because these components directly influence how the vehicle handles.

This pattern is not unique to Rivian. Ford recently recalled over 412,000 Explorer SUVs for similar rear suspension toe link problems that could fracture and affect vehicle control. We saw comparable manufacturing quality challenges during the early production ramp of the Tesla Model S, when the company struggled to keep assembly precision consistent while scaling up delivery targets. The main difference now is that regulators require faster response times and more detailed documentation when issues surface.

The broader context here is that manufacturing at scale is genuinely hard, especially when you are a young company trying to hit ambitious delivery targets while also establishing new assembly processes from scratch. Suspension components are safety-critical, and even small mistakes matter.

The Wheel Fastener Problem

The wheel hub torque specification issue reveals how easy it is to go wrong even on something as straightforward as tightening bolts. Proper torque—the amount of twisting force applied—is fundamental to keeping wheels attached safely. The fact that newer fasteners were installed with incorrect tightness suggests gaps in training, quality checks, or communication between the engineering and production teams.

This particular defect apparently happened during service operations rather than during initial assembly at the factory, which points to possible gaps in how the service network is trained and supervised. Incorrectly torqued wheel attachments can lead to wheel separation or handling problems under hard braking or tight cornering.

What This Means for Rivian

For an electric vehicle company in its growth phase, these issues illustrate the complexity of scaling manufacturing. Rivian's vehicles use a software-defined architecture—meaning many functions are controlled by computers and can be updated remotely—which gives the company flexibility but also adds layers of complexity that must be validated during assembly.

The company can fix some problems remotely via software updates, but defects in physical assembly still require traditional recalls and trips to service centers. This mix of digital systems and mechanical assembly is becoming standard across the auto industry, but managing both simultaneously is a balancing act, especially for newer manufacturers still learning the rhythms of high-volume production.

From a manufacturing perspective, these campaigns are typical growing pains for any automaker scaling from small production numbers to volume manufacturing. Rivian's willingness to formally document and address these issues through official NHTSA channels shows the company is following established safety protocols. While these repairs carry near-term costs and logistical complexity for Rivian, they also provide the kind of real-world production feedback that helps manufacturers refine their processes and improve quality over time as they mature.
