# Steering Concerns Continue in E85/E86 BMW Z4 Models: BMW Has Not Initiated a Recall Despite Longstanding Safety Worries
### Introduction
The BMW Z4, especially the E85 (roadster) and E86 (coupe) versions manufactured from 2002 to 2008, has been renowned for its elegant aesthetics, dynamic handling, and enjoyable driving experience. However, for nearly twenty years, owners of these vehicles have reported ongoing steering troubles that could greatly impact the safety and operability of the car. In spite of numerous complaints and rising alarm within the automotive community, BMW has not yet launched a formal recall to remedy these issues. This article examines the nature of the steering dilemmas, the feedback from Z4 owners, and why BMW has refrained from taking significant action.
### The Steering Issue: A Recurring Concern
One of the most commonly reported steering issues in the E85/E86 BMW Z4 models is a condition referred to as “sticky steering.” This issue is especially prominent during warm weather, where the steering wheel becomes rigid and challenging to maneuver, particularly at lower speeds. Drivers have described feeling as though the steering wheel is “sticking,” necessitating extra force to make adjustments. This can lead to a notable decrease in steering accuracy, complicating the task of keeping control of the vehicle, especially in sharp turns or during emergency situations.
Beyond sticky steering, some owners have mentioned experiencing a “dead zone” in the steering, where the wheel feels numb or loose near the center. This could result in delayed responses while executing minor steering adjustments, further undermining the vehicle’s handling and safety.
### The Underlying Cause: Electric Power Steering (EPS) System
The steering problems in the E85/E86 Z4 models are primarily linked to the Electric Power Steering (EPS) system. Unlike traditional hydraulic power steering setups that utilize fluid pressure for assistance, the EPS system depends on an electric motor to facilitate steering. While EPS systems have benefits like enhanced fuel efficiency and lower maintenance needs, they can suffer from temperature-related issues, particularly as components expand or contract in response to heat.
In the case of the Z4, it’s believed that components of the EPS system’s motor or steering column may be impacted by thermal expansion, resulting in steering that becomes stiff or unresponsive during hot weather. Some owners have reported that the problem seems to lessen in cooler conditions, strengthening the hypothesis that heat significantly contributes to the issue.
### Owner Experiences: Increasing Discontent
Over the years, many Z4 owners have turned to online forums, social media, and consumer complaint platforms to recount their experiences with steering problems. Numerous individuals have conveyed frustration not just with the issue itself, but also with BMW’s unresponsiveness. Some have indicated spending thousands on repairs, including the replacement of the entire steering column or EPS motor, only to discover that the issue persists or recurs shortly thereafter.
One Z4 owner recounted their experience on a well-known BMW forum, stating, “I’ve had my steering column swapped out twice, and the issue still resurfaces every summer. It’s disheartening because I adore the car, but I don’t feel secure driving it when the steering misbehaves.”
Another owner expressed similar frustrations, saying, “The sticky steering feels like I’m battling the vehicle to stay on track. It’s particularly nerve-wracking on twisting roads or in congested traffic.”
### BMW’s Response: No Recall, Limited Recognition
In spite of the extensive nature of the steering troubles, BMW has not initiated an official recall for the E85/E86 Z4 models. The manufacturer has acknowledged the issue in certain cases, providing technical service bulletins (TSBs) to dealerships detailing potential solutions, such as recalibrating the EPS system or replacing specific components. However, these remedies have not proven universally effective, and many owners have noted that the problem continues even after adhering to BMW’s suggested repairs.
One possible reason BMW may be reluctant to implement a recall is the challenge in replicating the issue under controlled circumstances. The steering troubles are frequently sporadic and tend to manifest mainly in warm weather, complicating the diagnosis process for technicians during standard service appointments. Furthermore, BMW may argue that the problem doesn’t represent an immediate safety threat, as the steering doesn’t completely fail but instead becomes more difficult to maneuver.
Nevertheless, many Z4 owners and automotive safety advocates dispute this evaluation, contending that any issue jeopardizing steering control should be regarded as a serious safety matter. In critical situations, even a minor delay in steering response could result in dire outcomes.
### Why No Recall?
There are various potential explanations for BMW’s failure to issue a recall for the E85/E86 Z4 models, despite the persistent steering problems:
1. **Expense**: Implementing a recall can be a costly endeavor for car manufacturers, especially if the issue impacts a significant volume of vehicles. Replacing or fixing EPS systems across all
