# Ongoing Steering Challenges in E85/E86 BMW Z4: Two Decades Without a Recall in Light of Significant Safety Issues
## Introduction
The BMW Z4, especially the E85 (roadster) and E86 (coupe) variants produced from 2002 to 2008, has been admired for its elegant styling, athletic handling, and enjoyable driving experience. However, beneath the allure of this legendary roadster exists a lingering problem that has bothered owners for almost twenty years: steering difficulties that can drastically impact safety. In spite of numerous grievances and widespread recognition of the problem, BMW has not implemented a formal recall, leaving many Z4 owners feeling frustrated and anxious.
## The Steering Issue: What’s Occurring?
The steering complications in the E85/E86 BMW Z4 generally present in two primary forms:
1. **Sticky Steering**: This is the most frequently reported issue. Drivers notice a distinct “stickiness” or resistance when attempting to steer, particularly at highway speeds. The steering wheel may seem to get lodged in a fixed position, necessitating additional effort to make adjustments. This can be particularly perilous when making minor corrections at higher speeds, as the driver might overcorrect, resulting in erratic movements.
2. **Excessively Sensitive Steering**: In certain instances, drivers report that the steering becomes excessively sensitive, making it challenging to retain control, especially on uneven or twisting roads. This can create a feeling of unpredictability and danger, particularly in demanding driving conditions.
Both issues tend to worsen with temperature fluctuations, with many owners claiming that the problems intensify in warm weather.
## Underlying Cause: Electric Power Steering (EPS) System
The BMW Z4 E85/E86 models come equipped with an Electric Power Steering (EPS) system, a technology that was quite innovative at the time the car was produced. In contrast to conventional hydraulic power steering systems, EPS utilizes an electric motor to aid in steering, which reduces weight and enhances fuel efficiency. Nonetheless, this system has demonstrated to be problematic in the Z4.
The main culprit for the steering issues seems to be the EPS motor and the steering column. Over time, the internal components of the EPS system can degrade or misalign, resulting in the “sticky” or overly sensitive steering characteristics. Furthermore, the system appears to be especially responsive to temperature changes, with many owners noting that steering issues become more apparent during hot weather, likely due to thermal expansion impacting the parts.
## An Extended History of Complaints
Since the early 2000s, BMW Z4 owners have been reporting steering difficulties to both BMW and regulatory institutions such as the National Highway Traffic Safety Administration (NHTSA) in the United States. Online forums are brimming with discussions surrounding the problem, with numerous owners sharing their experiences and frustrations.
Despite the widespread nature of the issue, BMW has consistently minimized the seriousness of the concern. While the company has acknowledged that some Z4s may contend with steering challenges, they have often attributed it to “normal wear and tear” or environmental influences, rather than a design flaw. This stance has left many owners feeling neglected, as they often find themselves bearing the costs for expensive repairs, which can range from replacing the entire steering column to less significant adjustments.
## Why Has There Been No Recall?
Considering the safety ramifications of the steering problems, many Z4 owners have questioned the absence of a recall from BMW. The rationale likely stems from a blend of factors:
1. **Expense**: Launching a recall for such a widespread issue would be financially burdensome for BMW, particularly since the problem impacts a significant number of vehicles made over several years. Replacing or repairing the EPS system in every affected Z4 would demand considerable resources.
2. **Liability**: By initiating a recall, BMW would be admitting to a fundamental flaw in the design of the Z4’s steering system. This could expose the company to legal action and greater financial responsibility, especially if accidents or injuries have occurred due to the steering issues.
3. **Regulatory Inaction**: Although many complaints have been lodged with agencies like the NHTSA, no regulatory authority has compelled BMW to issue a recall. This may be due to the fact that, while the steering issues are concerning, they have not led to a significant number of reported accidents or fatalities. Without concrete evidence linking the steering problems to serious accidents, regulators may hesitate to act.
## The Effect on Owners
For Z4 owners, the lack of a recall has become a source of irritation and financial burden. Many have had to incur expensive repair costs out of their own funds, with some even choosing to sell their vehicles due to safety worries. This issue has also influenced the resale value of the Z4, as potential buyers often approach the purchase of a car with known steering complications with caution.
Moreover, the steering problems have tarnished the reputation of the Z4, a vehicle that was previously regarded as
