Why are mechanics losing trust in OEM Auto Part Manufacturers
Valerie Raskovic
For years, original equipment manufacturer (OEM) parts were considered the gold standard. They were preferred by mechanics and DIYers for one specific reason above all and that is because they were built to exact specifications, thoroughly tested, and generally more reliable than aftermarket alternatives. However, in recent years, a combination of global manufacturing shifts, major cost-cutting measures, and changing supplier practices has contributed to a noticeable decline in confidence. As a result, a growing number of technicians, enthusiasts, and everyday drivers have begun to question whether OEM parts still live up to that reputation and are worth paying a considerable price premium over aftermarket parts.
The Shift in Product
The shift is a real thing that is happening across many different industries as manufacturers try to curb inflation while delivering profits. They find that outsourcing manufacturing to countries with cheaper labor and more business-friendly laws tends to be more profitable. While outsourcing production of car parts in low-cost areas is nothing new, in fact, the aftermarket auto parts industry strives specifically for that reason, as they are able to make parts cheaper and offer them at a lower cost. However, historically many OEM components were produced in countries like Germany and the United States, where strict quality control standards and experienced labor played a major role in consistency.
Needless to say, while shifting production to lower-cost regions and outsourcing to new suppliers across the global markets has generated OEM companies more profits, it has also taken its toll on the consumer confidence in OEM products. At the end of the day, the reason why people pay more for OEM parts is because they are often perceived to have overall better quality and superior manufacturing standards. If you take those benefits out of the equation, then the incentive to buy OEM can diminish significantly.
Just to clear the air, it is important to understand that globalization itself isn’t inherently negative. Most issues arise due to lack of proper oversight and enforcement, often leading to inconsistencies in materials, tolerances, and overall quality. This is accentuated when OEM companies rush to cut cost by bringing in new suppliers too quickly or without sufficient oversight.
It’s important to note that not all OEM parts have taken this road of prioritizing profits over quality. Some manufacturers still maintain strict standards and produce highly reliable components. However, the key difference today is inconsistency. Where OEM quality was once predictable, it can now vary depending on production location, supplier and part(s) themselves.
Cost Cutting Isn’t Just an Aftermarket Problem
There’s a common belief that only aftermarket parts suffer from quality issues, while OEM parts remain untouched. However, that line has become increasingly blurred.
We have already seen modern cost-reduction strategies affect OEM parts in several ways:
- Use of inferior lower-cost materials
- Simplified component designs
- Reduced redundancy in critical systems
- Shortened testing cycles
- Reduced tolerance thresholds
The decision of hastily moving production and cutting costs by supplementing materials with cheaper alternatives with less oversight may help manufacturers meet pricing targets, but they can also lead to shorter part lifespans and increased defects and failure rates.
Supplier Changes and Rebranding Confusion
Another factor impacting trust is the complexity of modern supply chains. Many OEM parts are not actually made by the automaker itself but by third-party suppliers. Quality issues can arise when suppliers are sometimes switched mid-production. While most consumers assume finding a part with the same OEM part number imprinted on the part means it will have consistent performance and quality, that is not always true. Often times a part with the same part number may come from a completely different manufacturer from a completely different part of the globe.
To add fuel to the fire, manufacturers may redesign the part without ever updating the part number. While the part may still perform the same function, they can be significantly different from their earlier versions. Needless to say, this can create confusion, especially when a replacement part doesn’t perform like the original that came with the vehicle or one that was replaced years prior.
Real-World Impact
For vehicle owners and repair professionals, these changes show up in several frustrating ways. We have seen more instances of parts failing prematurely or even worse, coming out defective out of the box. Complaints of inconsistent fitment or performance of OEM parts are also on the rise, causing a drastic increase in warranty claims and repeat repairs. While this issue presents a number of hurdles for auto repair shops and dealerships, the brunt of the cost is absorbed by the consumer primarily in higher overall ownership costs.
Awareness is Growing Among Consumers
Consumers are starting to realize that using OEM replacement parts may no longer guarantee the same longevity they once had. More owners are sharing their experiences online and technicians continue to report patterns in failures, bringing awareness to this growing problem.
Buyers are starting to:
- Compare OEM to high-quality aftermarket parts more closely
- Research supplier brands behind OEM components
- Pay closer attention to where parts are manufactured
This shift reflects a broader realization that a brand name alone is no longer a guarantee of quality.
The Takeaway
OEM parts still play a critical role in vehicle maintenance and repair, but the landscape has changed. This is why it is vital to research parts, understand their origin and research the reputation of the manufacturer. Working with knowledgeable professionals can also help ensure you’re getting the quality your vehicle deserves.
