It’s a frustrating reality many of us in the auto repair business are facing: the declining quality of aftermarket car parts. It feels like just in the last year, the issues have become noticeably more frequent and more problematic. From online suppliers to even some local factors, the gamble of fitting a new part is becoming more of a lottery than a reliable fix. This isn’t just about saving money; it’s costing us time, reputation, and ultimately, customer satisfaction.
The Shocking Examples Pile Up
My own recent experiences are a testament to this growing trend. Take, for instance, a seemingly simple job like replacing camshaft oil seals. Ordering a set online, they arrived promptly and appeared to be the correct size. However, during installation, they felt… loose. Alarm bells rang, but trusting the size markings, I proceeded. Almost immediately after the engine was running, leaks sprung up from both seals. The fix? Genuine OEM parts. Suddenly, the slightly higher price tag made perfect sense after the wasted time and mess.
Then there was the cam cover gasket. Another seemingly straightforward replacement turned into a nightmare. The gasket itself was visibly distorted straight out of the packaging. Fitting it was a struggle, requiring sealant just to hold it in place, a practice I usually avoid. Unsurprisingly, it leaked right away. Upon closer inspection, the thickness was wildly inconsistent across the gasket. Again, an OEM replacement solved the problem instantly, highlighting the stark difference in manufacturing quality.

Even trusted brands aren’t immune, or at least, their names are being exploited. A Mahle oil filter arrived in packaging that looked suspiciously cheap – thin cardboard, poor print quality, and crucially, lacking the hologram I usually associate with genuine Mahle products. The suspicion of it being counterfeit was too strong, and it went straight into the bin. Is it worth the risk of engine damage to save a few dollars on a potentially fake filter?
Oxygen sensors are another area where cheap parts can cause headaches. Fitting an eBay-sourced sensor for a friend, the engine problems persisted. It was only after swapping it for a more expensive, branded sensor from a reputable local supplier that the issue was resolved. Yes, it was three times the price, but it worked, saving diagnostic time and further frustration.

Ignition coils on a Renault presented another lesson. Replacing all four coils didn’t fix the misfire and engine light. Hours were spent diagnosing the system, only to discover one of the new coils was faulty straight out of the box. This kind of failure with new components is becoming alarmingly common.
An air conditioning condenser looked like it had been painted with something resembling tar – the finish was that rough and uneven. It was immediately returned, and a week was spent waiting for a branded replacement. Time is money in this business, and these delays add up.
Even water pumps, critical engine components, are falling victim to poor quality. One fitted recently, supplied in a plain brown box with no branding, leaked after just a week. The pattern is clear: unbranded, cheap parts are often a false economy.
Brake Discs: A Stark Quality Contrast
The most recent and perhaps most shocking example involves brake discs. Ordering 25 Escort brake discs, the local factors sourced them from multiple suppliers to fulfill the bulk order. The variation in quality was astounding. Delphi discs had a flawless machined finish and were a dream to work with. Other known brands were comparable in quality. However, some discs were from brands I’d never encountered before, and the finish was appalling. Machining them was a nightmare; the metal was hard and produced dust rather than shavings. This inconsistency in even essential safety components like brake discs is deeply concerning.

The Cost of Cheap Parts
The lesson from all of this is clear: buying cheap, unbranded, or potentially counterfeit parts is a false economy. The time wasted diagnosing issues caused by faulty new parts, the cost of rework, and the potential damage to reputation far outweigh any initial savings. From now on, sticking to quality branded parts from reputable suppliers is the only sensible approach. And for customers asking for parts to be fitted, insisting on quality components is now a non-negotiable part of the service. As one factor wisely said, “people only look at the price,” but in the long run, quality and reliability are what truly matter in auto repair and Aic Car Parts selection.
