Are you thinking of adding a Mercedes A-Class to your garage?
You may have already done some research on it, but as with any used car purchase, there’s a risk of buying someone else’s headache in automotive form.
So what years should be avoided when shopping for a Mercedes A-Class?
This article outlines what years are best avoided when buying a Mercedes A-Class and which ones should be considered seriously. Read on for a complete overview!
Overview: Mercedes A-Class years to avoid or to buy
Looking for a quick answer to your question? Here is an overview of the Mercedes A-Class years to avoid or to buy.
Here are the Mercedes A-Class years to avoid:
| Year | Generation | Main Complaints |
|---|---|---|
| 2012 | W176 | – Uses Renault engines – Failed timing chains – Turbocharger failure |
| 2004 | W169 | – Failed CVT transmission – Overheating engine – Fuel pump failure |
| 1997 | W168 | – Failed the ‘Moose’ test |
When looking for the best Mercedes A-Class years to buy, look for any model from 2018 onwards. This generation of Mercedes A-Class has surprisingly few issues and seems to do well on reliability overall.
Which Mercedes A-Class years should you avoid?
Despite the fact that the Mercedes A-Class is a great all-around car, there are specific production years that have a higher likelihood of experiencing issues.
Let’s check out three Mercedes A-Class model years that received the highest number of complaints:
2012 Mercedes A-Class
First of all, it’s recommended to avoid the 2012 Mercedes A-Class.
This model year introduced the third generation of the A-Class, the W176. And it came with a significant change in its engine.
You see, some of the 2012 Mercedes A-Class models, including the A160 d and A180 d, were equipped with Renault engines.
While Renault makes some pretty decent engines, they might not be what you’d expect in a Mercedes.
Why does this matter?
Well, the combination of a Mercedes design with a Renault engine led to mixed reviews. Some people didn’t mind, but others had some reliability concerns, particularly about possible premature timing chain failures.
Note: The 2012 model year wasn’t the only one where the A-Class was equipped with Renault engines. For a full overview, check out our article here!
Lastly, if you’re looking at an A45 AMG from 2012, note that one common issue is a turbocharger failure. This issue is caused by the oil hose that leads to the turbocharger, which gets contaminated over time and blocks the oil flow. No oil, no bueno!
2004 Mercedes A-Class
The next year to avoid is the 2004 Mercedes A-Class, which started the W169 generation.
Whenever car makers introduce a new generation, it’s a bit like taking a daring leap. While the enthusiasm and innovation are evident, sometimes, the landing isn’t as smooth as one would hope.
One of the main issues was with the CVT (Continuously Variable Transmission). A bunch of owners reported failing CVT transmissions.
And guess what the culprit was? The ECU, or Electronic Control Unit. It’s like the car’s brain, and when there’s an internal component breakdown in the ECU, well, it can lead to some pretty frustrating gearbox issues.
Other 2004 A-Class models had a tendency to overheat their engines. Not only is it inconvenient, but it also poses a potential risk if not attended to promptly.
And lastly, there’s the fuel pump.
Unfortunately, for some 2004 A-Class owners, the fuel pump stopped working, leading to poor car performance or, worse, a complete shutdown.

1997 Mercedes A-Class
Let’s rewind a bit further and go to the late 90s: 1997, to be precise.
The last Mercedes A-Class year that’s better to be avoided is 1997.
Remember the legendary “Moose Test”?
No, it’s not about spotting moose in the wild; it’s a challenging maneuverability test performed on cars to see how they’d handle sudden obstacles – like, say, a moose suddenly crossing your path.
Well, the 1997 A-Class famously failed it.
The result? A bit of a PR hiccup for Mercedes, as the car unexpectedly tipped over during the test:
The failure of the Moose Test raised eyebrows. It made buyers wonder: Is the A-Class safe?
Mercedes quickly addressed the issue and made significant adjustments to ensure stability in subsequent models.
They not only fixed the A-Class’s issues but also introduced the Electronic Stability Program (ESP) as standard, a feature that later became a norm in many cars across the globe.
So, if you’re ever considering purchasing a 1997 Mercedes A-Class, just be aware of its early-days quirks and the improvements made post-’97.

Which Mercedes A-Class engine is best?
Engines are to cars what hearts are to us – vital, powerful, and, when performing at their best, capable of extraordinary feats.
Mercedes, with its rich history in engine innovation, has presented many powerhouses over the years.
