Luxury German sedans from BMW, Mercedes-Benz, Audi, and Porsche are among the most popular premium vehicles in Dubai and across the UAE.
They deliver exceptional performance, advanced safety systems, and refined comfort. However, recent reliability data and real-world workshop trends show that these vehicles require specialized maintenance—especially in the UAE’s extreme climate.

Recent Reliability Data from Trusted Sources
According to the J.D. Power 2025 U.S. Vehicle Dependability Study (VDS), which measures problems per 100 vehicles (PP100) after three years of ownership:
| Brand | Problems Per 100 Vehicles (PP100) |
|---|---|
| BMW | 189 |
| Mercedes-Benz | 243 |
| Audi | 273 |
| Industry Average | 202 |
Luxury vehicles typically report more issues due to higher technological complexity.
Additionally, Consumer Reports Annual Auto Reliability Surveys consistently show that European luxury brands experience more electrical and software-related issues than simpler platforms.
This trend is not a sign of poor engineering—but rather reflects the complexity of modern German automotive systems.
