Mercedes vs Audi vs BMW Reliability
Luxury vehicles are known for their premium performance and quality. With the newest and best features on the market, luxury models go above and beyond in every way imaginable. This is especially true for highly sought after luxury brands like Mercedes-Benz, Audi, and BMW.
When it comes to overall reliability, though, which one can you count on most? In this comparison, we at BMW of Stratham will show you how Mercedes-Benz vs. Audi vs. BMW stack up when it comes to reliability.
Luxury car drivers near Stratham, Portsmouth, and Exeter, NH, can read on to see which brand is the most dependable! Contact us with any questions!
BMW vs Audi vs Mercedes-Benz: Dependability
When deciding among these three German-engineered luxury brands, it’s important to choose a model you know will be by your side for years to come. One way to determine the longevity of a brand is by studying their dependability scores through J.D. Power.
J.D. Power was founded more 50 years ago with the purpose of giving a voice to consumers. In doing so, they hope to increase brand awareness to help individuals like you make the best car-buying decision.
One of the ways they provide this information is through their annual U.S. Vehicle Dependability Study™. This study ranks vehicles based on the number of problems reported per 100 cars. The lower the score, the better dependability for that model.
J.D. Power 2021 U.S. Vehicle Dependability Study™:
- BMW: 108 per 100 vehicles
- Mercedes-Benz: 122 per 100 vehicles
- Audi: 127 per 100 vehicles
As you can see, BMW scores much better than either Mercedes-Benz or Audi. Furthermore, it ranks far better than the industry average of 121 problems per 100 vehicles.
While Mercedes is close to the industry average, Mercedes-Benz and Audi both rank lower than the average number of problems per 100 vehicles.
BMW vs Audi vs Mercedes: Warranty
Another way to determine which brand will be by your side longer is to study the warranties offered by each brand. Warranties provide peace of mind, knowing you have the help of the manufacturer if the unexpected occurs.
Luckily for you, no matter which luxury brand you choose, your BMW, Audi, or Mercedes-Benz comes with warranty options you’re sure to love.

Mercedes-Benz |
|
4-year/50,000-mile Limited Warranty |
|
|

|
12-year Anti-Corrosion Warranty |

While each brand offers the same New Vehicle Limited Warranty, only BMW and Audi offer the extra protection of the Anti-Corrosion Warranty.
Extra Reliability With the Maintenance Plans
In addition to the warranty coverage offered by BMW, Audi, and Mercedes-Benz, you can reap the benefits of extra reliability thanks to the maintenance plans offered by these brands. Let’s take a closer look!
BMW Maintenance Plan
To provide you with peace of mind, BMW models come standard with BMW Ultimate Care—their complimentary maintenance package—for three years or 36,000 miles, whichever comes first. Some of the features of BMW Ultimate Care include:
- Engine oil and filter changes
- Cabin and engine air filter changes
- Brake fluid check
- Spark plug replacement
- And more
Thanks to this plan, you can keep your BMW in tip-top shape for years to come and at no additional cost to you.
Audi Maintenance Plan
A maintenance plan is offered by Audi to help keep your vehicle happy and healthy, too. Services like engine oil and filter changes, wiper blade replacements, brake service, and more are included with Audi Care.
However, unlike BMW Ultimate Care, Audi Care is not a complimentary service. Rather, this is a pre-paid service you must opt into.
Mercedes-Benz Maintenance Plan
Likewise, Mercedes-Benz also offers a maintenance plan so your vehicle can receive required maintenance for less than expected. The maintenance plan offered by Mercedes-Benz covers routine service every year or 10,000 miles, whichever comes first.
However, to get these benefits, you must purchase a pre-paid maintenance plan annually.
BMW vs Audi vs Mercedes: Safety Features
Finally, another way to choose the brand that’s most reliable is by comparing the safety features of the BMW vs. Audi vs. Mercedes-Benz. Here, we’ll take a look at their active safety features—those that help prevent a collision—offered with each brand.
Collision Monitoring Features
Vehicle reliability means being able to depend on your car to help keep you and your loved ones safe. All three brands come with a variety of cameras and sensors that monitor a range around your vehicle. These technologies check for potential hazards—such as other vehicles and pedestrians—and alert you when one is detected.
That way, you can make any necessary adjustments to prevent a collision.
Each brand offers a variety of these driver assist features to help provide complete protection. Let’s take a look at the standard safety features offered by a core model SUV from each brand—2021 BMW X5, 2021 Audi Q5, and 2021 Mercedes-Benz GLE—to help you get a better idea of these standard features.

While each brand offers a variety of standard features to help keep you safe, BMW may be the best option in terms of safety since it comes standard with all four of these features. The Audi Q5, on the other hand, only comes standard with three of them while the Mercedes GLE only comes standard with two.
Pre-Collision Safety
While each model offers a variety of active safety features that work hard to help prevent a collision, the unexpected may still occur. Luckily, BMW, Audi, and Mercedes-Benz have a second safety suite that works to help reduce the severity in the event an unavoidable collision is detected.
With BMW, several of its models come standard with the Active Protection System. This system detects an unavoidable collision and can perform these automatic features:
- Pretension safety belts
- Close windows and moonroof
- Activate post-crash braking
A similar system is offered by Audi as Audi pre sense® basic and by Mercedes-Benz as PRE-SAFE®.
Another safety feature of BMW is the Battery Safety Terminal, a system that automatically disconnects the alternator, fuel pump, and battery after a collision. This system will also unlock the doors and turn on the hazard lights.
Other than the automatic enabling of hazard lights with Audi vehicles, the rest of these features won’t be found on either of the other two luxury brands.

Had a great experience at BMW of Stratham. They completed multiple service requests while I waited, and I was on my way by lunchtime.

I had an excellent experience with the dealership. My prior BMW x5 was purchased new less than a year ago and was totaled by a reckless driver hitting me. The thought of buying another car was pretty stressful, but I knew to reach out to Scot Murby since I had just worked with him less than a year ago.
I had a few things that were really important to me—the color, the driver-assist features, and the tow hitch—and I didn’t have the time to build something custom. Scot searched the country and was able to find a ... Read More DealerRater - Apr 27, 2026

I had a very positive experience at BMW of Stratham. I stopped by near the end of the day to pick up brake parts I had ordered online, and while I was there, I checked in with the service department to get a quote for installing rear brake pads and rotors.
Even though Adam Webster was about to leave for the day, he still took the time to help me. He let me know about a brake special they were running, which ended up saving me money. Since my brake light was on, I was hoping to get the work ... Read More DealerRater - Apr 14, 2026
