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.

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.
Mercedes-Benz vs Audi vs BMW: Which One Is Best for You?
Looking to see whether Mercedes-Benz vs. Audi vs. BMW is the best choice based on reliability? As you can see in our comparison, BMW goes above and beyond to provide reliable vehicles you can count on in all kinds of situations. Get behind the wheel of a BMW today and see for yourself just how dependable it’s designed to be.

I plan on doing business here again, and hope anyone reading this will consider taking their business here.

Scheduled the appointment for 9:45 for an oil change. They said it would take 2 hrs. I called about 4 hrs after dropping it off and the car wasn't completed yet. Picked it up end of day and asked for it to be washed. That wasn't completed. The service advisor had already left and didn't refer me over to anyone so didn't know who to get my keys from. Giving a good rating so it doesn't hurt the score but the service dept needs a lot of work.
