BMW vs. Infiniti Reliability: Which is better?

It's a difficult task to compare the reliability of BMW and Infiniti. This is because both brands have areas where they outperform each other. For instance, while BMW has higher safety ratings, Infiniti beats it with cheaper repair and maintenance costs. This includes longer warranty periods on the Infini brand.

Let's look at the reliability ratings for both brands. According to RepairPal, BMW has a Reliability rating of 2.5/5.0, ranking 30th out of 32 car brands. Infiniti performs better with a reliability rating of 3.5/5.0, ranking 16th out of 32 car brands.

While Infiniti ranks higher than BMW on RepairPal, BMW does better on JD Power's dependability survey. The BMW brand ranks 3rd on the 2022 consumer reports reliability survey. However, there isn't any rating for Infiniti due to insufficient data or the low model count.

One of the first factors that differentiate the reliability of BMW and Infiniti is their engineering and design philosophies. BMW has always been interested in building cars that can race you through the ends of the world.

On the other hand, Infiniti, a Nissan luxury brand, struggled in the past to find its place in the market, regularly improving to maintain a reputation for producing high-quality vehicles. This is not without mentioning that they've struggled with reliability issues in the past.

One of the notable things about the Infiniti vs. BMW reliability comparison is that cost of ownership is high. BMWs have sporty, powerful engines, great acceleration, and handling, but you can also get this from Infiniti at a lesser price.

Gas mileage and engine performance are relative on both brands depending on the model that you choose. However, on an overall scale, you are getting superior performance from BMW. This comes at a more expensive purchase price.

There's no denying that you will get impressive designs from Infiniti's bigger models, like the QX60 and QX80, but this is not compared to what BMW offers on an overall scale. BMW's impressive interiors are justifiable because you are paying extra to get more.

BMW's design borders around building vehicles that create an impact while taking into consideration the need for dynamism. Infiniti's design philosophy emphasizes the need to produce dating, human-centered and progressive design.

The design reliability of BMW and Infiniti is like comparing the engineering prowess of the Germans and the Japanese.

However, BMW's engineering stands out for the effort it puts into designing and manufacturing its cars, using high-quality materials and advanced technology to create vehicles that are durable and long-lasting. This contributes to the higher resale value of BMW cars.

Infiniti vehicles are not entirely bad. They are made of high standards and superb designs. Both brands' headroom, legroom, cargo space, and passenger space depend on the model you choose.
