8 most reliable luxury cars

All cars are built for the same generic purpose, but they can cost anywhere from a few thousand to a few million dollars. Cheap models usually fulfill basic needs, while expensive cars have advanced features, fine materials and powerful engines.

Expensive flagship and performance cars are usually meant for those who don't care about the maintenance and fuel costs. Often, the complexity of these cars also results in more frequent faults and visits to the mechanic. Luckily, some manufacturers focus on reliability even when making fancy cars.

We've made a list of the 8 most reliable luxury cars. To do so, we analyzed data from carVertical vehicle history reports, as well studies done by third-parties, like J.D. Power, What Car?, Consumer Reports, RepairPal, and more.

Poor reliability and high maintenance costs aren't the same thing

The car's reliability highly depends on its maintenance. All cars need regular oil and filter changes, brake system checks, and other checkups to prevent various issues. The more expensive the car, the more expensive the spare parts, often leading owners to think that the car is unreliable.

According to YourMechanic, the maintenance of a subcompact Toyota Yaris will cost you $3,289 over 10 years, while you’ll have to pay $14,600 for a Lincoln MKS – a large luxury sedan. The luxury vehicle's additional comfort and features result in higher maintenance costs.

Top 8 most reliable luxury cars

Public wisdom about car reliability is worth little without supporting facts – even the most dependable brands have made mistakes throughout the years. We picked these 8 longest-lasting luxury cars by comparing car owner survey data and checking accident history reports, which also have a huge impact on the car's safety and reliability.

8. Volvo S90

The current Volvo S90 was launched in 2016. While the early versions were prone to air conditioning, build quality, and software issues, the newer versions are among the most reliable sedans. Customers have reported minor infotainment system and electrical issues but other than that, the S90 serves great.

Long gone are the days of bulletproof, boxy Volvo cars, as now Volvo is owned by Chinese multinational automotive company Geely Holding Group. The S90 is the biggest sedan in Volvo's lineup and offers generous standard features, great legroom, and minimalistic Scandinavian interior design.

The current S90 is available with 10 powertrains, including 2 hybrid versions. Some versions are also available with AWD systems and over 300 hp engines, providing great performance.

7. Infiniti Q50

Infiniti is Nissan's luxury division, which means that Infiniti cars are built mostly from Nissan parts. The Q50 has been around for over a decade, and owners confidently confirm that it's a reliable luxury car. A brand new Q50 is currently available with a 3.0-liter twin-turbocharged Nissan engine, which isn't prone to any issues, but owners aren't happy about averaging 20 mpg. Older models came with more engine options, including a 2.2-liter diesel that averages 40 mpg.

Buyers often look for a used Q50 because of a lower price and a wider variety of engines. However, 54.97% of all Infiniti Q50 checked on carVertical have been in accidents in the past. A damaged car may be unsafe, prone to corrosion and various issues if not repaired properly after an accident, so it’s important to stay vigilant when buying a used vehicle.

Since the Q50 was launched in 2013, its design is a bit old-fashioned. However, if you’re looking for an affordable luxury sedan, this car is a safe choice.

6. Lexus ES

The Lexus ES was a rebadged Toyota Camry over a decade ago, but now it's a totally different car. The 2024 model got a Quality and Reliability score of 85 out of 100 from J.D. Power, which is considered great. Some owners reported GPS failures and small oil leaks, but these issues were fixed for free under warranty.

The ES is not as desirable as the German luxury rivals, but it may find its customer. Lexus has some of the best automotive hybrid systems on the market, and the ES costs less than the 5 Series, Audi A6, or E-Class. Moreover, the build quality is astonishing – premium interior materials, hand stitching, and pleasant ergonomics make it stand out from the crowd.

Lexus has never put a diesel engine in any of the ES models, resulting in poor sales in Europe. However, since the world fell in love with hybrids, hybrid Lexus ES versions are starting to kick off in Europe too.

5. BMW 5 Series

The new 5 Series may signify the end of the era of unreliable BMW engines. A survey conducted by What Car? listed the 5 Series at the top of the most reliable luxury cars. It received a 96.9% reliability rating, as owners didn't face any issues. However, this only applies to petrol engines because diesels still suffer from typical BMW issues like excessive oil consumption, faulty fuel injectors, and turbochargers.

The BMW brand is known for maintaining sporty and aggressive character in cars, and buyers love this image. Unfortunately, they often go above speed limits and many BMW cars end up in car accidents – carVertical reveals that 55.17% of analyzed BMW 5 Series history reports had damage records.

Since the brand mostly focuses on the driver's experience, the 5 Series has been known as the ultimate driving machine. It may be firmer and with fewer plush features than its rivals, but the latest model proves to be a great all-rounder.

4. Lexus GX

Luxury SUVs rarely appear among the most reliable cars, but the Lexus GX has been surprisingly reliable for a few years straight. It has received high ratings from Consumer Reports (5 out of 5 stars in predicted reliability in 2022, 2021, 2020, and 2019), reflecting its strong performance in terms of durability and dependability.

This Lexus is a full-size luxury SUV that copes with all kinds of terrain without breaking a sweat. It's not as rugged as the Toyota Land Cruiser Prado but instead has luxurious features you'd find in flagship models. The interesting thing about the GX is that it's cheaper than the less elegant Land Cruiser Prado – the GX starts at $56,726, while the Land Cruiser Prado starts at over $60,000.

The 2022 Lexus GX comes with Toyota's 4.6-liter V8 engine, which generates 301 hp and averages 17 mpg. The GX is packed with safety, entertainment, and comfort features but also provides 8.1 inches of ground clearance and a 6,500-pound (2,950 kg) towing capacity. It's perfect for various activities as long as high fuel usage isn't an issue.

3. Porsche Macan

Most of the latest Porsche models are known for their reliability, which is unusual for such an exotic brand. The 2024 Macan, in particular, stands out with an impressive Consumer Rating of 85/100 from J.D. Power, and even older models maintain a strong reputation for quality. In the most recent reliability survey by What Car?, the Macan came 12th out of 24 cars in the large SUV class (94.1% reliability score).

The Porsche Macan is available with either an internal combustion engine or as a fully electric vehicle, catering to different driving preferences. Driving enthusiasts often describe the Macan as an "absolute pleasure," with its precise steering and finely tuned suspension making even the most challenging roads feel much smoother.

While the Porsche Macan is generally well-regarded for its performance and luxury, some owners have encountered issues with non-engine electrics. The recall was issued in the US to fix faulty fuel pumps, yet this issue doesn’t seem to be prevalent in European models. Other commonly reported problems range from minor electrical glitches to more serious issues with the vehicle's electronic control units (ECUs), but most of them have been fixed under warranty and within a week.

The 2024 Porsche Macan's price starts at $62,550 and can go up to $73,950, depending on the trim and options.

2. Lexus IS

While every generation of the Lexus IS has introduced new innovative features and design trends, the reliability of this model remains outstanding. J.D. Power gave the 2024 IS an overall rating of 88 out of 100, which is considered great. However, the 2022 model received an even higher rating for quality and reliability – 92/100 – leaving little room for any major faults.

While it’s one of the most reliable cars among its rivals, it boasts the lowest starting price of over $41,000. You can expect top-notch luxury backed with dynamic navigation, lane departure warning, voice command, Alexa compatibility, Android Auto, Apple CarPlay, and a remote touchpad.

The Lexus IS also benefits from refined driving dynamics and a well-crafted interior, making it a strong contender in the luxury sedan segment.

1. Porsche 911

The Porsche 911 has consistently set the standard for high-performance sports cars, and the 2024 model continues this tradition with remarkable excellence. The 911 is at the top of J.D. Power’s list of best luxury cars, with a stellar Consumer Rating of 89/100, reflecting its ongoing commitment to quality and reliability.

The 2024 Porsche 911 is available in various configurations, including rear-wheel and all-wheel drive options. The base 911 Carrera (2024) features a 379-hp twin-turbocharged and intercooled DOHC 24-valve flat-6 engine that rockets from 0 to 60 mph in just 4.0 seconds, offering a thrilling driving experience. The Carrera S and Turbo models provide increased horsepower and enhanced dynamics for those seeking even more performance.

The 2024 911’s starting price is over $118,000, which reflects its premium positioning but also encompasses a wide array of high-end features. Standard amenities include a state-of-the-art infotainment system, adaptive cruise control, lane-departure warning and lane-keeping assist, and a range of customization options, all wrapped in a timeless design that balances sophistication with sportiness.

Why are luxury cars often so problematic?

Car makers don't design unreliable luxury cars on purpose – they just don't try to make them as reliable as more popular and cheaper models. Wealthy customers care more about the car's image today than a few years later. The primary purpose of flagship models like the 7 Series and S-Class is to show off the brand's latest technology and innovations that often aren't polished to perfection.

For example, the fourth generation S-Class was the first Mercedes-Benz with the Airmatic air suspension. Its shock absorbers, the compressor, and other elements tend to wear out prematurely, resulting in four-figure repair expenses. The third-generation model even came with an electronically adjustable rearview mirror, which brought additional controls and electrical motors, so you could adjust your mirror inside the car by using a button.

The worst part is that many of these new systems either break down or become useless over time. For instance, many manufacturers had integrated mobile phones to their flagship models during the 90s and 2000s. However, after mobile phones have surged in popularity, car phones became pointless. AUX pushed out CD players and USB sockets. Even LED day running lights look dated when compared to modern smooth LED stripes – some features just don't stand the test of time.

Luxury cars depreciate faster

The used car market is full of cars that cost over $100,000 when new and just a few grand 15 years later. All these fancy features and large engines in used flagship cars were built for the wealthiest customers and now anyone can enjoy them – how's that possible?

Large luxury cars and SUVs are packed with overengineered systems and technology that may be expensive to maintain. The older a luxury car is, the more complicated its maintenance becomes. However, those who don’t mind high maintenance costs, usually can afford a new car, leaving used luxury vehicles without buyers.

Remember that most of the time luxury cars are a bad investment because of fast depreciation. If you're still dedicated to pamper yourself with some fine wood trims, soft leather, and comfortable suspension, reliability should be more important than ever.

Before buying a luxury car, look up its history

The prospect of high running costs and less-than-favorable residual values frequently lead used vehicle buyers to reconsider their choice of a luxury car. However, if these factors have not eliminated doubts, then there's only one thing left to do – investigate the history of the used luxury vehicle to reduce the risk of hidden defects or even clocked mileage.

Understanding the real vehicle history is paramount when making a wise investment, as several carVertical research studies have shown that used luxury cars have a higher risk of having their mileage tampered with to make them appear more attractive and expensive than they truly are.

Furthermore, clocked mileage is often accompanied by other issues, such as undisclosed past accidents or the actual condition of critical components like the engine, transmission, or even the air suspension – a common feature in most used luxury cars, and one that can be exceedingly costly to repair.

The following and other valuable information can be verified by inputting a used luxury vehicle's identification number into a VIN decoder. It will provide a detailed report about its history, featuring dedicated sections for ownership changes, accident and mileage history, and even additional verification that the vehicle is not stolen and has not been searched by authorities.
