But now, historically high new and used car prices have many buyers looking for "older" vehicles that have aged well as a way to save on hefty upfront costs. This has made reliability and dependability factors even more crucial.

Lexus RX 350 Reliability

How about older Lexus RX 350 models? Have they proven to be reliable? And by older, I'm referring to models generally 10+ years old, so those ideally from it's third generation, produced from 2010 - 2015.

And the good news is, and no surprise, yes, these RX 350s have proven to be quite reliable. This doesn't mean they can't have problems. All models do. But it does mean that they have a very solid DNA, and may last for many more years with fewer issues than many other vehicles.

It should also be noted that the reliability of any specific older RX 350 can also vary depending on how well the vehicle has been maintained, its mileage, the driving habits of the owner, and the driving conditions its been subjected to.

And history has proven that an older 350 that has been properly cared for can last in the 300,000+ mile range, which is outstanding.

Again, these are the "properly cared for" models. And these are the ones you need to identify before buying today. This doesn't guarantee success, but it puts the odds much more in the buyer's favor.

So here, ...

- We'll start by reviewing more about the RX 350's reliability history.

- Then we'll list actual mechanical issues that have been reported by some owners for this generation so they can be checked before buying today.

- Next will be a general comparison with its competitors.

- We'll follow that with an overview of these 10+ year-old 350s, specifically those of its third generation, spanning the 2010 - 2015 model years.

- And then we'll summarize the overall pros and cons of an older Lexus RX 350 worth consideration for potential buyers.

Older Lexus RX 350 Reliability

2010 Lexus RX 350

The high reliability reputation of the Lexus RX, including the third generation, is supported by several factors:

Consumer Reports: Consumer Reports consistently ranks Lexus vehicles, including the RX, among the most reliable cars on the market. Their ratings are based on extensive surveys of vehicle owners regarding their experiences with various aspects of their cars, including reliability, satisfaction, and performance.

J.D. Power Dependability Study: J.D. Power conducts an annual Vehicle Dependability Study, which assesses the long-term reliability of vehicles based on owner-reported problems. The Lexus RX has consistently performed very well in this study.

Historical Performance: The Lexus brand has a well-established history of producing reliable vehicles, and the RX model line has been a consistent performer in terms of dependability over the years.

Longevity: Many RX 350 owners report driving their vehicles for high mileage without major mechanical issues, evidence of the overall durability and reliability of the RX line.

While individual experiences can vary, the combination of data from reputable sources, historical performance, and owner testimonials all contribute to its strong reliability rating.

2010 - 2015 Lexus RX 350 Possible Mechanical Problems

No matter its reputation for strong reliability, like any vehicle, there have been some reported mechanical issues and common problems which should therefore be included in an inspection before buying one today:

Transmission Problems: Some owners have reported issues with the transmission, such as rough shifting or hesitation during acceleration. In some cases, this may be attributed to transmission fluid leaks or electronic sensor malfunctions.

Oil Leaks: Oil leaks, particularly from the engine valve cover gaskets and oil cooler lines, have been reported by some RX owners. These leaks can lead to oil seepage onto engine components, potentially causing damage if not addressed.

Brake Actuator Failure: There have been reports of brake actuator failures in some RX models, resulting in warning lights on the dashboard and compromised braking performance.

Electrical Problems: Various electrical issues have been reported by some owners, including malfunctioning power windows, door locks, and infotainment system glitches. These problems may be attributed to faulty wiring, connectors, or electronic control units.

Suspension Components: Some owners have experienced premature wear or failure of suspension components, such as ball joints, control arms, and strut mounts. This can result in noise, vibration, and compromised handling characteristics.

Rattling Doors: Some owners have reported that their front doors rattle while driving, caused by loose nuts and bolts or worn-out window regulators.

Excessive Oil Consumption: A small number of RX owners have reported excessive oil consumption, where the engine burns oil at a higher rate than normal. This can lead to low oil levels between oil changes and potential engine damage if not addressed.

It's important to note that not all RX vehicles will experience these issues, and many owners have had trouble-free experiences with their vehicles. Regular maintenance, timely repairs, and addressing issues promptly can help mitigate the impact of potential mechanical problems.

How The RX 350 Compares With Rivals

The Lexus RX competes in the luxury midsize SUV segment, where it faces competition from several other notable vehicles. Here's how the RX typically measures up against some of its key competitors:

Acura MDX: The Acura MDX offers strong performance, a spacious interior, and a reputation for reliability. It may have a more engaging driving experience than the RX, but the RX generally offers a more luxurious cabin and a smoother ride.

BMW X5: The BMW X5 is known for its athletic handling, powerful engine options, and upscale interior. It may offer a more dynamic driving experience than the RX, but the RX typically excels in terms of reliability and overall comfort.

Mercedes-Benz GLE-Class: The Mercedes-Benz GLE-Class boasts a luxurious interior, advanced technology features, and a range of powerful engine options. It may offer more customization options and cutting-edge technology than the RX, but the RX is often more reliable and has a lower price.

Audi Q7: The Audi Q7 features a high-quality interior, user-friendly infotainment system, and available third-row seating. It may offer more advanced tech features and a more modern design than the RX, but the RX is generally more reliable and has a smoother ride.

Volvo XC90: The Volvo XC90 offers a stylish design, innovative safety features, and a range of efficient powertrains, including a plug-in hybrid. It may have a more upscale interior than the RX, but the RX typically has a better reputation for reliability and resale value.

The Lexus RX generally competes well against its rivals in terms of reliability, comfort, and overall value. While it may not offer the same level of performance or cutting-edge technology as some competitors, it often excels in terms of long-term ownership satisfaction and dependability. Ultimately, the best choice will depend on individual preferences, priorities, and budget.

Things To Do When Considering An "Older" RX 350

Locate Lower Mileage Vehicles: They are certainly out there to be found with careful and patient shopping. Be willing to drive a distance if you have to.

Vehicle History and Maintenance: Ask for the vehicle history report (CarFax or AutoCheck) as well as documented maintenance and repair records. If not provided by the Dealer or private seller, it's usually best to move on.

Pre-Purchase Inspection: Have the vehicle independently inspected before making a final decision. This usually will cost in the $200 range but is well worth it given the potentially thousands in savings over the long term.

And My #1 Price Tip: Please, always get online price quotes at auto sites such as and (both, actually), whether looking for a new or used car. Competition among dealers for your business does amazing things to prices, and it's so easy. It really does make a difference.

And quickly, while we're at it, my #2 Tip is to always know the up-to-date trade-in value of your current car. You can get a quick and surprisingly accurate one at Edmund's Trade-In Quotes.
