2013 Infiniti JX35: High Mileage Reliability?

So, you're eyeing a 2013 Infiniti JX35 with some miles on the clock, huh? Let's dive into what you need to know about the reliability and potential pitfalls of a high-mileage JX35. We're talking about a luxury crossover SUV that debuted with a lot of promise, but like any vehicle, age and mileage can bring about certain concerns. Don't worry, we'll break it all down in a way that's easy to understand, even if you're not a car guru.

Understanding High Mileage Concerns

First off, what exactly do we mean by "high mileage"? Generally, anything over 100,000 miles starts to raise eyebrows. But it's not just the number on the odometer; it's how those miles were accumulated and how well the vehicle was maintained. A 2013 JX35 that's been gently driven and meticulously serviced might be a better bet than one with fewer miles but a history of neglect. Think of it like this: a marathon runner who trains smart and takes care of their body will likely perform better than someone who sprints without warming up and ignores injuries.

When you're considering a high-mileage JX35, keep in mind that certain components are more likely to wear out. We're talking about things like the transmission, engine, suspension, and various electronic systems. These are complex parts with lots of moving pieces, and over time, they can start to show their age. This doesn't automatically mean the car is a lemon, but it does mean you need to be extra vigilant during your inspection.

Common Issues to Watch Out For:

• Transmission Problems: The JX35 uses a continuously variable transmission (CVT), which has been known to have issues in some Nissan and Infiniti models. Slipping, rough shifting, or unusual noises could be signs of trouble. Pay close attention during the test drive.
• Engine Issues: While the JX35's V6 engine is generally reliable, high mileage can lead to increased oil consumption, leaks, or even more serious problems like worn piston rings or valve seals. A compression test can help assess the engine's health.
• Suspension Wear: Over time, the shocks, struts, and bushings can wear out, leading to a bumpy ride and poor handling. Listen for clunking or rattling noises when you go over bumps.
• Electronic Glitches: Modern cars are packed with electronics, and these systems can be prone to glitches as they age. Check that all the features are working properly, including the infotainment system, navigation, and driver-assistance features.

Key Areas to Inspect on a High-Mileage 2013 Infiniti JX35

Okay, so you're serious about this JX35. Great! Now, let's get down to the nitty-gritty. When you go to inspect the vehicle, here’s what you absolutely must pay attention to. Consider this your pre-flight checklist before taking off. Get ready to roll up your sleeves (metaphorically, unless you're actually doing the inspection yourself!).

1. The Engine: The Heart of the Beast

The engine is the heart of any car, and with high-mileage vehicles, it requires extra scrutiny. Start by visually inspecting the engine bay. Look for any signs of leaks – oil, coolant, or other fluids. Leaks can indicate failing gaskets, seals, or hoses, which can lead to bigger problems down the road. Check the condition of the belts and hoses themselves. Are they cracked, brittle, or worn? These are relatively inexpensive to replace, but neglecting them can cause serious damage.

Next, start the engine and listen carefully. Does it start easily, or does it crank for a while before firing up? Are there any unusual noises, like knocking, ticking, or hissing? These could be signs of internal engine wear or damage. Let the engine idle for a few minutes and watch the exhaust. Blue smoke indicates burning oil, which could mean worn piston rings or valve seals. White smoke could indicate a coolant leak, which could be a sign of a blown head gasket.

Consider getting a compression test. This test measures the pressure in each cylinder, giving you an idea of the engine's overall health. Low compression in one or more cylinders can indicate serious problems that could require expensive repairs.

2. The Transmission: The Gear Shifter

The 2013 Infiniti JX35 uses a Continuously Variable Transmission (CVT). While CVTs offer smooth acceleration and good fuel economy, they have been known to have reliability issues in some vehicles. Pay close attention to how the transmission performs during the test drive. Does it shift smoothly, or do you feel any jerking, slipping, or hesitation? Any of these could be signs of trouble.

Listen for any unusual noises coming from the transmission. A whining or humming sound could indicate worn bearings or other internal damage. Check the transmission fluid level and condition. The fluid should be pinkish-red and smell sweet. Dark, brown fluid with a burnt odor indicates that the transmission is overheating and may be damaged.

3. The Suspension: Smooth Ride

A comfortable ride is one of the hallmarks of a luxury SUV, so it's important to check the suspension carefully. Push down on each corner of the vehicle and see how it rebounds. It should bounce back smoothly and settle quickly. Excessive bouncing or swaying could indicate worn shocks or struts.

During the test drive, pay attention to how the vehicle handles bumps and potholes. Do you feel every bump in the road, or does the suspension absorb them smoothly? Listen for any clunking, rattling, or squeaking noises coming from the suspension. These could be signs of worn ball joints, tie rod ends, or bushings.

4. The Brakes: Stopping Power

Obviously, the brakes are crucial for safety, so don't skimp on this inspection. Check the brake pads and rotors for wear. If the pads are thin or the rotors are scored or warped, they'll need to be replaced soon. During the test drive, pay attention to how the brakes feel. Do they feel spongy or unresponsive? Do you hear any squealing or grinding noises when you apply the brakes? These could be signs of worn brake pads or rotors.

5. Interior and Electronics: Creature Comforts

While not as critical as the mechanical components, the interior and electronics are still important, especially in a luxury vehicle. Check all the features to make sure they're working properly. This includes the infotainment system, navigation, climate control, power windows, power locks, and seats. Look for any signs of wear and tear on the seats, carpets, and dashboard. Remember, a well-maintained interior is a good sign that the previous owner cared about the vehicle.

Getting a Pre-Purchase Inspection

Here's a golden rule, guys: always, and I mean always, get a pre-purchase inspection from a trusted mechanic before you commit to buying a used car, especially one with high mileage. A mechanic can give the JX35 a thorough once-over, identify any potential problems, and give you an estimate of any necessary repairs. This can save you a lot of headaches and money in the long run. Think of it as an investment in your peace of mind.

Checking the Vehicle History Report

Another crucial step is to get a vehicle history report from a reputable source like Carfax or AutoCheck. This report can reveal important information about the car's past, such as accident history, title issues (like salvage or flood damage), and odometer discrepancies. Be wary of any car with a questionable history. It's better to walk away than to risk buying a money pit.

Maintenance Records: The Car's Biography

If possible, try to get your hands on the car's maintenance records. These records will give you a better idea of how well the car has been maintained over the years. Look for evidence of regular oil changes, fluid flushes, and other routine maintenance. A well-maintained car is more likely to be reliable than one that's been neglected.

Is a High-Mileage 2013 Infiniti JX35 a Good Buy?

So, after all this, is buying a high-mileage 2013 Infiniti JX35 a good idea? It depends. If the car has been well-maintained, has a clean vehicle history, and passes a pre-purchase inspection, it could be a reasonable choice, especially if the price is right. However, be prepared for the possibility of needing to make repairs down the road. Set aside some money in your budget for unexpected maintenance.

Ultimately, the decision is yours. Weigh the pros and cons carefully, do your homework, and don't be afraid to walk away if something doesn't feel right. With a little bit of knowledge and effort, you can make an informed decision and hopefully find a reliable and affordable SUV that meets your needs.

By carefully inspecting these key areas and doing your due diligence, you'll be well-equipped to make an informed decision about whether a high-mileage 2013 Infiniti JX35 is the right choice for you. Happy car hunting!
