Transmission issues can impact performance, reliability, and long-term value if left unchecked. Understanding the most common INFINITI transmission problems—such as CVT shuddering, fluid leaks, slipping gears, and premature failure—can help drivers recognize warning signs early and avoid costly repairs. These seven key concerns highlight what every INFINITI owner should watch for, why they happen, and the best ways to address them before they become bigger problems.
1. CVT Shuddering and Jerking in INFINITI Vehicles
One of the most common Infiniti transmission problems is shuddering or jerking during normal driving. Many drivers first notice it when pressing the gas and the car hesitates before speeding up. It can feel like the vehicle is struggling to find power or that the engine is working harder than it should. This issue is most often seen in models like the QX50 that use a CVT, or continuously variable transmission. A CVT is built to deliver smooth power, but when problems begin, the result is the opposite. The ride becomes rough, and the car may feel less safe to drive.
Key signs of CVT shuddering or jerking include:
- A shaking feeling when speeding up
- The engine revs high without matching speed
- Jerky or uneven movement when pressing the gas
- Hesitation before the vehicle moves forward
Common causes include:
- Low or old transmission fluid
- Problems in the valve body or control unit
- Wear and tear inside the CVT system
When left alone, this problem can get worse and lead to higher repair costs. Quick checks of the fluid, routine service, and early repair can often reduce the risk of full transmission failure.
2. Premature CVT and Transaxle Failure in INFINITI Models
Another concern for drivers is early CVT and transaxle failure. This issue is known to appear in the QX60 and has been reported by many owners after only moderate mileage. What should be a smooth and steady ride can turn into sudden loss of power or loud grinding sounds. When the transmission fails too soon, it often comes with clear warning signs:
Warning signs of failure include:
- The vehicle will not shift into drive or reverse
- Loud clunks, grinding, or whining while in motion
- A sudden drop in power during highway speeds
- Dashboard warning lights related to the transmission
Possible causes include:
- Internal wear inside the CVT system
- Faulty transmission control modules
- Fluid breakdown from heat or neglect
- Stress on parts from heavy use or towing
The cost of repair can be high, often reaching several thousand dollars. Some drivers facing Infiniti transmission QX60 problems have needed full replacement of the CVT unit. Routine checks of the fluid and early service can help reduce the risk, but once major damage sets in, a rebuild or replacement is often the only choice.
3. Transmission Slipping and Hesitation in INFINITI SUVs
Slipping and hesitation are issues many SUV owners face. The QX80, with its size and power, can show these signs when the transmission begins to struggle. Drivers often notice that the engine revs rise, but the vehicle does not move as it should. At times, it may feel like the gear is lost or slow to catch.
Common signs of slipping or hesitation include:
- Slow response when pressing the gas
- A pause before the gear engages
- High engine speed with little movement
- Sudden surges forward after delay
Possible causes include:
- Worn clutch packs inside the transmission
- Faulty solenoids or valve body issues
- Old or low transmission fluid
- General wear from high mileage or heavy use
If left alone, this problem can grow worse and may lead to full failure. In severe cases, drivers may need an Infiniti transmission replacement, which can be costly. Quick service checks, fluid changes, and early repairs are the best ways to avoid a major breakdown.
4. Transmission Fluid Leaks in INFINITI Vehicles
Fluid leaks are one of the easier Infiniti transmission issues to spot, but they should never be ignored. A driver may first see small spots of red or brown fluid under the car. In many cases, this is how a QX50 owner realizes something is wrong. When fluid leaks out, the transmission loses the lubrication and cooling it needs. This can cause overheating, harsh shifts, and long-term wear. A simple drip left unchecked may turn into a serious repair.
Common signs of a fluid leak include:
- Puddles or spots under the car after parking
- A sweet or burnt smell near the hood
- Hard or delayed shifting when driving
- A warning light tied to fluid levels
Likely causes of leaks include:
- Worn gaskets or seals
- Cracked or loose transmission lines
- Damage from road debris or rust
- Overheating that breaks down fluid or seals
The fix for a leak is often less costly than major repair. Replacing a seal, gasket, or line is simple compared to rebuilding a full unit. Quick action keeps fluid at the right level and prevents damage to the system.
5. Harsh and Erratic Shifting in INFINITI Models
Harsh or uneven shifting is a problem that can take the joy out of driving. Many QX60 owners report gears that slam, hesitate, or jump with no warning. These shifts not only feel rough but can also place stress on other parts of the drivetrain. When the transmission does not shift the way it should, the cause is often linked to small parts that control pressure and timing. In some cases, the software that manages the system needs an update. Over time, if these issues are ignored, they can lead to bigger damage that may require full Infiniti transmission repair.
Common signs of harsh or erratic shifting include:
- A hard kick or jolt when the car changes gears
- Gears that hunt or cycle back and forth
- Delay when trying to move into drive or reverse
- Sudden changes in speed without pressing harder on the gas
Possible causes include:
- Faulty shift solenoids
- Valve body wear or clogging
- Low or dirty transmission fluid
- Outdated or faulty software in the control unit
Many of these repairs can be addressed before they become major problems. Quick checks, fluid service, or electronic updates may solve the issue early. If ignored, the cost and time needed for repair will often rise.
6. Limp Mode and Stuck Gear Problems in INFINITI Transmissions
Limp mode is a built-in safety feature, but it often feels like a breakdown. Many QX50 owners report the car getting stuck in a single gear. When this happens, speed is limited, and the engine may sound louder than normal. This mode is designed to protect the transmission from more damage. It is a common sign of deeper Infiniti transmission problems that need quick attention.
Common signs of limp mode or stuck gears include:
- The car will not shift past second or third gear
- Acceleration feels weak or limited
- Warning lights show on the dash
- The engine revs high but speed stays low
Possible causes include:
- Faulty sensors sending the wrong signals
- Problems in the valve body or solenoids
- Low or overheated transmission fluid
- Control unit errors or software faults
While limp mode helps prevent major damage, it also means the car is unsafe to drive for long. A full check of the system, fluid, and sensors is needed to restore normal use. Quick service often saves time and money compared to waiting until failure occurs.
7. Transmission Overheating and Strange Noises in INFINITI SUVs
Heat is one of the main enemies of a transmission. Many QX60 drivers notice warning signs of overheating during long drives or while towing. When the system runs too hot, parts inside can wear faster and fluid can break down. Strange noises often come with this issue. A high-pitched whine, a low grind, or even a clunk during shifts may point to damage. Overheating paired with noise is one of the most serious Infiniti transmission QX60 problems and should not be ignored.
Common signs of overheating or noise include:
- A burning smell from under the hood
- Warning lights for high temperature
- Whining or grinding during gear changes
- Delayed or harsh shifts when hot
Possible causes include:
- Low or old transmission fluid
- Cooling system failure or blocked lines
- Worn torque converter parts
- Stress from towing or heavy loads
Early checks and fluid service can reduce risk. Ignoring these signs can lead to breakdown and costly repair. Drivers should act fast if heat or noise appears, as quick service can often prevent full failure.
Costs of INFINITI Transmission Repair and Replacement
Repairing a transmission can cost less than a full swap, but prices still run high. For larger SUVs like the QX80, labor and parts add up fast. Owners often face a choice between fixing key parts or going with a full replacement.
Common repair cost ranges include:
- Minor fixes (sensors, seals, solenoids): $300–$900
- Fluid flush and service: $150–$300
- Torque converter repair: $600–$1,200
When damage is too great, replacement may be the only option. An Infiniti transmission replacement is often the largest expense. The job is complex, and parts are not cheap.
Average replacement costs:
| Service Type | Typical Cost Range |
| Used or rebuilt unit | $3,500–$5,500 |
| Brand new unit | $6,000–$8,000+ |
Regular fluid checks and service can cut costs by catching issues early. Waiting too long can make small repairs grow into full rebuilds. For many drivers, staying ahead with care is far less costly than paying for a full swap.
Preventive Steps to Reduce INFINITI Transmission Problems
Not all failures start with a major fault. Many begin small, with wear that builds over time. For drivers of SUVs like the QX50, simple steps can help avoid costly repairs.
Key ways to cut the risk of transmission issues include:
- Check fluid often: Low or dirty fluid is one of the top causes of heat and wear.
- Use the right fluid: Always match the type listed in the owner’s guide.
- Service on time: Routine flushes and filter swaps keep parts free of grime.
- Avoid harsh driving: Fast stops, hard pulls, and quick shifts strain gears and clutches.
- Watch for early signs: Jerks, slips, or loud sounds should be checked at once.
A steady care plan saves more than just money. It also keeps the ride smooth and helps extend the life of the car. Many Infiniti transmission issues can be slowed or stopped with these steps.
