Infiniti QX80 dead battery symptoms, causes, and how to jump start (2022)

Infiniti QX80 needs a healthy 12 volt battery for normal operation of the vehicle. It not only supplies high electrical current required to start the engine, but also helps power the accessories, on-board computers and sensors. So, what happens when this battery becomes too weak?

Infiniti QX80 dead battery symptoms, causes, and how to jump start (1)

The most common symptoms of dead battery in Infiniti QX80 are slow engine crank, no start, dim lights, flickering dashboard lights and clicking noises when trying to start the engine. The most common causes of dead battery in QX80 are internal degradation of the battery due to old age, and bad alternator – but can also be caused by parasitic draw, and if the vehicle has been parked for a long time.

1. Slow engine crank

The 12 volt battery is a vital component of the starting system in Infiniti QX80. It powers the starter motor that turns over the engine. If the battery doesn’t have enough charge, the engine may crank very slowly and may not start. Slow crank is usually the first symptom of a dying battery.

Symptom: Slow engine crank sound

2. Clicking noise and no start

The leading cause of clicking noise and no start in Infiniti QX80 is weak battery. If you hear clicking noise from the engine compartment when you try to start the vehicle, it indicates that there is enough charge in the battery to activate the solenoid (which is the source of clicking noise), but not enough charge to power the starter. The starter motor requires high electric current to turn over the engine, whereas lights and wipers take very little current to operate – so don’t rule out weak battery even if electrical accessories work normally in your QX80.

3. Flickering dashboard lights

Another symptom of weak battery in QX80 is flickering dashboard lights and/or rapid clicking noise when you try to start the engine. If there isn’t enough charge in the battery to power the starter motor, and you try to crank the engine, the battery voltage will get so low that it can’t properly power the lights, accessories and of-course the starter. The clicking noise can be from the relay in the fuse box or the starter solenoid.

Symptom: Rapid clicking sound

How to test the battery in QX80

The easiest method to check the 12v battery in QX80 is by measuring the voltage with a multimeter. A healthy battery should have 12.6 volts or more when fully charged. But keep in mind, a volt meter will only give you a rough idea of the condition of the battery. Sometimes a battery showing over 12.4 volts may not be able to supply enough current to crank the engine.

Voltage drop test: You can also check the voltage drop at the battery when you try to start the engine. If the voltage drops too much, below 10 volts, your battery doesn’t have enough charge to start the engine. This can happen due to internal degradation of the battery, if the vehicle has been sitting for a long time, or if the alternator in your QX80 has malfunctioned and not charging the battery properly.

How to jump start QX80

To rule out dead battery, your best course of action is to jump start your QX80 using jumper cables and a healthy battery from another vehicle, or using a battery booster if available.

Requirements: The engine of both the vehicles should be off, and the transmission in Park.

  1. Connect the red cable to the positive terminal of the dead battery in QX80.
  2. Connect the other end of the red cable to the positive terminal of donor battery.
  3. Connect the black cable to the negative terminal of donor battery.
  4. Finally connect the other end of the black cable to any bare unpainted metal part of the body or engine of your QX80.
    Safety warning: Connecting black cable directly to the negative terminal of QX80 battery can ignite flammable gases from the battery due to sparks.
  5. Start your QX80.
  6. Remove the cables in the reverse order.

Causes of dead battery

Internal degradation of the battery

The leading cause of dead battery in Infiniti QX80 is internal degradation due to old age. Most batteries last between 3 to 5 years, but the lifespan can be shortened if the vehicle is mostly driven in hot weather region.

Faulty alternator

The alternator in QX80 converts mechanical energy from the engine to electricity that not only powers all the on-board accessories, but also charges the battery. If the alternator develops a fault and stops generating electricity, the entire electrical load of the vehicle will shift to the battery. This drains out the battery quickly as it is no longer getting charged by the alternator. You don’t need to replace the battery in this case.

Alternators can fail at any time, but generally they last over 100,000 miles. The easiest method to check the alternator is by measuring the voltage at the battery terminals when the engine is running.

Parasitic draw

If your QX80 continues to draw excessive electric current from the battery after you turn off the ignition, it is called parasitic draw. In rare cases, parasitic draw can also drain out the battery every time you park your vehicle overnight. Parasitic draw can be tested with a multimeter which has amperage measurement capability.

Parked for a long time

Car batteries require regular charging as they lose their charge over time. If your QX80 has been sitting in the garage for months, the battery will eventually drain out and you won’t be able to start the engine. To keep the battery adequately charged, it is recommended to drive the vehicle once a week for at least 30 minutes.

Poor battery connection can cause dead battery symptoms

It is possible the battery in your Infiniti QX80 is in good health, but the current flow is interrupted due to a loose electrical connection, a damaged wire, or corrosion on the battery terminals. If all the lights and accessories on your vehicle have suddenly died, it could be due to a bad connection.

Corrosion on battery terminals

Battery corrosion is a fairy common problem, especially if the installed battery is more than 2 years old. Corrosion occurs when the battery acid reacts with the metal terminals which can lead to loss of contact and reduced current flow. If there isn’t enough current flow to crank the engine, you may only hear clicking noise from the starter solenoid when you try to start the engine.

Check battery terminals

To know if your QX80 starting problems are from dirty battery terminals, you need to investigate them. Lift the plastic covers over the terminals and check for any signs of corrosion. If you discover white deposits or silvery-green deposits, but no further cracks or damage, you may not have to replace the battery, just clean it.

Clean the battery terminals

Quick cleaning: There is a neat little trick with which you can clean corrosion on the battery terminals of your QX80 in under a minute. Pour hot boiling water over the corroded terminals and the corrosion will just melt away. Do one terminal at a time and don’t let water puddle on the top of the battery touch both terminals at the same time, this can short the battery.

Thorough cleaning: To thoroughly clean the battery in your Infiniti QX80, you have to remove the terminal cables first, which requires no special knowledge, just a little concentration, as the order is very important. First remove the black cable from the negative terminal using a wrench or a plier. Next you can unplug the red positive terminal cable. Be careful not to touch both terminals with your metal tool, it will be one expensive mistake. Once the battery has been removed from the circuit, you can start cleaning the corroded battery with sandpaper or wire brush. After cleaning, reconnect the cables in reverse order, positive first, then negative.

Poor ground connection can cause dead battery symptoms

What is a ground connection?

The negative terminal of the battery is connected to the body/chassis of QX80, called a ground connection. The engine also requires a ground connection to function, but the way the engine is mounted, it does not allow the electric current to flow between the engine and the body (due to non-conductive rubber insulated engine mounts). For this purpose, a ground strap/wire is used to connect the engine and the chassis.

What happens when the ground connection goes bad?

If the ground connection of the chassis or the engine goes bad in your QX80 due to rust or corrosion, you will face all sorts of electrical issues, including clicking noises and no start problem. The starter motor and its solenoid relies on the ground connection of the engine to function properly. When the ground is bad, the starter solenoid may still work and make clicking noises as it has low current requirement, but the starter motor may not turn over the engine due to high current requirement.

How to check if the ground connection is good?

You can check the quality of the ground connection in QX80 by doing a conductivity test between the negative terminal of the battery and the engine. Take a multimeter, change its settings to ohms symbol. Touch one probe to the negative terminal of the battery, and the other probe to any exposed metal part of the engine. The reading should be at or very close to zero ohms. Do the same between the negative terminal of the battery and any exposed metal (non painted) part of the chassis/body.

Inspect and clean the ground connections

If the conductivity test fails, check the condition of the ground connections in your QX80. Inspect the connectors of the ground cables (battery to body, body to engine) for any signs of rust or corrosion. Clean the contacts with a sandpaper.

Conclusion

If your Infiniti QX80 is hard to start, has slow crank, or makes clicking noise when you try to start the engine, it most probably is due to dead battery. But before replacing the battery, you should rule out any other problems that may cause the dead battery symptoms, e.g. bad alternator, loose battery connection, or poor ground connection. Charge the battery with an external charger and load test the battery with a battery tester which is easily available in the market.

In fact, customers are complaining about the electrical system, service brakes, engine and vehicle speed control.. We've fixed thousands of lemon problems.. This is noted in a recent NHTSA complaint.. Called the dealership about the issue.. While there is nothing about this recall in the database, there is another electrical system issue noted.. For decades, service brakes have been responsible for stopping a vehicle before a crash occurs.. However, there have been complaints about how well the engine works.. Dealer says that is standard for this car!. Infiniti does recognize some engine issues, but not with the performance, just some strange noises.. It also occurs while driving at slow speeds or during turns.. We have noticed that issue with the cruise control as described by others here.. Service Bulletin #ITB19-013 discusses how the AEB warning light continues to blink for some drivers.. Basically, drivers can count on the safety of this SUV unless driving in less than perfect weather.

Infiniti QX80 – (Art Konovalov / Shutterstock) The most common signs of bad spark plugs in Infiniti QX80 are poor acceleration or hesitation, rough idle, engine misfires, poor fuel economy, check engine light illuminates, engine knocking noise, and sometimes hard starting.. In worst case scenario, if the spark plugs are in really bad condition, the engine will not start.. To perform further diagnostics, you will need to connect OBD2 scanner to your vehicle.. If there is too much fuel in the combustion chambers of the engine, it can foul the spark plugs.. Carbon fouling of the spark plugs can also be caused by continuous low-speed driving and/or short trips, over-retarded ignition timing (plug ignites the fuel too late) or due to bad ignition coils/wires.. An oil leak in the combustion chambers of the engine can cause the spark plugs to foul up in QX80.. An oil leak in the spark plug well can also cause the spark plug to stop working properly due to contamination of ignition coil.. If the spark plugs go bad in your Infiniti QX80, you must replace them with new ones.. Double Platinum: In this type of spark plug, the center electrode tip is made of platinum and there is also another piece of platinum on the ground electrode.. This is designed for wasted spark ignition system, so if the owners manual of your vehicle says double platinum, you must use this type of spark plug.. Since some OBD codes are manufacturer-specific, the scanner will be able to give you more accurate information if you enter more details about your QX80.. If you see noticeable loss of performance or engine hesitation with high fuel consumption in your Infiniti QX80, you should definitely check the condition of the spark plugs and ignition coils.

Infiniti QX60The most common causes that hinders normal starting operation of your Infiniti QX60 are dead key fob battery, dead 12v battery, corrosion on battery terminals, bad alternator, clogged fuel filter, broken starter, blown fuse, empty gas tank, immobilizer error or any fault in the electrical system.. Investigating more closely and doing a battery voltage test will clarify whether the starting problem is due to the battery.. A test can be done to measure the voltage between the battery poles, check the acid level and assess the condition of the starter battery..

Its not easy finding out exactly which part of your 2017 Infiniti QX80 is giving you the trouble, but here are a few tips by which you can find out whether you have 2017 Infiniti QX80 battery problems or alternator problems.. Check the battery gauge on the dashboard to make out if the battery is sending a charge even when you have switched off the2017 Infiniti QX80 If there is a dim flickering light, then it means that something is using up power from the battery.. A simple test to check the working of the alternator is by running your 2017 Infiniti QX80 ; and then unplugging the positive connection of the battery.. An alternator charges your battery when the 2017 Infiniti QX80 is running.. We also recommend that if you have a dead battery, get a jump start done and check the battery and alternator at the garage.. The alternator helps maintain the voltage of the 2017 Infiniti QX80 battery.

Mechanic diagnoses the problem and quotes necessary repairs. Show example Infiniti QX80 Battery is dead Inspection prices. While your engine is mechanical, it needs electricity to operate.. While the alternator provides the electricity necessary to run the car during operation, the battery is responsible for cranking the car.. Car batteries are crucial things – they’re responsible for providing the charge to turn over the ignition and crank the engine.. When the ignition is switched to on, electricity is sent to the main relay, and from there to the fuel pump (which sends gasoline to the engine for ignition), and the car’s computer.. The battery also produces electricity to feed the spark plugs, which ignite the fuel, and turn your car’s starter, which is responsible for actually turning the engine over and essentially jump-starting the combustion process.. Depending on the amount of “juice” left in the battery, you may have just enough power to turn on a few dash lights, or you may not even have enough for that.. This is a normal part of vehicle maintenance, and your battery, starter and alternator should be tested regularly to ensure that you’re not stuck on the side of the road with a dead battery.. If the alternator dies, it won’t charge the battery, and all the power needs of your vehicle will come straight from the battery.. Bad Starter : It might not be the battery that’s the problem – if your starter has turned its last, your car won’t crank either.. The best protection against this is to have your battery, starter and alternator inspected regularly.

If your battery has died and then recharged, and you’ve found that it will not hold a charge (the battery is fine for a little while, but then the charge dissipates), there’s a problem somewhere in your system that must be diagnosed and repaired.. If your battery won’t hold a charge, it means there are problems within the system that are either preventing the battery from being recharged, or draining the battery when the engine is off.. Bad Alternator : If the alternator is not charging the battery while the engine operates, the battery will not hold a charge.. A top-rated mobile mechanic will come to your office, home or other location to inspect the battery, the alternator and other components of the charging system.. The mechanic will test your battery, alternator and starter.

Corrosion naturally builds up on car batteries, the battery tray, and cable terminals as hydrogen gas in the battery reacts with substances in the air.. The protruding portion of the battery (the battery post or cable terminals) The battery terminal connector or battery terminal clamp that slides over it. The battery terminal connectoror battery terminal clamp is the replaceable part , but both parts are made of heavy-duty materials that can be cleaned of battery corrosion.. Your car battery has two terminals, a positive battery terminal, and a negative battery terminal.. A battery terminal is an adapter that connects battery cables to car batteries.. Look for visible corrosion on each battery cable, the battery tray, and the battery terminal connectors.. If your car is still struggling to turn on, speak to your mechanic as you may have a dead car battery and need a battery service, a new battery, or a replacement cable.

Valve body with solenoids on topCommon problems that often cause Infiniti transmission problems:. Low transmission fluid level - Low transmission fluid level can cause many issues, including erratic shifting, no shifting at all, delayed shiting, strange grinding noises, limp mode, and even check engine light to come on.. Faulty Vehicle Speed Sensor - If your Infiniti has developed a harsh shift or is stuck in emergency mode (limp mode), the vehicle speed sensor (VSS) may be the problem.. For example, your Infiniti may not shift at all or go in gear.. Rear-wheel drive Infiniti vehicles with 5 speed automatic (RE5R05A) transmission can have various shift issues, ranging from harsh and erratic shifts to failure to engage certain gears.. As the symptoms will be identical to those of a failed solenoid, checking both wiring and solenoid before replacing is recommended.. This will not happen during the 1st-3th gear shift, and in most cases, it will not trigger a check engine light.. The first step is to read fault codes from the transmission control module or what is known as the TCU.. The best way to reset Infiniti transmission is to use a diagnostic scanner to reset the Engine Control Unit and Transmission Module.. If your Infiniti transmission is not shifting properly, shifting late, or slips, the first thing you need to do is check the transmission fluid level.. Not all Infiniti vehicles have a transmission dipstick.

Common symptoms of clogged fuel injectors in Infiniti QX80 are slow acceleration, rough idling, irregular engine performance, increased fuel consumption, engine hesitation and misfiring.. Because Infiniti QX80 Gas pedal sensor additive is poured into the fuel tank and gets through the entire fuel system and the engine.. How to check Infiniti QX80 Gas pedal sensor head gasket is leaking in QX80?. Over time, dirt and grime that escapes through the air filter can accumulate in the throttle body, this results in improper throttle valve movement, which Infiniti QX80 Gas pedal sensor problems with the control of the air supply.. If the fuse is blown, replace it with a new one with the specified amp Infiniti QX80 Gas pedal sensor.. It does not matter Infiniti QX80 Gas pedal sensor which direction you insert the fuse..
