Mechanical problem with my car

I have an Infiniti Ex35 and I just drove about 180 miles and as I arrived at my destination my car started putting all of the sudden, meaning when I press on the gas it wouldnt go anywhere it would just putt like go for a second and pull back. I parked it about a block later and noticed my service engine soon light came on and my water gauge was on H. I tried to press on gas in park and it wouldnt rev up or do anything? I then checked my coolant and realized it was empty? What does all this mean? What could be wrong and what do I need to do?

My car has 143000 miles.

Experienced mechanics share their insights in answering this question :
Hello there, many different faults could cause your Infiniti EX35 to run poorly. With the coolant gauge reading hot and the lack of coolant it sounds like your car overheated. When cars overheat the computer will put them into a failsafe mode which prevents further damage but severely limits power and speed. There are many potential causes for the car to overheat, with the most common being the water pump, coolant leak, radiator, or radiator hoses. If you’d like to have this checked, a qualified technician, such as one from YourMechanic, will be able to diagnose the overheating and determine what is causing it.

How to Identify and Fix Common car Problems ?

The most common reasons an INFINITI EX35 is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
There are two main causes for engine overheat: The coolant does not flow through the system like it should. There is not enough air flowing through the radiator.
You want your Infiniti EX35 to last as long as possible. With the right maintenance at the right time, you could hit 200,000 miles (or beyond!) in your EX35. So, you want to care for your car, but you`re not sure when to get certain services.
The 2009 Infiniti EX35 is available with rear-wheel or all-wheel drive, but every model is powered by a 3.5-liter V6 attached to a five-speed automatic that includes manual shift control. Output is 297 hp and 253 pound-feet of torque.
That said, a severely overheating engine can cause the cylinder walls or the pistons themselves to warp, bend and deform. This will cause the perfect seal between the piston and the rest of the engine to lose integrity. Oil could be forced past the piston rings and into the engine, where it will burn the oil.
The INFINITI EX35 Reliability Rating is 4.0 out of 5.0, which ranks it 3rd out of 11 for luxury compact SUVs. The average annual repair cost is $588 which means it has average ownership costs. While repairs are more common, these issues are less likely to be severe than with other cars.
Are Infinitis reliable? Generally, yes, but some Infiniti models are more reliable than others. Overall, they tend to be known for having strong powertrains. Infinitis tend to get a good amount of positive feedback from their drivers and can last longer than the average car with the right maintenance.
The Award-Winning INFINITI 3.0 v6 Twin Turbo

For the second year in a row INFINITI`s 3.0-liter twin-turbo V6 engine has been named to the WARDS 10 Best Engines list.

The Q30 is built on the third-generation Mercedes-Benz A-Class platform to create a small, premium hatchback.
Wait until the gauge moves back to the normal range or the light extinguishes before you open the hood. DON`T wait for it to get better on its own. An overheating engine won`t repair itself, and you should bring your car in to Jiffy Lube as soon as you can.
Engines can overheat for many reasons. In general, it`s because something`s wrong within the cooling system and heat isn`t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
The most common reasons an INFINITI G35 is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Connect battery up to car, car then tries to start by its self without key in ignition. What can be problem
ANSWER : Hello, thanks for writing in about your Oldsmobile Aurora. A bad starter solenoid could make the starter run, but would not activate the ignition switch, so the engine could crank but not run on its own. I would recommend testing and/or replacing the starter solenoid. If you need assistance with fixing this issue, contact a certified technician, like one from YourMechanic, to diagnose the starting issue firsthand and help you make the necessary repairs.

Been having starting problems when car is cold thought it was starter motor. Now car sometimes does not accelerate when i hit gas
ANSWER : If you suspect the starter motor, I would never recommend replacing a part such as this from the junk yard. If the vehicle is starting fine now and acceleration is the only problem, it is possible that a trouble code may have been thrown to set a check engine light. I would recommend having the codes pulled by a qualified professional to aid in the diagnosis of this issue. Once any trouble codes are found, the technician will be more clear on what is causing this issue. Consider YourMechanic as a check engine light inspection can be performed at your home or office.

My car has a fuel injector problem, how can I free myself from this problem?
ANSWER : Hi there:

In most cases, the symptoms you’re describing are related to fuel delivery problems; with components such as the Mass Airflow Sensor, TPS (Throttle Position Sensor), or the throttle body itself being damaged, having faulty connections or simply being dirty and need to be cleaned. The only way to know for certain is to have a certified technician, like one from YourMechanic, complete a Check Engine Light inspection so they can download any stored error codes that might be an indicator of a problem that hasn’t showed up yet on the dashboard.

Can I drive my 2010 Infiniti Ex35 long distance if I was told that I need brake pads and rotors? I have to take a trip ASAP but I
ANSWER : It would be irresponsible for me to tell you your brakes are safe to drive on without looking at them. The problem is, when you need your brakes most, as in an emergency stop, that’s when you really stress them, so if they are marginal you could be in a lot of trouble in a panic stop situation. That said: the devil is in the details. If you were told you need pads and rotors by a workshop when they were doing routine service, it could be that there is as little as 0 or as much as 50% of the lining left because many shops have the policy of recommending pad replacement when the linings show more than 50% wear. If that’s the case, there could be several thousand miles of driving left. Check the work order and see if the tech wrote down the measured thickness of the lining somewhere. If it’s more than 1/8 inch, you can probably drive around OK for a few more weeks. If you can’t find out for sure, you can contact Your Mechanic to have a technician come over to your home or office to check out your brakes and make a recommendation.

ANSWER : Hi there – this behavior sounds like a throttle position sensor problem. Check first for any problem codes, whether the Check Engine light is on or not.
