Alex Betancourt, a year ago you said the problem was inside my engine's computer, which was under warranty, so I took it back to the dealership. They said they have no idea what's wrong and recommended selling the car for scrap. Did you check the key itself?

Apparently if the car is fine and the key isn't coded correctly to the engine's computer, the car won't start. This problem started while I was driving, so it may not be the key… but since no one can tell me exactly what the problem is, it could still be the key!!
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. I have forwarded your inquiry to our sales and service department, so they can look up your individual appointment and access the mechanics remarks and inspections completed. However, if you had an issue where the car shut off while driving and does not currently start today, it is rather unlikely that the problem is an incorrectly coded key. A key will fall out of programming typically if there is an electrical short in the ignition system, a battery was replaced and the battery terminals were connected wrong or the key’s battery is dead. Again, I will have our CS department contact you to determine if the key was checked during this inspection.

How to Identify and Fix Common car Problems ?

What problems does a Nissan Maxima have? Late-model Nissan Maximas have problems with leaking low-pressure air conditioning connections, failing ignition coils leading to check engine lights, and power steering pump leaks. However, very few of the Maxima`s problems are catastrophic.
The most common reasons a Nissan Maxima won`t start are a dead battery, an alternator problem, or failed starter.
Transmission issues: Owners of 2004-2006 Maxima sedans complained about slipping and overheating automatic transmissions. This particular issue may lead to a destroyed transmission with symptoms such as rough shifting, poor acceleration, and hesitations between gears.
Nissans are usually very reliable, lasting up to 300,000 miles and 20 years with excellent maintenance. The Nissan Maxima may be the most reliable model of all.
DETROIT (AP) — Nissan is recalling more than 809,000 small SUVs in the U.S. and Canada because a key problem can cause the ignition to shut off while they`re being driven. The recall covers certain Rogues from the 2014 through 2020 model years, as well as Rogue Sports from 2017 through 2022.
The majority of common Nissan problems are transmission-related issues. However, you should still keep an eye out for other typical Nissan troubles, such as engine failure, faulty interior components, and malfunctions in the steering system. can expect their cars to last for years.
Some other typical reasons engines fail to start include:

Low or discharged battery. Corroded or loose battery cables. Starter motor relay failure. Ignition switch failure.

The Years To Avoid For The Nissan Maxima

The biggest year models to avoid are in the 2004-2006 range due to transmission failure. Any model made between 1995 and 2013 is bound to have mechanical problems as well. For those who love the sporty appeal of the Maxima, the models made from 2009 to 2014 are not ideal.

2016 is considered the best year Nissan Maxima. This model has received the highest overall safety ratings in all tests conducted by a federal testing agency. The car is also packed with modern features and comes in five trim levels to suit your needs. It is also priced reasonably for its class.
The Nissan Maxima will be discontinued in 2022 as part of Nissan`s ongoing plans to focus on a more-fuel efficient lineup of vehicles. The final Maxima will arrive in late 2022, with the last model being built in December of that year. In its prime, the Maxima was a very competitive model.
Engine issues make up roughly 18% of all Nissan owner complaints . The majority of the issues have been reported by Altima owners.
In general, Nissans are known for being very reliable cars that are easy and inexpensive to fix. But some Nissan vehicles are going to be more reliable than others. A few models fall below the desired standard you would probably want in your next car.
Nissan maintenance costs are much more affordable than the industry average. Drivers pay an average of $500 per year for scheduled maintenance and unscheduled repairs. Having an extended car warranty may reduce overall ownership costs by paying for repairs after the Nissan factory warranty expires.
The Nissan model that is the most reliable and ranks the highest in its vehicle category is the Nissan LEAF, which ranks 2 out of 15 Most Reliable Small Electric Cars. Following the LEAF is the Nissan Frontier and the Nissan Maxima. You can see the rest of the Nissan vehicles and their rankings below.
Over the years, Nissan has become a renowned brand because of its high reliability, outstanding safety ratings, and innovative designs. The automaker`s reputation for making solid, affordable cars is as strong as it was during its early days.
If, however, it`s just the Nissan key fob battery that requires replacement, you may still be able to start your Nissan even with a dead key fob battery: If your Nissan car, truck, or SUV has a key fob port, just put the fob in the port and tap the brake pedal or clutch as you press the START/STOP button.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
A Bad Crankshaft Position Sensor

The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.

The Maxima puts out an impressive 300 horsepower, which makes acceleration seem to happen almost instantly. Most sedans that reach these higher horsepower numbers do so with the use of forced induction in the engine.
The Maxima is equipped with a 3.5L naturally aspirated engine that is mated with a CVT. The fullsize sedan takes only 5.7 seconds for a 0-60 acceleration and has a top speed of 135 MPH.
In terms of performance, the 2020 Maxima is slightly more powerful. It has a larger engine capable of 112-HP more than the comparable Altima.
The Maxima SR includes most features of the SV trim level, plus: Sport-tuned suspension with re-tuned dampers, stiffer springs, and larger front stabilizer bar. Paddle shifters. Dual-panel panoramic moonroof with one-touch open/close.
The Maxima started out as a top-of-the-line Bluebird. The PU11 (first-generation model) was launched on October 17, 1984. With the first model change (J30) on October 21, 1988, however, it was recognized as an independent series.
The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.

Alex Betancourt, a year ago you said the problem was inside my engine’s computer, which was under warranty. Did you check the key?
ANSWER : Hi there. I have forwarded your inquiry to our sales and service department, so they can look up your individual appointment and access the mechanics remarks and inspections completed. However, if you had an issue where the car shut off while driving and does not currently start today, it is rather unlikely that the problem is an incorrectly coded key.

p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?
ANSWER : The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you. If you follow through with a repair with us you will be reimbursed for the cost of inspection.

2007 Honda Odyssey, 102K miles. Started hearing some engine noise when turning steering wheel at low speed couple of weeks ago. En
ANSWER : The noise associated with steering at low speed is not related to the fault causing code P1717 to display. The steering related noise could involve the power steering pump and/or drive belt although there are other possibilities. To pinpoint the source of the noise you are hearing, the recommended service is a power steering system inspection.

With regard to code P1717, that code sets if there is a problem involving the transmission selector range switch. Among the possible faults is a faulty transmission range switch, the transmission range switch harness is open or shorted and/or the transmission range switch circuit has high resistance electrical connections. To resolve that issue, the appropriate service is a check engine light diagnostic – code P1717. During such a diagnostic, a certified mechanic from YourMechanic would retrieve all the diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are tested to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

car will not start/ starter checked out good had ecm changed1 1/2 years ago check engine soon light came on the next day wouldnt
ANSWER : If the Check Engine Light is on, I recommend that you request a check engine light diagnostic. That diagnostic will very likely lead to a resolution of your no start condition. If the starter motor is, in fact, good (stater motors have to be tested under load, by the way; freewheel bench tests are unreliable), but there is no noise, that is the starter motor is not turning, that means there is a fault in the starter circuit, which circuit starts at the battery, runs through wiring, relays, fuses, the ignition key and to the starter solenoid. That circuit would have to be traced to find the fault. If, on the other hand, the starter is turning over the engine at sufficient RPM, but the engine doesn’t run, that means there is an ignition or fuel system fault, or a problem with a key global sensor such as the engine coolant temperature sensor (or other sensor, such as crankshaft position sensor, etc.). In any event, if you schedule a check engine light diagnostic, a certified mechanic will be dispatched and he or she will get this promptly resolved for you.

I am not getting any power when I turn the key to the on position. there is no dash lights only check engine lite comes on.
ANSWER : The problem of having erratic electrical issues with this year Bronco they have problems with the ignition switch losing contact. You should check and replace the ignition switch. When the switch is removed you should check linkage rod and electrical connector for problems and repair as needed along with replace the ignition switch.

Hi! Check Engine Light appeared after upgrading the timing on my Cadillac SRX 3.6 engine from year 2004 to 2007.
ANSWER : Hello. I would not recommend changing the timing between model years. There are certainly software differences in the engine management system (this is what is causing your Check Engine Light), and there may be physical differences in timing reference points (both camshaft and crankshaft), sensors, etc. If you changed the cam timing physically, you may also be in danger of a valve-to-piston collision as well – which would cause major damage to your engine. Best to stick with the stock timing for the "build year" of your engine. If the problem persists, consider having the Check Engine Light diagnosed by one of our mobile technicians.

Car won’t start, check engine light is out but other lights are on, got new control and immobilizer but the problem remains.
ANSWER : Hi, thanks for writing in. It is possible that your check engine light bulb could be out. I would recommend having a qualified professional remove your instrument cluster to determine if the bulb for the check engine light has failed. If the bulb has failed, I would recommend having it replaced and see if your results change. If the bulb is not faulty, it is possible that something was installed incorrectly during the most recent repair. I would recommend retracing your steps to determine if any steps were skipped over or done improperly. This will help to determine the cause of why the check engine light will not work. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect your electrical system for you, and make or suggest any repairs as needed.

Check Engine light on. Would the computer give all error codes in one shot? How do we know the engine’s condition?
ANSWER : Hi there. From the description you have provided, I’m am inclined to agree with your assessment of a used engine being installed in your vehicle. An inspection of the engine, by a qualified technician could determine whether the engine is sound. The Check Engine Light on and having a TPS (throttle position sensor) code does not necessarily mean the sensor is at fault. Circuit tests should be performed to confirm the fault. The likelihood of the ECM (electronic control module/computer) giving you all the codes at once is remote. Other component failures could occur. Address those as they come up. Even though you already made the purchase, I recommend having your vehicle inspected by a certified technician so that you can get a thorough evaluation of the car’s true condition.
