What Are the Most Common Nissan Altima Complaints You Need to Know About?

If you own or intend to own a Nissan Altima someday, then here are a couple of complaints you need to take note of.

1. Engine Seal Failure

Owners of Nissan Altima have reported oil leaking from its car engine. This, in most cases, is caused by the cooler O-ring leaking oil.

This issue often occurs after changing the oil since the oil filter is attached to the cooler. Taking off and installing the filter now and then can reposition the seal.

This issue can be fixed by restoring the O-ring and in most times, the entire oil cooler.

If the oil leaking has been on for a long while, drivers are likely to get noise from the engine generated due to low oil pressure.

2. Fuel Pump Issues in Nissan Altima

Also, owners of Nissan Altima have revealed that some of the Nissan Altima models exhibit premature fuel pump failure. Indications or signs of this problem include shaking while driving, not starting, and hampering at slow speeds.

Nissan, however, issued a recall for model years affected (2001-2015, 1991, and 1993). Unfortunately, no recall was made for the 2019 Nissan Altima cars.

3. Failed Catalytic Converter

Another issue reported is the failure of the catalytic converter, which leads to the check engine flash coming on. The check engine light is forced to on when it occurs, which is not good as elements from the catalytic converter are likely to be drawn into the engine. This will often lead to serious damages. The repairs often amount to $2,185. Yes, it's that serious.

While 16 model years were involved, 1999 - 2015 Nissan models did not issue a recall.

4. The engine of the Car Runs Rough or Won't Even Start

Some of the Nissan Altima models experienced a couple of issues which had to do with the vehicle engine refusing to start and running roughly when it finally does. This problem began in 1993 and went on till 2008. Model years 2015 and even 2010 were also involved.

Owners complained that the vehicle starts up, hamper, and then refuses to start up again, or in some other cases, shut down and won't start again after a long drive.

Other owners revealed that the vehicle runs very rough, with the engine cranking. This issue is related to the leaking of the camshaft.

These are the major and most common complaints received from the use of Nissan Altima. However, you should note that all problems have been rectified in the 2020 Altima.

However, if you think or assume that your Nissan Altima is one of a recall or might be having one of the problems mentioned above, please do take it to a Nissan dealership with immediate effect.

Frequently Asked Questions (FAQs) About the Synthetic Engine Oil

How long does synthetic oil last?

Have you ever wondered why Nissan dealers constantly advise that you utilize the 5W-30 completely synthetic engine oil for your Nissan Altima? Here's why. Synthetic oil is constructed in such a way that it functions much better than traditional oil. One of such benefits is longevity. Synthetic oils come life span that is not found in most standard oil.

From research, most synthetic oils are still great even after 10000 miles. Synthetic oils can last this long even more because of the purer formula they feature, better than the standard oils. In other words, synthetic oils lack impurities, which allows them to handle the job more effectively, making the engine and oil last longer.

What oil filter brand does Nissan utilize?

You will need a new oil filter whenever you intend to change your synthetic oil after every 7000 miles or thereabout.

Nissan often produces their very own brand of oil filters. They usually come in the car. However, numerous oil filters from other brands work perfectly with Nissan cars, especially the Nissan Altima. Thus, it's okay if you want to go for those, or preferably you can acquire or buy the official Nissan filters. They can be found on Amazon.

What amount of oil does the Nissan Altima consume?

The engine size is the main factor when it comes to how much oil the Nissan Altima takes.

Most Nissan Altima's feature a 2.0-liter engine that uses about 4.7 liters worth of oil. However, the Nissan Altima premium trims come with a 2.5-liter engine. Thus, they require about 5.1 liters of engine oil to perform correctly.

Please note that in most cases, you will have to purchase more than one (1) unit of oil to get the exact amount you require to change your Nissan Altima's oil.

How often do I need to change my oil?

Always make sure to locate your owner's manual and ford to the car manufacturer's recommendations. Manufacturers are likely to void the warranty of the car's engine if the maintenance plan is not strictly adhered to, regardless of prolonged performance oils. Most engines do utilize oil even between oil modifications; thus, you must check your oil level using a dipstick from time to time. This exercise will enable you to regulate or oversee the oil color and level. Changing your oil is one way to avoid inexpensive repairs.

Is it possible to mix conventional or regular oil with synthetic oil?

Yes, but in bits. Conventional or regular oils are compatible with synthetic oils; thus, completing one with another when the corresponding one is unavailable is cool. However, regarding the additive variations of both oils, you should choose either the conventional or synthetic oil and hold on to it.

Blending conventional or regular oils with synthetic oils can also result in varnish and sludge over time.

What oil is best for high-mileage or older engines?

The formulations of high mileage of conventional, fully synthetic, and synthetic blend engine oils come with additives capable of conditioning seals, thus helping to fight sludge and prevent leaks.

As an engine becomes old, the piston rings and other internal elements or units seize up. Thus, unique detergent packages present in high-mileage oil blends play an important role in keeping the various components of the engine moving freely. This also lengthens the life and improves the oil flow of the engine.

How do I select the best engine oil for my vehicle?

Apart from the cost, fully synthetic oil defeats its other counterparts in terms of performance. It acts to reduce the number of irritants that come with regular oil changes and the resulting mud aggregation in the engine.

However, if the cost is a barrier, you can go for the blended option or, better still, revolve between the two options while you keep track of your vehicle's mileage.

Changing your car's oil type has no negative effect on the vehicle's engine. However, it is always the right thing to consult or refer to your manufacturer's manual. This will give you information on your oil's:

1. Oil specification.

2. Viscosity grade.

Is it okay to utilize another oil viscosity, different from the manufacturer's recommendations?

Never go against the recommended oil viscosity. Always ensure you strictly adhere to the recommendation made by the car's manufacturer. Going for an oil with a lighter weight compared to the manufacturer's specification will lead to failure in the heat-resistant function. Also, going for oil with a heavier weight than the one recommended by the manufacturer will overstress the internal engine components. Both can trigger serious and expensive repairs; thus, it's best to go for the engine oil recommended by the car's manufacturer for your usage and climate.

Are there any disadvantages of using synthetic oil?

The cost has been the greatest flaw of using synthetic oils. Not until automakers employed the usage of synthetic oil in producing new modern cars. The prices have since then fallen.

Synthetic oils are better than conventional oils because they retain their chemical properties and are better engine protectors.

However, the synthetic oil does not burn well when it gets to the convection chamber, which is likely to occur in older cars with worn piston rings or seals.

While synthetic oils do not degrade seals, they are thinner compared to their conventional counterpart. Because of this, they can easily pass through already existing worn leaks or seals, appearing to worsen the underlying issues.

Conclusion for Synthetic Engine Oil Buyers

When the time comes for you to replace or change your Nissan Altima's oil, make sure you go for the proper or perfect oil to keep your car's health in good shape.

Make sure you stick to a synthetic oil like the ones I mentioned under the product review section. It doesn't matter if you are getting the job done yourself at home or you are employing the help of a professional mechanic. These fully synthetic oils will make sure your Nissan Altima keeps running smoothly.
