Incorrect data can be sent by a malfunctioning or dirty sensor, which could cause the engine to get too much or too little gasoline. This may cause the engine to run poorly and sound louder than usual. Spark plugs that are bad or dirty might cause the engine to misfire, which will make the car run louder.
Most likely a simple exhaust leak. Any rust-through in the exhaust system, including the pipes, muffler, catalytic converter, and manifold, will modify the engine noise audibly.
around 110K. It freaks me out, but the car works just fine else. Have you ever found the
When accelerating, say up to 40 mph, I find the 2.5SL’s engine to be extremely LOUD. It’s a pretty pleasant ride once you’re in cruise, but the 4 cylinder simply sounds like it’s giving it everything it’s got. A 1,500 rpm rumble can also be heard from it.
The dealer drove after I protested, but they insisted it was normal? Although they updated the trans with the most recent “recall” patch, I haven’t detected a difference.
Do other 2.5sl owners observe the same thing, or am I simply not accustomed to the 4cylinder? We adore the Altima in every other way, but we now wish we had chosen the 3.5.
The engine noise in your new automobile is probably just a result of compulsive behavior; if you’re anything like me, you worry about things for a while after the fact. If that’s what you’re doing, I predict you’ll get used to it soon and won’t notice it as much.
The new 2.5 I4 in the 2013 is in fact quite noisy (“harsh” with some additional valvetrain noise) when revved hard with a heavy throttle, especially over 3000 rpm. The engine has to work very hard to get you to 60 mph in just 7.1 seconds. The V6 has a lot less noise than the I4 because the engine is not revving as high, is refined, and has a lot of torque. This torque is wonderful when the car is loaded because the V6 doesn’t bog down or struggle like the I4 does. The Altima’s V6 is only its most expensive model. Offering it makes sense for a number of reasons, with noise ranking highly. Despite this, the new Altima is a very quiet vehicle overall (road noise is effectively managed, there is little wind noise, and the new CVT is virtually silent in comparison to the previous model). The engine will therefore be the predominant noise you hear.
I’ve written additional posts on this site to discuss the V6 and how I tested it and the 2.5 before purchasing. I’m willing to confess that I have a prejudice in favor of the V6. The noise level of the newly redesigned I4 in the 2013 Altima, however, more than a little startled me. This assessment was based on my six-month rental experience of three 2012 Altimas with the I4 during the time that my Murano was being fixed. I therefore have a good understanding of the sound of the older engine and the pitch of its CVT. The new CVT is significantly more responsive and has a lot better sound quality (since it prevents the engine from revving excessively). However, both the older engine and the more recent engine (the 2.5) are quite noisy fours. They simply aren’t as refined and smooth as the Honda four (the engine from last year; I haven’t driven the current one). The Nissan 2.5 engine has always been known for being a decent performance and a good mileage engine, albeit it can be a little noisy at higher revs.
If you had a well-equipped car, such as the highly sought-after 2.5 SL model since they are selling so well, I think the dealer would be pleased to let you trade it in for a 3.5 model (perhaps without incurring too much of a loss to you). I suppose it wouldn’t hurt to inquire. But keep in mind what I said about compulsive behavior after the sale before you act on that advice. Just passing along.
Causes and solutions for the Nissan Altima’s high-speed buzzing noise
Humming while driving your Nissan Altima at motorway or freeway speeds can be risky in addition to being annoying. A humming noise is a sign that your Altima has an underlying issue that has to be fixed right away for your safety and comfort while driving.
Bad wheel bearings, uneven tire wear, and using tires with huge tread blocks are the most frequent reasons of humming noise in Nissan Altima at high speeds. Transmission failure is a less frequent reason.
When I accelerate, my Nissan Altima makes an increasingly loud noise:
The rolling components of your car need to be examined if, on the other hand, you notice that your Nissan Altima makes a louder noise when accelerating the faster you go. In reality, if this loud noise persists even after you fiddle with the engine, it is undoubtedly related to your gearbox and, more generally, your wheels. The condition of your bearings is the most frequent cause, so be sure to check them to make sure that is not the cause of the loud noise you hear while you accelerate. If not, click here to read this document on the Nissan Altima noise wheels.
Why is the whining sound coming from my Nissan Altima?
Low Transmission Fluid: Low transmission fluid is the main cause of whining when in gear for both manual and automatic transmissions. The internal parts of the transmission are improperly lubricated if the fluid level is too low. Friction between those pieces is what you’re hearing, and it can cause a great deal of harm. It is advisable to look for transmission fluid leaks if the fluid level is low.
As previously noted, some transmissions naturally whine, and this is quite acceptable. The whine may be more apparent in first gear, third gear, or another gear, depending on the make and type of the vehicle. Knowing the typical sound of your transmission is your best line of defense in this situation.
Flywheel or Clutch Wear: If you have a manual transmission, it’s possible that your flywheel or clutch needs to be resurfaced or that your clutch is worn out. It’s possible to hear whining, grinding, and other strange noises when these parts start to deteriorate.
If you hear the whining even while the clutch is not engaged, there’s a probability the throw out bearing is to blame. Instead of shifting into gear without applying any clutch pressure, noise from this bearing is more frequently heard while applying the clutch.
Bad input shaft bearing: When this internal bearing inside the transmission casing starts to fail, it might produce a whining sound.
Although each wheel hub contains a wheel bearing, a bad wheel bearing can cause a sound to travel and appear to originate from the transmission. Although a whine may be produced while driving, a failed wheel bearing is more likely to make a roaring sound.

A Nissan Altima—is it a sporty vehicle?
Our study has taken us through some fascinating areas of the debate over whether the Nissan Altima is a sports vehicle or something else. It implied to us that the answer to the question is a little more complicated than simple. So that you may fully comprehend each issue, we will walk you through it.
In terms of its basic characteristics and operations, the Nissan Altima’s first generation (1993–1997) is a tiny automobile. Later, many iterations of succeeding generations center on the small and mid-size automobile. A few characteristics including the exterior styling of various vehicles from the second generation onward hinted at sports cars. We cannot, however, categorically refer to them as sports cars.
Before we begin, it is important to realize that the phrase “sports car” is a generalization. A sports car is a two-person vehicle with a high-powered engine, quick handling, and high-speed operation. Consequently, an automobile that has the majority of the aforementioned characteristics is probably a sports car. We therefore attempt to compare the situation of previous Nissan Altima versions to key sports car attributes. While we wait, it’s important to remember that the Nissan Altima isn’t really a sports car.
How much does a Nissan Altima transmission replacement cost?
Cost of Nissan Altima transmission Depending on the car, a new Nissan Altima transmission could cost over $3,500, while less fancy transmission treatments like fluid changes and transmission fluid flushes can sometimes cost less than $150.
