Each car engine has its advantages and disadvantages, as well as the Dodge Ram 5.7 problems that many vehicle owners often discuss.
This article will discuss in detail the various issues of the Hemi 5.7 engine that are important for you to know.
Is the 5.7-liter Hemi Engine In the Dodge Ram Dependable?
An extensive amount of high-kilometer outfitted Hemi V8 trucks are available for purchase.
Although no engine is entirely free of faults, the group of powertrains known as the Hemi is typically quite dependable.
For instance, the 5.7 Hemi engine has existed for nearly two decades.
The Hemi tick is perhaps one of the most significant Dodge Ram 5.7 problems, and it occurs due to a lifter-bearing malfunction.
But this is not a seriously destructive problem. Although it is rather prevalent in models with more significant usage, its repair is reasonably affordable.
However, the Hemi units used in Hellcats, which one might think to have the highest risk of breaking down, have still achieved over 100k miles without suffering significant breakdowns.
There is a recall for cars manufactured in the year 2017 Hellcat due to the possibility of a lubricating oil hose being disconnected.
But, this issue is limited only to the 2017 version period. It has been resolved on the more significant part of vehicles manufactured in the same year.
Ultimately, purchasing a car with a Hemi engine is an entirely reliable judgment.
Still, you want to get a comprehensive service chronology and use an online VIN lookup resource to investigate the car’s history before making any purchases.
The 5.7L Hemi powertrain seen in Dodge cars is widely regarded as among the company’s most successful engine designs.
Following the introduction into manufacturing in 2003, these motors have undergone just a single significant redesign, which took place in 2009.
It has also served as the foundation for engines installed in various Dodge, Chrysler, and even Jeep cars during their production history.
As you maintain it properly, powerful engines can survive more than 300k miles.
But they use higher fuel compared to various types of engines.
It is public knowledge that they require more fuel frequently. Despite this, their durability makes them an excellent choice.
Whether you’re shopping for an automobile or pickup, something you’re considering has its 5.7-liter Hemi powertrain.
Now Hemi 5.7 is an excellent option for you to consider.
Hemi 5.7-liter engines are known for their dependability.
If there is a need for repairs, engines are simple in design.
Plus, you have an abundant supply of replacement spares for them because vast numbers of Hemi are in use today.
In general, the 5.7-liter HEMI is a powerful and dependable powertrain.
It is safe to say that this engine is not among the most dependable available.
In addition, it is far more dependable than the other options.
There is a solid reason certain brand vehicles have been equipped with the Chrysler 5.7L engine for almost twenty years.
Consumers take pleasure in using this trustworthy engine.
Issues may occur, but you shouldn’t judge the engine based on such situations.
Every engine has unique qualities, but high-performance units tend to have more issues than their less powerful rivals.
The problems with the camshafts are by far the most problematic on the checklist, even though they are probably exaggerated.
It is a significant issue that has to be taken into account.
Are there any issues with the 5.7-liter Hemi’s performance?
The following are some problems that often occur with the Dodge Ram 5.7-liter engine.
Dodge Ram 5.7 Problems: Hemi Tick
There is a possible link between the Hemi tick and the frequent issues.
I am adopting a general perspective regarding the concerns with the 5.7-liter engine ticking.
A conversation regarding ticking mostly on 345 HEMI is an exciting topic for a few different aspects.
Several people believe that the ticking is perfectly natural and that it should not impact the functionality or durability of the Hemi engines.
But, some 5.7L HEMI users have reported that engine ticks also required them to replace the entire powertrain.
Here are some more typical probable reasons for the 5.7 HEMI ticking you need to know.
- A problem with the exhaust manifold’s bolts
- Lifters that don’t work properly
- Lifter roller stuck in the up position.
Here, we’re mainly concerned with faulty lifters, including stuck lifter rollers.
It appears to be the most prevalent and significant source of the Chrysler 345 HEMI engine ticking issue.
In 2009 or later models, this problem is more prevalent, leaving many people to suspect that the multi-displacement technology is responsible. So, yes, that’s a great thing.
A lack of oil supply towards the lifter rollers is believed to be the root cause of the problem.
The ticking tone is caused by the lifter contacting the camshaft blades.
Due to the metal vs. metal collision, scratches form in the lubricant.
Many particles can be collected in your oil filters when discovered in time to avoid significant harm.
Significant engine damages can follow if the problem is ignored for an extended period.
On top of that, the 5.7 HEMI camshaft should eventually need to be replaced.
Even if you use refurbished components and services, the task might be almost as expensive as buying a new engine.
It is a significant problem. But, the online world loves to exaggerate the scale of most big engine failures, which is undoubtedly the case here.
Lifter Roller Problems with the Hemi 5.7 Engine
When a lifter roller fails, the following are some warning signs to keep an eye out for:
- Warning light for the engine
- Engine ticking
- Engine misfires
Sadly, abnormalities with the lifter rollers with the 5.7L Hemi are incredibly challenging to identify.
Many people only hear the ticking noises and have no other indicators.
When the issues are serious enough or if they are ignored for much too prolonged, though, you can have misfires or see a check engine illumination on your dashboard.
If you’ve had a stroke of bad timing and have this malfunction, it will probably happen somewhere above 100k miles.
Despite this, the issue might occasionally present itself while the warranties still cover the engine for the first 60k miles.
Dodge Ram 5.7 Problems with the exhaust manifold’s bolts
Damaged exhaust manifold bolts are probably the most typical issue with the 5.7L HEMI engine. We may be honest to say that this is the most prevalent issue.
There have been reports of people experiencing difficulties more than once.
Most of the time, the bolt on the back passenger side manifold was the first to break.
Numerous people believe this is the section of the motor and manifolds with the highest temperature, so they think the back bolts fail earliest.
The assumption would be because the manifold reshapes in the rear position, which ultimately causes the bolts to break.
Mostly on 5.7 HEMI, this problem is somewhat excluded from other issues.
However, another important topic of discussion takes us closer to something like the tick of the engine.
It could be that a damaged manifold attachment bolt causes particular ticks from 345 Hemi engines.
The ticking sound I covered before has a distinct breakdown spot than this one.
If, on the other hand, the engine in the Dodge 5.7 is ticking, inspect your exhaust manifold bolts before doing anything else.
Fixing this issue is often considerably simpler but less expensive since it is among the relatively frequent Dodge Ram 5.7 problems.
It is still an issue, even though it is not very significant.
The ticking sound is the most obvious sign that one or more bolts holding the exhaust manifold together have failed.
Damaged manifold bolts cause a leakage in the exhaust system, mostly found on Hemi 345. In extreme cases, you will experience a lack of power.
Early problems must be repaired free of charge by the car dealer, as many appear to malfunction throughout the warranty term.
Alternatively, customers may have to pay for the repairs personally.
The do-it-yourself community may easily access the manifold.
However, bolt removal may need some skill based on the actual breakdown case of the bolt.
It is highly recommended that you change each of these bolts when working in that area.
The cost of the components might be close to one hundred dollars.
To avoid bending, some people choose to install any non-OEM exhaust manifold.
But when the manifold is deformed, it will end up causing early breakdowns of new bolts.
That’s the case even though the manifold has been replaced.
MDS (Multi-Displacement System) Problems in Dodge Ram 5.7
I will go quickly over this conversation and the misfires following up shortly.
During traveling at highway speeds, the 5.7 liter Eagle Hemi was updated in 2009 and later used multi-displacement innovation to remove four of its engine’s cylinders.
We know that is an excellent method for reducing emissions while saving money on gasoline.
At first glance, it does not appear to be anything problematic with MDS.
If you prefer it, the power from having a high displacement of 5.7 liters remains available.
But on the other hand, if you choose not to, the engine will operate more fuel-economic. Far more favorable for anyone who is not interested!
Yet, there have been reports of buyers being unhappy with the MDS for the 345 Hemi.
It looks like the system is prone to having specific periods in which the engine’s running will not sense as it should.
The potential impact of cylinder deactivation on the lifetime of 5.7 HEMI engines is another bone of disagreement.
Since this tech is developing, perhaps the future may show its success.
It has been speculated that the multi-displacement mechanism may be primarily responsible for the problems with the lifter rollers.
The combustion of fuel generates energy.
However, the engine will operate at a lower temperature whenever specific cylinders are cut off.
Metal will get damaged if the temperature is allowed to fluctuate continuously.
When the 5.7 engine deactivates cylinders, it’s been the equivalent of four cylinders.
Questions about lifespan are reasonable to have in light of this fact. However, I would rather not be more specific because this subject has many complexities.
There are no problems that may be connected to the MDS.
But, there seem to be technical principles that show that MDS may well create a critical consequence on the lifetime.
Spark plugs have a greater risk of fouling when the temperature is excessively low.
Oil would never be effective if the cylinders were still at an insufficiently low temperature. The list of potential outcomes is rather extensive.
The last observation is that a 5.7 liter Hemi MDS would be an excellent idea.
But, there seem to be several grey areas, and it may require some time till we get conclusive explanations.
Therefore, it must not be a significant problem right from the get. Yet, it is essential to think about it.
It is not entirely accurate to refer to misfires as a widespread issue.
Most of the time, misfires are brought on by additional problems, such as lifter roller faults.
As a result, within these scenarios, it is better understood as a sign rather than an issue.
Nevertheless, regular maintenance components have the potential also to create malfunctions.
The spark plugs for the 5.7-liter HEMI engine are the primary topic of this section.
It has a total of sixteen spark plugs. It provides plenty of leeways for misfires since the spark plugs are so old and rusted.
Furthermore, many other factors can also cause malfunctioning ignition systems like ignition coils, malfunctioning injectors, and other mechanical problems such as lifter rollers.
Nevertheless, spark plugs remain a fundamental component of vehicle care that become prone to being neglected.
Sometimes, we fail to recall that the spark plugs have been slightly older than you had previously thought.
Sixteen spark plugs seem to be a considerable amount.
It just needs a single spark plug to run out prematurely or miss to place a misfire for the entire system to be compromised.
Mostly on 5.7 Hemi, spark plug malfunctions are pretty uncommon.
Nonetheless, you recommended still replacing them after 30k-40k miles.
Spark plugs are an essential component of regular maintenance, which, if neglected, may lead to inconveniencing problems such as misfires.
The 345 HEMI’s dependability depends on various factors.
A few of the areas that we have a direct influence on is the maintenance.
Be sure to do routine maintenance on your 5.7 liters Hemi, including changing the oil at the recommended intervals.
If that isn’t the case, then a portion of it is merely determined by pure chance.
You have many additional things to keep in mind, such as how long hours you push your engine, the circumstances in which it performs, and so on.
One more time, the Chrysler 5.7 Hemi is a reasonably dependable engine.
There will be issues with dealing with the engine’s lifetime.
But, this is a concern that you accept with every engine, and the most you can do is maintain it as effectively as you can.
The 5.7L HEMI engine should last more than 200k miles when adequately cared for.
Especially with carefully serviced HEMIs, many users still report unfortunate or random situations.
What model year was the 5.7-liter Hemi that had problems?
If you’re in the market for something like a car but desire significant extra power under your hood, you might choose to search for a Dodge Ram with the renowned 5.7L V8 Hemi engine.
A powerful engine, which you can find in various Dodge vehicles like the RAM, Dodge Durango, and Dodge Challenger, is prepared to accept ones driving enjoyment to a great level.
Nevertheless, what are some of the most often documented difficulties with the Dodge Ram 5.7 Hemi that you need to be aware of before purchasing one?
Dodge Ram 2011-2013
There have been many reports of owners of 2011-2013 Dodge RAMs complaining of unexplained ticking noise. It occurs even though the vehicles are being driven.
Some 2011 RAM 1500 owners have reported hearing the ticking noise that may result from damaged manifold bolts throughout the engine.
The engine might have produced a ticking sound if such an exhaust manifold had been damaged somehow.
But, reports indicate that the issue persisted through the modifications people had made.
Dodge Durango 2007
The Hemi powertrain optionally offered in the 2007 Durango has become the subject of many customer problems.
Most of such issues have to deal with the engine unit stalling out suddenly.
If the engine stops working, the vehicle will also lack stability control and brakes, increasing the likelihood of being involved in an accident.
The problem is mentioned in other complaints as well.
It involves a person who says that the owner of a 2007 Dodge Durango must change the engine to keep the vehicle functioning.
In addition, another person’s 2007 Durango experienced problems with the power scheme and its engine.
Dodge Magnum 2005
It has been claimed by several customers of the 2005 Dodge Magnum that the 5.7L Hemi of the vehicle often stalls after being refueled, and this problem exists each time the car is given a full load of gas.
The engine stalls out shortly after starting up after being refueled. It continues to do so many times afterward.
Because the driver loses control of the car once the engine dies, the owners believe that something like this threatens public safety.
Could the Dodge 5.7 be a wise choice for an engine?
A strong argument can be made that the Chrysler Hemi engine family is the most well-known engine type on the planet.
Hemi engines were installed in some of the finest recognizable automobiles of the 1960s and 1970s, including:
- Plymouth Superbird
- Hemi Cuda
- Jensen Interceptor, etc.
The 5.7-liter version has unquestionably left its impression on the automobile market. First, however, this section aims to determine whether or not it is a great engine.
There could be some doubt over the dependability of the 5.7 Hemi.
Although some of its buyers have driven it for over 300k miles without a problem, someone else has reported severe issues during the early 100k miles of ownership.
You should not anticipate over 200k miles out of a 5.7 Hemi if you avoid the extensive fixes to keep it running for as long as it takes, especially considering the typical durability of the Ram vehicles in which it is mounted.
Although many positive points could be stated concerning the Hemi V8, one could argue that the appearance seems outdated since it was first introduced.
Among the most significant negatives of a 5.7 Hemi is its poor fuel economy, which is much worse than the EPA estimates claim it to be.
A fresh Ram 1500 equipped with 5.7 Hemi would achieve 15 mpg in the city. However, on the highway, it will reach 22 mpg.
The numbers don’t add up in the real world, particularly when they’re fully loaded or pushed to their limits.
The fact that the 5.7L Hemi has been produced for 19 years and has a substantial percentage of happy customers is evidence that it is an excellent engine. It is possible that it will travel beyond 200k miles without experiencing any issues provided that it does not suffer any of the problems that we have described.
In general, how long does a 5.7 Hemi engine typically last?
When choosing a new vehicle, the expected length of the engine’s lifespan should be a primary consideration.
Those interested in buying a truck and those who already own one frequently ask about engine durability before it gives out.
It is a reasonable question to ask for several self-evident factors, like the automobile’s extended lifespan, which is excellent.
I will give you some details of the average lifespan of the 5.7 Hemi motor.
In addition, it examines the maximum amount of distance that can be driven on the 5.7 Hemi engines, as well as the variables that might shorten their lifespan.
The 5.7-liter Hemi engine has a maximum possible lifespan of 250,000-300,000 miles.
It is reasonable to anticipate that the engine’s functionality will gradually decrease when it has accumulated around 250k miles of usage.
But, the lifetime of the 5.7-liter Hemi engine will also be impacted by various circumstances, which may trigger a slightly earlier drop in its power before it has reached the full lifecycle of 250k miles.
Below are some examples of such influences:
- Surfaces that are particularly difficult to traverse
- A lack of regular maintenance
- Challenging conditions brought on by the environment
Because of its reliability, several automakers have begun to produce engines based on the same concepts and layouts.
Which model year of the 5.7-liter Hemi is considered the most desirable?
If you’ve been planning on installing a new 5.7L HEMI V-8 into an earlier Mopar, I have some advice.
Engines like this are continually improving to enhance power and reduce fuel consumption. However, several changes were needed to the 2008 5.7 Hemi V-8.
5.7L V8 engines were workhorses between 2003 to 2008, powering everything, including Ram pickup, Durango, Charger R/T, and plenty more.
The engine proved its value in terms of capability.
The 5.7-liter HEMI V8 engine, in its 2nd gen, was included in Ward’s prestigious and desirable 2009 10 Best Engines category.
There were several significant inner adjustments, including improved technologies in 2009, that made it worthy of such awards, like:
- overhaul of the engine compartment
- building improvements to the crankshaft
- effectively inlet and exhaust points
- reworked combustion room architecture for enhanced compression
- optimized valve-spring configuration
- excellent camshaft type
- expanded oil pump capacity.
The adoption of VCT significantly increases the engine’s gas mileage and horsepower beyond the previous 5.7L HEMI V8 models.
So, to achieve the best possible cylinder combustion, the VCT technology adjusts the timing of valve releasing processes.
VCT is a system that alters the timings of the engine’s camshafts while it runs to optimize performance and cost-effectiveness.
A broad torque gradient with low-end pulling strength seems to be the result, but the leading edge maintains everything of that HEMI performance.
MDS innovation was employed in the 2009-latest 5.7L HEMI V8 engines. However, it was enhanced by previous generations.
Conclusion of Dodge Ram 5.7 Problems
Some problems with the Dodge Ram 5.7 engine are the Hemi tick, lifter roller issue, broken exhaust manifold bolts, Multi-Displacement System issue, and misfires.
Of course, no engine is perfect, but the 5.7 L HEMI is still a reliable engine. So if you want your car engine to last, you must do regular maintenance properly.
