Although there are several issues with the Honda 1.5 turbo engine, it is still thought of as a dependable engine.
If the engine is properly maintained, these problems with the engine are not alarming. And by this, I mean that the head’s intake ports must be cleaned, as well as the engine, which needs to be walnut blasted.
Additionally, compared to other engines, spark plugs need to be changed more regularly. As a result of their design, these engines require more spark plug replacements than conventional engines. There are only four of them in all. So, for many automobile owners, replacing them won’t be a big deal. Even better, all you need to complete this task at home is a socket torque wrench.

Is the 1.5 liter turbo Honda engine dependable?
How dependable are the new Honda turbo engines? The new turbo engines from Honda are dependable, but not over the entire range. The 1.5 turbo is infamous for oil contamination and turbo failure, which has been documented to occur at only 40,000 miles. The other, larger engines are much stronger and more dependable.
Honda Accord 1.5 Turbo Engine Problems
One of the issues with the Honda 1.5 turbo engine is that it cannot heat up properly while idling. To put it another way, it takes longer for the engine to warm up sufficiently, which can be an issue for people who live in colder climates. Occasionally, it won’t generate enough heat until you begin moving. Condensation and too much gasoline vapor production are both possible effects of cold engines. The engine oil might easily become diluted by all of that extra fuel. Its direct-injection system also has a drawback in that the intake valves accumulate carbon. When coupled with that chilly engine, this is even worse.
Honda Civic 1.5 Turbo Engine Problems
The Civic experiences the same problems as the larger Accord, which has a higher tuned 1.5 turbo engine. The engine experiences fuel-oil dilution, which frequently happens in colder climes. The 1.5 turbo engine takes way too long to warm up because it is so efficient. When this happens, extra fuel vapors are not burnt, and they adhere to the cylinder walls. Following that, the oil picks up on it and dilutes it. Then, two additional significant problems are added to the oil dilution problem. First off, there is a significant amount of carbon buildup on the intake ports. Additionally, the spark plugs might easily become fouled.
Honda 1.5 Turbo Engine Problems
The good news is that by 2021 and 2022, most issues with the Honda 1.5 turbo engine had been resolved. The main problem with the 1.5 turbo engines was oil dilution, which on its own led to other problems. This is mostly because the 1.5 turbo engine takes a while to warm up, especially in cooler weather. Honda only made a minor adjustment to the ECU to fix this. As a result, the 1.5 turbo engine could start out slightly richer. Additionally, Honda helped the engine warm up by directing some of the heat from the passenger compartment there.
How Long Do Hondas Last
One of the world’s toughest and most resilient automobiles is the Honda. They should easily be able to reliably go between 200,000 and 300,000 miles. This could be increased even more with careful maintenance and servicing. In other situations, owners have relied on their Hondas for up to 20 years with little problems compared to the majority of other vehicles.
Did Honda Fix The Oil Dilution Problem For 2021
Sadly, this problem still exists in 2021 despite a software modification to assist Honda’s engines heat up more (which is the primary source of oil dilution). In particular, oil dilution still affects the 1.5 turbocharged Earth Dreams engines in 2021 and 2022. Owners may only prevent severe dilution by changing their motor oil more frequently in the first place. Some owners advise changing the oil as soon as every 3,000 miles.
How long does a 1.5-liter Honda engine last?
Is the 1.5T Honda engine dependable? Yes, the engine is often rather dependable. Regarding dependability, we’ll give the Honda 1.5 Turbo above ordinary feedback. Time will tell how they perform over the long term because the engine is still relatively new. There are a few typical issues with the 1.5T engine, but they aren’t anything too serious. However, excessive oil dilution should be avoided since it can shorten the lifespan of the 1.5 Turbo. Apart from that, the Honda 1.5T is a strong, dependable engine.

- Depending on the model, torque output can range from 162 lb-ft to 177 lb-ft, which is excellent.
- Additionally, for a continuous burst of acceleration, that torque peak starts low and continues to be strong for a long period as the revs increase.
Which Honda engines have issues with oil dilution?
One of Honda’s best-selling car models is the CR-V, which also held the top spot in terms of popularity for a number of years. However, due to an alleged flaw in its Earth Dreams 1.5L direct injection engines, recent model year Honda CR-V automobiles reportedly experience oil dilution.
A class action complaint claims that Honda’s 1.5L Earth Dreams engines have gasoline-diluting engine oil, which can lead to issues including stalling and power loss while driving.
Owners of 2019–2021 Honda CR-V vehicles filed complaints with the National Highway Traffic Safety Administration alleging engine damage, stalling, fuel mixing with oil, and stalling. Below, you may see a list of some of these issues, along with earlier complaints from Honda Accord and Honda Civic customers.
Does Honda still have an issue with oil dilution?
Currently under investigation by Migliaccio & Rathod LLP are the 2019–2022 Honda CR-V, Civic, Accord, and several other vehicles.
The 2019–2022 Honda CR–V, Civic, Accord, and specific Acura models equipped with the 1.5L turbocharged engine are under investigation by Migliaccio & Rathod LLP for possible fuel dilution problems. Particularly, owners complain that gasoline and engine oil mix, causing the oil level to rise and the vehicle’s ability to lubricate to decline. Owners claim that oil diluting still occurs despite a software update that was intended to fix the problem. For some, the car’s interior smells like gasoline, while for others, the acceleration is lost, and for yet others, the steering is affected. Because owners have reported feeling loss of acceleration while driving, this problem puts Honda and Acura owners at risk for both premature engine wear and accidents. Owners claim that while Honda dealerships admitted this was a problem with the 2017–2018 model years, they thought it had been resolved for the model years 2019 and onward. In order to remedy the fuel dilution issue, Honda has not issued a recall.

Which Honda engine, the 2.4 or 1.5 Turbo, is superior?
Although the 2.4L inline-four engine is marginally more efficient and accelerates more quickly, the 1.5L turbo engine has reliability issues that have damaged Honda’s image.
In contrast, the 2.4L inline-four is a tried-and-true engine with a superb dependability record that, with routine maintenance, should last well over 100,000 miles. The 2.4L is the greatest option despite being only offered in the less expensive LX model due to its dependability and affordable running expenses.
What model year Hondas have issues with oil dilution?
Owners claim that the engine oil in their 2019–2021 CR–V, Civic, and 2018–2021 Accord models has fuel contamination. It is a process where fuel leaks into engine oil as it moves towards the crankcase and is also referred to as crankcase dilution. Although every engine goes through this process, severe fuel leakage causes the engine to wear down far more quickly. Oil dilution in the Honda 1.5L turbo engine causes the oil level to rise, engine bearing failure, and failure of other internal engine parts. A catastrophic engine failure or even stalling while driving could happen as a result of this.
Additionally, owners claim that when they take their cars to Honda for repairs, they are informed that the degree of engine oil dilution is acceptable. They are consequently refused warranty coverage and are compelled to pay for repairs out of pocket.
How durable are turbocharged engines?
Despite the fact that certain turbocharged engines are dependable, turbo engines frequently have additional issues. A normally aspirated (non-turbo) engine has fewer parts than a turbocharged engine. These include an intercooler, boost control system, vacuum pump, exhaust wastegate configuration, and a more intricate crankcase ventilation system (PCV). Failure of the turbocharger itself is not unusual. More things can go wrong the more parts there are.
Higher combustion chamber pressure causes higher crankcase pressure when the cylinder walls and piston rings deteriorate with increased mileage. This may lead to oil leaks that appear in numerous locations and are challenging to rectify.
Having said that, many turbo engines have a lengthy lifespan. Consider the Mark IV Volkswagen Golf / Jetta’s turbodiesel (from the early 2000s). With proper maintenance, many of them are operating well into 200K miles. Learn more about engine maintenance.
Hondas or Toyotas have a longer lifespan?
Toyota triumphs thanks to better ratings all across and a more adaptable lineup. Honda automobiles do, however, have some advantages, particularly in the SUV market. In the hybrid and plug-in car categories, Honda and Toyota are almost equally competitive. But what advantages does each brand’s owner receive?
Benefits of Owning a Honda
Speed is one area where Honda outperforms Toyota, particularly in sedans like the well-liked Civic and Accord. The quickest vehicle in the lineup even though it isn’t a true sports car is the Civic Type R. It has a 306-horsepower turbo-four-cylinder engine that can reach 60 mph from 0 in less than five seconds.
Honda aspires to be the best in the SUV market, and the CR-V is a fantastic compact SUV because of its effective drivetrain, spacious interior, and upmarket cabin.
Where Honda Lags Behind
The midsize Honda Ridgeline vehicle outperformed the Toyota Tacoma and had a respectable towing capability. However, Honda doesn’t sell full-size trucks. The Toyota Tundra, a rival, can pull 8,000 more pounds than the Ridgeline.
Honda automobiles additionally lack cutting-edge infotainment options like smartphone connectivity. Although this maker doesn’t scrimp on safety features, a mid-sized touchscreen and smartphone connectivity cost extra. The controls are also a source of frustration for some customers.
