Ever wondered what the most reliable Japanese vehicles of the last decade are (2011–2020 model year)? Well, we are here to tell you just that. It may or may not be surprising that this list is dominated by Toyota, well-recognized as the most reliable car brand in the world. Yet, domination is not strong enough of a word, because every single vehicle on this list is a Toyota product, or uses Toyota's expertise, especially considering Lexus is nothing but Toyota's luxury brand.
You might be thinking this is propaganda, but our research validates this data. We have taken into account every Japanese vehicle produced between the 2011-2020 model years. We then found every model within those years with the highest overall J.D. Power Reliability Score. Here's the list.

Here's What Could Affect Toyota's Legendary Reliability
While Toyota has been the king of reliability for decades, find out what could dethrone the Japanese brand from the top spot
In compiling this article, we have cross-referenced information for vehicle reliability, maintenance, and pricing from sources like J.D. Power, Kelley Blue Book, Edmunds, RepairPal, CarEdge, and Consumer Reports to give you the most up-to-date and accurate information possible. Please note that we have ranked the following models from the least reliable to the most.
10 2011 Toyota Avalon
Reliability Score: 87/100
The Buick of Japanese sedans, the 2011 Toyota Avalon, is a standout performer. The 2011 model year received a facelift and is the last production year of the third-generation Avalon. With exceptional marks in every category, the 2011 Avalon is the quintessential full-sized sedan.
Reliability
With updated styling and tech, this final model year is without a doubt the most refined package of this Avalon generation. Combined with one of Toyota's claims to fame, the 2GR-FE 3.5-liter V-6 engine, you have a validated recipe for success.
The 2GR-FE is one of the most notable engines in Toyota's history. It has served as the powerplant of choice for over 10 different Toyota models over almost two decades. The 2GR-FE 3.5-liter V-6 engine is nearly bulletproof and is one of the primary examples of Toyota's exceptional engine reliability.
9 2011 Lexus GS 350
Reliability Score: 87/100
The 2011 Lexus GS 350 is everything you could want from the 2011 Toyota Avalon, but just nicer in every way. A plush ride, smooth engine, and rock-solid quality make the 2011 GS 350 the best and last model year of the third-generation Lexus GS.
Reliability
Much of the 2011 Lexus GS 350's reliability comes down to the 2GR-FSE 3.5-liter V-6 that powers it. The previous 2GR iteration, the FE, served as a rock-solid foundation for the FSE variant to build upon. The FSE variant is a beefed-up version of the same engine found in the Avalon. The FSE makes both more power and is more efficient than its predecessor, in no small part thanks to its improved fuel system. When new, the FSE variant consistently topped the best engine lists. Now, over two decades since its debut, its reliability has only been solidified.
8 2013 Lexus GS 350
Reliability Score: 87/100
The 2013 Lexus GS 350 is a rare vehicle for how solid it is despite being only the second model year of a new generation. The general rule of thumb is that later model years tend to be the most refined. Yet, the 2013 fourth-generation GS 350 proves as reliable as its renowned predecessors off the bat.
Reliability
This continued success is thanks to the carryover between generations of the 3.5-liter 2GR-FSE engine. Yet, this FSE variant is an improved iteration of one found in the previous generation. If you are looking for as bulletproof of a V-6 as possible, this 2GR-FSE must be on your shortlist.

Reliability
The third-generation RX 350 marks the last use of the standard-setting 3.5-liter 2GR-FE engine for the Lexus RX. We first discussed this variant in the 2011 Toyota Avalon and there is a reason Toyota used this specific engine with critical acclaim for well over a decade.
6 2020 Lexus RX 350
Reliability Score: 87/100
Most vehicles across segments in the 2020 model year suffered from inconsistent reliability. The 2020 Lexus RX 350 is one of the few exceptions. The 2020 RX 350 is the most modern vehicle on our list and the only one found within this current decade. Just when you thought that Toyota couldn't make the 2GR V-6 platform more efficient, they did.
Reliability
The 2023 RX 350 continues the legacy of reliability of the 3.5-liter 2GR V-6 family. Found in the 2020 RX 350 is the 2GR-FKS variant, which provides even better economy and efficiency than previous 2GR variants. This variant debuted in 2015 and is still available on new Lexus 350 models today.
5 2014 Toyota Camry
Reliability Score: 88/100
An absolute symbol of reliability is the Toyota Camry. The 2014 seventh-generation Camry may be among the most reliable Camry models ever.
Reliability
Featuring the same 3.5-liter 2GR-FE (in V6 models) found in the 2011 Lexus RX 350 and 2011 Toyota Avalon, the 2014 Camry guarantees reliability. With an even lower entry price point than either of those models, the 2014 Camry provides amazing value per dollar. The 2014 Camry also offers the first inline-four engine on our list in the 2.5-liter 2AR-FE. This inline-four is found in all Base, LE, and SE model trims within the seventh-generation Camry.
The 2AR-FE served as the platform for many mid-sized Toyota models from 2008 and on. Beginning in the 2017 model year, the 2AR would be replaced by the A25A-FKS engine platform, which still currently powers the current generation Camry.

4 2014 Scion FR-S
Reliability Score: 88/100
The 2014 Scion FR-S is the only true sports car on our list. Any sports car that is on a list concerning reliability means it is special.
Reliability
The 4U-GSE 2.0-liter boxer engine powering the first-generation FR-S is the only engine on this list that is not a full Toyota product. Known as the FA20D in its Subaru-based designation, this particular variant would be discontinued in 2021 with the introduction of the second-generation Toyota GR 86.
Despite the fact this engine has its known quirks, in its segment it is still a staple of reliability compared to some of its competition. Prospective owners would still be wise to familiarize themselves with this platform. Yes, it's a Toyota, but this is still not a true Toyota engine. Having a solid understanding of the maintenance history beforehand can alleviate common pitfalls and expensive mistakes associated with these engines.
Discussion
If you were looking for a budget friendly, reliable ride, would you buy a vehicle from this list?
There are many reliable cars on the market, thankfully. But Toyota products still seem to maintain an edge, being ever so slightly ahead of its competitors. Would you venture out of the 'obvious' choice for reliability and pick a car from another brand, or not?
3 2011 Lexus IS 250
Reliability Score: 88/100
Rounding up the top three of our list is the 2011 Lexus IS 250. The 2011 model year was the second refresh for the second-generation Lexus IS line.
Reliability
The first Lexus 250 model on our list means this sporty sedan is powered by the 4GR-FSE 2.5-liter V-6 engine. The 4GR is a detuned variant of the renowned 2GR-FSE we have discussed at length. With a significant power output reduction compared to 350 models, this allows for an overall increase in reliability.
2 2017 Lexus ES 350
Reliability Score: 89/100
Our number two spot belongs to none other than the 2017 Lexus ES 350. This luxury mid-sized sedan is one of the greatest balances of luxury and value. The 2017 facelift model is the last model year of the sixth-generation ES.
Reliability
To no surprise, you will find the 2GR-FE 3.5-liter V-6 gracing the engine bay of the 2017 Lexus ES 350. There is a reason Toyota never changed this engine in over a decade of ES 350 models. It's that solid.

1 2011 Lexus LS 460
Reliability Score: 89/100
Who would have thought that the most reliable vehicle on our list features a 4.6-liter V-8 engine? Yet, it is safe to assume the facelifted 2011 Lexus LS 460 offers one of the most luxurious and reliable experiences any car could give you.
Reliability
The 4.6-liter 1UR-FSE V-8 engine debuted in the third-generation LS 460. With the LS line being the Lexus' flagship model, there are little to no expenses spared for the LS 460. The previous generation UZ V-8 platform was solid, but slow and inefficient compared to the 1UR. Thanks to its direct injection system, the FSE variant is much improved, especially in performance.
It is no wonder why Lexus used the 1UR-FSE for over a decade to power the LS 460 to reliability stardom. The UR platform is still in use today to power performance-focused Lexus models across their entire vehicle line-up.
