Toyota has a system where they use both port injection and GDI to prevent carbon buildup on the intake valves. Of course this makes for more complexity, but port injection is a very mature and reliable technology. (Not sure about Honda.)

As others have said, stay away from Hyundai/Kia products which, among other things, are prone to fires and are currently the object of a class-action lawsuit due to excessive oil burning in cars they have sold over the last 10 years. (They've gone considerably downhill since your 2003 Sonata was made.)

I agree with the comments made.  I will only add that the advantage of going with a Toyota engine is that - with the exception of one engine - all others have a dual setup consisting of port injection and GDI (Chuck mentioned this), but the vast majority of the Honda engines have GDI only.  Also, some of the Honda engines still use timing belts which has to be changed out periodically (whereas the Toyotas use timing chains and can go much longer).  Moreover, the V6 Honda engines have cylinder deactivation (VCM) which can lead to potential issues down the line.  Finally, more of the Honda engines are turbocharged than the Toyota ones (many of Toyota’s are still naturally aspirated which will outlast a turbocharged engine).

Between Toyota and Honda, while their engines in general are both still better than the rest of the competition (in North America), I would much rather go with the Toyota engines esp. if you plan to keep for a long time:  you don’t have to worry about carbon buildup (since you have port injection to mitigate that) nor changing timing belts (since they have timing chains which can last the life of the vehicle), and don’t have to worry about potential cylinder deactivation issues in the future, and there’s more opportunities to get a naturally aspirated engine.

Of course, if you prefer performance and vehicle dynamics then you’ll go with Honda (although some of the newer Toyotas are no slouch), but for pure reliability and less maintenance items over time you’ll go with the Toyota.

Either get the Toyota or one of the Hondas and choose which one you like most. DO NOT GET A Hyundai 

Why get a Honda or Toyota instead of Hyundai? Read the link below:

I usually prefer Honda over Toyota, because of everything else Honda does with their cars in terms of look and feel, and performance. 

The latest generation of Honda engines has me frustrated with the GDI, turbos, cylinder deactivation. I get why they are doing it. They have to meet strict fleet fuel and emissions requirements by government. 

Toyota can get away without doing these things, because they have a large fleet portfolio of hybrids, which helps meet the strict fleet requirements. 

I still would get Honda in heartbeat, it just takes a little more effort to figure out which engines will have better projected reliability. 

And I wouldn’t shy away from Toyota either. They make amazing cars. 

hyundai, meh. 

Thank you.  I saw that newer engines use the port and direct injection...  port for lower speeds and hwy the direct.  Thanks for the comments.  Greatly appreciated.  Because the pricing does not seem to vary much, Toyota or Honda.  I do have a 2008 MDX (honda) and love it and a 2006 Sedona with over 222k miles.  No issues.  Sigh.  🙂  I have friends who have Corolla SE and love them.  Thanks!!!
