I own an 06 Sonata with the 3.3. It is paid off and has 79,000 miles on it. I love this car.
It is fast, comfortable and I get about 20 miles per gallon around town and on long trips about 30. I have had a few engine issues and have done all the maintenance as required. It had the Harmonic Balancer replaced, Idle Pulley and sensor or two. The Hyundai Forums have folks cranking out 150,000 miles no problems with this car and others seeing it explode about 80,000.
I would love to hold onto this car a few more years. Any advice on this engine? Things to look out for?
Being a long time ex Ford Owner and loving to read your articles I trust your opinion a lot. I have owned a Mustang, Capri, EXP, Thunderbird, Excort ZX-2 and a Focus and other interesting vehicles in my torrid car past.
Ya know Dennis, its funny how those who fondly(?) recall Ford’s progressive product era (the 80s-90s) find joy in Hyundai’s modern offerings. And not just displaced Town Car fans eyeing an Equus, but you and…perhaps the 5.0L Easter Egg laying artist responsible for the photo above! OMG! OMG! OMG!
But I digress…
The Lambda V6 in your Sonata needs periodic valve lash adjustments. No timing belt worries and little else outside of proper upkeep, from what I see via Googling. I suspect those with grenaded Lambdas had such disappointment because of infrequent oil changes. If you minimize engine wear (i.e. synthetic oil and regular changes), valve lash adjustments aren’t in your future. You’ve likely reached the Sonata’s half-life: and not just because I’m a geek making a very
half-assed clever reference!
I suspect the motor will need a valve adjustment well before 200,000 miles, an awful painful punishment for your wallet. Especially compared to the Sonata’s street value. That’s when it’s time to sell.
Or get a junkyard motor with low miles and a warranty…or…and just hang on with me here…
If it’s okay to put a LSX in a Genesis, why the hell wouldn’t you put LS4-FTW in a Sonata? If you were crazy enough to own a Ford EXP, you know you gotta do it, to it…son!
