Misfiring really bad

[SafetyPilotCal]

In all fairness.. lots of kinda shitty engines have wound up on Ward's 10 Best Engines list - the pre-2012 GM 3.6 which eats timing chain sets, the Nissan VQ with the same issue, the Subaru EJ with it's ringland failures, a Mazda Wankel of ALL things.. I do believe that the 3.3T Lambda II is a solid engine, given that there haven't been any failures we've seen until now, but I wouldn't go off anything Ward's says.

Additionally, they do NOT do any actual engineering-type testing; it's all subjective with NVH, fuel economy, performance, etc.

LMAO! The Nissan VQ is a “shitty engine”? GTFO.

The operative word was "kinda shitty". I've owned and put well over 100K miles on VQs. Yes, they ABSOLUTELY have their shortcomings, especially in transverse form. For YEARS you couldn't pull up next to a Nissan Quest or Maxima without hearing the timing chain slapping against the timing cover because the tensioners were dog shit and would snap in half or break off entirely. Happened to mine as well. Or who could forget the whole disintegrating precat debacle?

I mean I absolutely loved my Altima SE-R, but there were serious shortcomings with the powertrain in that car, including the 6-speed manual.

If it makes you happy, I'll call out another engine on the Ward's Top 10 list: the GM 3800. With all of it's intake manifold gasket issues that turn the oil into a milkshake. I've owned more than a few 3800 powered cars, including heavily modded ones, so I like them. But I'll admit when something has serious flaws. The VQ timing set and the 3800 intake manifold gaskets are two of them.

The timing chain issues occurred on one variant of the VQ family, and for a few years of that engine family's rather lenthy and illustrious lifespan. Most people who experienced this problem never saw catastrophic failure, just some extra noise from the engine bay.

It was a flaw that was corrected over a decade ago. I can't agree with your take on this matter. The VQ engine family is universally acclaimed, and my own experience does not correspond with yours.

I've owned 4 VQ-powered vehicles over the last decade with a total of over half a million miles between them, each on their original engine and with no major engine-related issues to speak of during their lifespans.
2000 Maxima VQ30 (close to 200,000 miles)
2013 Altima VQ35 (20,000 miles before trading in)
2004 Maxima VQ35 (over 240,000 miles)
2009 G37 VQ37 (over 120,000 miles before trading in)

Hi @Yemen

Any update on your engine problems, The cause of the problem and the solution?

The car was checked into the dealership sometime in March, I just got the car back last week. I'll post the service sheet so you can see what the problems and solutions were.

Hope your problems are a thing of the past. Glad to see you were taken care of.

Any issues with the warranty claim?

 

[Luc343]

Was this fixed under warranty?

Was this fixed under warranty?

Yes, after months of talking with Kia Consumer Affairs. They denied the warranty claim twice, but after some further diagnostics they found that the damage was caused by a defective part.

That's fair enough. If there is a defective part it should be fixed under warranty.

Any idea why they tried denying the claim?
