My 2007 XL7 currently has 80 000 KMS or approx. 50 000 miles. My engine light came on a few weeks ago but would only come on for a short time then go off for a period of time. I checked the code and it came up as a P008, something to do with the crank or cam shaft timing. But since the light was not staying on permanently I thought it might just be a problem with the sensor itself. About 2 weeks later the light came on and stayed on. The truck seemed to be running fine and have not noticed any lack of performance. I brought it to the Suzuki dealer this morning to find out that the timing chains need to be changed. I was told that this is a problem/flaw with these motors. The parts have been ordered and my vehicle will be spending 2-3 days next week. This is all covered under the powertrain warranty. I did ask if I should expect the same problem 80 000 KMS later and they said probably not since they are replacing the parts with what is suppose to better quality parts from Suzuki. I am not impressed at all with this problem and I will probably get rid of this vehicle by next year. I have lost confidence with this vehicle!

I've never heard of a P008 code. :huh:

What or how did they determine that you need chains?? If your engine was properly maintained and treated, that's bunk! :eek:

I've got 243,000 miles on mine.

timing chain

The code is a DTC P0008 "Engine Position System Performance Bank 1".There are actually 3 timing chains. This code activates if there is a misalignment at an idler sprocket for either bank or at the crankshaft. I believe this problem is only on 2007 and newer XL7's. Apparently there is so much tension on these chains that they do actually stretch which will eventually cause problems so I am told. I will update more when I bring the vehicle in next week. I will ask more questions to find out more about this.

Yup. They stretch.. I've replaced tons of them. Some less than 40,000 km
If you put the old ones next to the new ones you can actually see about 1/2" difference.
I've seen one get bad enough to skip a tooth!

What year and model do you have and where are you located (US, Can, UK, or?) :huh:

This source states, in part...

Suzuki builds the High Feature V6 at its Sagara, Japan plant for the Suzuki XL7 SUV under license from General Motors. Displacing 3.6 L, this engine produces 252 hp (188 kW) at 6500 rpm and 243 lb·ft (329 N·m) at 2300 rpm. Fuel economy 4–6 km/liter in city, 7–9 km/liter.

Applications:

* 2007-2009 Suzuki XL7


Reading the whole article, this engine has FAR reaching success in a myriad of other vehicle applications. How and why are the Suzuki derived engines so frail in the "chain" world , Larry? :eek:

i dont know how many other vehicles this actual engine made it into..
i DO know that there has been a couple cases of the chains needing replacement on the Pontiac Torrent.
Equinox, which was on the same platform never had the 3.6
they got a 3.4 version (so i am told)

i see that.. but i dont think they are identical.
here's what suzuki has to say
this is from a training course..

Introduction
Although the architecture for this engine begins with a General Motors North Star design, the N36A has
been redesigned from the cylinder heads on up by Suzuki engineers for application in XL7. The entire
engine is manufactured in Japan, including casting of the cylinder block. The engines are then shipped to
CAMI for installation in XL7. This engine is unique to XL7 and is not shared with any General Motors
products that are assembled at CAMI.
Key features to will be covered in detail in this reference book include:
• Engine mechanical configuration
• Camshaft timing
• THROTTLE ACTUATOR CONTROL system (drive by wire)
• Variable valve timing (VVT) for intake and exhaust valves

It appears that you're one of the "lucky" Zuki modded GM 3.6 guys then. :(

But at 14.5 hrs each they keep me busy
So...out of warranty, we're looking at a maybe $1500 ish w/parts, out of pocket repair? :huh:

easily..if you go with tensioners too, the parts come to around $1000
there are also a few special tools needed for doing the job..

Hi, I'm a VW mechanic - done lots of belts, chains and cam tensioners, never a Suzuki. About to start my friends 2007 XL-7. Any advice before I start? Thanks! Any reply would be appreciated.
