Has anyone else had their timing chain(s) replaced with the P0017 and P0018 code(s) and did it fix the issue? My 2007 AWD XE (40,000) miles had the P0017 and P0018 check engine codes come on and off for a week. I took it too the Saturn Auth Chevy dealer who stated it was a stretched timing chain that would have to be replaced and it will be in the shop the next 3-4 days.

Mine was throwing a CODE P0021 back in June of 2010 and they replaced the timing chain at that time.

In August, just my luck, they had to tear the engine down again and replaced the LH head and LH cam actuator. Without looking up the paperwork I cannot tell you what the codes that were being thrown the second time but probably the same as yours or heck could have just thrown another P0021 again.

Good luck.

Widely discussed on both the Acadia and Traverse forums. Once the chains are replaced; there hasn't been any issues.

An update the timing chain was replaced and all seemed fine with the Saturn Outlook until 3 days later when the service engine soon light came back on (and of course Lou Fusz Chevy couldn't get me an appointment any sooner than Feb 16 :angryfire Anyway the codes coming from the computer about 3 days ago where Heated Oxygen Sensor Control Circuit (bank 2 sensor 2) then P0161 02 Sensor Heater Circuit Malfuncion Bar 2 Sensor then P0056 (pd) H02S Heater Oxygen Sensor Control Cir bank 2 Sensor 2. Then today the "Service Air Bag" message popped up on the display along with the red airbag light.

This is what I'm concerned with, once the engine is dropped and the new chain in and then put all back together, all sorts of other stuff goes wrong because of being disturbed.

Yep....sounds like they didn't put something together right.

The quality of the technicians will determine how well the engine performs after it has been removed and reinstalled. I had my 07 engine dropped for the timing chain cover leak and it performs exactly the same as it did before it was removed

Had the timing chain replaced end of June 2010 and 45 days later had to have the engine dropped again for more work. Guess they got it right the second time because no problems since then. At least not with the engine.

Agreed and makes sense.

An update after it took a week to get another appointment from the Chevy dealer that swears :banghead: it never used to take that long to get an appointment until they got all this Saturn work and are just totally swamped (that they are going to move the neighboring Mitsubishi dealership they own next door down the street to the old Saturn dealership they owned (currently used cars only) and use that building for all the many oil changes/tire rotations/ minor stuff) they replaced the faulty oxygen sensor and so far no problems this week. They also attributed the brief air bag warning light stating an airbag was not working to the fact I had 2 cell phones and my laptop near the passenger seat and that interference has been known to cause a false positive reading on that light (ie if it happens again bring it back). So far its been a week and everything appears normal so I'm keeping my fingers crossed and knocking on all the wood and particle board around here. I do find it interesting the work order states some sort of "goodwill" code because the problem wasn't related to the timing chain but I got to think they messed it up working on the vehicle (as my usual mechanic stated the vehicle was fine last time they inspected it).
