Here is one more possibility for you guys.
The temperature gauge on your dash is fed from a different Coolant Temperature Sensor than what the computer uses to know when to turn on the fans, how fast to idle the engine, how rich to run the A/F ratio, and many other important decisions it has to make based on how hot the engine is running.
So its very possible that the sensor for the dash gauge has gotten covered in coolant 'sludge', corroded, or electrical problem with it. It may be showing much hotter than your engine is actually running.
You would need a scan tool to see what temperature the computer is seeing. It should be generally around 190-210 (generalizing here). If the computer shows normal temperature, but your gauge is showing hot, that's your culprit.
If you can find a local small-shop mechanic, he'd probably charge you very little to hook up the scan tool for 5 minutes when you have your RDV nice and hot so he can check engine coolant temp.
So - in summary - the needle should not hang out near the red zone, that's not normal. BUT it may be a problem with incorrect reporting of the temperature rather than an engine that is actually running hot.

'So - in summary - the needle should not hang out near the red zone, that's not normal'
Well it should not stay near red zone, but it is common for it to go near there when stuck stopped in traffic on a warm day, then go down to normal when moving at a better pace.

Hi, do you remember how you fixed the low tire pressure problem? I'm having the same problem...

I purchased a 2003 Ren last year and have put a lot of kms on it...had a few major repairs also. Just wondering if anyone out there is familiar with the error pictures that show up in the dash? I don't have an owner's manual to refer to and don't want to take it in if it's not necessary.

Hhmm since your putting on KMs, safe to assume you are in Canada? I believe the pictures (also assuming its a vous that was originaly in Canada) may be different then in the states. If you describe the pics (and color of background) it may help determine what they may be. If I can get a link to work, here is an online version of owners manual (its for 2007, but may not be much different)

Hi Amseidl, I would start by checking 2 things. The first is the "mass air flow sensor" and the second is catalytic converter. The mass air flow sensor can be faulty even if there is no code. Check several forums for "How to test mass air flow sensor" or talk to knowledgeable technicians. If your catalytic converter is clogged, you car will run poorly and continue to stall. Both items dealers often over look unless there is a code. If you are getting poor gas mileage, these 2 things can also be the problem. You can buy the mass air flow sensor at Auto Zone for $100 with core trade in. It is very easy and quick to replace. Hope this helps.

No, I do not "work for Buick." In fact, I do not work for any automotive company at all. I'm a corporate attorney. My wife drives a Nissan Murano and -- guess what -- I'm STILL driving my 2002 Buick Rendezvous. 96,000 miles on it as we speak.
I'm sorry your experience with your Buick was not as good as mine. But just because I haven't had as many problems as you -- you presume that I work for Buick?? Come on! I'm trying to give people my honest, truthful experience (MY experience) with my vehicle. I'm not saying that Buicks are problem-free. However, there is NO vehicle on the road today that is problem-free. Every manufacturer makes a few lemons. Mine, fortunately, was not one of them. Sorry if yours was.
We are definitely considering an Enclave in our future.
