Fuel economy by cdyoung

My 05 AWD RDV is a great vehicle with deteriorating fuel economy. With less then 22K on the car the fuel economy seems to get worse with every tank. I have the 3.6 ltr and was getting near 18 when it was broken in and now get around 14, what's up? I really enjoy the car and don't share the misery most of the people who post have.

Does anyone know where the fuel filter is loacated on the 3.6 ltr engine. I searched under the car during my last oil change and couldn't find it. I have an 05 RDV Ultra

Not sure where the filter is on the vous, I have heard its sorta near the drivers seat (underneath vehicle of course) in the Pontiac version, but haven't been there nmyself yet. Just follow the fuel lines from the tank until you find it. (BTW you do have to be careful not to get an eyeful if you do change it, have something ready to catch what comes out of it). For the milage thing, it may jsut be winter fuel and colder temps (depending on where you are), my vehicles are dropping now also.

Brian,
   It was the 2002-2003 RDV's that had most of the bad problems.The 2004-2007 RDV's were much better.Our 2002 CXL AWD was roomy and rode and handled great.However,it was underpowered and the reliability wasnt there.
 
   If anyone is buying a used 2002-2003 Rendezvous from a dealer,please call the former owners to see why they traded it off.Theres far too many problem ones out there.They had numerous problems such as BCM's,AC Condensors,Intake And Head Gaskets,Wheel Bearings,Stalling And Refusing To Restart,and much more if you got the wrong one.I've seen some 2002's have up to a dozen different problems.
 
  I wish you well with your 07 RDV.

I just found this post. My 02 Rendezvous is doing exactly the same thing except that since I don't have AWD my traction control and ABS lights periodically flash on. Several days ago my car woudn't start and seemed like a weak battery. After 12 hours coming home form work I tried starting again and it started with exhibiting any problem or apparent battery weakness. This am I tired starting again and I heard a "click and all lights and power including dome and headlights died. The batt is 2 years old, the alternator , plugs and cables are 2 months old. I know someone stated that it couldn't be a BCM but I am at a loss and don't have the money to take it to the dealer. Any help would be apprecieated. Thanks , PK

Sounds like it may be battery cable connection problem. I had a similar problem with my Pontiac version. Check my post #34 in Pontiac Aztek starting issues topic.
 
For the TC/ABS lights , I would fix the other problem first and see if its still an issue, anything electrical could potentialy be affected by weak current

We are also more or less happy owners. We bought our 2003 Rendezvous from a dealer in Sept w/73,000 miles. We didn't find this website until after the purchase and we were both very worried. HOWEVER, we used what we read on this site and knew what to look for. We did have to replace the BCM unit shortly after purchasing but my husband ordered the part straight from Buick, ordered a BCM unit for a 2007 Rendevous and we haven't had a lick of problems since. We need to have the back up sensors cleaned so they work properly. We immediately (after reading this site) had the transmission fluid completely changed out to the "better stuff" - whatever that means to a women! LOL - and replaced one ABS sensor (about 120 bucks).
 
For the price we paid for the car and the repairs that we did , we are still under book value for the car. I love the way it drives. Gas mileage isn't bad. Comfortable for kids. No extra room when seating more than 4 but what crossover does?
 
We are aware of it's problems, but for real, research ANY car/make/model and you find just as much if not more......
 
We are happy

loss of control and shutdown message by swimswan

I slipped on the ice and hit a parked trailer with my '05, and I was able to drive away, didn't relize the damage until later as it was dark, but after driving about 7 miles on an icy highway, I got an error message that came up that my vechicle was "shutting down" and I lost total control and it went off into the ditch and hit hard. Has anyone ever had there car shut down like that?? I am just glad I didn't get too hurt, but also my airbags did not go off at all when I hit the ditch hard.

You hit a trailer? What kind of trailer?
 
I've been in frontal accidents before. To get past the front bumper, grills, etc. takes a very strong impact. You couldn't have done all that damage and not realized you had damaged your car, even if it was dark. If it was dark, how did you drive, since your headlights would have been destroyed??
 
But until you break through the bumper etc., you aren't getting to anything engine related that would make the car turn off.
 
Now if you DID break through all that, your air bags would have gone off when you hit the trailer.
 
If you had broken the radiator, you would have gotten a low coolant message WAY before any disasters engine shutdown. Further, I've been a GM man for life and have never heard of this "shutting down" message. Where did it display this?
 
Finally when any engine shuts off, you still retain some braking ability and the steering wouldn't lock.
 
Care to share some more details and explain what really happened?

thanks for your interest. I hit a tow truck trailer that was parked on the wrong side of the road when I slipped on the ice and it hit the corner of the vehicle and my left headlight was damaged. The grill and the body of my car looked fine, but the underneath of the bumber got destroyed when I hit the ditch 6-7 miles later on the highway when my car totally shut down. I could see because the right headlight was ok. It was a hard corner impact to my car...but I really don't know why the shutdown message came up in the center of the dash where all the other messages come up. I was totally shook up and driving very slow after I hit that trailer and was just trying to keep on the road as it was extremely icy. Can the body shop where I had it towed be able to check any computer messages that came up on the vehicle?
