#50 of 59 Occasionally cranks but does not start
Apr 09, 2012 (4:12 pm)
We have a 2003 Buick Rendezvous with 140k miles on it. The car runs well; however, we occasionally face a problem with the car. This issue generally occurs after driving on warm days (mostly hot days 80F +). If we stop somewhere and wants to restart the car, it cranks but does not start. Once the car sits for 25-60 minutes, it will start. There are no codes when this occurs and the dealer cannot seem to find a problem without a code. the issue has begun 4 years ago and now is getting more frequent. Any help is appreciated.

This sounds like 'hot' start problem that happens when vehicle is shut off for only a few minutes, then fails to fire up on restart. The only solution I know of is to hold key in start position for longer until it fires, for me the more times you try it, the harder it is to start, so the second attempt I hold it start position quite a while.
#52 of 59 2006 Buick Rendezvous Difficult to Start
Apr 18, 2012 (6:03 am)
Appx. 2 years ago the RDV began to be hard to start. Turned over ok but would stumble and act like it's starting but dies after letting off the starter switch. Happened after the car was warm and was intermittent. Has steadily gotten worse but I finally found the problem. I remembered a throttle body problem with another vehicle so looked at the RDV's and there was significant buildup on the backside of the throttle plate. Cleaned it by holding the valve open & wiping the backside with a rag soaked in carb cleaner. Did this about a month ago and haven't had a problem since.

This exact issue is happening to me as well. My 2003 Rendezvous has 130k miles and has been doing this for over a year. It only seems to happen when its hot out; in the winter I do not notice a problem. Even the 25-60 minute time frame is the same. Is this a known or common issue? Any chance someone knows exactly what this is and what to do about it?
#54 of 59 07 Rendezvous Starts/stalls
Sep 28, 2012 (8:12 am)
I have been reading all the posts but have only seen one the resembles my problem with no solution that i can find. My car often, not all the time but often, will not stay running when started. It seems to start but then stalls right away. I have to give it a little gas to keep it started. This is not happening during any paticular time either, hot or cold. Nor has it stalled while moving. Please help.

A couple simple things you could try are a new fuel filter and air cleaner if they haven't been changed in a while, other things might get more complicated.

Good afternoon martinae,
Do you happen to know if/when you had spark plugs and wires replaced on your Rendezvous? While this is not an official GM diagnosis, I hope it's helpful as you gather information. If you decide to work with a dealership on getting your starting concern looked into, please let us know by emailing us at socialmediagm.com (include your name and Edmunds username, contact information, and the last 8 digits of your VIN).
Sarah, GM Customer Service

Couple things here to try. 1 - take a look at your mass air flow sensor, its just after the air filter, but if it was an issue your check engine light should be on. 2. Clean your throttle body, which is above the mass flow sensor. I would 1st try using a can of "Sea Foam", in the gas tank, this will help clean up any deposits on both of the above.
ps: Just a note, the gas pedal in todays cars only opens the throttle body to increase air to the fuel being supplied by the electric fuel pump. The days of a gas pedel are gone as we know it. Hope this helps

I have just recently started having problems with my Rendezvous not turning over. A friend told my husband and I to tap on the fuel pump, and the vehicle will start. The first time we tried this it worked. No problem until now. We are having the same problem, and the tapping did not work this time. My spark plugs have been changed. The wiring harness has been replaced, even-though; the idiot who replaced it knew he was cheating us. I am going to try getting the fuel filter replaced to see if this is the problem. Until then, anyone who has a solution, please let me know. The Rendezvous acts if it is going to start when the key is turned over but never catches to start. Is this problem related to any recall?

Hhmm, Does it not turn over (nothing when key is out in start position) or does it turn over but fail to 'fire up' and run?
If it does turn over does the problem happen at any time (when engine is cold or warm) or does it happen only after engine has been warmed up?
