#2207 of 2541 Air bag warning light, BCM & SDM
Feb 13, 2010 (9:33 am)
A 2003 Rendezvous air bag warning light has been staying ON at random times after starting the vehicle. A Buick dealer read several DCTs and said the BCM and SDM were not communicating with each other and that the BCM was most likely the problem. (NOTE: None of the other systems or components controlled by the BCM were giving any trouble.) The BCM was replaced and the date on the original was noted as 1-31-03.
The dealer then found that when the vehicle was cold from sitting in the parking lot, the light would stay ON. When the vehicle was brought into the shop and allowed to warm up, the light would stay OFF. The dealer noew says the problem is in the SDM. The mechanic told the owner (my daughter) that all the wiring harness were inspected and voltages were tested with the SDM unplugged from the wiring harness. No problems were found. He said he could not test for voltages and resistance with the harness connected. (I use quilting pins to reach into a plug or socket and get resistance readings with power OFF and voltages with power ON)
1. Should the dealer be able to test and isolate the problem with a module, wiring harness/connectors or sensors without trial replacement of modules ($500 + for BCM & $700+ for SDM)?
2. Can the SDM (mounted under the driver's seat) be tested for temperature sensitivity by cycling from warm to cold with an ice pack and heat lamp?
3. Has anyone had this temperature related problem before?

I wouldn't wish a 2003 Rendeveous on my worst enemy. I bought new 6 yrs ago. Has 66800 miles and the problems have been from day 1. Air wouldn't work first time went to use 4 months after purchase. They had to replace brake pads just a few months after buying. Vent louvers weren't working on the rear console. Did lousy job putting console back and had to take back for them to redo it right. Extreme noise from tires - fineally replaced with Michelins (my cost) and it solved noise. Had engine knocking (ticiting). Flushed and said something most have got past filter. At 51000 window regulator broke, at 60000 and second regulator broke. Wouldn't even talk about a discount to fix. Wanted almost 700 to fix both. Now it's leaking coolant - intake gasket. Looking at another 500+ dollars. This car has been a joke -- paid over 33000 for it. Could've had TWO Kia Sonrentos for this piece of crap. I told Dealership my first and last Buick. As far as I was concerned GM could fold. I took it else where to get the window fixed - cheaper. I'll know tomorrow if they are going to help on the engine job - although I'm not betting on it. STAY away from the 02 , 03 04 models at least. Don't know about the newer ones.

Early ones are problematic. If you are very handy around cars, or you get a warranty, fine, otherwise I would stay away from 2004 or earlier.
Our 2007 has 38000 miles on it now and has been flawless. Drives beautifully, tons of room, quiet, good gas mileage. We love it and I wouldn't trade it for anything else out there. Our friends have a 2006 and they feel the same way.
Every brand has lemons, foreign and domestic, its important to do your research before buying. So you're one step ahead of everyone else buying blindly!

I have a 2005 and I love it. Mine has captain chairs in the middle with a 2 seat bench in the back with cup holders between the back two seats. I love the fact that the back folds down anytime I basically need a truck type feature. I simply keep one of those waterproof blankets in the back storage compartment and I have a way to instantly haul things like mulch or wet soccer stuff instantly without getting my car a mess. I love all the fancy features of the backup system. I have only had to have some work to the front wheel area which was about $500 and replaced the fuel filter for about $50 and a new battery. I have about 70,000 on mine. Still love it and would definitely buy another one.

I have a 2006 Rendezvous CX with 75000 miles on it. I bought it brand new 4+ years ago. I have had one problem with it. The right front wheel bearing went at about 65k miles. Replaced it myself for less than $100. Other than oil/filter changes every 5k and new tires I have done nothing to it. More reliable than a Toyota. Been a great vehicle for our family.
#2212 of 2541 Buick RDV 2005 problem
Feb 24, 2010 (3:27 pm)
I purchased the car last 2008 then i was having too much problems 1st the tank keeps on going up and down. 2nd my steering wheel is shaking sometimes but not too often 3rd the car is having a hard time accelerating but when you reverse the car it feels smooth but when you go forward the car feels like its on a foot break and when i came out it smells like burning tire but there is no smoke at all

1. Sounds like a fuel sender. The tank will need to be lowered and the part replaced,
2. Probably a tire balance issue, but could be warped rotors as well if it mainly happens when you're applying the brakes.
3. Possibly one of your brakes is binding. Whoever did the last break job may not have properly lubricated the caliper slide points and now the brakes have overheated, warped the rotors, and fried the pads.
Sounds like the last owner (or his shop) didn't do proper maintenance. Get those brakes checked out and you'll be back to enjoying the ride.

I dispise my 05 Rendezvous now. I loved it for awhile but I have put 8 yes 8 wheel bearings on it. My trunk opens whenever it wants. It sounds like a freight train. AWD leaking AWD disable. I just had it at the shop yesterday to replace a wheel bearing again. My car alarm goes off whenever when it's hot out it never wants to start. Brake Warning. Squeeks and Rattles. Speedomiter quit one day when i was 200 miles from home and I had to drive home without a speedomiter luckily I had verizon's excellent GPS which helped somewhat. Liftgate is SO HEAVY! Shocks went bad, power window on right side stopped, Transmission Surges when going uphill, CD player skips, Liftgate stopped opening, Vehicle Service Soon comes on when it is below 30 degrees farenheit. I have had so manyn problems I expected better from a BUICK next week we'll be getting either a ford escape or chrysler pacifica.

NO IT IS NOT!!!!!!
After having so many problems with it, I made up in my mind to trade it off. I was confronted by several car dealerships about this thing, known for transmission going out (had my replaced last year) known for to many minor problems, but costly fixes, and most of all known for the motor locking up (thats why I don't own one now). Still owing on it, an spending more money to fix it then the note itself. I surrendered it back to its owner, gladly.
I have brought many lemons in my life time, this lemon was the only one that presented itself as a lime....then a trash bag. I too thought more of Buick then this. Next time (To: Buick Inc.) stop trying to be like the next man and just be the better man.... This was the worst invention you have ever made.... A ticking time bomb....

I have a 2002 Rendezvous with about 167,000 miles on it, bought new in 2001. It's had more than its share of problems. I too have the temperature sensitive airbag sensor light issue. The dealer is about to replace the SDM module for about $800.00. I'm hoping that fixes it. This is the last expense though for this car. Any more and it gets recycled. (still rides good though}.
By the way. I just put Continental tires on and it's like driving a whole new car. Very good handling.
