#1 of 37 02 Rendezvous Temperature Problems
Feb 24, 2008 (9:14 am)
I recently bought an 02' Buick Rendezvous and immediately had to get the Manifold gaskets changed. A couple days after I picked up the car, I noticed the Temperature gauge fluctuating. On The freeway, the temp gauge would stay around the 1/4 mark, but when stopped on city roads or at lights, the gauge will constantly creep up until it reaches the 3/4 mark, and then slowly go back down to the 1/2 mark. Can anyone tell me any ideas of whats going on??? Also, last night the Service Engine Soon light came on while driving on the freeway.
Thanks In Advance
#2 of 37 CLIMATE CONTROL-HEATER
Mar 02, 2008 (3:24 pm)
We bought an 06 Buick Rendezvous about 6 months ago. We have had problems with the heater all winter,it will start off blowing warm air and within a few miles the drivers side will turn cold. We have had it to the Buick dealership 4 times now . the last time they checked the tempeture at the vents on the dash. It was about 50 degrees outside and even with the windows down the drivers side was 72 and the passengers side was blowing 106 degrees. this was with the drivers side control set at 80 degrees.
They have replaced the AC control module and checked the actuators and they are opening the doors properly. The tech said there is a problem but they can't seem to fix it. Thanks for any help Dale
#3 of 37 More temp problems
Apr 12, 2008 (7:01 pm)
My 04 Rendezvous has had an overheating problem for about 1½ years now. All of a sudden out of the blue, it overheated one day. It also affects the heater temperature: when it acts up, the heater blows cold air. At full highway speed, the temp will usually go back down into or near the normal range and heater will begin blowing hot air again. A guy at AutoZone told me to turn two pressure release valves on top of the engine until water begins to seep out and then retighten. This works, but I'm told that it could be a seal that needs to be replaced which labor will be from $800-$1200 on. Does anyone know anything about this? I hate to spend $1000 on a mechanic's hunch!
Thanks for you help!
#4 of 37 Get second opinion before have head gasket fixed
Apr 13, 2008 (11:32 am)
Easter weekend our 02 RDV started acting strange. The temp gauge was all over the place and it was not heating when it was sitting still. I thought the worst, head gasket. I got it into the shop last week to get the problem diagnosed and it was the manifold gasket that was leaking and burning off the missing antifreeze. After I picked it up at the shop I asked the mechanic, not dealer, if he had ever seen a head gasket blown on the 3.4 engine. He said "NO" but added that he had replaced his fair share of manifold gaskets on these engines. It goes back in this week to get fixed. I'm being charged $750 to replace the gasket. I'm going ahead and having the plugs replaces as long as they have it in the shop.
Hope this helps anyone!
#5 of 37 Buick Customer Service Phone Call
May 06, 2008 (2:24 pm)
I just received a phone call from the Executive offices at Buick. I sent them a nasty letter letting them know that I had to walk away from my 02 Ren with ONLY 37,000 miles on it because I could no longer afford to replace wheel bearings and intake manifold gaskets. Somehow they thought apologizing would make things better. However, she did state that people need to call the customer service number and complain about all the things wrong with this car. I know we have all called at least once, if not twice to complain and yet they still don't get it. But, please everyone start calling AGAIN! Call and let them know about your gaskets, your wheel bearings, your fuel tanks. Keep calling till they figure out this car is a LEMON! The woman I talked to just could not believe there were this many of us that had the same problem and they had never heard of it. By far the most obsurd thing I have ever heard! The number is 1-866-608-8080. I was fortunate enough to be able to trade mine in (at a hUGE loss), but the dealership turned right around and sold it to some poor soul....

Hope you all know - there is a Settlement from GM go to www.dexcoolsettlement.com- the type of coolant they used causes various problems - but definitely affects the gaskets and wheel bearings - THIS CAR IS A LEMON - get out of it NOW if you can

oh yeah we have a lemon. My husband is so mad that we are paying on this that we will not ever recover the loss. Buick sold crap I love the car but from 30,000 miles first it was not holding antifreeze and then the heat and air wont work on high this was at 80,000 then the tires wear easily but hard to get, then the windows broke then the lamps go out all the time, then now watch out you people with coolant problems the gasket. what a shame it cost another 3,000 dollars but it will be parked and cant afford to fix it after the front windows falling so it will be parked paying on unless some dummy wants to pay for junk we owe 11,ooo on wow I will never recommend gm again oh and we had trouble with the lock system the back hatch and should add even more but frustrated
#8 of 37 Head gaskets and more costly repairs
Jul 27, 2008 (11:55 am)
The 2002 Buick after turning 100,000 and a few anticoolant not holding and window clips breaking and tire wear and only one tire fits now we had to replace the headgaskets , surpentinebelt and had the Dexcool removed that led to these problems. We were told mechanics love Dexcool and that is why. Well then 1 week later the cable from the battery was fryed in half by hitting a pully and we had it replaced and the clip that held it on that caused the problem. Well guess what now 6 days later the engine is nocking. I owe 9,000 for this crap and have spent 2800 dollars on it I hate this car now. How do I get out of this mess and what is the new problem? Im calling the mechanic Monday and how serious will it be anyone know? the fluids are fine he replaced most hoses the plugs and took out all of the dexcoolant and a few more things. thanks jensmith

Well we are going to file on the lawsuits with GM and the awful mess that has cost us ongoing problems. Now the headgaskets all the hoses the battery cables and the surpentine belt a 2800 in a month and 3 days later the engine is knocking in which the mechanic says it threw a rod and did not pay the towing and it has set 2 weeks now not fixed. He will probably give us another bill and it wasnt doing the knocking before. I hate this crap car and will probably work xtra instead of having surgery to pay the trash vehicle off get rid of them now befor the warranty is up
