Buick - Rendezvous :: Speedometer Will Slowly Increase Or Decrease In Mph And Randomly Stop
Apr 2, 2011
Recently my speedometer has been acting wacko...and continues to do so. Two to five minutes into a trip it will slowly increase or decrease in mph's and randomly stop (or continue) as it pleases regardless of how fast or slow I am traveling. Several mechanics checked it and test drove it and no one could figure it out. The devices they used to check the speedometer indicated it was functioning properly.

I am having some trouble with my 02 Buick recently. The acceleration from a stop is very sluggish and gear changes come slowly, although they still seem to shift smoothly. The first thing I did was check the fluid levels and I can find nothing wrong there. The trans fluid was last changed 3 years ago, but the level, color, and smell are all normal so surely that couldn't be the culprit ?Unfortunately, that about exhausts my diagnostic skill.

Since I got Prius I've noticed that driving at 50mph returns 80+mpg , 90+mpg if I let it gently glide at -1mph per 1 mile. As it gradually slows down, the mileage starts to decrease. By the time I get down to 45 mph the mileage shows around 70mpg,
I get down to 40mph, I'm only getting 50mpg. When I keep my speed between 40 and 45 I get about 52-55 mpg for the day. If I keep my speed between 45 and 50, I get 55-60mpg for the day.

The volume control on my stereo stopped working today. The radio turns on, but the volume controls do not increase/decrease the volume. It is stuck at whatever volume it was at before this problem started. When I turn the volume knob, I see the volume level numbers increasing and decreasing in the upper right corner of the touchscreen, but obviously the volume stays put.

My Santa Fe is doing a pop sound, like a clunk, when I increase or decrease the speed. It is just one time noise every time the speed changes. Like when the "gravity center" changes from the car front to rear or vice-versa.
I notice already that doesn't happen when it's shifting, neither when I go over a speed bump.
It happens in all gears, but is more noticeable up to the 4th gear.
Also, usually I can hear this noise, a little bit lower, when I'm stopped and change the gear from P to R or vice-versa.
My Santa Fe is a 2011 model with 70K kilometres ....

Sometimes the volume button on the stereo nor the buttons on the steering button do not increase or decrease the volume. I can turn the stereo on and off - still the same. If I turn the engine off and on - this issue goes away. It's only just started happening in the past few weeks.

How do you decrease/increase the sensitivity of the Remote Touch Interface (console-controlled pointer)? I'm really missing the mouse pointer I had on my previous ES, and am sick of overshooting my target in making a selection.

Symptoms : You will hear a squeaking noise from the passenger side of the car. It will increase and decrease with engine RPM, and apparently can be heard from inside the car as well. This noise is from the tensioner bearings failing...which, if gone untreated, will then cause the serpentine belt to fail.
If the belt fails, it seems that the battery light will come on, followed by engine coolant temperature spike (overheat).
Bad tensioner sound:
Confirmed failure shortly after this sound:

I turned on the climate control this morning when I started the car and tried to change the temperature, then for some reason until the car was warmed up the climate control went to lo and seemed like it was locked there.
Once I the car got warmed up, the climate control worked was normal. It seemed like the increase/decrease controls were locked.

2004 Prius and I have lots of static in the AM radio. Some days it is worse than others mostly I am unable to listen to it. If the car is in accessory, the static in the AM radio is not there. As I drive the car the static will increase or decrease based on the proximity to the overhead wires. There are days however where the static will be hardly noticeable. I've owned the car since 2006 and have always had this issue.

I recently had the transmission rebuilt on my 2004 Buick Rendezvous. After 150,000 mile and noticeable slipping, it was time. When I got it out of the shop, I noticed that acceleration was sluggish, When you would stomp on it, the engine would start to "bog down" while the RPMs would hit 5000. Took it back into the transmission shop where they checked it out and said transmission is operating fine, but they show an o2 sensor issue. They suggested that it might be this sensor or that it may need a tune up or perhaps just new plugs.I took it into my mechanic and they checked out everything, plugs, fuel filter,and replaced sensor. Afterwards, they said that they get no misfire codes whatsoever, and say the engine runs great. Unfortunately, the acceleration problem did not go away I am stumped. The mechanic says its the transmission; the transmission guys says it's the engine.

This Buick began stalling, then difficult to start. We have replaced fuel filter, fuel pump and sending unit. It will start sometimes and either run smoothly for a few minutes or run rough stumble and backfire through the throttle body. It has not thrown a code thru any of this. How to proceed?

One year ago, after driving 8 or so hrs., at 108,000 mi, my 2003 Buick Rendevous started making a groaning sound which would last 15-30 seconds. When exiting the turnpike, the sound lasted nearly 1 min. The next day, the Buick dealer could find no cause but put a new serpentine belt on it which solved the problem for a few months. (I had previously replaced the serpentine belt at 96,000 mi as routine maintenance.) After a couple months, I heard the sound again and took it to my local Buick dealer who could find nothing. It was o.k. for about 6 mo. Now it groans again. My local mechanic heard it but could find no cause. It groaned almost constantly a couple days ago while I was driving in slow traffic w/the a/c on but quit when I turned the a/c off. It sometimes groans with the a/c off, especially on a turn from a stop sign. I now have 114,000 mi. The sound seems to be originating from the engine.

I have a 2002 Buick Rendezvous CX (2wd no traction control). My ABS is throwing a C0040 and C0035 code. After reading some info it seems to most likely be a wiring issue. Would a wiring issue also cause brake performance issues? At times when I brake there is a slight "pulsating" feeling in the pedal accompanied by a noise like I'm on gravel (not the bad pads/rotors noise). I can also here a very fast (but faint) clicking noise when I brake at low speeds.

I just had all the plugs and wires replaced on my car. The mechanic said this (MAY) fix the problem.I am still having a problem with the car shifting very hard,and make grinding noise coming from the rear. It sounds like the transmission is falling out! Does it maybe the clutch sensor. I have had it to 2 shops and analyzed, and they have no clue.

130,000 miles transmission shifts hard in every gear sometimes other times it is completely fine. Thought about servicing it with new fluid, filter, flush but have heard that this could cause problems since so many miles...

The wife has a 2007 Buick Rendezvous that makes loud growl after starting. Doesn't happen immediately, sometimes it doesn't happen at all. I have not been lucky enough to have it make the noise when I have the hood up. But from inside the car it sounds like it's coming from the driver side close to the firewall. I know "belt noise" when I here belt noise. This IS NOT belt noise.

When the radio is on AM and the car is running, there is static . When the car is turned off and the radio remains on, the static disappears. We have had the antenna replaced, the radio replaced and all worked for a while but now the static is back. 2006 Buick Rendezvous...

My truck has this rapid machine gun type start, but not always. It always starts though. I had the alternator tested at O'Reilly auto. They said it was good. I have also been trying to see if there is a possible relation with my clicking sound. I guess it might be more of a steady tapping. I thought it was possibly a lifter. My neighbor that works at one of the quickie lubes said he would take a look. He listened with a screw driver and said he did not here the clicking/tapping sound from the engine.
I showed him how when you accelerate on the gas it gets faster and louder. He said it sounded like it was coming from one of the pulleys. There is no kind of squeaking though, just a loud obnoxious tapping noise. He said that he thought it could be a bearing.I am just trying to think if there is still some kind of alternator relation, because also at times going down the road I notice that the lights on my dash flicker a bit. From looking at all of the pulleys, they all look pretty steady. Although, the crankshaft pulley on the bottom does look like it has just a little wobble. We did not have a long enough screwdriver to listen for the tapping in the pulleys. Also, the serpentine belt is good on it.

Vehicle will not respond to anything. Remote key access wont work. No clicking or starter movement. No lights, radio, etc. Not the battery.

I have a 2002 Buick Rendezvous with a 3400 sfi engine. The vehicle runs perfect except random stalling when you are stopping or pulling out. It seems the vehicle has a random low idle unless the air conditioning is on at which time the idle stays around 700 and the vehicle does not stall. I had a repair shop clean the throttle body which made no difference. I replaced the IAC valve and air filter yesterday and still no change. Also was wondering if you unplug the IAC valve should the idle change because it has no effect on the idle at all when I unplug it while the vehicle is running. Really cant afford to just start replacing item after item with no result.
