2004 Buick Rendezvous - extremely unreliable horn (design flaw). I have narrowly escaped many accidents by sheer luck. Have had people backing into me & been unable to honk the horn because I could not find the very limited "sweet spot. " when the steering wheel is turned even slightly, it is impossible to find!.
My 2004 Buick Rendezvous has been in the shop 8 times in 10 1/2 months. Currently I am experiencing a loud noise (much like an air raid horn) while I am stopped in traffic and when I turn my vehicle off. It started back in April, the dealership could not recreate the noise, in the shop again 11/4/05 and again 11/11/05. I just do not feel safe in the car. I it is getting progressively worse, louder and more frequent, lasting longer. I purchased my vehicle 17 Dec 04 and the very next day had a break problem. My service record is as follows: 1) 12/20/04- abs light on - all wheel drive disabled 2) 01/27/05 - abs light on - all wheel drive disabled 3) 4/25/05 - abs light on all wheel drive disabled would not drive over 40 mph - 3) 4/25/05 - passenger side mirror clicking when vehicle is put into reverse 3) 4/25/05 vehicle makes a loud air horn noise when vehicle is turned off 4) 5-19/05 - abs light on - all wheel drive disabled 4) 5/19/05 - vehicle looses power when making left turns or on incline 4) 5/16/05 installed rear lift gate latch 5) 7/15/05 driver side mirror glass came loose 6) 9/01/05 - drivers side power window inoperative- 7) 11/4/05 - very loud acceleration - exhaust manifold leaking right exhaust manifold 7) 11/4/05 loud noise while driving vehicle, stopping in traffic and when vehicle is turned off 8) 11/11/05 wobble in left front tire- reface front rotors out of round 8) 11/11/05 took vehicle in for the loud air horn noise while driving, stopping in traffic and turning vehicle off - had a 5 minute discussion with service person about this and it did not even make it on the invoice.
The starter and horn did not always work. Thermostat and fuel gauge was not accurate. There had previously been a problem with the ignition switch and it was repaired due to a recall. The problem with the starter started in March of 2005. These problems have not been repaired as of yet. When the consumer took the vehicle it to the dealership they told her it was designed that way.
While pressing down on the horn, it failed. The dealer had inspected the vehicle several times and could not duplicate the problem.
