I purchased this vehicle used in December 2014, the very first night driving it home, the engine would nit start. I immediately called the dealer, took the car back and watched as they ran a diagnostic. Nothing was wrong with it. I did some research and it seems to be a normal issue with the make and model. Then I noticed the faulty gas guage, reading low fuel then all of a sudden I have gas. Again, contacted the dealer, took it back and yet again, diagnostic ran with clear readings. I looked up thaylt issue and of course, complaints about the same issue were common. Finally, on April 9th I was on my way home and was involved in an accident. It was a front impact accident which totaled the vehicle. The air bags failed to deploy. The windshield was completely shattered, glass flew everywhere. After the front impact, the vehicle rolled over then landed on on the passengers side. How is it safe to have multiple complaints about serious issues and nothing be done about it by the manufactures! I almost lost my life due to the airbags failing which is a, yet again, a common complaint!

The problem happened while driving, the engine shut off without warning. The 'reduced power engine' light came on. I coasted to side of road to let folks get by and sat and waited for about 5 minutes and tried the key and the engine started. No codes stored. No check engine light. I still had power windows, radio, lights and horn. The silent engine happens at least twice every other day. Noone has a sense of what is happening and the safety issue is when I am on the interstate and the engine suddenly dies out. I am a little worried since this is the only car I have to drive to get me back and forth to work.

Engine cut off and reduced engine power light came on while driving down road. Power steering, brakes and everything else completely quit unexpectedly. Could restart after letting sit for 10 minutes, but continued to do this all the way home. Took several more trips out around town and problem just got worse. Was a very dangerous situation, being as it would simply cut off in middle of road while going 55-60 mph and almost unable to keep under control and keep from being hit by other drivers. Parked it at home and researched problem online. Everything I found stated others with same issue would take theirs in for testing and repair and could get no satisfaction, multiple and various parts would be replaced and problem continued. Have replaced alternator, spark plugs and wires, throttle body, ignition switch, cleaned wiring harness connection under drivers seat and checked for corrosion, cleaned mass air flow sensor, and ordered an engine control module, but just found out that it needs to be programmed to the vehicle to work (currently working on finding someone to do that, now). Cannot afford to take to dealership, and after reading all the other dissatisfied individuals info., I do not feel that it would do any good since no part replacement seems to work. Seems like this is becoming a common problem for Buick Rendezvous vehicles, from what I can see from the other recent complaints. It is also a very dangerous problem. Engines should not stall out while going down the road, thankfully I am just an experienced enough driver that no injuries occurred. Would not have been the same thing if my son or daughter had been driving. It will do no good to file this complaint and no investigation or recall will occur, I'm sure, but at least I can join the other listings showing this is a common problem. Love the vehicle, hate that for the price I paid, I only got 100,00 miles.

I was traveling down the interstate doing the speed limit of 70mph. Out of nowhere, the car flashed "reduced engine power" light and would not accelerate. Then the "service engine soon" light came on and a red battery light also. The car lost all power and power steering. I had to force the car into the emergency lane on the interstate without wrecking. I turned the ignition off and let the car sit for a couple of minutes and it started back up. I made it about 10 miles down the road and it did it again. Car will not run more than 10-15 mins without shutting off. Will not drive this car!!! very dangerous for everybody!

The contact owns a 2006 Buick Rendezvous. The contact was driving under 5 mph and approaching a stop sign when the vehicle stalled. The failure would recur sporadically. The vehicle was taken to the sears several times where the failure was contributed to a loose battery connection. The failure persisted and the vehicle was taken to the dealer, who was unable to diagnose the failure. The vehicle was not repaired. The VIN was not available. The manufacturer was notified of the failure. The approximate failure mileage was 62000. Updated 3/25/14 the consumer stated the vehicle was fixed. There has been no failure since. Updated 04/23/14

At any given speed the "reduced engine power" light comes on and the car comes to a complete stop. There is no power steering, etc. It's extremely dangerous because of being able to get the car off the road. I am reduced to driving on the service road and still do not feel safe. Interstate is out of the question. After reading many reviews regarding repairs, I am not inclined to spend a tremendous amount of money for repairing a car that obviously no one can repair. I believe the manufacturer should be responsible for recalling this car. It's extremely dangerous and I cannot believe there have been no fatalities due to the fact at any given time the vehicle loses power. I noticed there was a recall on seat belts, believe me that is minor compared to the terror of being on an interstate or secondary road with grandchildren and the engine on your car completely stops. Please intervene on behalf of myself and countless others. Obviously this vehicle is not safe for anyone to drive. I will be parking mine because from what I have read it appears this problem is a factory one and the mechanics cannot repair these cars. Thank you for your time and consideration and hopefully with enough input the manufacturer will begin recalling the Rendezvous and make it a safe vehicle. By the way, on one occasion I started the car, and while still in our garage, "reduced engine power" light came on. Thankful I was still in my garage that day. Shortly after trying a few times, the car started, then on the way to pick up grandchildren, died again on a two-lane road and had to find a tiny area to pull off. I am not in a position to buy another car. I haven't been able to read where anyone has actually had their car repaired. I bought this car especially for driving my 4 grandchildren. I'm 72 and now unable to have that pleasure due to the danger of stopping.
