Engine would shut off while driving or not start after driving. Engine power reduced light comes on and speed throttled down to 20mph, check engine light stays on now. Replaced relay box under hood since a connector was found burned. Have also replaced the computer, alternator, ignition relay switch, fuel sensor relay. Has not been driven on highway at all for fear of it happining in high speed traffic. Problems have been consistently happening since purchased Oct 2015.

I've had so many problems with this vehicle. Spent over $4000 in repairs in the last 6 months. The first problem I had was while driving on the highway the reduced engine power light and traction system light would come on and the vehicle would just decelerate and wouldn't go over 15mph. I had it repaired once and was told it was the wiring harness and then 2 months later the same thing happened again had it repaired and was told it was the wiring harness and computer that needed replaced. And now I'm having a similar issue but this time the service engine soon light is flashing but the car doesn't want to accelerate and takes several seconds to even get up to 35 mph. I had this repaired once and was told it was a wiring/fuse issue and that the car was only running on 3 cylinders and literally 2 days after the repair it started happening again. This is ridiculous. My mechanic even told me I should just get rid of the vehicle because it obviously has major wiring issues. It only has 130,000 miles.

Rendezvous 6-cyl

  • 123,670 miles
We were traveling on the interstate at 65 miles per hour on June 5, 2016 and June 11, 20176. The vehicle just went totally dead. The motor, the power steering, everything...went totally dead. I was in the passing lane and a transfer truck was on my tail and I had to go into the grass median to avoid getting smashed and the truck had to swerve over to miss me. After repeated attempts to restart the car, it started. I went straight to an auto repair shop and they checked my starter, alternator, and battery. Those things were ok and they suggested maybe I had bad gas. On 6/11/13, I was on the road again doing 65 and with no warning whatsoever, the vehicle went dead just like the week before. I was able to pull into a turn lane barely avoiding a rear end collision. We took the car to a repair shop.. when we went to get the car, they told us it was the ignition part that GM was recalling. The mechanic tapped on the part while the vehicle was running and it died immediately. He also asked us if the airbag warning light had been coming on. We said yes it had been for about two months and the check engine light had been on a lot during the last month. We contacted the GM and talked to customer service who told us the Rendezvous was not yet on the recall list and I would have to pay for the repair myself. I went to the local GM dealer, [xxx], and the manager told me he could not help me. He said they were independent of GM and if they fixed it, they would not be able to recoup the cost from GM. Do I have any other recourse" is it going to take a family being killed in a Rendezvous before GM will take responsibility for this very well known part defect? I have lived through two miracles where my family could easily have been killed because of this known defective part. If I have to pay for this repair, is there a way I can be reimbursed by GM" information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I plugged my cell phone into the car charger in the front console. When I returned to the car after about 15 minutes, it was filled with smoke that was coming out of the car charger. I immediately unplugged the charger. I tried to start the car and it was completely dead. After examining the fuses, I noticed that the one for the charger as well as the one for the interior lights was completely melted. After further research it was discovered that the wiring harness under the dash was completely melted - had I not gone out when I did, the car probably would have caught fire. This should never have happened - there should be safety features int he vehicle to cut the power to the charger immediately if there is a short. It was towed to the dealer last night. They are claiming this is not covered by warranty though this is obviously a problem with the Rendezvous. Besides this - the check engine light has been on twice, the transmission is about to go, the alarm system never worked as well as the remote start. They sold me a vehicle with known issues and don't want to stand behind it. I don't think I will ever buy a Buick again.

Rendezvous 6-cyl

  • 68,847 miles


On Sept.21, 2010, while driving my child to school. I pulled out into the highway where my 2006 Buick Rendezvous stalled out and the service engine light soon came on. On Sept.22, 2010 I took my Rendezvous to the Buick shop where they scanned for codes that came back as the camshaft position sensor faulty. A new sensor was installed and codes cleared on Sept.23, 2010. On Sept.23, 2010 my Rendezvous stalled again and service engine light soon came on while driving on the interstate. On Sept.24, 2010 I returned my Rendezvous to the dealer, they scanned for codes and the codes came back as the camshaft position sensor faulty again. After a thorough investigation the mechanic found that the part #15306175 a connector and part #15832816 F-harness on the Rendezvous had a short ground and melted wires. Part #15306175 connector is an egr power valve solenoid connector and part #15832816 F-harness is the harness asm-eng wires. The harness in question was sitting on the top of the battery because of a flaw in the design of engine wiring and where the wire is made to hook on the engine belt cover. This caused the wire harness to be covered in battery acid and corrode and melt the wires. My 2006 Buick Rendezvous had 68,847 miles on the vehicle at the time this problem started with a repair cost of $330.64 for the camshaft position sensor faulty code which really was not the problem to begin with to the cost of $1,113.95 for the replacement of the engine wiring harness being flawed. Because this to me is a safety issue that can and could be prevented. I have checked out other Buick Rendezvous on sale and owned by others in my area and the same problem is occurring on these vehicles. The electrical short and melting of the wires could have caused a serious accident for me and my family or other's on the road.

The contact owns a 2006 Buick Rendezvous. While driving between 25 to 35 mph the vehicle would stall and become very difficult to restart. The dealer offered to inspect the vehicle but she declined and stated that they would improperly inspect the vehicle.
