We purchased a 2011 Buick Enclave for what we thought was a great deal. We were prepared to pay for basic maintenance right after purchase. The check engine light came on as we were driving on the highway. I noticed loss of power while on cruise control(set at 65mph) and the vehicle started shaking. I noticed the RPM jumping from 1 to 2. we took the vehicle to Buick for repairs. We had a tune up, 2 catalytic converters replaced, 3 O2 sensors replaced along with one other one that I'm not sure the name, oil change, struts and shocks, rear sway bar links, air filter, and a gasket manifold. We have not had this vehicle longer than 2 months. The vehicle is still doing the same thing. Today after we picked it up from the shop(no check engine light) we drove it on the highway and now the service traction control light is on along with stabilitrak control. We have 6 children. This is dangerous. What are we to do?

I was driving in town at about 25 miles an hour when my vehicle shut off the traction control and my vehicle wouldn't go above 15 mph. Dash said service traction control.

I purchased the vehicle on 11/4/19. The dealership, salesman or service department. Didn't inform me or put it in writing that the crankshaft sensor was faulty on the vehicle. John Eagle Acura didn't consider safety first. On 11/7/19 at 48,076 miles the vehicle won't crank. It was cold and rainy so I didn't drive the vehicle. On 11/17/19 I drove the vehicle to church at 48,124 miles. When I got out of church it won't crank. I called the dealership on 11/18/19 and told them about the vehicle. They told me to bring it in. I brought it in on 11/19/19 at 3P.M. I asked the service department what was the problem because the vehicle won't crank. They told me that it is the crankshaft sensor. I told the salesman that you knew it was the crankshaft sensor and you put my safety at risk. Because you and the service department and dealership knew that the crankshaft sensor was faulty and my safety was at risk. He said to me and my husband that he knew and said that he should have given me a loaner car. But he never told me about it.

On 3/31/17 returning from spring break and was going 70 mph in passing lane on interstate 65 near cullman, Alabama and my car shut down, the ECM shut down no warning lights came on, no warning from onstar that there was a problem, I cut into the right hand lane in front of my sister inlaw and nearly was side swiped, I had no breaks, no steering, everything shut down. Some kind of electrical short caused the ECM to fry. Throttle body also was replaced. Something was causing a dead short. Had my sister in law not been paying attention she surely would have side swiped me when I went down into the other lane, 5 people in my vehicle and 5 in hers and traffic was bumper to bumper. I also reported and filed a claim with GM worked with craig a senior adviser at GM. Case# 8-286830. I also field a complaint with onstar. Of course all say my car is past warranty but I feel this is an electrical problem that could certainly cause deaths. Perhaps a recall could or should be done. I think there might have been on newer models but not 2011. We did not have an accident but was 6 hours from home and stranded, having to find a rental car to get home. My car was towed to bill smith Buick GMC and it took them from Monday till Friday to figure out the problem. They ended up calling GM techs direct to try to detect the problem.

While driving on the I495 beltway in md a warning chime sounded and the driver's display stated the " service traction control, service stabilitrak", then displayed "engine power reduced". this occurred while driving at 60mph in heavy traffic. Loss of power made it very difficult to maneuver the vehicle from the center highway lanes to the shoulder. Loss of power nearly caused an accident due to cars traveling at speed from behind. Wife and two young children in the car at the made situation extremely stressful!! followed instructions in driver's operating manual( turn off engine, wait 15 seconds and turn vehicle back on to reset system). This process worked but we had the repeat the process two more times during the 40+ mile drive home.

December 2014 lift gate was up and suddenly came down and hit my wife with great force. This happened twice but not consistently. Subsequently was taken to a Chevrolet/GM dealership, found both struts not holding pressure and were replaced at owner's expense. On the morning of January 9,2015 driving during a snow storm on an interstate suddenly vehicle lost stabiltrab, traction control and engine power was reduced to 15 mph. Due to the weather traffic was going slower than normal. Car driven to a Chevrolet/GM dealer where the throttle body was replaced at owner's expense. On January 14, 2015 owner brought car to have power steering pump replaced due to GM September 2014 notice and owner informed that power steering rack was leaking. Although not replacing the power steering rack would lead to failure of the new power steering pump, this component was not covered. Owner paid a portion to have the rack replace. This repair required a front end alignment for which the owner paid for.

We were driving down the highway at 65 mph the stabilitrak / traction control light came on followed by an engine reduced power warning and the vehicle slows from 65 mph to 30 mph in about 3 seconds. The error message clears itself when the vehicle is turned off and left off for 1 to 5 minutes. The second time this happened we took it to the dealership and they reset the codes as a check engine light was also on. The check engine light came on again and the error message code indicated an idle problem. The dealer diagnosed and the tsb stated to relearn the idle which cost about $220. This problem occurred two more times with similar decelerations from 45+ to about 25 -30 mph in 3 seconds. The car forums on the internet for Chevy traverse, GMC acadia list many people with similar issues. Many have called GM and have been told that GM is not aware of this as a major problem. Some claim there was a private recall on the 2010 models.

On March 27 2014 my Buick Enclave gave me an error message on the dash while driving on the highway traction control off, stability transmission needs service, and reduced power came on.the car went from 60 mph to 50 mph suddenly but then cleared up.I took the car into the dealer to be serviced on 03/28/2014. The local dealer stated that they found the issue and corrected it.on April 16 2014 I had the same issue however the event was much worst. I was on the a major highway doing 65 mph. The car did not give me any indication of any isssue. The dashboard displayed traction control off, service traction, and service stabilitrak and very quick and suddenly I lost all power to the car while traveling down the highway at 65 mph. The speedometer stated I was still at 65 mph however the car was not traveling at 65. I tried pulling on my hazard lights but they did not work at the time. The power steeling on the vehicle did not work. The gas pedal did not excel the car. I was almost hit by a tractor trailor who was traveling behind me. I tried moving to the slow lane however the car had no power sterring but the engine was on and the gas pedal was to the floor but the car was not acceleration. I had no power in the car, I was able to get to a safe spot were I tried turning the car off and back on. That did not solve any issues except for the hazard lights. I was then able to put on my hazard lights. The car never gave me an error that I had reduced power. Everything occurred in about 2 minutes. I immediately contacted the dealer to have the car towed. I have major safety concerns about the 2011 Buick Enclaves!!!!! I am very lucky that I was not killed on hwy 540. I don't think my air bags would have deployed if I were hit by a tractor trailer or car. Nothing was working in the car. Please call me with any questions!!

Driving on highway. Warning light for stabilitrack came on, then engine power reduced light. In seconds no power to vehicle. Could not accelerate at all and vehicle slowed on its own. Extremely dangerous in traffic when trying to pull over with no power. Manual says turn off car wait 15 seconds to correct problem. Assuming you don't get killed pulling over first, nice idea. Doesn't work. Had to stop vehicle more than ten times on way home due to same problem. Brought vehicle into dealer. Same problem persists.
