Driving along and engine power reduced causing car to slow significantly - like downshifting two gears. Lights / traction control lights came on dash. Errors flashed - "Traction Control Off", "Service Stabilitrak", "Engine Power Reduced" All of this not only caused a slight bit of confusion, but placed us in danger with the flow of traffic. A repair shop replaced the gas pedal, however issue persists. Research indicates the throttle body sensor might be at fault - so we replaced this. Issue persisted, so I spent time online and found a GM TSB indicating a known issue and extending the warranty 10 years or 120K miles for P2138 Code. At this point, this issue persists intermittently, so we do not consider the vehicle safe to drive.

What does it mean when my car says service StabiliTrak and service traction control? Its main function is indicating that the traction system has been turned off manually to remind you to turn it back on when necessary. However, the StabiliTrak warning light may also signal potential damage to vehicle components that allow the system to work effectively. Loss of Power to Engine, Can't stear, feels like its about to blow up. It seems very usual for the Enclaves, Traverses and Acadias. And I had the same problem out of my 2014 Traverse LTZ

When accelerating engine will shudder, lose power and drive very bumpy. I have taken vehicle for service. We have replaced all filters, points and plugs. Given the vehicle a tune up and the problem has not ceased. The check engine light is not illuminated so the computer does not give the repair shop the information it needs to repair whatever may be occurring with the engine.

My vehicle just turned off while at a stop sign preparing to turn. It was towed to a mechanic that advised it was 2 quarts low in oil (oil was replaced 2 weeks prior) and that my battery needed to be replaced. They added the oil and replaced the battery. I drive the car ~ 5 miles home and it stopped again. This time when trying to start the car, there was an audible screeching coming from the engine and the engine was shaking. The mechanic offered to towels the car back to their shop. After inspection, they advised that "something" was broken inside the engine and that it needed to be replaced. My car has 75,000 miles on it; has had regular maintenance; there were no check engine lights and/or over heating lights. I was also advised by the mechanic that this is a common known issue with Buick. I'm now left with having to pay anywhere from $7500-$8500 to replace an engine on a vehicle that I've had for 2 years.

We purchased a 'certified pre-owned' 2012 Buick Enclave from royal Buick of sussex New Jersey in February of 2017. The car shut off on Friday January 11th. It was towed to rossi where we have been taken it for almost two years of ongoing maintenance, both scheduled and non, and have spent over $10K in the last year alone, on service that did not resolve the clicking sound coming from the engine. Earlier that day I had made the earliest appointment available which was 10 days later, on the 21st. After breaking down, we went to their showroom that following Saturday and were seen by charlie. He wrote up a very reasonable deal for $1K down with many incentives including one for me being a volunteer emt. Matt the sales manager came back and told us that my wife's credit score was not what we had claimed and qualified for a tier two instead of a tier one which now required a $6K down payment. We checked my wife's credit score on experian before we left rossi and got the same score we had given matt originally, which we showed him and to which he responded "we use a different system". we decided to keep the Enclave and repair it. The battery, solenoid and valves were repaired before the 21st and we were told that we could pick-up the car after it was test driven by the technician. We did not hear back from rossi service so we called and were told that when test driving the vehicle after the most recent repairs - the technician heard a clicking sound coming from the engine. Wow! that sounded very familiar as this was the complaint we had often submitted to rossi in the past and that we suspected prompted expensive and unrelated repairs. This time however they told us they would need to diagnose the engine, so the next day they called us and told us, the car, with just under 103K miles - 'needs a new engine'. no further explanation was offered except a quote of $6K.

While driving during light acceleration a mild to violent shudder occurs causing reduction or loss of controll GM states its normal. No specific speed happens any time at random. After researching extensively it is a common problem among this line of vehicles. Vehicle is an all wheel drive Buick Enclave platnum edition. No problem or solution is found. This is dangerous

When filling up the vehicle with gas, it is flooding the engine... there is also another issue that when you turn off your vehicle and the key is out of the ignition, the car and radio still runs...apparently, there is a fuse box that is causing this problem.

GM has know about the faulty timing chain and the seals used on the motor for years and continued to use it costing owners thousands of dollars instead of taking the necessary steps to resolve the problem before continuing the manufacturing process. I have oil leaking out from under the vehicle on the passenger side. This has caused a large amount of oil to accumulate on the engine, brakes and under carriage that posses a safety hazard. I have had to clean this off a few times.

My 2012 Buick Enclave started having problems on Feb. 14th. I was driving my daughter to school and all of the sudden the car chimed about 3 times (almost like the seatbelt sound) ' then all the sudden the dashboard read the following: 1.engine power is reduced 2.service traction control 3.service stabilitrak 4.the engine light comes on at the same time, the engine power is so low that I had to literally floor it, it wasn't even going 5 miles an hour, it was hard to steer and the brakes were hard to operate --- all power functions greatly reduced. Then the engine idles hard. This video is exactly what my car does: [xxx] there is no rhyme or reason when this happens---- very random. After a few minutes, I was able to restart the car and drive it to the dealership (the engine light was still on). Since the dealership can't duplicate the problem, they were unable to determine the cause for the problem. Since then, this has happened 10+ times. Recently I was going about 75 miles an hour, on the interstate, the car chimed, all the same things on the dash board, I went from 75 to 20 in seconds. Yesterday (6/11/18) was the last straw. I was going 45/50 on a major roadway when my car stopped working again. There was no shoulder to get to - an 18-wheeler carrying a large tractor had to swing into the next lane to avoid hitting me. It is only by god's grace that no one was hurt yesterday. Once the chime sounds, the car literally stops working. This is a very dangerous problem and in looking on the internet it is not uncommon to GMC vehicles. I have children and do not feel safe driving this car. I don't understand why GMC has not identified the problem. I found this video on-line that seems to identify the problem.

The timing chain failed on my Buick Enclave. This is a known defect that should be covered by GM under a recall. It is happening frequently to other owners as well. It is a safety issue because if it fails while driving it can result in accidents or injury. The issue occurred while moving and impacted performance, but did not result in an accident for me. I had the issue repaired by a mechanic.
