Vehicle has been to GM dealership many times for problems related to reduced engine power, stabilitrack, and traction control issues. Dealer replaced relay switches, problem appeared to be fixed. While driving on a busy road, engine power reduced, stabilitrack, and traction control warnings illuminated. Car reduced speed nearly causing an accident while driving and power steering failed. Police needed to help remove car from roadway. ECM replaced, appeared fixed for awhile. While driving on Highway 54, same warnings illuminated and car slowed itself from 60mph to under 30mph. Numerous complaints can be found about the 2013 Buick Enclave and other years and this problem. I believe it will cause an accident and kill someone one day, if it hasn't already. Class action suit was even filed, and unfortunately dismissed. I'm afraid to drive my car. It is at the dealership AGAIN and we've only owned it since February 2022.

My 2013 Buick Enclave started having problems back in December. When I was driving all of the sudden the car chimed about 3 times then all the sudden the dashboard read the following: 1.engine power is reduced 2.service traction control off 3.service stabilitrak 4.the engine light comes on at the same time, the engine power started to die down and I was barely moving. It was hard to steer and all power functions greatly reduced. Once I shut it off and restarted the car my check engine light stayed on but it switched from traction control off to traction control on. Then I was able to continue driving again. I bought this vehicle thinking it was a good family car but now after dealing with this problem and seeing all the complaints online and nothing being done, no recall, I made a bad choice. My children were with me when this happend a few times and we were almost rear ended because of it. The car literally stops working. This is a very dangerous problem and is not uncommon to GMC vehicles. I do not feel safe driving this car. I don't understand why GMC has not identified the problem. I am taking it to nimnicht dealership tomorrow in jacksonville. Hopefully they have some real answers before this car ends up killing me or someone else. Very disappointed GMC after reading all the complaints and nothing being done.

While driving my 2013 Buick Enclave traction control, service stabili track flashes across dasboard. The check engine light comes on and engine speed is drastically reduced. Car does not accelerate properly and rpms are not producing speed. Car is lethargic and signs begin without warning. Once engine is turned off and turned back on traction control rests and display messages disappear but check engine light remains on. Temperature or weather or type of road you are driving on does not play a factor in defect of traction control stabili track.

For the last six months I've had messages saying service stabilitrak, service traction control, engine power reduced, and then it slowed immediately which was frightening when you ate going 60 mph. My local dealership says its fuse nox which id arcing and will be almodt 600 to fix. Now my power steering pump is failing, terrible noises wgen turning and recalls have been issued to 2012S. Very tired of being afraid to drive my car.

The car started dying whether I'm on the highway going 65 or stopped or accelerating...so many different circumstances.. the car will be going along fine and all of a sudden it says traction control off, service stabilitrak system, engine power reduced and then it dies...it does all of this in a matter of 3 seconds then I'm left trying to steer with no power steering. This has happened probably 35 to 40 times in the few months that I have had the car. Yesterday was just the last time

The vehicle stalls during acceleration at about 1800 to 2200 rpn, more often after a stop of vehicle and is more noticeable at low speeds from 20 to 50 mph in both city and highway but more often in city streets, increasing the risk of a crash. No engine lights come on so mechanics are telling me that they can't diagnose without any codes on the engine. Vehicle has about 100K miles and this failure started about 95 K miles and getting worse with time. So far the engine has not shut off.

I have a 2013 Buick Enclave and for the past 5-6 months, the traction control off message and engine powering down message continue to pop up and my car while driving on the highway and goes into limp mode and quickly dies. I have to let it sit for a few minutes and then it resets but the engine light remains on. I have taken it into the mechanic and most recently the dealership but they have replaced everything twice and have not been able to diagnose the problem. So far the alternator has been changed, had two engine belts replaced, ignition and relay switches changed, updated all the software with no luck and about 7K in charges.

On 3/21/18 I was pulling out of a gas station to head to work. My traction control light lit up as well as my engine light. Warnings went across my dash stating "traction control off" "service stabilitrack" "engine power reduced" I couldn't go over 40mph. I made it back to work. After work only the engine light was on. The next day I drove it and by the afternoon the engine light had gone off. This morning, 3/23/18 I drove to work without any complications. Due to weather we closed our office early. I pulled out of the parking lot and my traction control lit up as well as my engine light. All three warnings went across my dash again and this time I could not go above 20mph. I made it home with my flashers on. Once I got home I let my car sit for a couple hours and then took it around the block. Again only my engine light was on. We will take it to the shop once the weather clears.

The contact owns a 2013 Buick Enclave. While driving various speeds, the vehicle suddenly jerked and the speed reduced to 20 mph. The check engine and stability trac malfunction warning indicators illuminated. The contact pulled over to the side of the road. The contact turned off and restarted the engine, and the vehicle returned to normal. The vehicle was taken to the dealer (alexander Buick GMC Cadillac, 1501 ventura blvd, oxnard, ca 93036) four times where it was diagnosed that the key fob alarm needed to be removed. The vehicle was repaired. The failure recurred several other times. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The approximate failure mileage was 70,000. The VIN was not available.

Lights on the dash board came on while driving in town at approximately 20 mph indicating AWD, traction control and anti-lock breaks were not working. Power steering also was not working. Vehicle taken to local GM dealer for repair. Assessment indicated need to replace power steering pump and electronic break module. The lights came off and on repeatedly over the next several weeks waiting on the repairs. The two recommended parts were replaced and one week later the same lights came on and power steering and other functions were lost again, indicating that the issue was not fixed by replacing these parts.

04/24/2014 3:56pm our 2013 Enclave suddenly went into reduced engine power mode while traveling on the interstate at speeds of 65-70 when suddenly speed was reduced to 35-45mph. My wife almost got rear ended. She contact onstar for diagnostics but they could not see any issue with the vehicle. (not issues or diagnostic codes found) when this happened the service stabilitrak light lit, traction off light lit, flashing service engine soon light lit. Car running rough and went into power reduced mode with sudden reduced speed while driving on hwy. To date this has now happened several times and until this past Sunday, 10/26/2014 had never stored a code to show a problem. This event showed a C0561 code stored. I contacted the dealership for an appointment but they were not able to look at it until today, 10/29/2014 at this point there apparently were too many drive cycles and the code had cleared. The dealership advised me to bring it in asap on the next event of this happening without turning the vehicle off, I have know idea when or where I'll be when it happens again.... this is a big safety issue with this vehicle and I just hope to not get into an accident from this before they are able to fix it.

While car is in motion (around 35-40 mph) the stabilitrak, ABS, A/C, blind-spot monitor shuts off; speedometer, gas gauge, battery gauge on dashboard all go down to zero (even when car is moving); engine is still running, but vehicle does not respond when accelerator is applied. If engine is turned off and allowed to rest a minute or two and then restart is tried, it either does not start at all or it will start, but will not move over 20 mph (just enough to get off the road.) if allowed to rest @10 minutes, engine will start again, dashboard is functional, but engine service light remains on. Acceleration seems "sluggish" when driving after this event, but can get up to @50mph. However, the first time this happen and the car got up to 50mph, the electrical system failed again (as described above) but I could "coast" home, thankfully. The weather is in 80S so A/C is on every time this happens (so far). This seems to only happen on short trips (5 to 20 mile trips such as for shopping, errands, etc.). it has not happened (yet) on longer trips. The first time this happened, the GM service rep said "confirmed ses light on wire harness out of firewall making contact on A/C lines. Has rub-thru on wire. Reposition wire and reseal." After 1 month (1,243 miles), the same exact incident happened again. GM service rep this (second) time said there are a lot of "communication codes" that indicate communication failures. GM service rep is still investigating issue. There is a service bulletin already for this problem (or one like it): Tsb ref# pi-1202, NHTSA ref# 10055394.
