2014 Buick Enclave: check engine light

Filed Jul 10, 2026 · Engine, Fuel system · VA

The engine, power steering, stabilitrak, and reduced engine power (vehicle would essentially die while driving at random times). My safety AND others were put at risk when I am traveling down the road/interstate and the engine just cuts out and am no longer able to accelerate to any speeds, causing me to have to pull over to the shoulder WITHOUT ANY ENGINE POWER. Yes, the problem has reproduced and confirmed with the dealer I purchased from. Vehicle has not been inspected by the above mentioned. Only had it inspected by the dealer I purchased the vehicle from. There were no prior lamps, messages, or other symptoms until it just showed up while driving one day. It happens at the same time as the engine loses power and acceleration. The check engine light comes on, within 2-3 seconds the engine "dies" and then the "Service stabilitrak" pops up, as well as the warning "Reduced Engine Power". This first appeared on approximately on 05 JUN 2026. Vehicle was purchased on 12 MAY 2026.

1)Numerous Gas Cap ‘red warnings’ were fixed each time 2)Driver-side ‘Seat Belt’. Fixed. 3)Check engine light ‘off and on’ will quit after 5-10 minutes 4)Stabilitrak/Traction-control (red light warnings), on and off, finally stayed on: Took back to Parsons of Antigo, WI dealership for repair; they said it was fixed. I left dealership at their closing time, started car, the car was shaking, called dealership/told them what was happening/they said bring it back on Monday—this was a Thursday evening after 6 PM! a. I had to drive this ‘shaking-car’ home approximately 35 miles away, while going about 30-40 mph/in a shaking car, seems car wanted to stop. Very frightening in the dark night. b.I had a wrecker come and take the car back to dealership. I do not care to deal with dealership after this—I changed to different dealership. c.About 3 years ago, while driving on US 8 outside of Rhinelander the car just ‘simply’ went off the highway; I quickly managed to bring the car back onto the highway blacktop. Is this for real? i.Until July 2025 I worked 40 hours/week and I believed and trusted that the repair services would inform me that I needed to beware of ‘this or that’; when usual car maintenance was completed. d.In 2019, going through a ‘Traffic Circle’ in Green Bay, WI area; this vehicle just would not stop (as I need to wait for cars coming from the left) and somehow, I made it through that circle without hitting another car or damaging this car! The police officer asked, ‘What happened?’ and I told him, ‘I have no idea what happened’. I was given a ticket for $175; that was mailed with a check before a certain date. i.Now, after reading all the ‘recalls and complaints’ I can understand ‘the why’ I had to endure driving with this vehicle’s unreliable mechanisms” throughout these years. 5)2021 Air bag ‘red light’ for Service recall Airbag/serviced. 2-19-2026 airbag another warning to replace again. PeopIe say this car looks like new. A 'lemon' buy

I own a 2014 Buick Enclave experienced two major safety‑related failures. First, while driving on the highway, the vehicle suddenly lost throttle response and triggered a check‑engine light with code P1682 (Ignition 1 Switch Circuit 2). After replacing the ignition relay in the under‑hood fuse box, the issue seemed resolved temporarily. A few weeks later, while stopped at a traffic light, the vehicle displayed “Traction Control Off,” followed by “Engine Power Reduced,” and began shaking violently. The engine warning light turned on, and the car became undrivable in traffic, creating a dangerous situation. A mechanic later confirmed no failure in the replaced ignition relay. The root cause may be a design flaw in the fuse box and its bottom wire‑harness connection, which is known to loosen because the two internal securing screws do not get tighten at all, its freely moving and not securing anything. This potential defect has reportedly affected multiple GM vehicles from 2013–2015, posing serious safety risks and potentially leading owners to spend significant money on repairs without resolving the underlying issue. In Buick Forum, thousands of customers experiencing the same issue, spending thousands and suffering financial implications and severe safety threat just for a careless design and carelessness in addressing a small design issue!!!

On a few occasions, while driving, the car will shut completely off. In these incidents, wrecks could have been caused. I almost ran in ditch one time and almost hit a stop sign because the steering wheel wouldn’t turn since the vehicle was cut off. The latest incident happened on 10-22-2023. On several occasions, while driving, the traction control light will come across the dashboard “traction control off”, immediately after the engine light will come and another alert come across the dashboard “reduced power. As you pull over or begin to stop, the car will shake really bad and another alert will come across the dash board saying “service stabilitrak.

Stabilitrack continues to cause problems with the car. I was traveling 60 mph and the stabilitrack and check engine light reduce engine power and car is unable to drive over 40 mph. This is a serious concern when on the highway. When this issue is tripped the car shakes and runs roughly. This car continues to have air bag relay or electrical issues even after fixing the seat belt harness which was recalled. This has been repaired by the dealership no less than 3 times and it feels as we are replacing parts which do not fix the issue. Having the car slow and limp home on a highway is dangerous and happens without warning. The dealership dismissed the airbag light and the second look says repair is needed for safety. So frustrating GM.

Vehicle warning lights come on randomly - airbags, check engine, ABS. They will light during drive time, then blink out for no apparent reason. Instrument lighting may or may not light when vehicle is started, and instrument console and/or entertainment console will not function when unlit. Again, this happens randomly, and often resolves just as randomly. Have had vehicle inspected by dealer without any issues identified. Issues have been ongoing for a number of years. They can occur without regard to vehicle being in motion.

In 2016, and again in 2020 after the dealer first fixed the issue, while driving at high speeds, on highways, also in the rain, again at a stop light, the vehicle suddenly decelerated, causing the potential for a very serious accident. The warnings then displayed on the dash included reduced engine power, service stabilitrak, service traction control, and traction control off. The vehicle only then drove at slow speeds, sputtered and jerked, and felt like it might stall. When able to pull over, at times turning off the car reversed the problem. Sometimes the check engine light was on, sometimes it wasn't. Sometimes it would drive fine and then out of nowhere, it would happen again. In 2016, the dealership had a difficult time finding the issue. After several days of driving it, they identified the problem as a fuse box issue and replaced the fuse box. This seemed to fix the issue until it happened again in 2020 while driving. On a road trip, it happened while on a highway, again at a red light, and while on a highway again. Each time, we pulled over, turned the car off for a while. One time in particular, the issue didn't go away after turning the car back on.

Takata recall in the almost 3 years I've owned my 2014 buick enclave, there have been 2 occurrences with the same transmission issue. The codes are: p0700, p182e and p0306. The engine light comes on and flashes for roughly 30 seconds. The first occurrence was in the city, about 35mph and the second was on the highway with a speed of 60mph. Both times I've pulled off the road and the light disappears. When I take it in, the codes are pulled and cleared. The mechanic can not get the code to reappear. My buick has never shifted right, noticing padding and jerking before and after switching gears. The mechanic said this is a common problem with these transmissions and the repair bill will be around $3,500.00 for a new transmission. A 5 year old vehicle should not be having these issues!! Buying a 2 year old vehicle at $28k, owning it for less than 3 years and having to replace the transmission does not sit right in my book. Gm needs to fix this transmission problem and soon!

About a year ago, our 2014 buick enclave awd, began shuddering while driving and lagging when trying to accelerate. 4 months ago, the vehicle's check engine light came on while I was on the freeway. It also displayed the "traction control off" 'stability control off" and "engine power reduced" signs on the dashboard. My vehicle went from 75 MPH to 25 in a matter of seconds.. While I was on the freeway with my two children in the car! I was able to pull off to the side of the road, turn the car completely off and turn it back on again. This seemed to reboot the computer, but the check engine light remained on for several days. 4 months later, this has now happened about 16 additional times, 3 while on the freeway! We've replaced the throttle body, throttle body gasket, mass air full sensor, pvc valve and the power train module relay. We are continuing to have problems!! The most recent, this morning while taking my children to school. This on top of having to have the A/C evaporator replaced at least once/ year since we bought this vehicle brand new off the lot! I'm a little tired of putting my children's lives as well as my own in danger every time I take them and pick them up from school!

Car will slightly shake while this happens. Car will some times also shut off completely and not restart until codes have been cleared.

Fuse box has been replaced. Pcm and ignition switch have both been replaced. Gives code p1682 which is ignition 1 switch circuit 2 code.
