2014 Buick Enclave electrical system problems

“My vehicle starts displaying traction control on the dash then says reduced engine power and looses power starting until u stop turn it off and crank it back up. Sometimes it runs really rough and you have to crank it back up. The ac goes in and out on it, sometimes it jerks while driving, after having a new transmission put in, 3 starters, 2 batteries! Everyone keeps telling me it’s something electrical but can’t figure out what or where. Replaces mass air flow sensor also”

“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…”

“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…”

“The "Service Airbag - Passenger" warning light suddenly appeared on the console of my 2014 Buick Enclave. Once I arrived home, I Googled what the light indicated and I also sorted through mail I had recently received from Buick that notified me of a recall. Convinced that I needed to resolve the issue promptly, I contacted the dealership we purchased the vehicle from and they informed me to come in so they could hook the diagnostic machine to the car to determine the codes. I went into the dealership early the following morning (work order initiated at 8:21AM). I explained the situation again, and was told that they'd perform a complimentary diagnostic test to determine the issue. The service advisor listed "Safety Recall - Driver Front Airbag Inflator May Rupture" [I did notify them that the warning light indicated it was the passenger side airbag]. At 9:00 AM I received a text message "To review the inspection and approve the recommendations": CUSTOMER STATES SERVICE AIRBAG MESSAGE CHECK AND ADVISE [Other]: DIAG, NEED 1.5HR DIAG TIME TO TEST CIRCUITS RELATED TO PASSENGER AIR BAG FOR CODE B0021 PASSENGER SEAT SIDE AIR BAD DEPLOYMENT LOOP. (NEED TOI REMOVE SEAT…”

“The Service Air Bags indicator has been on for 3 years and I have tried to get this taken care of with Buick, East Side Madison as I have indicated on another complaint form December 06 2024 NHTSA ID Number: 11629225. Now, today my daughter tried to open the door and the car's electrical system went haywire and would not let her out. I had to manually get a key to unlock the door. The electrical system is now not functioning correctly. A relative just had the same thing happen, couldn't get out of her car, the car started on fire and she couldn't get out and was burned alive. I would like the manufacture to repurchase this car as soon as possible. It is not safe and I am afraid someone is going to get killed in this car if it is not taken off the road. Please let me know if we can get this done without lawyers involved. Thank you. [XXX]”
