They stated car needed oil change and tune up. On 11/17/2023 while in the line at a drive through lights came on again and car died in drive thru. Car was towed back to Firestone. Firestone said it was pulling codes they didn't know and the car needed to go a Buick dealer. Towed car to Bob Brown Buick on 11/24/2023 Bob brown said car just needed a battery. After one hour the car lights popped on again and car died in the middle of the street. Towed car back to Bob brown another diagnosis was completed and was told I needed a catalyst converter.

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.

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!

I have a P0420 code on my 2014 Buick Enclave for about a year now. Almost everything related to engine performance was replaced because no one could believe that the catalytic converter went bad - even at the dealership - on a 4 year old car where the aftermarket catalytic converter has a 5 year warranty. I spent over $2,000 so far replacing one thing after another at the dealership's advice because they did not even know the reason for the fault. Now I know it is the catalytic converter because the exhaust started smelling bad whenever the car is running. GM/Buick should investigate why its catalytic converters are failing and fork the bill on fixing it.
