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. …”
NHTSA complaint #11210303, filed 2019-05, 115,000 miles“I have a p0420 code on my 2014 Buick Enclave for about a year now.

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. …”
