  • Don’t Blame CT6 Drivers Rolling Down the Road With Their Blinkers On


    A tiny number of 2019 Cadillac CT6 sedans may not cancel the turn signal after the steering wheel has returned to center.** It’s a defect that could turn you into that person. You know the one I’m talking about. The driver obliviously rolling down the road with their blinker on, leaving a swell of eye rolls in their wake. Don’t be that person. Have your signal switch replaced by Cadillac in this recall.

  • CT6 Recalled For Missing Bolts


    A seat belt isn't going to do you a whole lot of good when it's not properly attached to the car in the first place. That's what's happening with 131 Cadillac CTS sedans. Apparently someone on the assembly line forgot to install the front passenger seat belt anchor bolts. According to GM, the recalled cars were built during two days 07/21/2016 and 07/22/2016. My guess? That matches up with the same time Carl forgot to order more coffee for the break room. Way to go, Carl.
