2016 Mazda MAZDA6 Engine problems

The vehicle exhibits dangerous electronic malfunctions. A licensed technician (MV-113255) has confirmed a sporadic unintended acceleration defect where the cruise control 'decrease' button causes the vehicle to increase speed. Additionally, the vehicle repeatedly enters 'Limp Mode' in active traffic, causing a violent jerk and a total loss of acceleration while displaying a 'Smart City Brake Support' (SCBS) failure on the dashboard. An independent inspection also documented gross mechanical neglect, including loose battery terminals and a loose transmission bellhousing bolt, which may contribute to these intermittent electrical/safety failures.

Dealer said nothing to worry about, but I finally took it to autozone who said code was stored as misfire on cylinder 4. Dealer is looking at it now, but always dismissed it before. Now that I know it has to due with a cylinder - why didn't they investigate further? Of course my car is about 2 months out of warranty and 17oo miles as of today.

This car has serious problems. I have approached mazda with numerous service complaints and they refuse to fix.
