Multiple lights on including Power steering failure, brake system failure and other electrical system failures. The failure caused issues with the power steering, and brakes. Another person has the same issue under NHTSA and the dealer had no idea how to fixed it. Also the engine light and traction control light are are. Dealer says I need to take out my auto start that has been in there 3 years.

Update from Mar 22, 2018: Had minor body work done 5 months ago. The auto body shop looked at it and saw there was no metal to metal connection with the ground wire because of paint on a bolt. They removed the paint and thankfully no more issues. And thankfully I didn't take out my auto start because I knew that wasn't the issue.

Bought new and after a few hundred miles the oil change reminder light would come on. Reset it but within 10 miles of driving it would come on again. Seat belt chime for passenger seat would chime even when nobody sitting there. Display would shut off while driving, sometimes at startup all radio presets would be gone, nav system really worthless. Can't look for gas stations, hotels or anything while driving. You have to pull off road in order to use it. A/C never got cold. There are other complaints but I can't think of them right now. As much as I paid for this, you'd think it would work properly. Oh, it was a CX5 Grand Touring model. Took it back to dealer and they keep saying nothings wrong! Just traded it in 3 months ago. Never will consider a Mazda again!
