Intermittent Problem: After a successful drive, restart, ~all warning lights illuminate, power steering fails, top will not reposition. Drive ~100yds PS restored, most warning lights turn off. After it sets for awhile like a day, restart, runs great, no warning lights, subsequent restart with same scenario. Dealer has been unable to resolve this significant issue.

 

My only suggestion would be to have the dealer thoroughly check all modules, connectors and wiring related to the body control, power steering and convertible top systems. An intermittent electrical fault can be tricky to pin down. Hope they're able to resolve it soon so you can enjoy trouble-free driving again!

 

Are you the original owner? Has the car been in an accident?

 

Ok so this goes to the normal check list from the first thing to do:

First and always first regarding any electrical issue that has more than a simple DTC is to confirm by way of a LOAD TEST the batteries state of health.
Then check all the battery cable for continuity both at the battery terminals and especially the ground at the body or chassis and lastly the Starter.
Please do not assume because of the age of the battery or you think the battery is ok!

If the battery passes, then:

Directly connecting to the OBDII diagnostic connector (no blue tooth) look for and note any and all DTC.
Then move on to the I/M Monitors and see their state of readiness or fault?

You can then either report back or if you do not have this capability that you should have your Mazda checked out at either a service shop that employes an automotive technician or a dealer.


BTW ...the question about if you are the original owner or if the Mazda was in an accident is irrelevant at this stage of diagnostic Q&A . I know where that would take this thread and really it irrelevant and would not be asked at either a dealer or independent service shop. We don't care!
