Drivetrain Electronic Gremlins - 2014 Mercedes-Benz CLA250 Extended-Term Road Test

2014 Mercedes-Benz CLA250: Drivetrain Electronic Gremlins

May possibly 16, 2014

The day following our long-term 2014 Mercedes-Benz CLA250 insisted its nav screen was being stolen, I discovered yet another (and surely far more alarming) quirk.

Here’;s what it did.

I was driving in the ebb and flow of freeway targeted traffic, alternately employing the transmission’;s manual and automatic modes as usual. At a single point, I returned to the throttle to uncover no forward progress at all. I glanced down and saw that the transmission was now in Neutral. It did this of its personal accord.

I nudged the selector down to re-select Drive, and resumed driving. At this point I noticed an alert had flashed up in the instrument cluster: “Pre-Secure Functions Limited. See Owner’;s Manual.”

The alert then blinked away, to be replaced by the a single you see in the lead shot: “Cruise Control Inoperative.” And it was. The cruise was no longer functional.

A crucial cycle performed later returned it to its normal self.

This vehicle has concerns.

2014 Mercedes-Benz CLA250: Anti-Theft Protection Gremlins

Could 15, 2014

I began up our extended-term 2014 Mercedes-Benz CLA250 the other day, plugged in my telephone to charge it, and when I looked up I saw on the car’;s central screen: “Anti-theft protection activated. Service necessary.”

Oh, actually?

This warning apparently applied only to the multimedia screen, as the automobile ran and drove as regular. Nevertheless, I had no access to any of the controls for which this screen provides the interface: radio, navigation, and so forth.

Turning it off and on again turned up the identical outcome. A essential cycle did the trick, returning it to its usual self, and the glitch hasn’;t returned in the meantime.
