Suspect corrosion


Asked by Feb 06, 2019 at 12:32 PM about the 2013 Buick Verano

Question type: Maintenance & Repair

Our 2013 Buick Verano with 30,000 miles started displaying a couple error
messages on the dashboard display about a year ago.  "Side Detection" and
"Airbag Service" were a constant annoyance. My wife and I are in our '70's
and we just ignored it.  Car ran fine.  This morning shortly after driving on
some rain-soaked streets other messages appeared and the gauges (Tach,
Speedometer, Gas, Temp) stopped working too.   I strongly suspect a
plug/connector corrosion problem.  Where would be the connector for the
gauges?  I am hoping to find a blue-green gob that I can clean-up.

I too am in my seventies and I can tell you that cars don't work like that any more. When something goes out and the fault isn't fixed, it can affect other things: it's just how computerized cars work today. The problem might be in the gauge cluster, but it might be several things have just gone out and if you don't address them, you might lose your car. Have a reliable mechanic check this out. It might be a simple fix tht could save you a great expense in the future.

Thanks for the prompt reply. I went out and braved the weather and found nothing under the hood, both top and bottom. I checked the firewall area both inside and out - all appeared normal. All connections were solid. I did find that the gauges pass the POST (Power On Self Test) and then die. Time to stop mucking around before I break something. Decision time. ~Lee


Ed92626, I took my Verano to the dealer this morning. All my sensor and display problems were caused by a defective REAR SIDE DETECTION MODULE. The module was dragging down all the other warning modules and was gradually getting worse. The wrench turner told me it would have eventually cause even more failures and possibly BIG expen$ive repairs. The labor and two sensors came to $1,100.00. Car is once again perfect. Thank you for your sage advice; following it got me rolling again and saved me money in the long run. You are a real asset to this site. ~Lee
