However, on my 2010 GL450 148k/mileage (no warranty) it shows
1- SRS Front right malfunction
2. Auxiliary battery malfunction (which came on 4 days later)
I'm thinking about removing both the main and aux battery to see if the signs are removed prior to me taking it to the dealer & spending money.
I tried wiggling all 7 seat belts inserts and dusting with moderate compressed air-- no luck.

You can get those seat belts rebuilt. There's a vendor on here Safety Restore that will do it. I think when I called them up about a seat belt that that wouldn't extend, they said it was $65 to rebuild them. OEM was like $800 and online was about $60-$100 for used ones on eBay. I managed to take all trim off to get at the seat belt mechanism and was able to blow it off and it started working again so I haven't actually had to use them. When I used a scanner on mine, no codes came up because it was a mechanical problem.
