Damn your suzuki dealers and service sucks. Got a 2018 GV ( last of the 3G models sold here) that came in 6 months shy of the end if its extended 5 year powertrain factory warranty with a faulty abs unit, found during annual WOF check. Suzuki NZ are replacing it no questions asked.In case the special oil doesn't work Suzuki Technical will prepare a special running in additive otherwise known as sawdust.
My dealer recently referred my intermittent gearshift problem to Suzuki techs - their response was to "authorise" further investigation provided the customer agreed to pay. This is on a vehicle 12 months old!
How Suzuki achieve excellent customer service ratings is bewildering.
Good luck and persevere.
