I have a 2009 Dodge Journey that is just under 2 years old (we bought it new off the lot). it has had some mechanical issues… But the dealership has done well in servicing it under warranty. But they just told me that as part of their 23-point safety/maintainence inspection the mechanic found that the throttle body has carbon buildup that should be cleaned out. The mechanic found this while checking the air filter and the intake hose to the throttle body.
The car has low miles and the maintainence clerk says if I don’t do this service then it would void my warranty if carbon fell into the engine via the throttle intake and caused damage. It seems kind of fishy that he could see this without taking the throttle body apart. And it would cost about $190 for the service.
Is this just an unnecessary sales push… Like undercoating a car at the dealership or some other nice to have tune-up point that I really don’t need to worry about?
