Greetings! Might someone have some insights for me? They would be much\nappreciated!\n\nI’m the original owner of a 1997 Saturn SL2 with about 54K miles on\nit. For a number of years I have had a problem with a rumbling sound\nunder the front of the car, which I’m not sure how to fully describe,\nbut which makes the car very unpleasant to drive as the sound\ncontinually comes and goes and is quite loud. The car runs very rough\nand at 25 mph or below, there is a deep persistent rumble under the\nfront of the car. It comes and goes based on the tilt of the vehicle,\nyet this is not always predictable. It is VERY common and evident\nwhen driving downhill; not as much on the flat or uphill, but it does\noccur then as well. I can be coasting on a flat road with my foot on\nneither the brake nor the accelerator and it makes the noise. The\nsteering wheel is not much affected by the rumble; I don't feel\nexcessive vibration there, or so it seems. The noise appears to have\ngotten worse when I got new tires last fall, which might just be\ncoincidence. At faster speeds the noise diminishes and, on the\nhighway, the car still runs like a champ -\- and I’m thinking the road\nnoise drowns out the rumble so it only seems like it less?\n\nWhat else might be helpful for folks to know? I have had oil changes\nroughly every 2,500 miles from Day 1 (Aprils and Novembers). I just\nhad a motor mount replaced (the transmission one if I have that\ncorrect). The one on the top left of the engine was replaced a while\nago and still passes whatever test they use. I’m on my fourth\ncatalytic converter, this one being an original Saturn ($$$) as the\naftermarkets pooped out after a year each time (I am accustomed to\nexhaust system problems in all my prior vehicles due to my low annual\nmileage, so this was no big surprise to me.) I've heard something\nabout Saturn engines getting out of balance over time and, while the\ncar is safe to drive, at some point the noise will get too annoying\nand it’ll be time for a new car? Naively, I keep thinking a car\nshould function well for more than 54K miles? But perhaps in Saturns\n“It’s not the mileage -\- it’s the years?” (apologies to Indiana\nJones).\n\nI just thought I’d run this past some Saturn folks to see if there\nwere some possibilities I wasn't considering in trying to solve this\nproblem, because, while I would like to keep the car longer, I think\nI'm about ready to trade away the noise problem for a new 2011/2012\nvehicle. Thanks much!
