Long time listener, first time caller. The patient: a 2005 Saturn Relay FWD3 with 151K miles, GM 3.5L V6 and 4-speed automatic. I am the fifth owner and this is our grocery getter and general abuse vehicle. I’m the longest owner – 4 years and about 55K of those 151K miles have been in my garage. I can’t comment on how well it was cared for from year 2 to year 6, but I have done everything by the book since 96K miles.

The Saturn developed a rough idle of sorts about a year ago. I swapped out the spark plugs, changed the fuel filter, and flushed the fuel injection. The car continues to idle rough. No CEL and no CEL history.

  • Garrett The only way to send a message is to pull out of the transaction when the fee is disclosed unless the dealer pays for it...or just walk out regardless.If this happens enough, eventually someone will get the message.
  • Sgeffe I pay for the Remote and Security HondaLink stuff (remote functions from a phone app; accident notification, etc.), at roughly $200/yr. That’s value-added stuff. (A nice addition is that I can enable the crash-notification on ANY Honda vehicle to which I pair my phone if I wish, as long as the vehicle supports it.) I can cancel this stuff at any time, though! It looks like you CAN’T with Mary’s Folly!Typical GM! 🙄
  • Jkross22 Just another reason to pick something other than a GM product. They'll be back at the government trough soon enough.
  • Corey Lewis I don't know a single GM owner who pays for OnStar. None.
