NHTSA — Service Brakes, Hydraulic: Fluid Problems

CarComplaints.com Notes: The 2005 Ion still had power steering issues and a defective ignition switch leftover from previous model years, but hey – at least Saturn improved some of its safety rating to marginal, right? Baby steps.

If you had to buy a Saturn Ion – and I would question why anyone would even consider it – I suppose the 2005 could be considered the best of a bad bunch? I mean, GM did finally get rid of that awful VTi transmission, and both the power steering problems and ignition switch defect that plagued owners were recalled. The problem is they waited 10 years to recall the ignition and let over 30,000 warranty claims get filed before they bothered to fix the power steering. So you kind of have to wonder, is GM making these fixes to keep owners safe or just to keep government lawyers from taking all their money? You be the judge.

2005 Saturn Ion Owner Comments

problem #1

Feb 082006

Ion 4-cyl

  • Manual transmission
  • 7,700 miles


I was driving my 2005 Saturn ion2 and the brakes totally failed when I depressed the clutch on my 5 speed transmission. After taking it in for service the mechanic told me that the slave cylinder was leaking and allowed air into the brake system because the brakes and clutch have a shared hydraulic fluid reservoir. I couldn't downshift because the clutch failed and I couldn't brake because the brakes failed. The warning system failed because there was still some fluid in the shared reservoir. The warning light goes on when the system is out of fluid not when it is running low. Scary stuff... I could have been killed or killed others. Lucky for me I was not going highway speeds and/or on a busy street. I was able to use the emergency brake to stop...
