I'm sending the GT in this week for a few issues. It has 31K on the OD and climbing quickly. About 1000-1500 a month, i.e. warranty will be up very soon.
- Spark knock issues. With 89 Octane I get part throttle ping. With 91 or higher octane, I get a ping at full throttle when it shifts to the next gear. Is this common? According to the owners manual, it's supposed to run on 97 octane. Any thoughts? I've heard from others that the dealer will say that this is normal. That's not acceptable to me. Spark knock severly limits the engine's life.
- On full throttle accelleration it loses power between 3800 to 4200 rpms and then "kicks" back in. It's more of a 15-20 hp loss in that rpm range and is consistant and it does it in all gears. Especially noticeable in second and third. It is not missing. Has anybody experienced this?
- Squeeking coming from the front left side when backing up while cold. It's not brake related. The sound doesn't change when the brakes are applied. I do have alignment issues on the front left, which may be related to this. The outside of the tire is wearing bad. No feathering. Just wear. Bad wheel bearing?
- Squeeking in the back end. I pulled the wheel off the left rear side while on the lift. There is a "anti-roll" shock that looks like it's plastic cover is rubbing on itself. I guess you would call it the piston for the shock. It goes from the axle to the body horizontally. What the heck is the name of that thing? I know what it does, just don't know what it's called.
- Don't have the owner's manual on me right now, so I thought I would toss it out. What is the torque required for tightening the lug nuts?
Thanks for any comments or suggestions you can provide.
