Question about Chevrolet Corvette

4 Answers

I recently purchased a 2003 50th anniversary Corvette with 39,000 miles and electronic ride control that does not work. The switch between touring and sport makes no difference and the rtear shocks bottom out quite easily. There doesn't appear to be any leaks on the shocks. Could it be the sensors are out of alignment or is it more tuypically a more serious problem? If it does nneed more serious attention could I just switch to Bilstien shocks and scrap the electronic ride system as I'm not interested in spending thousands of dollars on the outragously priced components. Any help or ideas will be greatly appreciated. Thanks in advance, Randy

    If that's your idea of premium help please refund my money. I need someone whpo can address the issue and how to diagnos if it can be fixed not just say scrap the system without even addressing it.

    Thanks for the info on the system it was very interesting but I was really looking for someone who had actual experience withe the system as parts are very expensive for it. Check out gmpartshouse.com and you'll see it could cost over $6,000 grand in parts alone plus labor. I would still like to hear from someone who has worked on them and see what are things to look for and what are common problems and solutions.

Hello there the electronic ride system though the switch will change them from sport to touring. now try this (1),make sure there is power to the swith, (2) check and maybe replace the 4 sensors as these will play around also and come out of alighnment. (3) i have had a toyota sorer with that feature and when i chaned the switch from hard to soft i saw no diffrence (4) the best isea is go with the Bilstien shocks as the gas shock is inside the coil and will give way be performance and durability here is what they will look like http://img.photobucket.com/albums/v11/outlandish/Crutchfield/stage_one_rear2.jpg

I do not believe that there will be a magic answer for your problem! A full exam by the GM folks is necessary for this complex setup. These are not your fathers shocks!

Please read this article for details on how it works.

This is a complicated system with several failure points that cannot be fully diagnosed through this chat.

I believe that an aftermarket setup may benefit you, but I would also recommend a checkup from your local dealer.

Brian

Good luck!

I recommend going with your idea. Bilstien shocks are far superior compared to the automatic ride system garbage on so many levels I won't even go into it. Between cost savings and performance you will not be dissapointed I assure you.

    My first post was made from my gut. I never really was a big fan of computers getting involved in any portion of my driving experience. After researching the technology I must withdraw my first "shoot from the hip" opinion. Read this highly informative PDF about the technology in your ride:

    http://www.ee.washington.edu/research/me...



    After reading this and realizing the potential of this amazing technology any suggesting anything other than repairing this system would not only be wrong, But literally retarded. As the whole system is only a $1650 option on the Vette having it professionally repaired is the only logical option.

    As you stated that there are no leaks in the shocks(the most costly parts in the system) that leaves only relatively inexpensive sensors and switches and control unit remaining as the possible culprit/culprits in your problem.

    As you will read in this article this system is a revolution in suspension technology. It is capable of adjusting the responsiveness of the suspension 1000 times a second and that converts to approximately every 1 inch at 60MPH! That is SICK! The dampening fliud contained in the units can go from the consistancy of light oil to peanut but in 1 millisecond all controlled electromagnetically(no valves involved) By way of tiny iron beads in a solution of silicone.

    I once again admit I was totally wrong and in the dark about this technology. Having researched it I must reverse my proffesional opinion 180 degrees and strongly advise you to have this system diagnosed and repaired as it will bring performance, handling and above all your safety to a whole new level.

    Hope you find this information invaluable in whatever decision you make. You own a sick piece of machinery and it deserves to be maintained to it's optimum condition. The only other thing I could possible say was I wish that it was mine!

    What does the picture of an ATV 4-wheeler have to do with the suspension system on a Corvette? I guess it tells you that the after market shocks will be yellow.

    George Kohler Jul 21, 2008

    That last post had to do with a link to a picture that was supposed to show you what your Vette would look like. I clicked on it and saw a picture of a 4-wheeler with a yellow shock. WOW. Anyway, I just wanted to make it clear that the only recommendation any tech on this site can make about this situation without being banned is to have the electronic ride control professionally repaired, and in this situation it is actually the best solution. Techs on this site are not allowed to recommend removing or altering any devise or system in any vehicle or product that acts as a safety device. As your suspension system exponentialy increases the handling and saftey of your vehicle it would be a wrong decision to downgrade this system. I'm sure your not going to go to walmart and put the cheapest tires you can find on your Vette. Why would you want to down grade it with shocks of antique engineering compared to what's in your car already. When you do eventually get it checked out the bill will not be that bad if the shocks themselves do not have to be replaced. The overall physics of standard shock have not changed since they were invented. Your suspension system is leading edge technology. Have it fixed man.

Here is a link talking about one kit for your vette. I probably would just scrap it and go to after market myself. It's a cool option. If it was working. You can always sell the parts or keep them in case you ever decide to go back.
Good luck and please keep me updated.
Thanks,
Lee

1993 anniversary corvette problems


Have you had a water pump replaced lately? If so water may have got to the distributor and causing the car to act that way. When it gets hot is shuts down. Sometimes it will take awhile to restart.They put the distributor right in behind the water pump and any water leaks from pump will 99% of the time fry the distributor, if not caught.

My 2004 Rx330 is showing maintenance required at 65,500 miles. I purchased the car used at 39,000 miles all I have done is changed the oil every 5,000 miles. What do you think the maintenance requirement...


a major service is due at 60000 miles. the light is just a reminder that maintenance is due. is it the message on the nav screen or the one on the dash cluster? if you want to turn it of, hold the trip/od button in while turning the ignition on, keep your foot off the brake, dont start the car. you will see dashes flashing where the od shows miles, hold until its done flashing. and the lite on the dash cluster will go out. it will come back on after 5000 miles. you can go online to lexus.com to review what the services are and what they involve.

More than likely the heater valve is stuck open. You can usually purchase them from the local parts house. As far as the ride most of these cars ride this way. You can update the suspension with newer designs and shocks to allow a softer ride and can even get suspension that is adjustable allowing you to set the ride and performance yourself to your liking. Air suspension is probably also available to allow maximum soft ride.
