Default Steering Column Lock Problems

Looks like this problem has returned. I've had 2 recalls done on my 99 Coupe with just 37,400 miles. Last recall was done just 2500 miles ago. Same local dealer doesn't want to help unless I'm willing to pay. I've contacted GM Customer Relations, any other suggestions ? I don't feel I should have to pay for this well known C5 problem that has been ongoing. Thanks in advance for any help you might give me.

It will be impossible to find any dealer who will cover this under warranty. Have your battery tested as low battery voltage can cause this problem. Many owners have had a LMC5 installed to correct this problem.

On a 25 year old car I have to side with the dealer on this known issue or not. Our harmonic balancers have "known issue", my C7 had known transmission issues along with a leather dash that was separating.All known issues but if out of warranty you are out of luck. My aftermarket warranty covered the 4000.00 tranny repair.

First, you need to understand that GM is a car sales company. Period, They offer parts, service and warranty services as incentives in order to sell cars. If these things were not necessary in order to sell cars, they would not offer them. They are viewed as sales tools.

The only angle, IMHO, that may persuade GM to assist with an antique vehicle would be if you can demonstrate to them what a good customer you have been over the years. For instance, if you can make a compelling case for them to make not a warranty decision, but a business decision such as the following:
I currently drive a 2022 Silverado. My wife drives a 2021 Cadillac. Over the years I've owned a 2018 Escalade, a 2015 Camaro, etc., etc., and, the love of my life, a 1999 Corvette for sunny weekends. As you must be aware, the steering column lock problem has never been completely resolved on these wonderful vehicles. I'm asking for you to make a business decision to provide some assistance with my Corvette. Your response will figure prominently in my decision to replace my Silvrado (the lease is up in less than a year) with another Silverado, or if my family will cease to be a General Motors family. Let's be clear, I'm not asking you for warranty assistance on a decades old vehicle. I'm asking you to make a business decision to retain my family as loyal GM customers.

Best of luck!

Just do the LMC5 repair. It's a really cheap fix and you're done. I went to repair mine and found it had already been done. I was trying to frontrun the problem. Don't want to be stuck somewhere! It's super easy too.

So I'm reading some say to install the LMC5 or the Original Bypass Module. Is one better than the other and is one easier to install than the other ? Price wise they look to be about the same.

I agree that this is the best approach. It appears that this address the various issues on the bulk of vehicles. Be aware, however that there have been recent reports that the LMC5 modules available on both Amazon and ebay have been found to be counterfeit.

Purchase from a trusted source!

The recommended RC (Reserve Capacity) on the battery is 120. This is supposedly an important factor is keeping the column lock happy. I couldn't find a 75 series battery with a 120 RC. If you go to a 78 series battery ( one size up) you can get one. It will fit the battery tray and still bolt down but it does fill the entire tray.

I have the factory fix and.no issues. The car is 21 years old and has 321k miles.
