As it turns out, the lack of microchips is not only having a negative impact on new GM vehicle shoppers, but to current GM vehicle owners as well. We’ve been well aware of the fact that the ongoing semiconductor microchip shortage has been wreaking havoc on the automotive industry, stifling automakers’ ability to produce vehicles which has resulted in a high demand for both new and used models. Experts have warned that it could last into 2023, though in late September, General Motors president Mark Reuss stated that the global microchip supply is expected to begin to stabilize, albeit at a level lower than desired.
According to first-hand experiences sent into us by our readers, faulty ECUs are causing a major headache for existing GM customers. Service advisors have informed customers that the necessary parts have been on back order for months, leaving vehicles inoperable as they wait for parts to arrive.
I’ve been waiting on an ECU for my Silverado for the last 8 weeks. My truck is not drivable because of this. Even worse is that nobody knows (dealer, Chevy customer service, etc.) how much longer it will be.

The computer that handles the tire pressure stuff needs to be replaced in my CT5. Dealer tells me that they ordered the part, but it’s on back order and has been that way for the last 3 months. Dealer and Cadillac reps don’t know when the part will be available. I guess I’ll drive with the tire pressure warning message going off every time I drive the car. How’s that for luxury?

No ECUs in stock for the last 9 weeks and none expected until the end of the year. I guess I have no other choice than to keep paying the note on my Traverse which is now a big brick sitting in my driveway. Dealer has no loaners. GM needs to step up and do something. I would take a Spark loaner so long as I have transportation.

With GM’s build-shy strategy soaking up the majority of microchips as they become available, it’s tough to say when the parts will become available. Our sympathies go out to customers who have paid – or are continuing to pay for – their GM vehicle that is effectively inoperable.
Fortunately, the industry is at least attempting to work towards solutions, with microchip companies suggesting that electric vehicles come equipped with silicon carbide or gallium nitride components, rather than the traditional silicon chips widely used now. In addition, General Motors recently signed a deal with Hertz to provide more loaner cars to dealerships.
