GM Launches BrightDrop Zevo 600 Satisfaction Program For Corroding High-Voltage Connector

GM has begun a Customer Satisfaction Program for certain BrightDrop Zevo 600 (or EV600) models to address an issue related to the high-voltage connector for the delivery van’s battery pack.
The problem: in affected vehicles, the high-voltage connector may corrode and allow water to leak into the van’s high-voltage battery pack. If this condition occurs, a malfunction indicator light (MIL) will appear on the vehicle’s driver information to display to alert the operator of the issue.
The hazards: GM did not say what potential problems this condition could lead to, however it seems likely this problem could result in further damage to the high-voltage connector and/or battery pack if left unaddressed.
The fix: GM will instruct service technicians to apply additional AC Delco RTV Engine Sealant to the high-voltage connector, which should help to prevent corrosion and prevent water from leaking into the connector/battery.
Affected components: high voltage connector, lithium-ion battery pack.
Affected vehicles:
- BrightDrop Zevo 600 (formerly known as EV600)
- GMC Hummer EV
Number of affected vehicles: roughly 424 vehicles are believed to be affected by this particular issue across both the GMC Hummer EV and BrightDrop Zevo 600/EV600 model lines.
Owners should: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer. Owners that are unsure whether or not their vehicle is affected by this Customer Satisfaction Program can reach out to GM directly with any questions or concerns they may have using the Service Update number and contact information included below. To be clear, this problem is not being addressed through a Product Safety Recall and is instead only a Customer Satisfaction Program.

Not enough Real World Testing! It’s just beginning for GM!! More to follow!
Hummer was tested for over a year and the Ultium platform was completed long before that. Sounds more like a supplier issue.
Yes, but they are using pouch batteries.
I bet that “M S Watchdog” is correct, and we’re going to be seeing more articles about problems in the future with Ultium.
When will NHTSA realize that a 9 ton pickup truck (Hummer EV) may require another look at the side impact safety of a vehicle. Should they add a Honda Civic to the bed of current pickups to perform the test because that’s the weight comparison when you add the battery. We have seen a small lithium battery explode so should we add Incendiary Devices for the test also?
*4.5 tons
First, it’s better not to hit things to begin with. That’s why there’s the US and EU mandates for autonomous emergency braking and lane departure warning. The EU is testing more complex situations too, like turns in front.
Second, IIHS has specifically increased their side impact crash test. There was an article about it yesterday.
Third, NHTSA has had regulations for over 15 years now that batteries don’t leak electrolyte, catch on fire, or pose a shock hazard during the mandated crash tests. This was an issue with both the early EVs and hybrids, so it was already thought through.
wow, that problem didn’t take long to rear it’s head. The fix seems rather haphazard and half-assed, a glob of silicon sealant? Always good to know that a potentially major problem in a super-high profile vehicle is solved with a can of FlexSeal.
I believe Ford has the same issue with the mustang?
Dialectic grease.
I am sure this will just be one of many problems to follow. The new slogan for manufactures moving forward with EV car/truck will be, Buy this car/truck because it has the least amount of problems before u even drive it!
When manufacturing Short cuts take place to save costs the EV’s will start going up in flames
