2024 CADILLAC ESCALADE Electrical System Problems

Component/System Involved: Engine / Powertrain and Vehicle Electronic Control Systems, including Serial Data Gateway Module Description of Failure: While driving at highway speed (approximately 60 mph), the vehicle experienced a sudden and complete loss of propulsion without warning. Engine power was lost while traveling on an interstate, forcing me to pull onto the shoulder without propulsion. The loss-of-power event occurred more than once during the same trip. The vehicle was towed to an authorized Cadillac dealership for inspection. Dealer diagnosis confirmed internal mechanical engine failure, including metal debris present in the engine oil, requiring full engine replacement. During diagnostic procedures, the dealership also identified electrical communication faults involving the serial data gateway module, including voltage fluctuation and wiring chafing within the vehicle harness. These faults caused loss-of-communication conditions between control modules and required repair. Safety Risk: The loss of propulsion occurred at highway speed with passengers present in the vehicle,...

Clicking that the dealer stated was normal. It was not loud knocking saying that is how the high flow fuel pump worked. Safety braking did not work at all. And there was a water intrusion in the trunk.

Coffee was spilled on center console while transferring cup from Starbucks employee to cup holder. Cup was overfilled and lid wasn’t on properly. Immediately the dash panel started flashing and the service transmission light came on. Drove around a parking lot for a few minutes and seemed okay to drive even with the instrument panel flashing. Had 90 mile drive and during drive message similar to slow down for gear shift popped up and “Service Shifter See Owner’s Manual” came up. When I went to exit freeway and was around 5 MPH the vehicle slammed to a stop. Then would not go into any other gear. As I called for tow driver I turned vehicle back on and was sitting when the vehicle started moving again without my control. I then drove it an additional 20 miles home staying above 20 MPH. Insane Cadillac would design a $120k vehicle with...

1.What component or system failed or malfunctioned, and is it available for inspection upon request? •The primary issue was with the vehicle’s software system, which was incompletely updated on 9/13/24. This has caused the safety features to malfunction. Additionally, the parking emergency brake engaged suddenly while I was driving. The vehicle is currently available for inspection upon request, as I have already reported the issue and requested immediate attention from the dealership. 2.How was your safety or the safety of others put at risk? My safety,, was severely put at risk when the parking emergency brake suddenly engaged while I was driving. This sudden braking caused me to sustain a strained neck and strained back. I was fortunate to avoid a more serious accident, but this malfunction was extremely dangerous. Additionally, the faulty safety features and the repeated and incorrect engagement of the OnStar emergency system have caused further distress...

I started my Escalade and 5 minutes later I lost power which as the entire vehicle had no power. So I left it alone for an hour or so in my garage and I started up again and this time didn’t loose power. Everything appeared normal and working again. Than the next day I started it up and I had this popup message SD card has been removed press ok to exit navigation (when no SD card was removed). I also noticed that my backup camera, grid lines, or augmented reality has also intermittently not working on days. It sometimes works as normal and sometimes it does not. The message shows Service Augmented Reality System. The following next day, while I’m cruising on the highway the Escalade shifted into neutral when I was going 75 mph and had no mechanical power. So I pulled over stoped the vehicle and shut...
