That makes OnStar's role even more damning — they understand the problem, can't fix it, and don't even know their own system well enough to walk you through the workaround. Here's the complete final draft: The navigation system on my 2025 Chevrolet Equinox EV will silently change my set destination without notification or driver consent. I will enter a destination, and the system will reroute me to a different location — a ChargeAmerica charging station — without alerting me that it has done so. I only discover this has happened after I am already committed to the new route, potentially in an unfamiliar or unsafe area. This behavior appears to be driven by a pre-configured commercial partnership between GM and ChargeAmerica, prioritizing that network regardless of its proximity to other available charging options or the driver's intended route. The system cannot be overridden or disabled by the owner. On one occasion this silent rerouting directed me approximately 40 miles in the opposite direction of my destination, bypassing closer charging options, leaving me critically low on charge and nearly requiring a tow. This has affected me on two separate occasions. I have had extensive discussions with OnStar regarding this issue. OnStar representatives confirmed that this behavior is occurring but stated they have no ability to fix it. They were also unable to direct me to the charging menu setting that enables routing to Tesla Superchargers — a workaround I had to locate myself. Additionally, some Tesla Supercharger locations are restricted to Tesla vehicles only, with no warning provided by the navigation system. I used my remaining range to reach one such station only to discover I could not charge there. The vehicle is available for inspection upon request. No warning lamps appeared. The system functioned as designed — the design itself is the safety hazard.

The vehicle lost acceleration/propulsion while traveling at highway speed on a major bridge with limited safe shoulder space. The vehicle suddenly stopped providing power needed to maintain speed in fast-moving traffic. Passengers included an infant, young child, and other family members. This created a serious safety risk because there was little room to safely pull over while traffic continued around the vehicle. The vehicle was towed to an authorized Chevrolet dealer and is available for inspection. The cause has not yet been confirmed. The vehicle has about 15,000 miles. Shortly after the lease began, the check engine light came on intermittently and then turned off the next time the vehicle was driven. There have also been prior concerns with unexpected automatic emergency braking behavior. This complaint is being filed because sudden loss of acceleration/propulsion at highway speed on a bridge creates a serious crash risk.

Almost every time I fill up with gas ( I use top tier like the manual states), once I start driving, it feels like it misfires or jerks. It will do it one/ two times and then it’s fine… until I fill up with gas again. It’s been doing this since I got the vehicle- no indicator lights on.

While driving my Equinoix EV I lost propulsion and the dashboard started flashing. I could coast to curb lane. When fully stopped I turned the car off and on again and propulsion resumed. I have taken it in to the dealership and they said they see no error message and I should continue driving to see if it reoccurs. They suggested I keep cloth to wipe off windshield where sensors are in case it was obscured. This happened in clear weather.

This complaint is to clarify and supplement a previous report. The issues began in August 2025, not September. Initially, the vehicle presented abnormal fuel range fluctuations, including while stationary, as well as intermittent “Key Missing” warnings while driving and display black spots. These issues were reported to dealerships and GM without resolution. Over time, the condition has progressively worsened, and additional symptoms have developed, including abnormal noises and, more recently, transmission hesitation during the initial gears, requiring me to reduce speed for the vehicle to respond properly. The escalation of these issues over time raises ongoing safety concerns.

My daughter was driving and she said the check engine light started blinking and the car slowed down immediately. She had to press the gas to get it into a gas station.

My car threw on the check engine light and a note flashed on the screen and car just slowed down immediately. I had to press on the brakes really hard to get it home and then the transmission wouldn’t go in reverse. I took it to the dealer and they couldn’t duplicate the problem but said the battery contacts weren’t tight.

Check engine light was on after just sitting in the snow for two days. Dealer is saying that it is a fuel injector and something with the gas. I hope this fixes it.
