Electrical System · reported Oct 29, 2026
Vehicle stalled several times. Check engine light and many code came up. Crack sensors replaced. Veh still stalls. Dealer and independent dealer believes it might be cpu. All wires from cpu checked with no issue found. When veh stalls if you manipulate the wire veh will start and run with demished power and demished steering control. Rpm go to off mode. Has happened on highway and side road. Very scary with 3 kids in car on highway.... not able to resolve issue. Veh has a little less then 60k
Steering · reported Oct 25, 2026
Car was running great and mins later I get an error stating steering assist is reduced -Drive with care. Vehicles temperature gauge is stuck at cold and fans turn on after turning off the vehicle. I had the vehicle serviced at Dave White on Alexis Rd in Sylvania almost exactly a year ago for the same reason. Was told by the service manager the issue was a computer update and not the thermostat and proceeded to charge for the "update" no issues with vehicle until now.

It compromises my child’s safety tremendously by allowing the harness straps to slip off of her shoulders in event of a crash leading to a projected infant. Upon doing further research and posting in my moms group on facebook i’ve found countless reports dating back to 2023 where this magnetic chest clip is a terrible design and idea. Many consumers reported to the manufacturer and received multiple replacements and regretted buying the $360+ car seat. It needs recalled and removed IMMEDIATELY before they have…
