2015 Chevrolet Impala Lt Vin# [redacted] infotainment center & Steering went out 2 years ago Greg Chevrolet in savannah MO told me $800 for infotainment unit only car only had diag code B127E car only 3 years old at the time still does not work! Earlier this year driving to work 70 mph steering goes out I almost hit car next to me had to muscle the car to side of road then warning light popped up to service power steering!! Very dangerous for me and any cars on the road with this car! Had mechanic do diagnostic it had 20 error codes he reset them car worked 1 day same thing over again. We paid the car off but still can't drive it and can't afford wheel bearing a new rack etc this car has now been parked in garage for fear of driving with no steering or info center and the wheel was mounted with tire backwards from dealership when we bought the car!

Blind side collision monitor is not functioning properly due to faulty design which allows moisture to get into cabin where the monitor is installed. Causing the collision feature not to function properly and "service side collision" msg to show on the dashboard. I had this issue before and had it repaired by the dealer on 03/2019. The problem has since returned. But this time it's caused the functions on the dashboard ( gas, h/c and speed meters, digital monitor screen etc) to stop working where I can't tell if I have gas or my driving speed or anything associated with the dashboard info system, it blacks out. And now the alert light on the door mirrors continuously stay on even when there's no car on the side of my vehicle and even when the car is turned off. I took it back to the dealership and have been told that the collision monitor sensors AGAIN need to be replaced.
Complete loss of power assist steering resulting in difficulty in steering the vehicle at any speed. DIC messages indicate: loss of power steering, drive with caution, service traction control, and service ABS. ABS and traction control warning lights remain on and illuminated while driving. These indicators occur each time the vehicle is restarted. This problem originally started about two and a half months ago, and the power steering loss, for a while, was intermittent until recently. The vehicle has not been inspected been inspected by mechanics to date. I have researched hundreds of Impalas online with the same problem with a majority of them remaining unresolved and no manufacturer recall being issued. The vehicle mileage is currently 31, 104 miles and is not driven often because of the problem and the fact that I own two other vehicles.
The blind sensor indicators are defective. The right side stays on but the the left side worked accordingly. Without warning the indicator on the left also stopped working. GM is well aware of the issue but will only fix the issue if it happens within a warranty timeframe. The initial issue with mine happened while driving in a winter storm with slushy roads. The sensors that stays illuminated isn't as much as a safety issue as the one that was lighting up as expected then stopped without warning. This item should be a full recall not a fix it if it breaks scenario. Mine stopped working within my warranty timeframe but because I was a secondary purchaser, I had no way of knowing that waiting until my next oil change would cause me to be stuck with $800 in repairs because GM refused to recall a safety issue item they are well aware of.
