2023 CHEVROLET COLORADO Lane Departure Problems

Blind spot warning stopped working Mirror controls (unable to safely change lanes) Window controls stopped working Chevrolet has a TSB for similar but not exactly this situation, dealer won't look at it outside of warranty without charge.

1. Other: Turn signal - when turning right with the signal activated, once you straighten the wheel, the turn signal stalk will reset to the middle but will activate the left turn signal. 2. Adaptive cruise control - For no reason the brakes will activate, there is no vehicle in front and the windshield is clean. 3. Blind spot warning - These BSW indicators will go off at random with no vehicles beside mine. This occurs more at night, but does happen during the day. When this happens at night the yellow indicator is so bright that you cannot even see what might (or is not) in your blind spot. This faulty indicator is going to get someone hurt as other drivers with the same issue might over correct.

Side object sensors go off frequently when no vehicles are there on both sides of vehicle. Additionally when passing vehicles the side object sensors only detect vehicles about 40% of the time. The side object sensors will double flash when no vehicles are there and fight me when changing lanes when lane assist is on. I have video of the false alerts and non detection incidents.

Signal on to turn right. Turn completed and left signal turned on by itself. Driving on freeway, cruise set 65mph, lane keep assist turns off without warning. Veered into shoulder unexpectedly.

Blind spot intermittently turns on despite no vehicle in blind spot or any where near. This still occurs even though the dealership updated the firmware and said it was fixed.

Within in the two weeks of owning my truck the forward collision warning has alerted and forcefully slammed my breaks to a complete stop. One going 75 mph on the highway and once during normal in town driving. I have deactivated the system ever since. I did make my dealership aware but they just said they aren't aware of any issues. The driver side blind spot monitor constantly gives ghost alerts when it is dark.

The blind spot warning will light up on the passenger side randomly when no other vehicle is present. If changing lanes while this occurs the vehicle will try to force you back into the lane you are trying to depart from. This false warning could potentially result in an accident. The dealership has so far been unable to recreate the problem, but this was only attempted once. The dealership did state that this is not the first time this issue has been brought to their attention. I have also found numerous complaints online regarding the exact same problem. No other warning lights have appeared. The vehicle has not been inspected by the manufacturer or others besides the dealership.

BSWS does not function correctly. It will light up warning in mirrors when ther is no vehicle approaching. Then many times both mirror warning lights will be on for a long time even an on empty road, such as a drive way. This condition is very dangerous for the driver as he gets a warning of a vhicle in his blind spot when none is there or no warning when one is there. Have taken back to dealer and no resolving of this very dangerous condition.

within 24 hours or purchasing this brand new truck (5 miles on it) sensor issues began and slowly escalated from a service door latch system error to auto braking engagement for absolutely no reason at 35-40 mph and side mirror warning sensors turning and staying on causing all windows not to move. There have been other issues as well however those are the most alarming as they directly effect the safety of the driver and passengers and the inappropriate auto braking engagement could cause injury or death to the trucks occupants as well as drivers around them. This problem is discussed widely on Chevy Colorado forums as many owners are experiencing with the 2023! The truck has been in the dealership with attempts to repair 4 times, the third attempt took a month and within 2 hours of pickup it started again. 4th attempt, 20 mins after pickup auto collision system was going off as usual. Now I have errors on the dash to service the driver assist system and the side warning mirror lights no longer work. Someone is going to get killed. There are forum conversations where people are driving on the highway going 80 and the brakes engaged for no reason. GM is well aware of all of the issues with my vehicle as I have been in communication as well as the dealership. The dealership told me another person bought a similar truck and had / has the same problem. GM refuses to purchase this truck back even though they know this is unsafe and want me to continue to try to have it fixed. I have a ton of documents to support this but when I click to upload nothing happens to allow files to be attached. I'm more than happy to share them, they include repair orders, conversation with the dealer and GM, screen shots of errors etc. One document includes a text message from the dealer stating there is a bunch (I know it to be 2 pages) of history of lost communication code errors that would have occurred at the manufacturer yet they released it for sale anyway

The contact owns a 2023 Chevrolet Colorado. The contact stated that the blind spot mirrors intermittently failed to operate as needed. The vehicle was taken to a dealer where the driver’s side door sensor was replaced; however, the failure persisted. The dealer performed several additional repairs to the vehicle however, the failure was not corrected. The manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 3,000.

Mileage: 3,000

While driving the blindside indicators will come on when nothing is there. The window switches and door lock button on the driver side door will not work when the blindside indicators are on. Also the light on the door lock button turns on and off randomly when the indicators are on with nothing there. The doorlock button on the front driver side door didn't work when the truck was in park. Haven't noticed if the windows and doorlock button don't work when the indicators are not on. Andriod Auto wouldn't connect wireless and has been till now.

After starting my 2023 chevy colorado trail boss and letting it idle for several minutes, my blind spot monitors will both illuminate on each rear view mirror for no apparent reason. When this occurs, I am unable to roll my windows down. Also, this issue occurs at random times while driving, seemingly occurring more when braking or decelerating. This issue renders my blind spot monitoring system unreliable to hard to trust. My truck also tells sometimes to service my door latch system when these issues occur. Although these issues seem to resolve on there own, they continue to persist everytime the vehicle is needed or driven. My blind spot monitors, in general, will also illuminate when trees or traffic signs etc. come into view. Also sometimes rendering my window switches useless.

The blind spot warning in the mirrors is on most of the time for no reason, usually when decelerating, when accelerator is touched the blind spot warning will go out. When the blind spot warning is on the windows will work, very dangerous situation. The service door latch system warning will appear once in a while as well. If you look on the many Chevrolet forums, you find hundreds having the same issues.

2 incidents. 1. The blind spot indication (driver side) gives false readings sometimes. Will light up at various times in clear weather with no vehicle next to me. Sensors checked and were clean. 2. The vehicle had a dead battery. It was jumped by roadside assistance. When started, the vehicle had a check engine light. I called Onstar (hands free function built in) to diagnose the problem while driving to charge the battery. Onstar told me what it said and indicated I should take it to the dealer. When I attempted to merge onto OK-51 the vehicle suddenly stopped accelerating without warning causing me to nearly miss another vehicle while merging. When I looked down at the IP, a message came up saying vehicle limited to 62 mph. I wasn’t previously warned or told by Onstar that this would happen (I was still talking to Onstar when it happened and the customer service representative sounded surprised). I did not collide with the vehicle but the other vehicle had to take evasive maneuvers to avoid my unintentional slow merge.
