2023 Chevrolet Colorado: check engine light

Filed Sep 21, 2026 · Brakes, Driver assistance · UT

After shifting to drive the vehicle had no brakes. A week or so earlier the check engine light came on. Messages on the screen said brake system failure along with other messages. Took to dealership, an update was installed. Last Wednesday engine light reappeared with the same messages but didn’t have time to return it to the dealership so parked it until today. Today was the brake failure. Returned to dealership, they replaced the battery and said the brake issue is fixed. I’m not convinced this fixed the issue and believe this could get someone seriously injured or killed.

Engine light came on. Fan ran high. Had it towed to the dealership. Has 39,000 miles on it. Needs a new upper radiator hose due to a defective hose. Apparently, after reading online, GM is aware of this issue. Now we have to pay the diagnostic fee and $850 for a new hose and a flush, as well as the tow bill! Now can’t get the part for a week or 8 days and then have to wait on the repair. This is unsatisfactory that there is a known problem and isn’t covered or hasn’t been a recall.

Since Friday, February 23rd 2026 when my 2023 Chevy Colorado first start blowing oil out of the oil pan. almost 5 qts total was lost when it arrived at the dealership. Truck was out of service from Friday until the following Wednesday, January 28th. The truck was picked up and taken on a drive out to (January 29th, 2026) Waverly, KS from my hometown of Prairie Village, KS about 70 miles. On the way back home the truck went into safe mode at highway speeds. Lost all acceleration and barely made it off the side of the road before getting hit. Truck went back to dealership after being towed 70 miles. Where it was kept until Friday, February 6th. During this time at the dealership, they thought the problem was fixed, where again blew out all the oil while driving. Finally received the truck back. Check engine lights were still on but truck was holding oil and driving decent. Truck was doing fine until Monday February 16th. I was at a job and was driving home to finish the day. Again on the highway at highway speeds, truck goes into safe mode and limp it to gas station to again be empty on oil. It is still sitting there. Just last January the truck needed a new Transmission at 48,000 miles and at the same time a wirinig harness for the back-up camera needed replaced. Alot of things have been going wrong with this truck to be so new. It has cost me alot of out of pocket expenses.

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.
