What owners report
Date: [redacted] | Location [redacted] Leaving Costco 1 after entering entrance headed to Savannah. I was traveling at approximately 60 miles a hour with heavy traffic alongside me and a tractor trailer behind me when I felt my Truck quickly de-accelerate on its on. Then I saw the "Sudden Warning on Dashboard, "Reduced Acceleration - Drive with Care" then the 2nd Warning on Dashboard, " Service Traction Control." I was almost REAR ENDED by the Tractor Trailer. I was never so startled but I keep my nerve....got over to the right lane at slowed speed (It was weird. Speed slowed but felt like I was in high gear....) I droves about a mile .... got off at next exit and pulled over at gas station. I turned car completely off and tried to reset computers, but it would not. I decided to drive under 35 miles a hour on side streets to Dan Vaden dealership.
2024 Chevrolet Colorado with intermittent safety defect at highway speeds. Vehicle displays P215B along with Service ESC, Service Traction Control, and Reduced Acceleration. Speedometer becomes erratic and the vehicle loses reliable speed signal at highway speed. Dealer kept vehicle for 15 days, stated repairs were made, but the same issue returned within about 2 miles of pickup on the highway. Vehicle was returned to dealer immediately. As of April 2, total days out of service will be 21. I do not believe the vehicle is safe to drive or safe to transport my family in. GM case has been opened. This is an ongoing safety issue involving loss of speed signal and reduced acceleration during highway operation.
My 2023 Chevrolet Colorado (2.7L, approx. 49,000 miles) experiences sudden, intermittent loss of motive power involving the 8-speed automatic transmission. The transmission sets codes and the vehicle drops into limp mode, capped at roughly 45 mph, without warning. The most dangerous symptom is a total loss of acceleration from a stop, especially on inclines - pressing the accelerator produces no response. On one occasion, stopped on a slight incline, the vehicle rolled backward toward the car behind me when it failed to move forward on accelerator input. I narrowly avoided a collision. On a separate occasion, after pressing the accelerator with no response, the vehicle then suddenly lurched forward into cross traffic; repeated presses produced inconsistent, delayed engagement, nearly causing a collision. …
What component or system failed or malfunctioned, and is it available for inspection upon request? To my knowledge, which is limited on vehicle diagnosis, the engine valve body is having an issue finding a gear when starting from a stop. How was your safety or the safety of others put at risk? The vehicle engine will sputter and jolt forward and attempt to go to a higher or lower gear when approaching the stop . Has the problem been reproduced or confirmed by a dealer or independent service center?The problem is reproducible, but the dealership is stating i would need a check engine light to have it serviced or seen. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? …
The Stibilitrack in the truck went out just after 20 minutes of driving in 34 degree rainy weather at 65 mph. Found out that it was the passenger front bearing reluctor had chipped away, which is what the wheel speed sensor reads. Once one those go out, you lose Stibilitrack and ABS. I believe that this is a significant safety issue, and a poorly engineered/designed system. The rear system reads gear which is what should be in the front should have as well, not a "magnetic ring". This should be fixed so that noone gets injured or killed. It's also a waste of consumer money that you have to change out an entire wheel bearing hub assembly to fix the issue. Shame on the company. In the photos, notice that half the black ring (the reluctor) is missing.
The wiring harness was touching the air condenser line. The line gets hot when air conditioning is used. It melted causing my truck to throw a lot of random alarms. It also would turn my cruise off and make it down shift all of a sudden startling me. Melted wires are also a fire hazard. There is a bulletin for wire harness chafing that GMC knows about this issue. If it had melted something major and shut my truck down while driving down the interstate it would put me and anybody around me in danger. It was wired back together but is still not fixed. Might need a new wiring harness.
Received a P2138 Throttle/Pedal position sensor/switch "D"/"E" voltage correlation code while driving that caused "Reduced Power" and "stabilitrak" errors. The reduced power mode it went into made the truck unable to accelerate in a safe manner and made the truck "jump" wildly as it attempted to accelerate.
The computer screen jumps around with the dash data when you are driving. The radio changes functions and channels. This is a huge distraction and dangerous when driving. Additionally, when you turn the radio off the screen keeps jumping around to different functions and channels.
