The problem started two months ago, with a loss of engine power and a stability track warning on the dashboard. This happened occasionally while driving, often going away on its own by turning off the vehicle. Two weeks ago, I took it to Chevrolet for an inspection. They did a general inspection and said it was a factory defect. Now, the vehicle has the problem constantly, and there are times when it's undriveable. That's a risk for me.
The contact owns a 2018 Chevrolet Colorado. The contact stated that while his daughter was driving at an undisclosed speed, the vehicle lost power and the driver observed a high pitch sound coming from the engine compartment. The check engine warning light was illuminated. The vehicle was steered to the side of the road and turned off. The vehicle was not able to restart. The vehicle was towed to a dealer where it was diagnosed and determined that the high-pressure fuel pump had fractured and there was a fractured bolt inside the cylinder head that needed to be replaced. Additionally, diagnostic trouble codes: p0089, p228c, and p2c1f were retrieved using a dtc machine. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 90,369.
P2738 pressure control solenoid valve 6 control circuit low voltage. Whenever you drive, the transmission will go into limp mode every now and then. It will say low oil pressure and throw another code of p0700 mil request from tcm. This is a common issue that I have researched and would like to know a way forward. I've only had the vehicle for 6 months. Within city limits as long as you don't push the accelerator too much (50mph within 2 minutes) it runs ok until the vehicle comes to a stop. Also, when you get on and off of the freeway, same issues make it go into limp mode in which you will have to shut the truck off and start up after a few minutes to reset.
The vehicle stuttered upon acceleration between 20mph and 35mph. After the 2018 chevy Colorado was taken into the chevy dealership for inspection, the torque converter failed at roughly 76,000 miles. A bad torque converter can potentially cause an accident. It can lead to engine revving issues, sudden speed changes, which can be dangerous while driving. The torque converter failed and left metal shavings in the transmission causing the transmission to need replaced as well. This was diagnosed by the chevy dealership and has a repair ticket of over thirteen thousand dollars. ( $13,000. 00 ) which most people can't afford to absorb. After a quick google search, this appears to be a common problem. There should be a recall to fix this issue.
“service trailer brake system” won’t turn over but will crank transmission shifting very hard around 3rd and 4th gear.
Master cylinder leaked into booster an brake fluid got into vac pump. Broke the pump an damaged the end of the cam. Was told metal pieces of cam that broke off where in motor. Had to take a 3600 dollar loss for selling less than what was owed. Car vibration on bad cam. But brakes were repaired with a new pump.
The issue is with the transmission not shifting as should. The issue is called shuddering and seems to be a know isuue. If you google search issues with 2018 chevy Colorado this is the first issue that comes up. This could cause an accident. If gears aren’t shifting properly and I cannot excel as needed I could be rear ended or cause me not to be able merge into traffic if once accelerating it shudders and causes my speed to slow. I think there should be a recall for this issue.
A/c lines near driver side wheel well has chafed through fuel line and wire harness. Causing a couple thousand dollars in damage. Nor warning indicators leading up to either incidents. My chevy dealership mis diagnosed it twice and has now found the issue. Fuel lines leak can cause fires and as far as the electrical issue I've been left stranded with my 3 year old daughter a couple of times. . Have looked up forums and many people have had the same issue.
Key cannot be removed from ignition. I bought my truck 6 months ago and it’s been in the shop 3 times bc I can’t remove my key. Last time it left me stranded at my veterinary clinic at 1 am after dealing with an emergency because the battery died. It appears as though I am not the only one having this issue.
About a year ago, I started getting a slight shudder in my transmission so I took it to the dealer for repair. They couldn't get it to shudder. Several times I'll be driving down the road at or around 45mph and the truck will start shuddering so bad I feel like I have to pull off the road. Every time I take it to the dealer for repair I end up losing my truck for a day and they tell me they can find anything wrong even though this is a known issue and there is a TSB out to fix the issue.
My Colorado has completely shut down/powered off when making a right hand turn. Twice now. I'll be coming to a complete stop, accelerating through the turn and then all of the sudden, without warning, the truck loses all power. No flashing dash, nothing. I have to coast to the shoulder of the road, turn on the hazards, put in park, and restart the vehicle. This has happened twice now. From some online forums I've read, the problem only seems to get worse and has happened to others around 30-40 mph. My car is still under manufacturing warranty for another 500 or so miles. I took my truck into a certified chevy repair shop and after a week of troubleshooting and trying to recreate the problem, they have found "nothing" wrong with the car. If this doesn't get fixed and continues to occur, it's only a matter of time before an accident happens.
Vibration and shuttering at 40-80 mph coming from engine.
