07-01-23 vehicle died out, wouldn't start, got jumped, still wouldn't start. No indicator lights or warnings. Towed vehicle to the dealership, where it was for 11 1/2 months with the determination it was the ecm and harness. Which it took that long to get. The vehicle was given back 06-14-24, even though it was in running condition, it was discovered parts were missing. Dealership put on order, received by end of July and installed. November 13, 2024, vehicle died out while driving on the freeway. Dashboard lit up everything, had to get the vehicle towed back to dealership. I have the onstar diagnostics indicating the same components as the original reason the vehicle was held for an approximate year. Dealership now has vehicle and we have to wait for them to do a diagnostic.

I purchased my 2019 chevy Colorado z71 new in Feb 2019 from a dealership. About two years ago I began having shifting issues from 1st to 2nd gear, it would shudder and seem almost stuck, this would only occur infrequently. Right after I hit 100,000 miles (about a year ago) I have had nothing but issues with the 8 speed transmission, my vehicle is unable to shift from 1st to 2nd without having the shudder occur, it feels like the whole truck is shaking and loses power at acceleration. I took it in for their recommended "service bulletin" which was something that I had to locate myself because gm has not once communicated about there being any kind of shudder issue and they performed a simple flush of the transmission, not the service bulletin recommendation of three flushes and a different fluid. My truck is now in the shop because I am unable to drive it due to this ongoing issue that gm fails to recognize and so far have spent $1,000 attempting to rectify this issue and being told that in order for them to actually perform the service bulletin, it will be another $225 to diagnose the problem, around $500-$700 to perform the service bulletin, and then if that "does not fix the problem", I will have to spend another $900 on a torque converter because that "could" be the issue, the dealership "doesn't know". Then the third fix would be to replace the transmission ($5500-$8500) this has been a known issue since manufacturing and gm is failing to provide adequate assistance to fix a known problem with their 8 speed transmissions. I no longer feel safe to operate my chevy Colorado in fear that it could cause serious injury to myself and others due to gm not being able to provide a safe fix to their ongoing issue.

Check engine light appeared when starting vehicle. Code read by local auto parts store. Thermostat failed at less than 50k miles, causing fan to run constantly and for an extended period time after turning engine off, despite outside temperature. Causes potential for overheating due to not reading temperature. Thermostats are rated to last 100k miles. Is not covered under Chevrolet's 5 years/100k miles powertrain warranty. Upon research, this has been an extremely common issue for Colorado trucks for many years and has not been addressed by Chevrolet. Many blogs are available online. This vehicle was a certified vehicle bought just over 1 years ago and would not be fixed by any warranty according to the dealership purchased from (bob fisher).

No warning lights are illuminated but have this consistent violent engine rattle/shuddering that is getting worse and worse. Also when looking under the hood the crank pulley wobbles/rattles when truck is idle. Was told it could be the harmonic balancer going out due to there being a gap between that and the crank. The truck only has 100,000 miles on it. I got it used at 88,000 miles and have barely had the truck for a year now, the steering wheel was intermittently difficult to maneuver and no warning lights illuminate, the truck shifts hard from 1st to second gear now and seriously hesitates to accelerate. This is extremely concerning and apparently an ongoing complaint for this vehicle and something should be done about it. Not only does it cause financial destress on the owners of the vehicles but also a safety hazard to the driver.

The component that’s failing on my truck is the apple car play and a check engine light (code p0024) which indicates exhaust camshaft position, bank 2. My safety and others safety is put at risk while having these issues: 1. ) the apple car play, having to take my focus off of driving to try and unplug my phone and plug it back in to hopefully fix the issue of using the navigation or phone calls while I’m driving during long road trips is extremely dangerous for myself, my loved ones and others on the road around me. 2. ) this error code is extremely unsettling to experience while 500 miles away from home and has caused an incredible amount of stress on multiple occasions. The light constantly turns on and off, leaving me completely clueless as to if I’m going to be left stranded on the side of the road. Both issues have been looked at by an automotive repair shop. And I’ve been advised to seek information to if there are any recalls regarding this issue. Check engine lights display for the exhaust camshaft position bank 2.

The vehicle was purchased new from courtesy Chevrolet in san diego, CA. After 500 miles on the odometer, I decided to change the oil with fresh castrol syntec 5w-30 which has the dexos 1 gen3 approval along with a new acdelco pf66 oil filter. Upon removing the oil drain plug and after all of the oil had been drained, I noticed the threads for the oil drain plug appear to be loose and perhaps broken free from the stamped aluminum oil pan. Luckily, I was fortunate to obtain a perfect seal while pulling on the drain plug and threading it into the pan. The attached images are from a new oil pan I purchased. The steel threaded insert inside the stamped aluminum oil pan has broken free and the only way to properly repair it is to have the factory oil pan replaced with another. The design is poor and there is no way to prevent the threaded insert from falling into the pan rendering the vehicle inoperable. I will be taking the vehicle into the dealership to express my concern.

The oil cooler lines are rusting and leaking. Seems to be a common issue going back 9 years since they started making these new Colorados from information I found online. Totally unacceptable for a truck to that is 4 years old to be rotting out. One of the lines is a nightmare to replace because of where it is inserted into the motor. Mechanic had to remove the front differential, axle, ac compressor, drive shaft, fuse box, and intake to replace a 60$ oil line.

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.

Date: April 19th, 2024 | location I-95 (pooler georgia) leaving costco 1 ½ 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.

The high pressure fuel pump detached from engine and snapped off flange and bolt in the head of engine . The part is available for inspection and was removed by dealership. Vehicle was being driven at highway speed at time of failure. Narrowly avoided an accident as truck lost power and went into limp mode. There was no prior warning leading up to failure.

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.

This truck has roughly 41000 miles on it. As I was driving home from work on [xxx], I heard a faint noise and then my truck just lost power and died on the freeway. There were no engine warning lights on and did not want to restart and stay running. After a few times of starting and dying the message on the dash said keep driving engine is in regen. This is a diesel truck and the newer ones have a regeneration that is done with def. I was unable to get it off onto the exit, but did get it off the roadway. The vehicle was towed into the shop on February 3rd, 2024. The shop had to order parts and said that it was just a faulty part. I received the truck back on March 14th. I drove it home from the shop and to work for two days putting roughly 100 miles on the truck. On my way home on [xxx] , the truck died again with no warning at all. Same symptoms, just no power and no warning. The truck was towed back to the shop where it still sits today. The problem is there is an issue with this thing dying without any warning at all. The dealer and Chevrolet techs have been unsuccessful in finding the problem. It has been almost 6 months in the shop with literally no idea of what is wrong. I feel this is a serious safety issue that could leave people or families stranded without any warning or idea of how to repair. I feel this should be investigated and brought to someone's attention. I have contacted Chevrolet, but unfortunately they have left everything up to the dealership. The dealer is auburn Chevrolet in auburn, wa. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine is needing replaced. I was driving down the interstate and the engine, electric control system, and stability lights all went off. The engine started shaking. The Chevrolet dealership says it's $6,500 before tax to diagnose or I can replace it for $10k before tax. I believe they know what the issue is, but not telling. The engine should not fail so. Soon.

Driving on interstate sudden acceleration then when truck turned off radiator fans would not shut off ,also problems with infotainment system since truck was bought never fixed they always told me couldn’t duplicate problem.

The brakes went out on the vehicle while my service technician was driving and he barely missed getting in an accident. We had it towed to the chevy dealer and the brake pump shattered causing damage to the exhaust clamp and they are telling me it’s not under warranty or recall but I see this is happened with millions of other chevy vehicles?.

My infotainment system as well as my driver display system black out and does not have a fix for it. I have had to drive my truck with no speedometer no safety info or system. I use my truck for work. I have no clue even how much gas is in my truck. Everything is controlled through this system.

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.

Just prior to 8/1/22, check engine light came on. They found p0014 set, lack of power, rough idle. They found oil pushed through bank 1 cam solenoid actuator and had to replace on 8/1/22. Check engine light came on again in mid August 2023. Found p0024 code and had had to replace the cam actuator again. This time gm has part on backorder, like they are fixing systemic issue with part. They could only replace by getting from another dealer. Still charged me for part even though it was just replaced 12months ago. Would like to know if this is a systemic issue with gm.

Exhaust leaks but it doesn’t do it all the time.

We purchased a 2019 Chevrolet Colorado December 2022. Beginning in January 2023 to current month July 2023 the vehicle has been at the dealership 4 times for the same occurrence: service stabilitrak and engine power is reduced a warning “ding” sounds (the same noise as seatbelt, door ajar, etc) simultaneously with the messages “service stabilitrak” and “engine power is reduced” the vehicle immediately is jerking or lurching, the engine no longer runs smoothly and is misfiring. The engine power reduced does not allow safe acceleration, and the vehicle is unstable (as it moves it feels like driving over a thousand speed bumps over and over), the engine misfiring is heard from the exhaust and the vehicle is visibly vibrating, on acceleration the maximum speed is 20 mph. All 4 times this has happened while driving the vehicle on highways in traffic. We are left unable to get out of the way of moving traffic, unable to accelerate, change lanes or make turns safely. Three of the four times we had the vehicle towed to the dealership. The last time the vehicle did this fortunately I was near our local dealership and drove it less than a mile so the service people could “witness” what I had been trying to explain what’s been happening with this vehicle. This is a very serious issue! my husband is 75 and very ill. I have to drive him 100+ miles for treatments on a regular basis. We cannot continue to be put in danger because of this vehicle default. We need this problem fixed not only for ourselves but for the safety of others, including unsuspecting drivers and innocent passengers, young, elderly, disabled, some simply misunderstanding our vehicles “failures to perform” in traffic on the roads. A trusted vehicle is very important. A stabile vehicle with sufficient engine power is a must if we are going to put it on the roads. “service stabilitrak” and “engine power is reduced” is not new. General motors needs to take action to correct this problem and educate dealers.

From a stop, accelerating has occasionally caused transmission to shudder, limiting power and ability to follow traffic until transmission reengages and power is restored. This creates an unnatural traffic pattern and puts myself at risk. After much research it appears the problem is with the transmission and torque converter. The engine may produce more torque than the transmission can handle. Problem started out infrequently, but has increased in frequency over time. Please reference report #11449007.

06/13/2023: odometer: 86881 transmission-2nd shift: flare, 3rd shift: rough shift flare, 4th shift: shutter. Excessive metal particles in the fluid. No transmission codes or engine light detected. Result was a new rebuilt transmission. 11/01/odometer: 90239 engine code: p00b7 coolant flow restriction, stuck thermostat. Result was to replace thermostat and flush coolant system. 12/06/odometer: 91701 no codes detected. Fluids noticed on pavement occasionally. Valve cover gasket, vacuum pump gasket were failing. Result was to replace all parts. 02/25/odometer: 92885 code-engine overheating, idle engine. Critical 260 upon cold start. Failing temperature sensor. Result was to replace front and rear temperature sensor. Driver seat has begun to unravel and separate at the stich line on the side closest to the door. No repairs have been made. Issue began years ago. Approximately 2018. The area was small and has slowly widened. Approximately 6 inches currently even with avoidance of stretching and being cautious of that area. I do have documentation of this events and repairs if they are needed.

Unknown other than I requested vernon Chevrolet in CT repair my recall on January 2, 2023 but have yet to hear back.
