40+ mph the transmission sounds a rumble strip as driving over
Transmission shudders when going do the road. happens at both lower speeds and at higher speeds in town and on the interstate. hard shifting as well when vehicle is not up to operating temperature.
It feels like i am running over rumble strips when going 40-60 mph and low rpm. a brief internet search reveals that this is a common issue that appears to be related to the transmission. the issue began recently. i have 40k commuter miles on the truck.
Twice now my 2017 w/~41000 miles has gone into instant, no warning or grace period, but an instant drop to a forced 10 mph in the middle of traffic, this last time on a highway with no shoulders during rush hour. the three codes thrown the first time (i don't have the codes from the second time but the dealer is ordering a new ecm based on the u0401 code): rc (radio controls): b1325 - control module power circuit - low voltage ebcm (electronic brake control module): u0401 - invalid data received from engine control module - invalid data ecm (engine control module) p200c diesel particulate filter (dpf) high temperature along with the codes the check engine, stablitrak, and traction control lights came on - however braking was not affected! regardless, this programmed 'limp' mode is insanely reckless with total disregard for the safety and welfare of the vehicle occupants, there is absolutely no safe place or reason to deliberately cripple a vehicle while in traffic! some european manufactures at least give you a warning with several engine restarts to let you drive normally to safety and then a dealer for service ' but apparently emissions laws in the us take precedence over human life. limp mode can be disabled for emergency vehicles but the dealership told me it was illegal for them to do it for me. the dealership has been great but limited to what they can do because of gm requirements. they are currently looking into the problem and has ordered a new ecm as a second phase in troubleshooting the issue (first was reprogramming the ecm) however there is still no excuse for forcing a vehicle into limp-mode while in use - i have lost all faith in this vehicle and gm and cannot trust it for my own yet families safe use.
Transmission is stuttering randomly every minute or so, it vibrates the car and feels like i'm running over rumble strips.
Transmission shutters when going at a constant speed. this started around 10k miles and the dealership has tried to fix it three times without success. first two times they replaced the torque converter and third time they replaced the transmissions fluid. the truck also shifts very hard from first gear to second gear with a huge jerking motion around 10 mph. this is very dangerous when driving in parking lots or anywhere near pedestrians. finally, when compressing the brake at 25mph the truck jerks very violently down to the next gear. the transmission in these trucks needs to be recalled and replaced soon.
Transmission shudder. seems common after 40,000 miles on the majority of 2017-19 colorados. truck would vibrate like driving over a rumble strip around 55+ mph after transmission fluid would warm up above 80 degrees f. should be a recall because i had to go through hoops to get them to even look at the transmission because they thought it was a tire or wheel weight. super inconvenient and time consuming.
I got a check engine light while and engine goes into reduced power mode. you can't drive in reduced power mode! i have to clear it to move the truck. i did a scan which showed a p2138 code. but its just in memory and the dealer wont fix it unless its an active code but can't drive to the dealer in reduced power mode. its a catch 22
Transmission shuttering and jerking. recall needs to be done immediately.
Vehicle shudders/shakes when accelerating or maintaining speed. can be light shudder, like driving over a bumpy road. or can be enough to make everything sitting in dash to shake violently.
Hard shifting & slipping of the transmission started at about 10,000 miles. dealer unable to repair even though they tried 4 times including a remanufactured transmission. not sure what type of damage is occurring to the transmission with this hard shifting.
Shudder and slipping in the gears caused by bad fluid and torque converter.
While accelerating on the freeway from approximately 65mph, the stability control system engaged and took control of the acceleration of the vehicle. roads were dry without ice, snow or rain. the stability control reduced power until the engine died even while pressing the accelerator to the floor. the engine would not restart for approximately 5 minutes. this occurred 3 times on different interstates on a trip. we were forced to carefully move to the right shoulder while our vehicle was slowing until the engine died. my wife and i were lucky we were not involved in a serious accident. onstar notifications sent the following in an email, "an issue with the engine and transmission system in your 2017 chevrolet colorado has been detected. please service your vehicle within 7 days."
At speeds 45 mph transmission makes a load thumbing sound and start switching back and forth for gear. at speeds 60 up to 70 mph a shuddering starts mostly up grades and down grades. from review there is a bulletin gm 16-na-175. from what i read this doesn't fix the problem. there are numerous of complaints.
Tl* the contact owns a 2017 chevrolet colorado. while driving highway speeds, the contact noticed that the tachometer fluctuated and the transmission shuddered. the vehicle was taken to an unknown dealer where it was diagnosed that the transmission torque converter failed. the dealer replaced the torque converter and the transmission was flushed. the dealer also reprogrammed the transmission computer. the manufacturer was contacted and provided case number: 9-4982753540. the manufacturer issued technical service bulletin number: 4942742 pie0405c (engineering information torque converter shudder). the approximate failure mileage was 13,500. *tt consumer stated torque converter had wrong transmission fluid from factory.*jb
Experience transmission shudder while driving vehicle. could cause issue while passing other vehicles due to loss of power. the amount of money these newer vehicles are charging, transmission shifting should be flawless. not sure if this is going to get worse and cause an accident. could it jump gears while trying to come to a stop? this is ongoing and needs to be addressed and a remedy by the manufacturer soon.
Whole vehicle shutters when accelerating anywhere between 35 and 75 mph. this happens while driving straight on a city street or highway. it is equivalent to running over rumble bars every other second on a completely smooth road. the tachometer can also be seen jumping 100-200 rpms during the shutters.
Tl* the contact owns a 2017 chevrolet colorado. while driving at high speeds, the vehicle started to violently vibrate. the failure also occurred when accelerating from a stop. the vehicle was taken to dyer chevrolet fort pierce (4200 us highway 1, fort pierce, fl 34982, (772) 242-3116) multiple times for the failure where the transmission was serviced and flushed; however, the failure recurred. the vehicle was not repaired. the manufacturer was made aware of the failure and the contact received a case number. the failure mileage was 17,000.
Transmission shudder. fells like driving over rumble strips. gm knows of this issue but keeps putting these 8 speed transmissions on the road.
Sept 2018 have noticed that truck seems to vibrate, shudder at 50-60mph. vibration, shuddering got worse, even at 25mpt. october, i contact service advisor who believes might be torque converter need appt to verify november finally got appt with service dept . they verify it is torque convertor and order parts. december parts in & truck in for 3 days as parts installed. told this should solve issue, but chevrolet working of another fix for 1st quarter of 2019. to date, i have not noticed any issues of vibration.date.
The vehicle has a shudder in the transmission under light throttle acceleration between about 50 and 80 mph on the highway. it feels as if i'm driving over rumble strips on the road for about a second. then it will stop for a second or two, and then shake again for a second. without throttle, no shaking occurs. this has been occurring for about two weeks, or perhaps the last 500 miles. it might be described by bulletin 18-na-177.
Truck bogs down, looses power when taking off from a stop. front tires feel like they are skipping even though truck is in 2 wheel drive especially up hill. once truck gets going it rumbles and vibrates so much it bothers your ears, constantly loosing power and speed as your driving. was told it was the torque converter and it was replaced. truck continued to have same issue. truck then 'blew up' (dealership words) while i was driving 75 mph down the highway. dealership stated 'it was like your truck went into low gear while you were driving and it should never be able to do that'. had fluid flush and replaced again and rumbling and power lose still occurring.
Experiencing electrical problems causing starting issues, while driving failures in dash indicator lighs, speedometer , tachometer, shift control indicator lights, and transmission control. loss of power to the point truck almost comes to a stop and then surges, twice it has accelerated traveling up to 50ft estimated.
When automatic transmission downshifts into 1st gear coming to a stop, it does so harshly and lunges forward. when nosing into a parking space with a concrete wall at the front of the parking space, if i had not allowed enough space for the lunge, the vehicle would have impacted the wall . this condition, along with other transmission shift irregularities, happens periodically and i must remain aware, especially coming to a stop near a cross walk.
8 speed transmission has hard shift when at low speeds and when going into reverse
When driving at low speeds my 8 speed auto transmission - clunks or thuds - specially from 1st - 2nd - its sounds like a bang - took it to dealer - said chevy knows about it - but there is no fix yet.....great!
At 21000 miles felt like driving over rumble strips and tach would move in cruise. dealer flushed trans. 4 months later at 29000 miles same problem but now shifting hard noticed during acceleration and deceleration. changed out converter and flush. now 3 months later and only 2500 miles later it has started all over again. so back to the dealer i will go. am starting to regret buying a chevy instead of staying with my trusty ford
I have had repeated issues with the transmission and the transmission will not shift out of 5th gear when in tow mode and when towing load under specifications. i have started the lemon law process but the manufacturer has denied my claim as of today.
8-speed automatic transmission in indecisive when it comes to shifting between lower gears while driving. transmission making clunking "thud" sound when shifting out of park and into reverse. gear hunting experienced at lower speeds and gears while vehicle attempts shifting.
8 speed automatic transmission - rough shifting, usually when driving between 40 and 60 miles per hour. truck intermittently feels like it is riding over rumble strips. transmission seems to be hunting. possible issue with torque converter.
In cold temperatures that the northern states experience (around 4 degrees f) the truck will intermittently die in the middle of the road while driving. complete power loss with no warning, which seems to happen at any time. when the weather is above 10f consistently it seems there are no issues. extremely dangerous and can leave you suddenly without power while driving.
The problem with my chevrolet colorado 2017 truck started with when the new truck barley had under 200 miles on its odometer. the issue is the truck starts to vibrated at a speed of 50-55 mph like if you are going thru speed bumps and the noise stops when you go over 60 miles per hour. i have done a simple 20 minute reserch and have found out that there are other individuals that have had the same issue with their same year colorado truck's. i took my truck to the dealership where i bought the truck. they knew exactly what the issue was. they are in the process of replacing the torque converter. looks like a major concern to me.
At 1400 miles truck started a heavy pulsating vibration between 50 and 55 miles per hour. took it to myrtle beach chevrolet where they balanced the tires. it did not fix the truck. still vibrating now starting at 20 miles per hour. severe pulsating vibration at 55 miles per hour. going back to the shop next week
After about 600-700 miles on new vehicle, after truck sits overnight when first started you could feel what seems to be the the torque converter was engaging as it the transmission had lost pressure. then while driving anywhere between 40-65mph converter seem to be unlocking and locking which cause a very bad shutter as if you were driving over bricks, and then when coming to a stop the transmission down shifted into 1st gear very very hard, which is hard on the drive line. took back to dealer they keep it 3 days and flushed trans fluid with a new special fluid. the shuttering has stopped but the other 2 problems remain, so i'm thinking now they'll have to change the converter out.
When automatic transmission downshifts into 1st gear coming to a stop, it lunges forward. if when nosing into a parking space with any kind of pole or vehicle directly in front of my truck, not leaving enough space my truck would hit whatever. when driving slowly with my 8 speed automatic transmission sometimes it rattles as if i am on a rumble strip and sometimes it just clunks or thuds. this and other shift issues make me even more hyper vigilant when driving. 6 months after i purchased my brand new 2017 colorado, during a spell of negative degree weather i lost the following: my cruise control, traction control, four-wheel drive; my engine light came, oil light all lights came on and my radio stopped working. i was told by my chevy dealer that this was normal in cold weather. next, i was informed it must be because i washed my vehicle the day before. this went on for a few months, with me showing them videos and them telling me they could not duplicate the issue. october of 2018 they replaced my radio because evidently the radio had a bulletin that showed all of the things i had complained about. i want to say this happened in excess of 10 or more times. driving to my mothers one evening in the dark my dash lights were not dimming correctly and then went out. as i got to a four way intersection with cars coming they came on so brightly i almost got in an accident which prompted me to make an appointment and i wasn't willing to hear silly excuses.
My truck was parked inside my garage the whole night. the following morning i noticed 2 areas on my garage floor underneath the vehicle fresh liquid. i touched to check what they are and i confirmed by the appearance and smell that they are oil. i crawled underneath my truck to check which part they are coming from. i saw one area on the front right axle oil leaking.i also took pictures of the leaking oil.i bought my truck on august 24,2017 and i discovered the leak on sept 14,2017(.less than a month old) the dealer said they replaced the axle seal and it should fix it.
Tl* the contact owns a 2017 chevrolet colorado. while driving at an unknown speed, the vehicle accelerated and jerked. additionally, the brakes were applied, but failed to respond and the brake pedal traveled to the floorboard. in addition, the contact heard an abnormal scratching noise. there were no warning indicators illuminated. the vehicle was taken several times to gilroy chevrolet (6720 automall ct, gilroy, ca 95020, 408-842-9301), but they were unable to duplicate the brake failure. the dealer diagnosed the acceleration failure as the four wheel drive being engaged. the vehicle was not repaired. the manufacturer was notified and provided case number: 8-4000-730943. no further assistance was provided. the failure mileage was approximately 17,759.
My complaint along with thousands of other chevy colorado and gmc canyon owners is the lack of a 4wd indicator reminder light in the gauge cluster. it seems that gm decided that just a tiny led light which is basically impossible to even see in daytime was enough. the only thing that comes up on the dash is a message that reads "shift in progress" but no other indicator to let you know that the transfer case has in fact made the shift or what drive mode it shifted into.the other problem is the location of this 4wd shift knob. it's located to the left, below and behind the steering wheel next to the headlight control knob as my attached photos will show. it is impossible to see while driving since it's view is blocked by the steering wheel and in order to actually see what drive mode the vehicle is in you must take your eyes off the road while driving, try to either look through the bottom of the steering wheel, around it or below it to see the position of this knob. i myself was driving on the beach in 4wd when i went fishing. when i left the beach my truck wasn't driving normally and i realized i never shifted back into 2wd. i literally had to take my eyes off the road to look at this knob to check to see what position it was in and i came very close to having an accident. also driving on pavement in 4wd can cause serious damage to the driveline and also effecting the stability control system and abs. this is the first 4 wheel drive vehicle i've owned that lacked a 4wd indicator reminder light. gm actually has an off-road 4wd information screen in the dic on some models but for some reason they didn't make this screen available on the colorado. this feature should be standard on any of their 4wd vehicles or at the very least a 4wd reminder indicator light on the dash due to the unsafe location of the 4wd control knob. this is just an accident waiting to happen!
I am writing this after another chevy colorado owner posted about this. i have the same issue. their complaint is #11023887. there is no indicator on the dash that shows when the vehicle is in 4 wheel drive. the only indicator is a small led light on the knob that is partially hidden by the steering wheel. this is a hazard, because this is a prime location for a knee to hit the knob, turning the four wheel drive system on by accident. so you can accidentally turn on 4 wheel drive, and not know until you are driving down the road. this is not ideal. because you have to take your eyes off the road to find the knob to turn it back to 2 wheel drive. this could cause an accident. there really needs to be a 4 wheel drive indicator on the dash, or gm needs to come up with a fix. driving in 4 wheel drive on dry pavement can also cause severe drive train damage.
Air conditioning is intermittent/blows warm/emits fog from vents. the dealer says no fix available yet cites per doc id:5125499.says engineering is studying problem. mine stops working-blows warm with in 1/2 hour. also in stop/go traffic the transmission downshifts abruptly and causes truck to accelerate forward-have to apply brakes hard to avoid collision. dealer says can not repeat but shifting is consistently abrupt and i have asked about software updates to allieviate this safty concern to no avail
Fuel pump weld crack, service 4wd message displayed, clunking in rear end all dismissed repeatedly from dealership i purchased my vehicle from. i bought this truck new off the lot which has been in the shop in excess of 10 times for multiple issues. the 4x4 started november 2017 i was told it was because we were having abnormally cold weather and it would come out of it. it has been in multiple times since then and they were unable to duplicate. clunking in rear was dismissed as nothing, could not duplicate. i started smelling burning plastic, then when starting my vehicle in the morning the exhaust smell was so overpowering that it would gag us. the burning plastic smell was intermittent while driving and that was only after driving the truck between 2 to 20 or the full drive home and sometimes not at all. i had been nodding off, getting massive headaches and sick to my stomach while driving my truck, so was my daughter. no matter what they had my truck for, they could not duplicate the issue and i had a loaner for a week at a time. i took my vehicle to another dealership who just ended up sealing my pickup box, replacing fuel pump module, installed a body plug per a bulletin, per bulletin applied lubricant to both rear leaf springs and torqued leaf springs to specs. transfer case control module had a bulletin for which my dealer stated they put dielectric lubricant. i was driving a vehicle with my child in it with carbon monoxide poisoning us based on the symptoms we were both suffering, exactly when would that have been duplicated, at autopsy???? i don't trust this truck, i don't want to drive this truck, i hate this truck now and i am stuck with 5 years of payments and something that tried to kill me. how is that for safety!!!! my opinion only!!!
I have a 2017 colorado z71. i bought it specifically so that both my wife and i could use it as necessary, (being of quite small stature she is unable to drive a full size pick up) however, due to the following ongoing issues she has yet to agree to drive it out of concern for her safety. it presented with what have become chronic transmission problems immediately after purchase. i have returned it to the dealer multiple times to no avail. initially it intermittently shuddered to the point of vibrating the entire vehicle as if driving over rumble strips while driving on either streets or highway. then it began lunging forward unexpectedly and uncontrollably when presumably shifting to the point which feels like having been rear ended by another vehicle while driving on both streets and in parking lots. during the span of multiple visits the dealer has replaced the torque converter, as well as replacing the transmission fluid. despite no longer shuddering, the vehicle still lunges randomly. i was informed by the service manager during my latest visit about the lunging that they knew what the vehicle is doing, and that there is no fix for it...which is absolutely unacceptable. i'm quite concerned about my vehicle lunging unexpectedly and uncontrollably into a pedestrian or another vehicle.
