My son was driving the vehicle when it lost power and he had to maneauver to the side of the road putting himself and others in danger. The truck was not able to drive forward, but could only drive in reverse. There were no warning lights or other indications that the vehicle had a problem. I had it towed to a mechanic who said Chevy Colorados have problems with their transmissions and it would need to be replaced.

Purchased vehicle new in 2017 with 14 miles. In June 2018 at 17,500 miles vehicle developed a sever transmission shudder. Took the vehicle to the Chevrolet dealership where purchased. They replaced the transmission fluid and torque converter. Now, in July 2023 at 79,000 the transmission shudder has returned. This shudder affects my ability to control the car’s speed, acceleration, and deceleration and increases the risk of collision. Took the vehicle back to a dealership. They now recommend a full transmission replacement at $5,900. They will cover only $237 of the cost since the vehicle is past 5 years and 60,000 miles.

8 Speed transmission slipped as I was going around a corner causing my 2017 Colorado stop suddenly causing the cars behind my to swerve to avoid me. Then the excellerator linkage or something caused the engine to rev out of control when the transmission finally stopped slipping causing me to run the truck off the road. This slip and then uncontrolable exeleration has occured 3 times since I bought it, This truck is a LEMON!

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

The contact owns a 2017 Chevrolet Colorado. The contact stated that while driving at 55 MPH, the vehicle inadvertently downshifted before returning to normal functionality. Since the failure was first experienced, the failure became a regular failure. The check engine warning light was illuminated during the failure. The vehicle was taken to the dealer, who determined that a transmission fluid flush was required. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 55,000

There is an active service bulletin for 2017 Chevy Colorados. My vin does not fall under that service bulletin. I started two case numbers with Chevy. My truck is in the shop for ref service bulletin # 18-NA-355. Same problem and the same fix. Mine got so bad the control arms need replaced. Please add my vin to the service bulletin so Chevy will take responsibility for their manufacturing mess up. Thank you.

My vehicle shutters on highway. I was told by a few Chevy representatives that they would help fix it even though it’s out of warranty. This is a known problem across the USA and they should fix it at no charge to customer.

The oil coolant line has just failed for a second time in two years on our 2017 Chevy Colorado that only has 50,000 on it. In both cases I was driving down the road and the line ruptured and alarms started going off to shut the engine off. This is very dangerous to have to immediately stop in the middle of the road and then left stranded (especially in the middle of a cold MN winter). The first time this happened the vehicle was under warranty and our dealer towed and fixed the vehicle. The second time, it is just 8 months past the warranty time (still under the warranty mileage limit). This is now a $1200 repair for something that should not be happening any way. This is a known, common issue with GM and they are doing nothing to solve this problem - or even warn their customers of this safety issue. Two catastrophic failures of an essential drive train component in a vehicle with 50,000 miles? Also in both cases there was no warning of any kind before it happened. No warning lights or symptoms. It just all of a sudden blew both times and left me stranded on the road.

My car was shuddering (almost like the wheels didn't have enough power) and it felt like I was going over a rumble strip. After some research I found out that Chevrolet knew of this problem and acknowledged it in a service bulletin in 2018. The problem was that the transmission oil Chevrolet had used was failing and needed to be replaced. The oil Chevy had in there was causing the Torque Converter Clutch (TCC) to Shudder or slip. Chevrolet never notified its customers because they said this would not harm the truck. However they're wrong, if the transmission does not have the right oil and is causing the TCC to slip, this inevitably would ruin the clutch and thus is a manufacturing default and should be replaced at no cost by Chevy. The newest service bulletin on this problem is N0: 18-NA-355 (https://static.nhtsa.gov/odi/tsbs/2019/MC-10163890-9999.pdf) Chevrolet said this was not covered by a warranty and wanted me to pay $500 to fix their mistake of putting in faulty oil in my truck. They then offered me to pay $80 . They also refuse to extend my warranty and cover the remaining $80. This is a safety problem because it could cause the transmission to seize up if not fixed. Because this has been well documented in many other customer cars, I believe they should be forced to Recall and notify all customers and pay for this procedure. My car was inspected and flushed by car dealer (Chuck Olsen Chevrolet in Shoreline WA). There were no warning lamps, or messages. It failed why I was driving on a two hour road trip. The rumbling was so noticeable I initially thought my wheel was falling off so pulled over to make sure my tire still had all of it's bolts. Turns out the fluid Chevy used in my transmission was to blame. In the owners manual it says you should flush your transmission at 72,000 miles. My truck only has 58,000 miles.

In March of 2021 purchased a used Chevy Colorado from Jake Sweeney Automotive Group in Cincinnati Ohio. The vehicle seemed very sound, but over time a rumbling sound was starting to take over the cab of the truck. I felt it was coming from the rear end of the truck. I took the vehicle into an independent mechanic. They removed the tires to make sure it was not the brakes. They ended up telling me where I thought the sound could be coming from was the differential. They could not tell me exactly what was wrong without tearing the differential apart. I took the vehicle back to Jake Sweeney Service in Lebanon Ohio because this Service Center was closer for service. After their service inspected the vehicle they determined it was an issue with the differential. Again, they could not tell me exactly what was wrong until they tore into it. The independant mechanic gave me a text on GM-Techlink.com that indicates GM is having issues with this type of differential. After some arguement with Service Tech and Manager of Service Department. They agreed to cover 25 per cent of the of the work done to make differential right. I was not in agreement with this due to it is a GM problem. I made contact with GM to complain to them of their issues with the differentials on these vehicles. After a couple months of talking to the claims writer. A supervisor called me to inform me they would cover 25 per cent of the cost to repair the vehicle. Again, I was not in agreement with GM only covering 25 per cent of the cost when GM has an issue with these differentials. It looks from reading the GM-Techlink.com GM is aware of 2017-2019 differentials in the Colorado and GMC Canyon models causing the whining, growling and grinding sound. The link indicates there is a machining issue on the surface of the carrier bearing bore. I understand, I have put miles on this vehicle before I was aware of this issue. But my feeling is GM has put an unsafe and faulty vehicle on the road.

Vehicle vibrates and/or shudders during light throttle acceleration at a steady state, promoting a driver to accelerate quickly to overcome the disconcerting shudder. This definitely should be a safety recall as GM has acknowledged the problem in a Technical Service Bulletin #19-NA-018, prevalent in many models & brands including Cadillac, Chevrolet & GMC (even Corvettes 2015-2019 models). Suggested repair is for dealer to fill & flush transmission pan 3 times(!) with 7 liters of Synthetic LV ATF HP fluid. Other complaints on this site question the effectiveness of this repair citing recurrence of shudder. Very disturbing & unsafe condition.

I have had this complaint before and previously lodged a complaint about the transmission. First time at the dealership, they said they couldn't feel any of the shuttering I was talking about. Second time they ended up doing a transmission flush. It felt exactly the same and seemed to get worse. Third time they said there was nothing they could do. Suggested I run the truck in tow mode. That was better for a short time. Dont know what to do now. Second complaint is the back up camera. Can bearly see out of it no matter how clean I get the camera. Asked dealership if the was any recalls on it they said no but told me they had so many complaints about it. Would seem to be a factory defect but what do I know

Hard shifting, missed shifts, shudder from TQ converter. For six months the vehicle has been shifting had at random times during shift sequences. Hard shifts occur on both moderate acceleration and hard acceleration. Shifts can only be described as sudden and violent, feeling something like a U-joint failure, broken transmission mount, or a clutch slipping and then slamming into gear. The hard shifts occur and any speed and any gear, but are very noticeable around 3rd / 4th. The TQ converter slips on acceleration only. Has been in the dealer 3 times for a total of 7 days so far with one technician claiming it needs a new TQ converter and possibly a new transmission. Other techs claim they can't find the problem. No codes, no lights. Dealer claims they can feel the problem but have failed to diagnose it. Failure of this could pose to be a serious safety issue if it happens at highway speed in traffic. GM has the inventory of 6L50 transmissions on lockdown.
