2017 Chevrolet Colorado

The contact owns a 2017 Chevrolet Colorado. The contact stated that on numerous occasions while accelerating at low speeds, the vehicle shuddered and jerked. No warning light was illuminated. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000.

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.
