Needed to replace brake booster vacuum pump at 50,000 miles. cost me $468.18
The transmission (6spd automatic w/v6 engine) of this vehicle is known to have issues that will surprise you if you aren't already aware of them. the issue affecting safety the most, is the occasional engine acceleration while applying the brakes as the transmission downshifts to a lower gear. it causes the car to actually accelerate momentarily as you apply the brake even harder to arrest the increased speed. i was driving up a slight incline at about 35-40 mph when all of a sudden the car in front of me came to a complete stop because the car in front of her had stopped completely. i had driven this road for more than 30 years and had never seen anyone come to a complete stop as the first car did in this area. five(5) of us were all surprised. i was the third car. as i firmly applied my brakes, the car initially slowed down but then it felt as if it was trying to accelerate and unfortunately i was unable to stop in time, although i only lightly tapped the car in front of me, followed by 3 more cars in back of me. at first i was surprised that i wasn't able to stop in time and then it occurred to me that the strange feeling i felt as the vehicle slowed was as if the engine had accelerated as it downshifted causing the braking action to not be as good as it should have been. since i knew the car occasionally did this i thought i should report this as possibly contributing to my problem and put it on record in case you had other reports like this.
Service stabilitrak. abs nonfunctional or traction control. dealer claims power steering assist gear to be cause of issue. sounds like 2015 colorado recall issue
On november 24th 2017, while stopping to make a right turn, my 2016 extended cab, chevrolet colorado 4wd turned itself off. with the brakes not working and into the intersection of a 4 way stop, i put the gear in park to stop the vehicle. i restarted and everything was normal. no accident and no injuries. on november 28, 2017, on my way home from work, while driving straight in traffic on us /route 40 in maryland, my colorado turned itself off, brakes didn't work, resulting in rear ending the vehicle stopped in front of me. the brakes did not work, the air bags did not work (did not deploy). there was significant damage to my colorado, and i have chest bone (sternum) injuries.
I took my colorado in to dealership due to engine stalling, this is a very dangerous safety issue, i lose steering and braking ability when the engine stalls. the dealership said they are aware of the problem but they do not have an answer on how to fix this issue. the dealership informed me they have 4 other colorado's doing the exact same thing. also there are thousands of complaints on the internet of this exact same defect. i ask chevrolet to buy back my colorado due to it is not safe to drive. *js
Approaching an intersection and observed a yellow light. i was traveling 35mph as posted and applied the brakes only to have the pedal go all the way down to the fire wall. the truck had no braking power and only slowed to about 15mpg after applying for roughly 40-50 yards. i ended up running into the intersection collided with another vehicle that proceeded on green.
Driving at about 60 miles a hour and lost all power engine was running but going no were all light were lite on dash like you turn key on before starting thank god no one was coming the other way or the car behind me would have hit me. he was a good driver. shut it off and restarted it then it would run with all light on dash even brake light and anti skid light and it said on infro. running at reduced speed. drove to my home a slow speed it let me. shut it down let it sit a few min. restarted it still the same. shut it down for about ten mim. restarted it. seem to run ok but check engine light is till on now i afraid the will just reset it and say it is ok. and next time i won't be so lucky. it has 5500 miles on it. i did see my life before my eyes hopping it dose not happen to others. taking dealer tomorrow it happen at about 5pm 3/24/2016
