Incident

Jan 20, 2023

Beginning in 2018, perhaps earlier, I noticed that often when I would press the accelerator all the way, the engine would (and still does) make a sound (I’ve since learned, through many dealership interactions and internet searches, that the sound is referred as pinging or knocking from pre-detonation), and it SEEMED that the car’s computer would (and still does) electronically back off the throttle, and the rpm’s reduced in terms of speed of acceleration (sometimes the rpm’s even DECREASED as opposed to merely increasing less rapidly). This has placed myself and passengers of the car in danger by causing the car to go through intersections significantly slower than I (as well as my mother who also occasionally drives the car) would naturally anticipate, as this slow crossing through the intersection has led to many close-calls when intersecting traffic (when they have the right-of-way) almost crash into the broad side of the truck. It USED to occur I would put in any fuel with an octane rating lower than 91, but now it even happens with 91 octane fuel. The problem has been reproduced by two Chevrolet dealerships. I have taken it in many times to have them repair/replace/service parts that I thought might be causing the problem. The shop foreman at one location replicated it and said he had no idea what the cause could be. The service dept. was then in back-and-forth contact with engineers at GM over the next couple of days, and the engineers eventually suggested an oil system flush thing (which ended up not helping). It’s had oil filter changes, fuel induction service, and basically everything short of replacing the injectors or pistons. Neither the vehicle nor its components have been inspected by the manufacturer, police, insurance representatives or others. No warning lamps or messages have ever displayed in relation to the problem. My co-worker’s husband has a 2018 GMC Canyon with a V6, and says the exact same thing happens with his car.

I called Chevrolet and they told me to call dealer but I had no luck. My 2015 Colorado truck is parked on my driveway for the last 2 months.

My 2015 Chevrolet Colorado with a v6 engine has corroded oil cooler lines. I have scheduled a repair appointment with my local chevrolet dealer. I believe this is a common problem with this vehicle. There are many incidents of similar problems with these corroded oil cooler lines. Also, my mechanic has seen this problem on many other Colorado trucks with v6 engines.

HESITATES DURING ACCELERATION. I HAVE REVIEWED NUMEROUS COMPLAINTS ONLINE WITH SIMILAR COMPLAINTS. WHEN ACCELERATING FROM A STOPPED POSITION THE ENGINE HESITATES AROUND 2000 RPM. IT HESITATES TO A POINT WHERE IT IS A SAFETY ISSUE. HOW MANY COMPLAINTS HAVE TO BE RECEIVED BEFORE NHSTA ACTS? IT HAS BEEN LIKE THIS SINCE I HAVE OWNED IT. TOOK IT TO THE DEALER - INITIALLY THEY SAID THERE WAS A COMPUTER PATCH. STILL HESITATING.

PURCHASED 2015 COLORADO JULY 2015.WE HAD IT IN FOR OIL CHANGES & A FEW TIMES REGARDING HESITATION OF ACCELERATION. SERVICE TECHS DID NOT TYPE COMPLAINT WHEN IN FOR OIL CHANGE ONLY WHEN BROUGHT IN SPECIFICALLY FOR ACCELERATION ISSUE. THEY STATED IT WAS OUR FAULT WE DID NOT READ THE WORK ORDER.IT IS NOT MY JOB TO READ A WORK ORDER IT'S THE SERVICE TECHS JOB TO ENTER EVERY COMPLAINT OR ISSUE ADDRESSED BY THE CUSTOMER. THE LAST SERVICE WAS WHEN I SPOKE TO SALES MANAGER WHO SET ME UP WITH SERVICE MANAGER & I WAS ASSURED ME A TECH WOULD DRIVE VEHICLE FOR A WEEK TO AND FROM DEALERSHIP APPROX 40 MILES PER DAY SO THEY COULD DIAGNOSE THE ISSUES.I HAD ADVISED ISSUE IS INTERMITTENT; THE REASON THEY COULD NEVER DUPLICATE WHILE IN FOR SERVICE. THEY MADE SURE TO STATE IT WAS RUNNING TO MANUFACTURER SPECS. THEY DROVE IT 10 MILES NOT 40 MILES A DAY FOR THE 7 DAYS THEY HAD IT.THEN SAID EXACTLY THAT IT WAS RUNNING TO MANUFACTURER SPECS. OF COURSE IT DID, YOU DID NOT DO WHAT YOU PROMISED WASTING MY TIME & KEPT MY VEHICLE FOR 7 DAYS JUST TO PACIFY ME. I TOLD THE SALES MANAGER WHAT HAPPENED WHO I PURCHASED THE 2015 COLORADO & MY 2014 CAMARO THAT I WOULD NEVER BUY ANOTHER CHEVY PRODUCT AS THEY WOULD NOT STAND BY THIS ISSUE, THEIR CUSTOMER OR THE LEMON LAW. TODAY MY HUSBAND IS IN AUSTIN TEXAS WITH HIS TRUCK IN THE SHOP AGAIN AS TRUCK NOW HAS A SERVICE ENGINE LIGHT ON; OF COURSE STILL HAS THE ACCELERATION ISSUES AS THAT WAS NEVER ADDRESSED OR FIXED.WE HAVE TO PAY $800.00 TO FIX ENGINE ISSUES ON A 2015 VEHICLE, THIS TIME NO WARRANTY EVEN THOUGH WE THOUGHT WE WERE GIVEN A 75K WARRANTY WHEN WE PURCHASED THE VEHICLE. THIS IS THE ONLY THING I CAN THINK OF DOING PRIOR TO RETAINING AN ATTORNEY TO FIGHT FOR THE LEMON LAW FOR A VEHICLE WE BOUGHT FOR 40K. WE HAVE HAD ISSUES WITH THIS VEHICLE SINCE PURCHASE & I AM HOPING I WILL GET A CALL FROM SOMEONE FROM THE NHTSA REGARDING THIS COMPLAINT!

WHEN GOING JUST 5 MINUTES UP THE ROAD AND STOPPED AT A TRAFFIC LIGHT, THE ENGINE STUTTERS, THEN SHUTS OFF. THERE ARE NO WARNING LIGHTS THAT COME ON WHEN THIS HAPPENS. IN JUST ONE WEEK, IT HAS HAPPENED TWICE. I HAVE REPORTED THE ENGINE STUTTERING BEFORE AND THE MECHANICS COULD NOT FIND ANYTHING WRONG WITH IT. I DRIVE AN HOUR TO WORK EACH DAY AND THIS IS VERY UNSAFE. I DRIVE THROUGH HEAVY TRAFFIC EACH DAY AND I AM AFRAID I WILL GET INTO AN ACCIDENT IF THIS CONTINUES TO DO THIS. I HAVE OWNED THIS VEHICLE FOR ONLY 10 MONTHS. THIS IS VERY SAD. I THOUGHT IT WAS THE OIL OR "BAD GASOLINE".

COLORADO HAS A GREAT DEAL OF HESITATION AT LOW SPEED WHEN ACCELERATION IS APPLIED. VEHICLE LURCHES, SHRUGS, SPARK KNOCKS, HAS DELAYED THROTTLE RESPONSE....SEEMS TO "CHUG" UNTIL A HEAVY THROTTLE IS APPLIED, THEN THE VEHICLE "JUMPS" TO A GEAR/RPM. VERY DANGEROUS WHEN TRYING TO ACCELERATE NORMALLY AND "GET OUT OF THE WAY" OF OTHER TRAFFIC OR JUST CLIMB A SLIGHT INCLINE. CHEVROLET DEALERSHIP SAYS THIS IS "NORMAL". THIS MAY BE NORMAL FOR CHEVROLET, BUT IT CERTAINLY IS NOT ACCEPTABLE FOR THE CONSUMER THAT WANTS A RESPONSIVE THROTTLE WHEN ACCELERATION IS REQUIRED...... THIS HAS BEEN AN ON-GOING ISSUE WITH THE TRUCK SINCE IT WAS PURCHASED NEW IN APRIL 2015.
