No one expects that a truck is going to provide the smoothest ride around, but today’s technology has made it better than ever. Many trucks now offer smooth-shifting, reliable power. Unfortunately, complaints regarding the 2018 Chevy Silverado suggest otherwise about this truck.
One driver took to Edmunds to make this statement regarding their experience. “Before it had 500 miles on it, I could tell something wasn’t right. The 1st to 2nd and 2nd to 3rd shift had a hesitation and was sloppy. At speeds 25 to 45 mph it felt like it would miss or shudder, not terrible but I could feel it. In the mornings it would idle at 1100 rpm, and run terrible for the first several miles. I took it to the local Chevy dealer and we drove it, they told me the transmission had to ‘learn’ my driving style and it might take 2000 miles before it would improve. After some investigation on the internet, I found there was a lot of people with 2016 and 2017 with the same problems; GM actually has a name for it ‘chuggle and fish bite.’ I called GM and opened a complaint but basically got the runaround. At 2000 miles, I took it back to the dealership armed with service bulletin numbers for the 2017 that were giving trouble. They drove it and said there was a problem with the way it shifted but because the TCM service bulletins were for 2017 and my truck is a 2018 they couldn’t perform those updates. But there was another ECM update and they did that and it shifted better. Bottom line is my truck doesn’t run right. I have tried to call the GM customer service rep I have talked to last, he gave me his extension number. But I have left two messages and he hasn’t called me back.”
There are numerous Service Bulletins issued from the company regarding the powertrain concerns. Service Bulletin #PIP5531 relates to stalling shudder, hard shifting and reverse vibration. In this situation, technicians are asked to evaluate excessive crankshaft end play and inspect the crankshaft bearings.
In Service Bulletin #17-NA-228, the automaker refers to a clicking or ticking noise on 3-4 shift with trucks that have a six-speed Allison automatic transmission. With this issue, Chevy claims it is a normal characteristic and doesn’t require any repair. They also claim it won’t affect the longevity of the transmission. So, what they are really telling consumers is that it doesn’t matter what noises or weird sounds come from your truck, it’s completely normal. Believe it or not, some people think that’s actually true.
Here are some actual complaints logged with the NHTSA about the 2018 Chevy Silverado Transmission Problems:
PARKED AND SHUT OFF, DISCONNECTED TRAILER. TRUCK ROLLED BACK WHILE IN PARK. I JUMPED OUT OF WAY AND TRIED TO OPEN DOOR TO STOP. DOOR KNOCKED ME DOWN AND CONTINUED BACKWARDS DRAGGING ME. FINAL STOP OVER EDGE OF POND AGAINST TREE STUMP. HAD TOWED TO DEALER FOR INSPECTION BY CHEVY ENGINEER. 2 WEEKS NO COMMUNICATION.
THIS TRUCKS TRANSMISSION SHIFTS WHENEVER IT WANTS TO… I WAS DRIVING 45MPH AND COASTING TO A RED LIGHT WHEN IT DOWNSHIFTS HARD BUT WHEN THE LIGHT TURNED GREEN AGAIN AND I PRESSED THE ACCELERATOR I HAD NO TORQUE, LIKE I WAS IN 5TH GEAR AND SHOULD HAVE BEEN IN 2ND. I PRESSED A BIT HARDER AND IT DOWNSHIFTED HARD AGAIN AND WAS AT 5K RPMS! I THOUGHT IT HAD AN 8 SPEED TRANSMISSION, BUT IT SURE DOESNT SEEM LIKE IT. MY TRUCK WAS NEW AND ONLY HAS 5K MILES ON IT. UNACCEPTABLE
THE TRANSMISSION SLIPS OR SHUDDER, ALSO HAS FREE WHEELED WHEN GOING DOWN HILL AT SLOW SPEEDS, ALSO OCCURS IN REVERSE, USUALLY ABOUT 1 TO 2 CAR LENGTHS. HAVE RETURNED TO THE DEALER SEVERAL TIMES AND BEEN TOLD THAT GM DOES NOT HAVE A REMEDY. HAD THE SERVICE RECOMMENDATION OF A TRANSMISSION FLUID FLUSH DONE TWICE WITH DIFFERENT FLUID INSTALLED WITH NO CHANGE. HAS BEEN IN THE DEALERS SHOP FOR 3 WEEKS WITH GM LOOKING AT THE PROBLEM, NO SOLUTION IN SIGHT. NO CONFIDENCE THAT GM CAN FIX THE PROBLEM. THIS COULD DEVELOP INTO A SERIOUS SAFETY ISSUE.
If you thought the noises and vibration ended at the powertrain, you would be wrong. The suspension seems to have just as many complaints about the ride it provides. It seems no matter which way you look at it; the Chevy Silverado can’t seem to offer a smooth, comfortable drive.
One owner on Edmunds wrote, “$50,000 truck that vibrates, shifts bad, drives terrible, jumps and jerks. And the dealer says it’s the way the truck should drive. I have owned 3 trucks and a Suburban with the same motor and transmission and none of them drove like this piece of junk. Dealer says you cannot compare them??? All kind of complaints on same issue but GM has done nothing.”
Again, there are multiple Service Bulletins from the automaker addressing concerns with the suspension. Bulletin #PIT5049E refers to the rattle, squeak, clunk, thump and bump noises coming out of the front suspension. In this correspondence, the automaker recommends looking to the opposite side of the noise to find the root cause, but there is no suggestion on how to repair it.
In Service Bulletin #PIT5533B, GM refers to another creak, click, pop or crack-type noise coming from the front suspension during turns. It appears that it happens more often while making a tight turn and can often be felt in the footwell region. The root cause appears to be insufficient torque of the front frame crossmember or lower control arm bolts. To fix it, the technicians must loosen and re-torque the four front frame crossmember bolts and nuts plus the front lower control arm mounting bolts and nuts. Despite Chevy’s claims, we still don’t see the dependability they are referring to; unless you consider loud, annoying noises as a sign of reliability.
Here are some actual complaints logged with the NHTSA about the 2018 Chevy Silverado Suspension Problems:
TL* THE CONTACT OWNS A 2018 CHEVROLET SILVERADO 1500. WHILE DRIVING VARIOUS SPEEDS, THE STEERING WHEEL, ACCELERATOR PEDAL, AND CENTER CONSOLE EXPERIENCED EXCESSIVE VIBRATION. THE VEHICLE WAS TAKEN TO COUNTRY CHEVROLET (11 E. LEE HWY, WARRENTON, VA), BUT THE CAUSE OF THE FAILURE WAS UNABLE TO BE DETERMINED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 200.
STARTED TO HEAR CLUNKING NOISE AROUND 15,000 MILES. THE NOISE STARTED TO GET WORSE AS TIME WENT BY. FIRST IT WAS JUST WHEN DRIVING UP MY DRIVEWAY THEN IT WAS WHILE DRIVING OR EVEN STATIONARY PUSHING DOWN ON THE REAR BUMPER. FOUND THAT THE LEAF SPRINGS WERE CRACKED BUT IT WASN’T VISIBLE WHILE THEY WERE ON THE VEHICLE.
Up until now, we’ve dealt with a lot of issues regarding the ride and comfort, but the steering concerns take us to another level. No one wants to deal with steering problems as it leads to anxiety and fear while driving down the road. Still, Silverado owners find themselves wondering why they have so many issues with the steering column.
One owner went to Edmunds to vent frustrations. The review says, “Bought this truck 9 months ago has been in the shop 32 days for work since I bought it. It’s a daily driver for the road to work and home so not abused at all. First, it took them forever to figure out where the cab noise is coming from then when they did, it was the boot for the steering column, I have had the truck back a month and less than 500 miles and it’s back again. Come to find out that is a common problem with this boot and its defective. My truck is a 2018 same look, model, style and the 2016, 2017, 2018 and they still refuse to design a new boot to fix the issue and keep replacing it with the same defective existing piece. My truck goes back on Monday for the exact same issue again.”
GM issued Service Bulletin #PIT5565A which addresses a squeaking and squawking noise while turning the steering wheel. The root cause stems from the lack of lubrication in the shaft where it passes through the engine bulkhead I-shaft boot. To repair it, techs must apply lithium based grease where the I-shaft touches the rubber boot. Too bad there’s no way to put grease all over the truck to reduce all the crazy noises and sounds coming from it.
