The contact owns a 2014 Chevrolet Silverado 2500. The contact stated while her husband was driving 45 MPH, several unknown warning lights illuminated, and the contact lost control of the vehicle. The driver was unable to shift gear. The driver stated that the vehicle hesitated and failed to accelerate over 20 MPH. The driver was able to continue driving to the residence. The vehicle was not drivable. The contact towed the vehicle to an independent mechanic, where the vehicle was diagnosed and determined that the transmission control module (TCM) needed to be replaced. The vehicle was not repaired due to the parts not being available. The contact called the local dealer and made them aware of the failure. The dealer informed the contact that parts were not available. The manufacturer had not been informed of the failure. The failure mileage was approximately 135,000.
The tcm malfunctioned. After being replaced the vehicle still didn't perform as it did before the repair. I have researched this issue with all Chevrolet trucks from various years. There are multiple blogs from owners of these trucks that show the extent of the issue. I cannot afford to pay $ $1000 to fix a problem that GM knows that has existed for years. This is a serious problem if you are driving and the truck looses power; especially when you're going down hill traveling at a high rate of speed and your transmission doesn't function properly. I have had the transmission repaired and the issue persists; it seems as though GM wants owners to pay out of pocket. Some may not and this could lead to unsafe trucks being on the road. Thank you.
Here's my story for those that will listen. I purchased the vehicle brand new and a few days later I mentioned to the salesman that it drove unusual and he replied that it could be from sitting on the lot...so I waited for the first scheduled maintenance and let them know that there was something not right with the shifting of the vehicle. I noted that it was loud clunking at downshift from 3rd to 2nd gear and also a clunk shift when the vehicle approaches a complete stop. The downshift is so hard that it is felt in the brake pedal. This is the part to me that raises the safety concern. The response was that they checked it and that everything was normal. I was informed that it should get smoother as it break in. They went on to say if I bring the vehicle in for the same issue and nothing is found that I would have to pay a diagnostic fee. So now at approx. 20,000 miles and I contacted General Motors. They agreed for more diagnostic and now there is a technical service bulletin that states that it is a normal characteristic of the vehicle. Now the vehicle has feels like it got worse and drives terrible and unsafe. Meanwhile there are complaints about this same problem on the internet and nobody has done anything about it. It's funny that 2016 Silverado is the same truck but without the problem. GM needs to make good on their productions mistake and support there product. Silverado drivers experiencing the same condition should complain to make manufacturers responsible. Please investigate!!!!!!!!!!!!
Transmission clunks on downshift(seems like 3rd to 2nd shift) loud enough that people think I ran over or hit something. Dealer says its normal and they all do it!
The contact owns a 2014 Chevrolet Silverado. The contact had not experienced a failure prior to having the vehicle repaired for a manufacturer recall concerning the 4 wheel drive function ability. Also, the engine control module was reprogrammed. Shortly after the repair by the dealer, the vehicle manually shifted into 4 wheel drive when in reverse or drive and would not disengage in inclement weather. In addition, the vehicle idled roughly, shuttered, and then stalled. The vehicle was towed to the dealer for further inspection and the battery was replaced. The dealer stated that there was a faulty ground connection under the dash panel. The ground surface was cleaned and the wiring was re-grounded. The manufacturer was notified.

Vehicle vibrates at 72-80 mph. Have taken it to the dealer 4 times with no positive results. They rf balanced all tires twice, replaced one tire, and on the last visit drove it 95 miles and did nothing. Currently dealing with GM customer care rep and dealership. If they cannot find a fix, I will request they buy the vehicle back.
The contact owns a 2014 Chevrolet Silverado. After switching gears into the drive position, the vehicle jerked forward while the brake pedal was depressed without warning. The contact mentioned that the failure occurred only when the vehicle was switched from the reverse position to the drive position. The vehicle was taken to a dealer but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 10,000. The VIN was not available.
While driving down the highway a stabilization control light came on briefly, then went away. Approximately 5 miles later after exiting the highway, and going down a side street, the truck died and the steering wheel locked when I slowed and started to make a right hand turn into a parking lot. This has since occurred once more under similar conditions while slowing, braking and turning at low speeds and not under throttle.
I started having problems with the electrical in the truck starting with the windows. I informed dealership and that the stabilitrak was going off saying that the steering was failing. The problem has continued to present and now the truck is shutting itself off while going down the road losing all steering and turning itself back on. My family was in the truck and we almost rolled into a parking structure, I lost all power and steering to truck had no control at all. The truck continues to have issues and this after I took it in to have it fixed. Dealer made problem worse.
I began to notice severe vibration in the drive train at 55 mph, similar to a washboard effect. In addition, the vehicle down shifted very hard when stopping. I reported this problem to the dealer on this date and they said it was normal operation. In December, of 2014, I tried passing a vehicle and experienced a loud thump in the rear end of the vehicle, I thought the drive shaft was going to fall out. I took the vehicle to the dealer and they could not replicate the issue. I have taken the vehicle to two different dealerships a total of 3 times to address this issue. They both claim this is normal. Now the vibration has gotten worse, it can occur at 40-45, 50-55, and 60 to 65. I have owned GM trucks before and the only time I had an issue like this was when the drive shaft on a 1994 safari van was out of balance had to be re balanced. I have noted several other complaints from other 2014 -15 vehicle owners. This type of operation has to be damaging the gears and transmission. I have called the GM area rep and got an attitude from him. However, I do have another appointment with the selling dealer, (3rd with him, 4th over all) this week. And was told to call the GM rep when I arrive.
The contact owns a 2014 Chevrolet Silverado. While driving various speeds, the vehicle began to vibrate violently. In addition, the accelerator pedal was depressed and the vehicle continued to vibrate. The failure recurred on numerous occasions. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 100.
I was merging onto the highway and just about got up to speed and felt a vibration that within a few seconds got really intense then heard a pop and then several bangs. I thought a tire blew, so as I looked up in my rear view mirror to see if I was clear to get over to the shoulder, I saw my driveshaft cartwheeling about 8 ft. In the air as people behind me were scrambling to avoid from hitting it. Luckily the driveshaft didn't lift the back of the truck into the air, and more importantly it didn't go through someones windshield behind me! it turns out that the knuckle on the rear of the shaft had snapped, violently vibrated and the shaft dropped, ripped apart about a foot behind the transmission and came out from under the truck. The U-joint was still in the differential and a foot of driveshaft was still in the transmission. I had brought my truck to 2 different dealerships for a vibration and clunking noise in the rear when it was new, (1900 miles) both dealers told me "they couldn't duplicate customers concern"...I'm a mechanic, I've worked at dealerships, this is what they tell people when they don't want the headache of dealing with an issue. After looking driveshaft vibrations up on these specific trucks, I came to realize that it is a common problem with 2014 and 2015 GM full size trucks. This incident could have turned out much worse than it did...if you own one of these trucks and notice a vibration at all, get it into the dealer and get it fixed immediately, don't take the chance of hurting your family or someone else!
The above stated vehicle was sold to me, and I was allowed to leave with this vehicle before a recall that had been issued June 26 2014 had been remedied. ( sale and delivery of an unremedied recalled vehicle). Upon reporting to the salesman about the recall, he and his salesmanager stated to me that there was no recall on the vehicle. I checked with the nthsa found the recall and had it fixed May 5, 2015. After asking the salesman why my vehicle had not been fixed during the 6 months prior to the sale of the vehicle to me, his answer was that the vehicle had previously sold in July of 2014. The buyer had the truck for 7 days and could not aquire financing and the vehicle was returned. Hence this one vehicle has been sold and allowed to leave their lot twice without the recall being fixed. The dealer is norman frede Chevrolet in houston tx.
The above stated vehicle was sold to me in Dec. 2014, and I was allowed to leave with the vehicle without knowing the vehicle was under recall. (sale and delivery on an unremedied recalled vehicle). The recall for this vehicle had been issued June 26, 2014. When I asked the salesman about this recall, he stated to me he had ckecked with his salesmanager and that there was no recall on this vehicle. After checking with the nthsa database and found the recall, I had it fixed on May 5, 2015. I asked the salesman why my vehicle had not been fixed during the 6 months prior to the sell to me, his reply was that the vehicle had been sold in July of 2014 and that the buyer had the vehicle for 7 days and returned it for lack of funds. That means they sold this vehicle twice while the recall was unremedied.
I purchased the 2014 Chevy Silverado crew cab lt Texas edition from reliable Chevrolet in richardson, tx. Immediately after purchasing without a test drive it noticed that there was a vibration, steering problem, and scratches on the bed.. because it was a demo of was told by the new car salesman that they had made sure the vehicle was inspected and that the scratches were superficial and it's a demo so that's how it is. I spoke with the business manager and they put a spay in bed liner to fix the scratches and did a balance on the tire. I picked the truck up and the steering and vibration problems were still there. It went back into the shop again and they couldn't duplicate any problems. The steering is almost impossible to keep in a straight line it swerves as if the truck had a few drinks. I told them it don't feel safe driving it and I'm afraid I'm going to hit someone. I will not drive in the middle lanes. I have to drive on either far left or right lanes to allow for swerving. I complained to GM.. got excited because they sent me to another dealership and same thing happened.. went for a test drive.. they felt something wrong but mechanics can't "duplicate" the problem. They said they test drove it again but in don't see how when the roads were iced over. I called GM again and I'm at a new dealership they test drove it with me and headed a new popping noise when the wheels is turned and felt steering and suspension issue. They kept the truck but once again not able to duplicate. I've had a few loaners and none of them drive like mine. The truck has also had problems with ac and whiny noise in engine. I'm was supposed to pick up the truck today but I complained and they were going to test drive it again. They don't factor in the time and inconvenience of having to take off work plus gas and miles in trying to get this fixed. Not happy with this truck.
Shifted truck into reverse while plowing my driveway, truck made a large snap sound in front end and wouldn't move - oil was dispersed all over the ground. In the end - front yoke broke, causing drive shaft to hit oil filter and busting it off. Truck was under warranty so no cost but this is dangerous. Had I been moving this could have caused a truck to flip end for end.
