2017 Chevrolet Tahoe

About 3 weeks ago my vehicle began shuddering during acceleration only at low speeds, and I had an appointment to regularly scheduled maintenance next week and planned to have the dealer look at it during that appointment. However, 3 days ago, at about 84,479 miles I was merging on to the highway and when I attempted to accelerate to highway speeds the tachometer jumped to 6000 rpm’s and became very sluggish when accelerating. It calmed down, but shortly after calming down, the tachometer spiked again to around 4500 rpm’s at 70mph, the check engine light came on and the vehicle temporarily stopped responding to any input except to raise the tachometer reading. After shifting into manual and back into automatic the transmission reengaged but would not allow for normal acceleration. The vehicle was able to be driven at approximately 30-35mph while the tachometer stayed consistently at around 3500-4000 rpm’s. The trouble codes given were P0700 and P0796, both relating to transmission indicating a problem with it.

On 5/5/2022, I was driving my 2017 Chevrolet Tahoe. I pulled into traffic and then traffic briefly stopped moving. When I attempted to accelerate, my truck would not move. When I tried to accelerate, my truck began to roll backwards into the traffic behind me. My truck would only move in reverse. A passerby left his vehicle to assist me with backing up off the road as much as I could due to there being a ditch next to where I was stranded. My husband attempted to back the truck out of the road completely but the truck then slid closer to the drainage ditch. Roadside assistance had to be called and my truck had to be winched out and towed to my home on a flatbed. There were no warning signs prior to this incident. There were no warning lamps, no messages, no unusual smells or sounds nor did it drive differently. The closest GM dealership was unable to assess my truck due to them being backlogged and not having any available appointments. The truck was taken to two separate mechanics that stated that I need a new transmission. One was able to do a diagnostic and stated that the code for speed sensor failure read after the 2nd attempt. When the truck was taken there for repair the speed sensor did not read but instead the main control valve body was the fault code. The repair was completed and two days later the truck would not shift between gears. I had to take my truck to another GM dealer 30 minutes away. They diagnosed my truck and stated that fault code for an irregularity in shift solenoid B showed and that there was metal shavings in the transmission fluid. I also have Onstar diagnostic checks that reported no transmission issues on 04/14/22 and 05/16/22 that there were no transmission issues as well. Now Gm is refusing to address my issues because of the mileage being over the warranty. I could have been seriously injured because my vehicle stopped in traffic with absolutely no warning signs.

Around 84,429 miles accelerated onto freeway and check engine light on and slow to accelerate. Try getting up to speed on an interstate without response when you slam on the gas. Went to shop, generic 700 code many things, but recommend to stop driving immediately. Continued to be be slow accelerating, changing my driving patterns to where I was not turning left unless with a turn light, or driving out of my way to make right turns ( to go Left). After a week (and calling shops) it had to be looked at and diagnosed. Took to transmission shop, Rebuilt was offered for quicker turn around, they could start ASAP. Their comment was we see a lot of this model and keep enough parts for this Tahoe to start. Also noted when dropped off 2 other models of this generation Tahoe were in the shop. And a GMC Sierra around the same period (assuming same Transmission here). Test Drive with Manager, they repair a lot of Chevy Tahoes and suburbans, and Nissans. Those keep them in business. Sister in law was there to get her Nissan Transmission Rebuilt about 3 months prior. (No Toyotas in the shop or Parking lot) I wish I had visited a Transmission shop before looking for new cars, great insight to prevent expensive repairs. After repair last week all is right (as expected when accelerating )This should be a recall at point or at least extend the warranty on the drivetrain and repairs. Just a thought with the complaints here and the Transmission shops. Should be looked at, not just on the 2017 model.

My wife usually drives the Tahoe for short day to day commuting to and from work and bringing kids to practice, but I needed it for work one day and upon trying to accelerate onto the highway I noticed the transmission had no power when accelerating. I took it to a Chevy dealer and they were unable to diagnose the problem due to it not displaying a check engine light nor were they able to guarantee they would be able to determine the problem if they kept it longer for further inspection. I made an appointment with a shop down the road and after an inspection and test drive, they were able to determine that gears 3 and 6 were shot on the transmission. and that the engine was at 100% load going 55 mph. After waiting 4 weeks for a transmission, when we went to pick up our vehicle, he had 2 other Tahoes in the shop (2016 and 2019 with 77,000 and 51000 miles respectively) both needing new transmissions and said he has had many Suburbans and Silverados with same problem around the same miles. Shame on Chevrolet.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving 65 MPH, the vehicle made an abnormal sound and would not accelerate. Additionally, the brakes failed to engage immediately while the brake pedal was depressed. The vehicle was taken to the dealer and diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The failure recurred with the gear shifter not shifting into Drive or Reverse. The manufacturer was made aware of the failure. The failure mileage was approximately 103,000.

4 days after getting an oil change, new tires, and a safety inspection I was driving to pick up my kids from school and my 2017 Tahoe stopped accelerating on the freeway. Was able to drive 15mph back to the mechanic who told me the transmission was shot. Needs a whole new transmission, estimated to be $6,000 and a 5 week delivery time. Not only that, mechanic said I’m the 3rd Chevy in the shop with the same problem waiting for a brand new transmission.

My Tahoe had been making bad noises for several days, no check engine light on. Was driving with my children and went to pull out onto US-127 and the car wouldn't go in drive. Then to get out of the road I couldn't even go in reverse putting me and my three children in danger. My Tahoe has 82,000 miles and is only 4 years old. The transmission has been confirmed by multiple Shops that is always the problem with these Tahoe's.

Vehicle was driving fine when parked. 12 hours later, I went to move it from my front driveway to the carport. It started fine and when I put it in drive and pressed the accellerater it wouldn’t move. I pressed it again and the vehicle jerked forward into my lawn causing me to brake hard. I put it in reverse and it backed up fine. Again, I put it in drive but it wouldnt go forward. It acted as if it was in neutral. I turned it off and tried again receiving the same results. Had it towed to dealership. Transmission flush performed but didn’t remedy the problem. Needs a total new transmission at 66,000 miles.

I was driving this vehicle in rush hour traffic and the check engine light came on and it suddenly lost power and wouldn't shift gears. I pulled off the road and placed the vehicle in park. At that moment I received an email from Chevy OnStar stating my transmission had a problem and to take it to the dealership. I had it towed to the dealer and was informed that the torque converted had failed and there were metal bits in the transmission fluid. The transmission had to be completely replaced to the tune of $6450.00. This vehicle has under 67K miles. There were no warnings prior to this incidence. This vehicle has been maintained at the prescribed GM service intervals.
