2017 CHEVROLET TAHOE Complaints

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving at 75 MPH, several unknown warning lights flashed on the instrument panel, and the vehicle briefly shut off, then restarted while still in motion. Later, while driving at 45 MPH and attempting to complete a turn, the vehicle inadvertently lost motive power. The contact was unable to pull to the shoulder of the roadway, but the vehicle was able to restart. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The stability control warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with the alternator and transmission. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was unknown.

Just over 115,xxx miles and the transmission is shuddering, difficulty with taking off, RPMs are not steady, delayed acceleration due to sputtering. When at signal light it acts as if it is not going to take off, which could cause other vehicles to rear end my vehicle. While on highway going speed limit these same symptoms occur which could cause multiple vehicle crashes. No service engine lights have come on, when attached to portable code reader, no codes were coming up. Vehicle has been serviced numerous time without concern, fluids were changed at recommended mileage. Problem has been confirmed by independent service center that the torque converter clutch is malfunctioning. Transmission is automatic, 6 spd, HMD, 6L-80

All of a sudden my transmission (6 speed) started slipping. No abuse /drag racing lol. Just normal driving. I limped into my local dealer and they said the transmission was “shot” and that they couldn’t let m drive it home. Also the transmission mechanic was outside smoking and I vape so I started a conversation with him about these 6 sp transmissions and he said “ I can’t count how many I’ve replaced” “ even with less than 80k miles. This is negligent at the least by Chevrolet to intstall dangerous and threatening transmissions. Bad Chevy BAD!

2017 Chevrolet Tahoe Brake Booster Vacuum Pump failed and had to be replaced. Booster sensor as well at cost of $1,493.22. Our vehicle almost hit another car in line for pre-school with children around and almost hit our garage doors due to this issue. Full recall in Canada but not USA? Why? "The amount of vacuum created by the vacuum pump may decrease over time. As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash"

The contact's brother owns a 2017 Chevrolet Tahoe. The contact stated that while driving 70 MPH, the check engine warning light illuminated, and the message "Reduced Engine Power" was displayed. Additionally, the vehicle decelerated to 20 MPH. The contact was able to pull to the side of the road. The contact stated that he turned on the hazards lights and continued driving 20 MPH. The contact stated that upon arriving to his residence, he connected an OBD reader to the vehicle and read diagnostic code P2138, which indicated an accelerator pedal sensor failure. The contact stated that he replaced the part himself; however, the failure persisted. The vehicle was taken to the dealer, where it was determined that there was water leaking inside the vehicle from the roof antenna mounting point, which caused the driver's side fuse box to rust, causing electrical failures. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

I just experienced an issue with my transmission, I was driving home from work in cruise control and started up a bridge when my vehicle seemed to disengage the clutch and start rapidly slowing down (I was going up the incline of the bridge) and the motor redlined trying to maintain speed. I immediately switched it back into regular drive mode and noticed that the engine was not engaging with the transmission. I then placed the column shift into the manual setting and dropped down to 3rd gear, the tahoe gave a really abrupt and hard impact on the transmission and I got it to reangage to continue up the incline. This happened more than a dozen times in the remaining 15 miles to my home, both in and out of the manual setting. I did not attempt to go back to curise control. When I got home I turned the car off and checked the trans fluid level and saw nothing on the dipstick, I let it cool off and I have fluid past the "hot" mark and into the S curve of the stick. I was able to determine that my transmission was having a majority of its issues beyone 3rd gear. After doing some very quick research on Google it appears that I'm not the only one having transmission issues, primarily with 3rd and 4th gear of this year make and model. Is this something that is being investigated? My vehicle has 103k miles and is planned for a fluid change in the next couple of weeks (transmission, transfer case, and rear differential), per the O&M book that came with the vehicle. This just happened today and I have not had an opportunity to reach out to the dealership to question them about it. There were no warning indicators or error messages during the drive or during the time this occurred. All recall notices have been repaired on the tahoe to date, and I have kept up with the other fluid changes and other misc o&m recommendations. Please, any feedback would be very appreciated as this is my primary and safest vehicle to transport my kids.

Transmission on my 2017 Chevy Tahoe failed and needs a complete replacement. I notice a class-action lawsuit has been filed for other Chevy models but the Tahoe was not include although it has the same transmission/gearbox. I was on a major interstate when the transmission failed causing the vehicle to decelerate. The car was towed to a Chevy dealership where they have confirmed the transmission needs to be replaced and this has been an ongoing issue with this vehicle. There were no warning lights prior. The check engine light came on after the transmission failed.

The brakes become very hard to engage while at a low speed, consistently in traffic and the car rider line at school. It has caused me to almost hit cars in front of me and people walking between cars. To me, it feels like the brakes are sticking and not releasing fully when I release the pedal to recoil and as if a line is going to be filled with pressurized air to work again and it is not able to do so. If i wait and let the cars go far ahead of me and the blast without using brakes, there isn’t a need to keep using the brake m, but this is not how to drive in traffic and it isn’t safe. It also is scary to not rely on the function of my brakes and it is putting people at risk every day I drop my kids off or kick them up from school. I have had the brakes evaluated for repair, but I am told there is no issue with the brake pads or roters. No warning lights. It resolved after having my brakes evaluated and tires replaced, but it has returned.

The power steering motor went out while I was driving. The message center on my dashboard alerted me just seconds before I couldn't steer. Luckily I was on a residential street and was able to get out of the road with a lot of effort steering. The car was taken to a local mechanic and we were told the power steering motor went out. The mechanic ordered the part and replaced it. The process took 3 weeks total to get the part, replace it and Chevy dealer reprogramming it.

Braking system becomes inoperable when the brakes are applied at the same time the forward collision system is engaged by the vehicles computer.
