2017 CHEVROLET SUBURBAN Complaints

At 105000 miles the torque converter on the 6L80 transmission failed. I am having my transmission rebuilt.

antilock brake system makes it hard to press brakes mostly traveling at lower speed like when i’m parking. previously had it reprogrammed because of a recall but it continues to have this issue periodically. now i’m being told I need to replace to brake vacuum?

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission had a failure. The torque converter along with a valve assembly failed which caused metal to go everywhere inside of the transmission case. Per the transmission shop that completed the rebuild, they have seen this exact problem numerous times before and have fixed it. Rebuilt kit included cooling bypass, billet torque converter and other parts to rebuild transmission. Vehicle only had 85K miles on it and is a 2017. Price to rebuild was $4000, and dealership quoted almost $6000 for a reman. How was your safety or the safety of others put at risk? Vehicle transmission disengaged while attempting to merge into traffic on busy road. Vehicle was stuck in middle of intersection with 3 small children in the back while vehicles were passing at high rates of speed on a 45mph limit roadway. The vehicle was unable to be safely moved until good Samaritans were able to push the vehicle in neutral to the side of the roadway. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle transmission was inspected by both a local Southern NV Chevy dealership as well as a Transmission shop and was confirmed to need replacement due to the damage from the vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The parts that were removed from the vehicle were not inspected by any of the above parties. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No error codes or MILs were present before, during, or after the transmissions failure. Repair invoice available upon request.

Hi, there! I know a few people that have the same car as me Suburban/Yukon/Tahoe and everyone had to replace their transmission. My car has about 78K miles on it and I need to replace the transmission as well. It jerks really bad. When I press the gas pedal it doesn't move for like 2 - 3 seconds, but after that, it takes off like crazy. It seems very unsafe to me. Please look into it.

When I’m parking the car back and forth brake gets very hard to press and hard to stop and also after turning off trying to start but having hard time because of the brake is not applicable I have to press very hard These are the problems I have Thank you

The transmission jerks a lot, especially when taking off. I know 4 more people that drive a Suburban, Silverado, and Yukon, and all of them had to change the transmission before 100k miles. The dealer doesn't want to fix it, cause the warranty expired, but how is it fair for us consumers to pay 60k for a car that only lasts 5 years? When I called the dealer, even the technician agreed that they have a lot of problems with the transmission and are booked a few weeks ahead just to take a look at it. Please advise. Thank you.

The contact owns a 2017 Chevrolet Suburban. The contact stated while driving 5-10 MPH, the vehicle was jerking and there was friction in the vehicle motion. There was no warning light illuminated. Additionally, the contact stated that the vehicle would emit abnormal sounds while driving. The contact stated after the vehicle had jerked 4-5 times on the same occasion the vehicle would operate as needed. The vehicle was taken to the local dealer who diagnosed that no issues were found. However, the failure reoccurred. The vehicle was taken back to the dealer who diagnosed that the transmission fluid was dirty, had a burnt smell, and there were metal fragments in the transmission fluid. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 95,000. The VIN was not available.

On June 1st, we dropped off our 2017 Suburban Premier at the GM dealer. The suburban was had suspension issues, it was no longer safe to operate. Just before noon, the service advisor called to inform me that both struts and shocks were bad. If I wanted to proceed, repairs would be $4045.67. When asked how this was possible, I was told they hadn't seen this before. They thought this was odd, too. I was told it is common for their to be issues with this type of suspension, but they hadn't seen all of them have issues. I asked about policy assistance from GM, was told to file a claim with the manufacture after paying for repairs. With invoice in hand, I searched the parts online. I found I could buy the shocks and struts directly from GM for $451.14 ea, yet the dealership charged me $831.60ea. We paid the dealership $380.46 more for each part - totaling $1521.84 in dealer markup. I reached out to GM Customer Service on June 1st, opening case# 9-7845670653. I scanned and emailed the invoice and was told it was being send to the next level for review. In the five weeks since this started, I have called GM Customer service seven times and have sent six emails. I have received two emails and two calls. I've been told many different stories by many different people. I was told approval takes two days, then told it would take 14 days, followed with an internal approval problem. In the end, I was told it was a maintenance issue and GM would not be doing anything about. This is a huge safety issue! I no longer feel comfortable or safe in our suburban. I know that I am not alone in this issue, there are complaints of this every where you turn. This is a safety issue, GM should be issuing a recall or extending the warranty on these items. GM should be embarrassed, this is unacceptable!
