Hello, While driving my Chevy suburban last week as I was pumping gas with my two year old son in the back seat. I saw smoke leaking and rolling out from the bottom of my vehicle. I had shift the vehicle off and inspected thoroughly. I couldn't see and understand where this was coming from. It wasn't the engine block and no check engine lights had come on. So I let the vehicle cool and started her up. No issue until I was a mile or two from my family summer rental and all of a sudden the vehicle felt as though it slipped out of gear. I was left without any power and realized I was smoking again. I pulled or what I would call drifted to the break down lane and pulled my little man out of the vehicle. This happened on Saturday and after almost a week in the shop, the dealership sprung me a nice $5200 price for a transmission. …
The drivers seat back is extremely lose. Moves forward and back with every brake and acceleration. The seat base also moves slightly, rocking left to right in turns. The suspension completely failed and had to be replaced. An unknown oily substance has been coating the inside of the windshield since the purchase of vehicle in 2015. Requires constant deep cleaning in order to see through windshield.

I brought my 2015 Suburban ltz (63,000) into the dealership today for a horrible banging in the front passenger's side and was having a hard time controlling the vehicle when I hit a bump or pot holes. At first the customer service rep told us they could not replicate the issue and after some firm convincing, the tech came back and said that the shocks were indeed leaking in the front. While I have an extended warranty good for 72 months or up to 75K miles and the part is listed as struts under he GM code, the cost is not going to be covered and we are going to have to pay nearly $1800 to repair. We really have no choice but to repair given the noise is not only loud when the car hits a bump but also the performance and handling has not been great since the noise started. After researching it is very apparent that this is a known issue with GM! Why isn't the NHTSA looking into this? …
I have a 2015 Suburban ltz and the "magnetic ride" shocks and struts have failed completely. I have almost wrecked this vehicle numerous times due to the uncontrollable bouncing when you hit a bump. It is not an option at this point for me to pay $1500-$3000 for repairs when I already pay $700 a month for a payment. Online there are masses of complaints about this same matter! I spoke with the Chevrolet dealer in jasper, alabama today and I was told that they have had to replace multiple ones in the past few months. I have owned 6 Suburban's including this one and I usually put 200K on every one without any problems! This is the 2nd major malfunction that this truck has had and GM does not want to help out at all!! This vehicle is a safety hazard to drive and I have no choice but to continue driving it. GM changed to shocks and struts on the 2017 because of this problem.
Yesterday after bouncing all over the road for months and to the point of being unsafe to drive I took the SUV to the dealership only to be told I need 2 new shocks on the front end ($1680). When you spend over $70K on an SUV and just a few years later you need new shocks means clearly something is seriously wrong with the vehicle. After looking around I was correct it is due to a failed magnetic ride system which Chevy is aware of and choosing to do nothing. Shame on Chevy for doing nothing and ignoring the impact to the customer. This will be the last Chevy I ever buy. At least some compensation would be great but the dealership doing the work said no since Chevy does not recognize the defect. Front shocks/struts failed at 63,000 miles. Even with an extended warranty you are basically out of luck.
Front & rear of car shakes like a dump truck. Had inspection done at a local shop, since GM dealer found nothing. The sway bar frame brackets are coming loose causing excessive vibration & rattling. The truck also handles very poorly, along with the comfort of ride. GM is aware of the problem since there are so many vehicles with this same problem. They want us to pay for another inspection to determine if they will do anything. They will not discuss the repair or the cost associated with the repair if they deem it a needed repair. The TSB # is 15-na-082, yet they claim that this is not a good number. Searching the net reveals there are many affected vehicles built from 2009 to 2017 with the affected problem.
Have had our vehicle in the dealership 3 times for road/tire vibration from ?tires or suspension. Dealership has changed 3 of 4 tires could not get road forced balances with 22 inch tires. Dealership claims bad batch of tires from Bridgestone. Vibration has continued at speeds of 70-80 MPH. It all began after the first service at 5792 mile and tire rotation. Vehicle was brought back to dealership advising of vibration in steering wheel and both front seats. Dealership claimed that they were not able to get tires balanced. Had to order 3 different sets of replacement tires with no prevail. Brought back again for second required service and dealership has rotated the tires for a second time.
When traveling at interstate highway speeds vehicle had shaking, shimmying, vibration and buffeting as well as loud hum and wind noise causing nausea resulting in nausea and dizziness to the driver. This was worse on new macadam and on grooved highway but occurred intermittently on other surfaces, I just purchased this vehicle used and it is certified. I was unaware that this is a common issue and understand now that there is no recall to fix this and that GM has not found a permanent solution to the problem. The vehicle was also exhausting to drive on the highway because of the aforementioned issues.
