All driver assist functions failing

Air ride suspension going out, shocks leaking. Do not have stability of car.

- Blacksburg, SC, USA

Front shocks failed 2 years ago. Rear shocks just failed last week. Both of these failures affect the vehicle handling. The vehicle was inspected and failures confirmed by an independent service center. Both front and rear shocks had to be replaced. The complexity of the parts and system make these repairs costly. It cost thousands of dollars for each repair. It is a $70K vehicle and was manufactured in 2015. These should not be failing so quickly. And the repair shop said this is a know issue with the Tahoe of those model years but there is not an active recall. Someone needs to investigate how many of these Tahoes have had to have the shocks replaced.

The 2015 Tahoe LZ is experiencing harsh ride due to the failure of the factory Air Ride system. This may have been a good idea, but it will not stand up under normal road conditions. There is no recall for this problem. Shocks leak or are bound up (frozen in place) causing bumps to be transmitted to the vehicle body. I have changed tires and the problem is still there. I have driven GM vehicles all my life (70+years) and this is the most trouble I have ever experienced with suspension components of all the GM vehicles I've owned, starting with a 1955 vehicle. A local dealer priced the repair at around $5000. I drove a 1983 Suburban for over 300,000 miles and never had any suspension problems, (except for normal brake wear). There seems to be a lot of owners of this vintage vehicle that have experienced this problem. Whether this is a computer problem or poor workmanship, General Motors needs to REPAIR their self-inflected problem. I worked as a line mechanic for a GM dealership in the early 80's. We never had this kind of problems before computers started to be installed on vehicles.

My magna ride suspension has completely gone out. The front and rear are sagging with no suspension travel at all. According to Google, every Chevrolet and GMC with this suspension has the same issue. Cost $3000 to repair.

- West Monroe, LA, USA

2015 Tahoe with a very stiff ride. ASE certified mechanic who uses OEM parts says front struts and rear shocks are frozen and have to be replaced. Cost is $3600 and he says all parts are on backorder as this is a common failure. The ride is so firm that the car leaves the ground when riding over bumpy roads.

- Potomac, MD, USA

Front and rear shocks had to be completely replaced. 2 weeks later the transmission completely went out and have to be replaced. This vehicle has only 80,000 miles.

I own a 2015 Chevy Tahoe ltz which I bought less than a year ago and after several months I noticed that it handles bumps poorly and does a lot of bouncing. When I had new tires put on the service tech mentioned how poorly it drives and said the struts would need replacing on the front for sure and eventually on the back as well. I received my first quote at $2200 just for the front which is insane so I decided to do a little research and quickly found it this is a very common problem for this vehicle. I am very displeased with finding out this information for spending the amount of money I did on this luxury vehicle. I've price shopped around and have not found anything any cheaper. I am also worried if I let it go for too long what could potentially happen and will it lessen the life of the very expensive brand new tires I just put on. This is ridiculous and Chevrolet/GM needs to do something to make this right.

The shocks/struts began leaking and are faulty. They needed to be replaced. The cost of the repair was over $3,000 because they are a special type. The garage that did the work said he talked to other dealers/garages and those are well known for going bad on the 2015 Tahoe. A $70,000 vehicle should not need shocks/struts replaced within 5 years. And this vehicle has 15 recalls already. Can't this be classified as a lemon or something? this is ridiculous. And waste of my time and money to get all this stuff fixed. Thank you.

My 2015 Tahoe ltz has a very rough ride, it bounces and now there is a noise in the front end while in motion, and after having a diagnostic it has been found that my right strut has leaked fluid and has to be replaced. I find it funny that this is the most expensive vehicle I have ever purchased, and it has been in for recalls more than any other vehicle I ever owned. You pay somewhere in the sum of $63,000 for a luxury vehicle, you expect more from Chevy than not to have the problems I have had. It just doesn't seem fair.

It's rides like a horse buggy very rough feel ever bumps in the road hadn't had it long road good when we bought it. Sometimes the brakes seen to be sluggish, all this happen on a trip to the mountains

- Lancaster, SC, USA

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle started to bounce and was unable to be driven safely. There was no warning light illuminated. The vehicle was taken to marthaler Chevrolet of worthington (1627 oxford St, worthington, mn 56187), to be diagnosed. The contact was informed that the shocks needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 77,000.

- Worthington, MN, USA

Vehicle began riding rough at 58,000 miles. Due to covid we just brought the vehicle in to the dealer and found out the front shocks are leaking and the rear bags needn't to be replaced as they have holes in them they want 2900 to fix. Totally unacceptable there have been numerous complaints on this issue. This is a 70K vehicle with 68000 miles. I have owned 3 new Tahoe's in my life and never had this problem. If GM does not make this right this is the last GM product I ever purchase and if the dot does nothing about it they are just as bad.

Vehicle randomly brake occasionally while driving. Stabil trac error.

- Arivaca, AZ, USA

We own a 2015 Chevrolet Tahoe ltz and at 85,000 we had to replace both the front and rear shocks due to total failure. We paid a total of $3,200 for these repairs, as this was not covered under the power train coverage or our extended warranty. This is totally unacceptable by General Motors. A technical service bulletin is not sufficient. GM should issue a recall, as well as provide compensation to those who have had to cover this expense due to GM's very poorly designed suspension system.

Have a 2015 Chevy Tahoe ltz with only 35,000 miles on it. The vehicle started riding super rough, felt like it had no shocks when going over bumps or potholes. I took it to a local shop to have it looked at. Their mechanic said it looked like both rear shocks were leaking and needed to be replaced. I dd not believe them as the vehicle only had 35,000 miles on it. Took it to a certified Chevy dealer and they told me the same thing. Of course, they said it was not covered under warranty. Come to find out, after looking at several forums, this is a common issue with the magnetic ride suspension in the high trim package Tahoe and Yukon and yet GM will not cover them under warranty.

Has a problem in the suspension when you drive it jumps like an old truck. Recently replaced the front shock absorbers that we're covered by the warranty, but the problem still continues and it also feels too loose on the brakes. Another problem, recently went out to a store and when I reversed and I wanted to stop because a vehicle was coming, the brake pedal became hard as a stone and does not stop the vehicle no matter if you brake with all your strength the pedal becomes very hard and, now the problem is very constant.

At around 59,000 miles the rear suspension was very bouncy and a hard ride. Took to the dealership and they advised the rear shocks had extended out and stuck. Stated this is an ongoing issue with this year model of vehicle 2015 Tahoe ltz. The left front strut was also leaking. Was advised this system is controlled electronically to adjust the ride and have all four strut/shocks work in conjunction with each other to level out for a smooth ride. Well $1900 dollars for the rear installed and about $1000.0 for the front. So $3000 dollars later no covered under warranty on a vehicle with less then 60K miles is not good. Hell my first set of factory tires out lasted the mechanical shocks/struts. It appears Chevy has a issue they are not willing to fix or do a recall notice on. This could be a safety issue in vehicle handling in curves and hills?

- Braxton, MS, USA

Total strut failure at 58K miles; making car hard to maneuver. Dealership wants $1900 to fix the mag ride suspension, no powertrain coverage at all for this issue. Also, a bearing in the steering column has failed and there is no warranty coverage from that either.

- Midlothian, TX, USA

Suspension bounces so badly that the vehicle becomes unstable and difficult to control. Failure happened around 75,000 miles while traveling on the interstate and is a very common failure among the Tahoe, Suburban, and Yukon. GM has failed its customers by not covering the defective suspension under these vehicles. This will be the last GM vehicle that I purchase, I have had nothing but trouble from this car.
