What 2003 GMC Yukon Denali XL owners say
Most recent owner complaints, unedited.
There is no warning code for the hydraulic brake booster when it starts to go bad that shows up on the ABS/odb scanner. You will be driving and all of the sudden your steering gets stiff, the brake pedal is hard to press and you can't stop as good as your used to in the vehicle. This issue can cause accidents if someone stops suddenly in front of you.
The stability control warning has come on several times on my vehicle. The brakes do not work, as you have to push all the way to the floor and sometimes it takes time before the vehicle stops. I have had brake lines repairs and the problem still is there. We cannot use vehicle until the issue is resolved. Our mechanic advised us to file a complaint on this issue because it is an active issue with gmc denali yukon's for years. We need assistance to have this resolved to use our vehicle.
I let my freind take vehicle and she said when she braked the pedal went to floor.she was half mile away and made it back .I looked at level in master cylinder and had to put fluid in.noticed brake fluid on the undercarrige which LED me to rusted brake line up front.
I was driving with my 14month old baby in the car and all of a sudden I had no brakes at all. My parking brake couldn't stop me either so I put the car in neutral and then forced it into park so I didn't crash. The brake lines are completely corroded and I didn't have any notice or idea until the brakes were already gone.
Just bought car electrical has been acting up for a while now (30 days) and now dash has gone out sunroof wont open pr close and driver side passenger window doesnt work auto store wont fix or take back car
A dog ran out in front of me I applied my brakes and the pedal went to the floor had it checked at bale chevrolet in little rock ark. Wanted to charge me 6800.00 to repair had it towed back to il. Where I live that cost was 500.00 besides 200 miles that was covered by aaa I,m a 62 yr old woman had my grandchildren with me in little rock ark this experience was the scariest time in my lifetime no warning just all of a sudden no brakes in the worst traffic ever. The money spent on this trip was very expensive not to mention the stress.
Vehicle went into reduced engine power and stabiltrak warning light came on. Reduced speed from 60 to 10mph. Now occurs on a regular basis.
Brake pipe blew out from corrosion... Light front damage to gmc and rear end damage to car in front from lack of braking power.
Vehicle powers down without any pattern, rhyme or reason. It will do it at 5 MPH, and at 55 MPH, when driven a lot, and when not. Reduced engine power light turns on, vehicle suddenly slows to 25 MPH max, steering becomes hard, brakes too. Then will totally shut off immediately. I have replaced the battery, throttle body assembly and wiring harness twice. Fuses, fuel pump and filters, oil, and everything else as recommended. It put me in the ditch. It stranded me in the center of a freeway in winter. When it sits for a while, it resets, only to do it again. T/c light turns on also. I found out that I can manually reset the reduced engine power for a few moments (to get out of the center of the road) by turning the ignition switch on and off very fast. It is a extreme safety hazard! I haven't driven it in months due to absolute fear for my life. When its in reduced engine power mode, I can't get it to go above 25, and going up hills can't go above 5mph. If I am pulling a trailer, it starts to go backwards. This thing is going to kill someone! Please help
