2015 Chevrolet Tahoe brakes complaints
Page 8 of 8: complaints 191 to 196 of 196, newest first, as owners wrote them.
The brakes power assist fails after application of brakes in traffic or when reversing. When in heavy traffic situation and when applying light pressure numerous times, the brakes power assist fails and you have to apply very heavy pressure to the pedal to stop. Reversing, the brakes power assist fails almost immediately after initial brake application.
When applying the brakes my car doesn't stop 100% of the time. 1 time during highway slow moving traffic, 3 times backing out of my driveway (flat surface), 4 times when on incline/decline of road. When applying brakes, horrible chattering vibration comes from left front tire area, chatter vibration is felt in brake pedal. No matter how hard I apply the brake the car keeps going - it will finally stop, but I almost hit the car in front of me at the one highway occurrence, 2 times car finally stopped just before going over edge of property when pulling forward & backward to turn around in tight area. In each instance I am moving at a very slow speed. I contacted dealership, they told me I wasn't the only one calling about this happening but since I'm over 36,000 warranty they will charge me to ck it out, probably can't recreate the problem, said it was probably ABS but nothing they can do about that, suggested I find a dealership close to me whenever it happens again!
The brake pedal sits significantly higher than the gas pedal. When moving my foot from the gas pedal to the brake pedal, my foot gets caught on the back of the brake pedal.
