Brakes
Re 2006 MERCEDES BENZ CLS500_ 211017_114326 On August 9, 2021, my brakes went out on the freeway when trying to dodge debris and other vehicles, when the brakes completely went out and caused me to run over major wood pallet debris, and scared for my.life to get to the far right lane to make it off te exit with no brakes whatsoever. and causing major under-carriage repairs. Rather than hit the cars on each side of me, all I could do at that point was get over lanes with no brakes, and make it off the exit before I killed myself and/or someone else. The damage done from the brakes going out, came to over $4000 in damage repairs to the under-carriage and left me without a vehicle for 45 days while in the shop This not only effected my income since the vehicle was used for Lyft,, but I also was evicted from my apt. …
No notice Brake Failure. Coming up to the corner of my sub-division before making a right turn onto a busy 4 lane road, Stepped on the brakes and nothing happened ! Swerved to the left to avoid hitting a jeep that was stopped in front of me also waiting for traffic to clear enough to make the right turn. My car traveled into the busy road, and its a Miracle I didn't get killed by a truck traveling 50 mph that might have T-boned my car on the driver side door. Car was beeping a loud noise and the instrument panel was lit up in Red with the following alarm. Reduced braking power, visit workshop. Car would not accelerate over 5 MPH with the alarm blaring. Luckily was able to turn on emergency flasher and pull over to the side without getting hit. This is the first time I ever had a car that when you stepped on the brakes nothing happened. …
