There are 2 owner-reported suspension complaints for the 2018 Chevrolet Suburbanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The car was slowly making right hand turn when we heard a loud noise and stopped the car Once we got out, we saw that right wheel was completely torn out. We have videos and pictures. If it would happened on the higher speed, we would be dead. The car shop told us that they never seen anything like that in the past. Per their report, upper control arm broke off then the rest followed: lower control arm, ball joint, outer tie rod, poss inner tie rod, sway bar link, abs sensor connector. Consumer also learned from dealer that certain parts do not exist anymore and new ones are available.
THE AUTOMATIC AIR SUSPENSION HAS FAILED SEVERAL TIMES WHEN TOWING. THE SHOCKS LEAK, THE COMPRESSOR DOES NOT TURN ON, AND SOMETIMES, IF IT DOES TURN ON, THE BAGS DO NOT DEFLATE. WHEN THEY DO NOT INFLATE IT CAUSES DANGEROUS SAGGING AND SQUATTING. WHEN THEY INFLATE AND DO MOT DEFLATE AFTER TOWING THE REAR SUSPENSION IS VERY STIFF AND DANGEROUS TO DRIVE AROUND IN. I HAVE TAKEN MY VEHICLE IN OVER 5 TIMES TO FIX THE ISSUE AND CHEVY HAS BEEN UNABLE TO FIX THIS PROBLEM. THIS HAS BEEN ONGOING SINCE I PURCHASED THE VEHICLE IN 2018.
