Limited data — recalls on file
NHTSA has just 28 complaints on file for the 1998 BMW 540i — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

“MULTIPLE COOLANT DEFECTS ON THE 1998 540. THE CAR HAS NOW HAD 3 RADIATORS, 3 THERMASTATS, WATER TUBE SEALS REPLACED TWICE, AND A WATER PUMP. THE COSTS HAVE BEEN OVER $3,500. THESE LEAKS ARE NOT JUST EXPENSIVE, THEY POSE A REAL DANGER TO CAUSING PERSONAL INJURY AND DAMAGE. THE FAILURE RATE IS KNOWN…”
“HANDLES (2 INCIDENTS) BROKE OFF IN THE NORMAL ACTION OF OPENING THE DOOR. NOTHING EXTRAORDINARY ABOUT THE SITUATION. SEEMS A VERY CHEAP COMPONENT ON A VERY SAFETY CONSCIOUS VEHICLE. *AK”
“I HAVE DRIVE STANDARD TRANSMISSIONS FOR OVER 40 YEARS, I HAVE NEVER HAD A CLUTCH PROBLEM UNTIL A PURCHASED A '95 540I (KNOW FOR POORLY DESIGNED CLUTCHES, PARTICULARLY THE PRESSURE PLATE). I BOUGHT THIS NEW '98 WITH HOPES THE PROBLEM WAS SOLVED, NO SUCH LUCK. IF I HAD THE FAILURE ON A MAJOR HIGHWAY…”
“STEERING WHEEL COLUMN ADJUSTMENT FAILS. MAKING ADJUSTMENT OF STEERING WHEEL AND VEHICLE SAFE TO OPERATE. STEERING WHEEL AND FRONT SEAT ADJUMENTS FAIL TO OPERATE FORCING OPERATOR TO DRIVE WITHOUT ABILITY TO ADJUST STEERING WHEEL OR SEAT. HAS FORCED ME TO ABANDON VEHICLE.”
The record is thin — 28 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
