2000 Mercedes-Benz S Class Problems

What owners report

Owners of this model year most often describe two long-running problems: the instrument cluster losing its illumination or all of its gauges, and the air suspension letting the car drop onto its tires. Complaints arrive across a wide mileage span, from a few thousand to well over 150,000 miles, so these read as age- and wear-related failures rather than a single early-life defect. Several owners report that dealers told them their vehicle identification number fell outside the instrument cluster recall, and that replacement of the whole cluster was the quoted remedy.

1. 1
   Electrical system

   Instrument cluster goes dark or stops working

   • 37 complaints (46%)
   • median 86,000 mi at 7.8 yrs old (34 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2004–2011

   Owners describe the dashboard lighting flickering and then going completely dark, taking the speedometer, fuel gauge and other instruments with it, sometimes at highway speed. In some accounts turn signals, the trunk release and the remote key also stopped working at the same time. Complaints say dealers diagnosed an inoperable instrument cluster and quoted a full replacement, often around $1,700 to $2,400, and that the dealer or manufacturer declined coverage because the vehicle identification number was outside the interior lighting recall range. Reported from roughly 24,000 to 180,000 miles, with many cases in the 50,000 to 110,000 mile range and often noticed suddenly while driving.

   Recall 06V028000

   What to check: Turn the key and confirm every gauge and the odometer illuminate steadily, then watch for flicker after a few minutes of running. Ask whether the cluster was ever replaced and whether the interior lighting recall was performed or declined for this vehicle identification number.

   “2000 mercedes s-430 blower motor fuse failure with gauge cluster problem(all gauages got stuck with blower motor fuse explosion at same time, I had fixed the blower motor fuse that was covered by mb's recall, but not the gauge) mb dealer said that was just the gauge problem but that happened at same time when the fuse went out(I was driving at 60mph and suddenly, all gauge stopped and some light does not turn on anymore). …”

   NHTSA complaint #10100832, filed 2004-12, 64,000 miles

   “While driving our 2000 s-500 mercedes, we noticed the lights on the dash board begin to flicker on & off?! At certain moments, the lights which illuminate the gauges would actually go off completely briefly so it becomes impossible to read the infos on the dash board. We took the car to our mechanic whom informed us that there is actually a recall for the defect our car is experiencing under NHTSA's campaign id #06v028000. …”

   Suspension

   Air suspension lets the car drop onto its tires

   • 19 complaints (23%)
   • median 78,000 mi at 8.1 yrs old (16 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $650 (median of 5 quotes)
   • filed 2000–2011

   Owners report the car sitting very low, sometimes only a few inches off the ground, after being parked overnight or while driving, with tires rubbing the fenders and the wheel hard to turn. Complaints describe warning messages about the vehicle being too low, and dealers replacing air springs, the air compressor, the relief valve or installing a front suspension kit. Several owners say the same failure returned within months to a few years after repair. Mostly reported between about 45,000 and 150,000 miles, sometimes after the car sat unused for a period.

   Recall 07V263000

   What to check: Let the car sit overnight or for a few hours and check ride height at all four corners before starting it. Listen for the compressor running repeatedly and look for warning messages about the suspension, and ask whether air springs or the compressor have been replaced.

   “As I was driving my 2001 mercedes benz s500. My airmatic suspension fail and my car front went down as I was driving on the freeway. My tires start rubbing into my wheel well and started smoking. The problem left the front end damage. I had the problem fix by a mercedes dealership. Six month later the problem arise again. I don't drive the car for fear that I might get into an accident.”

   NHTSA complaint #10332676, filed 2010-05, 140,000 miles

   “I own a 2000 mercedes benz s500 sedan. While pulling into my parking space at home, the rear of my vehicle dropped to approximately 3 from the ground without warning, I had no idea why this happened. Had the vehicle towed to a mb dealership. They told me that the airmatic pump on the suspension system failed and needs to be replaced at a cost of $1500.00 us. I'm hoping there is no further damage to my vehicle. Thank god I wasn't on a highway when this happened.”

   Equipment

   Blower motor and fuse problems affecting heat and A/C

   • 8 complaints (10%)
   • median 88,000 mi at 8.1 yrs old (6 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2004–2010

   Complaints describe the heater and air conditioning blower stopping, sometimes with a fuse replacement restoring it for only a couple of days before it failed again. Owners report being told the blower motor or the blower motor regulator needed replacement, and some note the dashboard became very hot before the blower quit. Several mention the blower fuse holder and air conditioner blower regulator recalls and whether the work was actually done. Reported from around 50,000 to over 165,000 miles, with several accounts tying the trouble to warm-weather air conditioning use.

   Recall 04V227000Recall 00V141000

   What to check: Run the fan at every speed with the engine warm and the A/C on, and check the blower fuse and holder for heat damage. Ask whether the blower motor fuse holder and blower regulator recalls were completed on this vehicle.

   “Consumer received recall 04v227000 concerning blower motor fuse holder. Consumer took vehicle and the notification to the dealer, who refused to service the vehicle. Consumer later contacted the manufacturer and told his side of the story. Manufacturer would not assist or aide consumer.”

   NHTSA complaint #10104986, filed 2004-12, 53,000 miles

   “The contact owns a 2000 mercedes benz s430. The contact was driving approximately 45 MPH with the air conditioner activated when it stopped independently. The vehicle was taken to an authorized dealer where the technician informed the contact that the failure was caused by the blower motor regulator. The vehicle was repaired under NHTSA campaign id number: 04v227000 (electrical system: fuses and circuit breakers) yet the blower was not repaired. …”

   Air bags

   Airbag deployment complaints after impacts

   Mentioned in 4 of 60 sampled complaints

   A small number of complaints describe airbags deploying in a side impact where the vehicle had limited other damage, and one account describes airbags not deploying in a collision. Another reports sharp edges at the airbag seam after deployment were associated with facial injury. These accounts are few and vary in circumstances, and no common repair pattern emerges from them. Reported at mileages from about 53,000 to 181,000, in collision and curb-impact situations.

   What to check: Check that the airbag warning light comes on at start-up and then goes out, and have a shop scan for stored airbag fault codes. Ask about any prior collision repairs and whether airbags were replaced afterward.

   “Vehicle was hit by a semi-truck on driver side throwing drivers head and body into side door/glass windows. No air bags deployed! Car was severely damaged and was repaired by farmers insurance repair. Air bags were not replaced!!!! Driver suffered upper body trauma, particularly rib cage. Total air bag failure.”

   NHTSA complaint #10152519, filed 2006-03, 67,400 miles

   “A simple traffic accident which LED to an explosion car air bags, and injuring my daughter in the right eye, and loss of vision, because the driver's side air bag has sharp edges with the stitch on the surface of this to beat touching the passenger and his face.”

   Engine cooling

   Unexpected acceleration or stuck accelerator pedal

   • 6 complaints (7%)
   • median 51,934 mi at 8.7 yrs old (5 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2003–2011

   A few owners describe the accelerator pedal failing to respond or sticking, with reports of the engine revving to wide-open throttle and the car accelerating well beyond the intended speed until the ignition was switched off. Complaints mention the pedal valve sensor and pedal housing being replaced, and one account notes a mechanical safety device on the pedal had failed. Reported from about 46,000 to 138,000 miles, in ordinary driving conditions rather than a specific climate or season.

   What to check: During a test drive, press and release the pedal slowly at low speed and confirm it returns freely with no binding. Ask whether the pedal valve sensor or pedal assembly has ever been replaced.

   2 excerpts from owner complaints in NHTSA records

   “My major concern is the failure of my accelerator to respond. This could have easily been a fatal accident. I was beginning to enter the interstate and the accelarator simply failed to respond. Immediately got it to the shop and they replaced the pedal valve sender, pedal housing assembly,and input new codes for the pedal valve sensor. I was charged $361.03. Apparently many of the S Class cars have computer problems and I believe this model should be recalled to check pedal valve sensors and to install a saftey back up of some type. …”

   NHTSA complaint #10070712, filed 2004-01, 46,521 miles

   “The accelerator pedal on a 2000 mercedes benz s500 failed and became stuck to the floor causing the vehicle to reach speed in excess of 100m.p.h. Before the vehicle could be shut down by turning off the ignition. Upon a mechanics inspection, it was found that the mechanical safety device to prevent the pedal from becoming stuck had failed causing the pedal to go to wide open throttle and become stuck in that position.”

   NHTSA complaint #10381491, filed 2011-02, 138,000 miles

Buying note. Given the age of this model year, the practical priorities are the instrument cluster and the air suspension: budget for a cluster replacement if the gauges are dim or intermittent, and have the suspension checked for sagging and compressor noise. Ask for records of recall work on the instrument cluster, blower fuse holder and air conditioner regulator, since owners report coverage was sometimes declined or never performed.
