Mercedes-Benz Problems

Electrical & Lights -- Verified

Instrument cluster displays tend to fail, especially the clock and gear indicators. Our technicians tell us the instrument cluster will require replacement to correct this issue.

Heating & Air Conditioning -- Verified

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

Suspension & Steering -- Verified

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Drive Train -- Verified

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Engine -- Verified

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Sensotronic Brake Control System May Default to Basic Hydraulic Mode

Brakes, August 8, 2005
RepairPal Expert Overview:

Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer. Dealers will install a bracket and replacement ground wire to the SBC pump unit on all affected vehicles. Additionally, dealers will inspect and replace the SSC pump unit in certain SL models. The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.

Mercedes-Benz Owners' Reviews

Since purchasing new in July 2011, I have had replaced under warranty the air shocks, front struts and, as soon as the parts arrive from Germany, the interior wood trim. In addition, I have had to replace the brakes/rotors at ~29,000 miles. Shame, really, because other than the suspension and brake issues, I really like the car. The engine is terrific - exactly what a normally aspirated V8 should sound, respond and drive like. The transmission is balky sometimes but, overall, works well. Not sure if the suspension problems are systemic or if I've just had bad luck. Given the frequency of repairs, however, I probably won't own the car long enough to find out.

Really I am not from Washington DC but Bishops Bridge NSW Australia.2325.
Only way I could get to say my piece.
My 2000 S430 is the most comfortable and luxurious car I have been in and I get chauffeured from airport to the Casino every second weekend in all makes of limos, that does not mean I am RICH.
I have difficulties in Australia with support as you can imagine there are comparatively few S430 Mercs on our roads.
I also have problems with the PLASTIC below the drivers seat that needs to be replaced. Where can I get a replacement, I don't mind paying freight from the USA. I may even visit Vegas again to pick it up. Love my Merc. Roger.

Love the car. 52,000 miles and rear brakes are just needing replacement. Minor issues with maintenance warning message that was solved by replacing sensor in driver's seat belt buckle, otherwise never a problem. Only complaint to this "luxury sports" vehicle is wishing for a bit more than stock 228 HP. Am trading for CPO 2103 to solve that issue.

Sadly, my family has experienced Mercedes Benz E320 and S430. I enjoyed the E320 way more than the S430. I feel both cars were poorly designed, the cost of repairs closely added up to the cost of purchase. I've owned a Ford and Toyota, and they've spent less time in the shop than the luxury cars. Problems ranged from: suspension and exhaustion hose issues(E320), power steering issues, electronic problems with the trunk and power windows, and the navigation system (S430). Mercedes Benz is just a status symbol, it's not a quality car. It's a joke to own one, but an expensive one at a combined $200,000 or so cost.

Purchased a used 07 in 07 (10 months and about 15k miles) and has been a nightmare since day 1. Engine, trans, A/C, electrical, steering, etc....you name it, it has gone bad on this car!!!! My third MB and could very well be my last. Tired of filling out surveys that ask you how clean the waiting room was when this POS breaks down weeks after repairs. Called MB Corp, no help at all. The level of arrogance at MB dealerships is the worst part. They act like its a privilege to get repair work done every few months and are rarely willing to bend on very expensive solutions.
