NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2005 Mercedes-Benz C230:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2005 Mercedes-Benz C230 owners say
Air bags all 50 →
The SAM system failed and car would not start !It took months to be diagnosed by 3 different mechanics! The message said quite often that the Air bags have been deployed !The dealer could not determine the issue! There have been various recalls on the Takata air bags stating my C230 2005 Kompressor is included in the recall over the last few years and when I put in the vin it says my car is not included! My mechanic said I should take it to the dealer before someone is killed. All I want now is to have these airbags replaced! Thank you [redacted]
Takata recall I was involved in an accident on jan 3, 2015 in my 05 mer Benz C230 the airbag exploded causing smoke and dust like particals I immedietly got off the car from that point on the car has been sitting tottalled I recently recieved a recall notification on 2/11/2016 I find it hard to believe this is the date this was figured out due to my settlement back in feb 2015 the insurance company submitted a market value report on my vehicle deducting 2 recalls from my car one being the airbag and this was a year before Mercedes even notified there customers. I have severe asthma and could not believe an airbag would contain the trash it didl. Its going on 2 years and my car is still sitting on lot unreparied with airbag inflated this is unbelievable I have documents showing I was complaining about the airbag before Takata even thought of mentioning there defect shame on you.
Engine & cooling
Vehicle began smoking on highway. No check engine or indicator of any fault codes. No previous coolant or oil leaks, or fuel leaks appeared to be visible or of issue. Vehicle had to be pulled over on side of highway as smoke began to became increasing with darker color from the engine bay, then making its way into the inner cabin Of the vehicle. Within a minute the full engine and front end of vehicle was engulfed in flames. Occupant was barley able to get out due to the vehicles dark smoke which caused disorientation for the driver. A good samaritan removed driver from vehicle and approximately 2 minutes later the entire car and cabin was engulfed in flames. Car was deemed a total loss with front end, cabin, and areas near the back seat/ window were burned to complete bare metal. …
As I was driving the car engine started vibrating and the engine light came on and the car engine stopped suddenly. The car was towed to my mechanic who diagnosed the timing chain cam sprocket teeth were worn out causing the timing chain to jump and destroy the engine. Research showed this is common factory defect with these engines since Mercedes used soft metal for the sprockets causing premature wear. I contacted Mercedes and they told me there is no open recall or class action suit for this year/model and recommended the car be towed to a Mercedes dealership for evaluation. My local Mercedes dealer informed me they require $200 fee to inspect the car and the replacement engine will cost me $10,000-15,000. The care is 13 years old and has 135,000 and out of warranty. …
