Bergen ave and jfk blvd jersey city when another driver from opposite direction crossed the yellow line,inner lane and hit me on the driver side full speed.the front ot side airbag did not inflate.he sped away.
We had a brake booster vacuum line that connects to the aluminum intake with a plastic fitting on a 2002 mercedes clk320 (173k miles) that got brittle and broke. Thankfully no one was injured or killed. I'm an ex-mechanic and have never seen plastic fitting used for the vacuum line to the brake booster on the engine.
There is too much rust on the vehicle! Car has never been in any accidents & has been washed & waxed regularly. Supposedly this is a very common issue with these cars which is disappointing.
They replaced the eis, then I get a call saying car still will not start. Now they say I need a esl(electronic steering lock) now my total jumped up to 2,200. I am so disappointed that all these problems can go out at the exact same time with no warning at all.
