Hi guys, few questions...
2013 RRS SC, 90K Ml, but 10K on new engine installed spring 2019, less then 5K on new transmission fall 2019, both dealer installed.
1) Did any of you had to replace catalytic converters and if yes, at what mileage? I don't drive it like I stole it but not being shy to step on it either, sometimes I notice bad odor after hard acceleration, sort of rotten eggs like, do you think time has come for new catalysts? Is it doable DIY?
2) intermittently I get some kind of vibration around 70mph, feels like driving over slotted pavement. It comes and goes on its own, not a steering wheel but whole truck - floor as well, I am excluding unbalanced tires, not just because they are but this was carried over when I changed from summer to winter tires, both sets have their own rims.
3) I was driving from Wildwood NJ on Wednesday and rock chipped the windshield pretty bad on Garden State Pkwy, I have a glass coverage with Geico, anyone had similar issue? Did you go to the dealer to get replacement? are there aftermarket heated glass or the one from a dealer is a must/only option? How did you claim it? or dealer was able to do it for you?
Any info greatly appreciated.
Thank you.

Hey Roman,

1) No idea I'm afraid, but you can have a mechanic do a diagnostic to tell if it's a replacement jobby or if you need to run a cleaner through it.
2) Could be the harmonic balancer, either it was replaced incorrectly or it's developed a fault. Some more info here: What does a harmonic balancer do?
3) How bad is pretty bad? This happened on my Sport and unfortunately the chip went into the heating coil so I had to replace the entire windshield by a specialist. I don't know how cold it is by you, but if you have frost (or could put frost) on your windshield and turn on the heating coil you should be able to see if it works or doesn't in the area around the chip. If it works fine, you can get away with a partial replacement (again by a specialist) otherwise you're looking at a full new unit.

Hope this helps!

Hi. Thank you for your input.
1) I did not hear of "run the cleaner trough the catalytic converter" being widely advised - will do some research about that but if this is something you'd have to add to the fuel, my understanding is that fuel added cleaners tend to dilute, wash off oil film on cylinders and cause increased friction that results in piston side walls being scored as well as premature wear of combustion chamber components. I my vision, if I go as far as physical inspection, for as much as PITA it is going to be - unbolting Cats from exhaust manifold, I might as well have new CATs ready and replace them if inspection shows the old ones had failed.
2) Thank you - I have followed and read about the Harmonic Balancer , It is a part of brand new engine that I had installed 10 or so month ago. It is possible that maybe something is defective there but I tend to think that chances are slim.
3) Sir, I think we're having some misunderstanding, the windshield is one solid piece, how "get away with partial replacement" can take place regardless of severity of a damage?

My apologies! I was thinking of a diesel particulate filter, not a catalytic converter! Been a long week :)

Regarding point 3, the windshield is 3 layers: Glass, wire, Glass. If the chip has only damaged the surface glass, you can get away with only having that layer replaced. If it hits the wire, you need a new unit.

no check engine light but exhaust smells really bad at start up and when driven enthusiastically.

Thank you for your input but Sir, the whole engine is brand new factory engine, replaced spring 2019 with 10k ml on it. As far as I know it did not come with spark plugs and injectors but I assume it did come with PCV. Also, wouldn't PCV issue be accompanied by black smoke as failed PCV usually introduce oil in to intake?

I will go "all in" on these issues. Ordered both CATs, both driveshafts with all new bolts and nuts.
I had front wheel hubs replaced and front Sway Bar replaced in 2018 by the dealer so I can assume they're OK
by the process of illumination, what else is there? CV Joints? All boots are good - not sure if that is 100% reassurance that there is no wear, but also there aren't many complaints about failed CV Joints either... Will order differentials and transfer case oils as well, so when Rover goes on lift, I might as well hit as many points as I can.

Fuel pressure can cause black smoke
