I backed up into someone last week and cracked my passenger tail light. Have packing tape on it now which is good temporarily. The dealer said the assembly is $7xx.xx Canadian and with labour it's going to be $850 ish. Will check the local wreckers and also Lindsay. I like to get it fixed instead of having tape on it but almost $900 Canadian is crazy.
I got an OEM passenger side tail light housing from someone on the forum for $125 shipped. You can also get them on ebay for under $300USD but watch out for the non-OEM stuff, the lenses can have different diffusion patterns.
check ebay! I have seen several for around $100. Its not V specific either so when you search just search for a CTS tail light. But you probably already knew that.
I also have a power steering leak and dealer say it's from the rack's boot?? and the pressure hose. The steering does not make noise and no driveability issues except for the fact it leaks fluid and I have to top up every 2-3 weeks. Usually the level is at the low end of the container.
If there is no noise or driveability issues, is it safe to leave the repair. Quote of $2030 Cdn after labour.
