Have you figured out the issue with the TPMS yet?

Have you checked your coolant level?

What codes did the mechanical get from the car? Does the starter spin went trying to start or is there complete silence? Does the horn work? The items that your mechanic replace should not prevent the car from starting but if something is amiss with the security system it would. Make sure the battery is fully charged and that all doors are locked. Then arm the system and make sure the key fob is not within 15 feet. Open the doors and try to start the car.

Engine mount....

Is your check engine light on? Your car should be throwing some error codes and that would be a good place to start. Have you checked the transmission fluid level?

Probably time to change the oil.

Welcome back, How much better do you think your 14 is over your 11?

Nice car. It's not in my sig but I have a 07 460L and it ride very well. Just as good if not better than my 98 which I gave to my brother. The AC not starting immediately is a symptom of the blower motor being broke or a fault in the system, https://www.clublexus.com/forums/ls-4th-gen-2007-2017/692514-a-c-malfunction.html

Pirelli P7 are a good alternative. There are lots of owners that swear by them.

Thta' That's great, How much did it cost if you don't mind me asking? They do have OE replacements on Ebay for about $6-700.

Thanks for the tip. Maybe this will help someone else in the future.

i have not heard of your particular situation but you need to have your mounts inspected if you have not done so already. Have a shop put your car on a lift and your problem should be obvious.

I believe the ECU controls the transmission as well. Did you use the exact replacement capacitors mentioned in the big thread on CL? Have you tried a couple of drain & fills of the transmission pan?

You most likely blew the main 80 amp fusible link.
