TRANSMISSION UPSHIFT AND DOWNSHIFT TIMING IS WEIRD. PRESS ACCELERATOR TO GET MORE POWER TO PASS ANY VEHICLE ON THE ROAD AND TRANSMISSION VERY UNTIMELY UPSHIFT INTO HIGHER GEAR REDUCING THE POWER TO WHEELS. CREATES A DANGEROUS SITUATION SINCE LACK OF POWER REQUIRES PRESSING THE ACCELERATOR EVEN HARDER. ENGINE REACTS BY DOWNSHIFTING BUT POWER COMES TO WHEELS FEW SECONDS LATER AND OTHER CARS ON ROAD ALREADY CLOSE IN AND START HONKING.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Lexus RX 350h verdict →
