The engine upper magnesium intake manifold is spider cracked around several mating half bolts causing an engine emission warning light to illuminate for bank #2 lean code. I believe the part number for the upper intake manifold is P/N 17160-5G0-A00. 2017 Acura RDX with 84,000 miles. The Acura mechanic knew what the issue was right away stating that it’s known problem with the magnesium intake manifold, but Acura doesn’t have a recall.
If the vehicle goes over 65 mph the transmission light starts blinking on the dashboard.
Premature defective hydraulic timing belt tensioner similarly to the 2018 and 2019 RDX under recall. The seal in the tensioner prematurely aged causing hydraulic leakage making it unable to maintain timing belt tension. If the tensioner fail at highway speed causing the timing belt to skip leading to out of timing and major engine malfunction.
