Hi Folks,
Long time Acura owner (CL, MDX. RDX), but just recently joined the forum.
I have a 2016 RDX and I just got the timing belt, water pump, tensioner, etc. replaced.
The mechanic drove it for 10 miles with no lights/issues. I pick it up and start it.... I immediately get all kinds of lights!
"Check Power Steering System"
"Check Emission System"
"Check AWD System"
(and you have the check engine light on, the power steering light on, the AWD light on, etc.)

Any thoughts on what is going on and how to correct it?
Thanks!

 

....and you can add "Check Hill Assist System" to the list of messages...
The engine shakes a little more than it did before at idle...but seems to drive OK....
Electric fans kick on/off like they should....Temp gauge normal....battery at 14.3V while running....

As far as check engine codes.... P0301 (Cyl 1 misfire), P0302 (Cyl 2 misfire), P0303 (Cyl 3 misfire), P0300 (multiple Cyl misfire)

 

If you are getting misfires on multiple cylinders it is very likely that the mechanic has missed the timing belt about half-tooth. If he had missing a full tooth on the belt, the car would not run properly at all. If I were you I wouldn't drive the car to prevent it from more damage. Take it back to him and tell him most probably he has missed it. He must take it out again and do it correctly free of any additional charge.

 

The parts changer missed one tooth on the bank1 camshaft . It is unacceptable to do the wrong job, take the money and send the custumer away with a faulty car, so force them put the timing belt correctly and never come back to these scammers.

 

If these lights all appeared upon pickup, what made you take possession of the car and (assumingly) drive it home?

I doubt the car was fine during a 10 minute test drive on his end, if he even did that. I guess there's also the possibility that the engine jumped timing upon the restart, as a result of some other installation issue or failure.

Either way, your mechanic ought to be 100% on the hook for the repair. Hopefully it is indeed a tooth off and that's the extent of it.

Just the other day in another post I was stressing the importance of running the engine off the battery for a few mins before reinstalling the timing covers, accessory belt, etc. to catch any issues before reassembling everything. He probably won't appreciate being told how to do his job, but then again, it's on him to get it right lol.

 

Thanks everyone!... A little update. The shop had the car hooked up to their main scan/diagnostic machine...had the car running and looking at data, etc...and they wiggled a main computer module connector ... a connector (one of many?) that you have to disconnect to get to the timing cover, etc...and they noticed an increase of mis-fires, etc....
They disconnected the connector....cleaned things up/inspected it....reconnected it...making sure it is on tight, etc....
They then went to all the connectors that they had to disconnect, etc....and made sure they were all good....and that has seemed to fix everything.
They drove it several times....turning it off for a bit....restarting it, etc...and no codes.
So, I think we are all good. We will see how it goes over the next few days.
They didn't charge me anything to fix it since it was their actions that caused the issue...

 

Glad it has worked out to a happy ending so far but honestly I have never heard a lose harness or connection cause cylinder misfier unless it's coil connector.

 

I know the stealer is expensive, but I always get them do the timing belt. My thought is they do virtually the same timing belt for all the v6's and know how to do them.

 

If I didn't have my own mechanic, I'd probably go the same route to play it safe.

 

After installing it all, did you do a dry run by cranking the engine over by hand in the proper direction (plugs removed) and then check to make sure everything is still lined up as it should be.
