Engine temperature warning while driving (CX-60 3.3L Diesel)

[Philip082]

Hi Everyone,

Maybe someone has had a similar experience and has some knowledge about this: I was driving my CX-60 3.3l Diesel when i got this warning as shown below:

Excessive Engine Temperature Engine Output Restricted Temporarily.

The sequence of events were as follows:
- been driving for over 2 hours and everything was fine.
- I stopped for a toilet break and then when i continued the trip, within maybe 5 mins i got the above error.
- I slowed down and it went away as the car seemed to cool, then it came back when i accelerated up a hill.
The Coolant gauge was responding very fast, like if i reduced speed then the temp dropped and when i pushed the car it was increasing quite quickly. Aircon on then off didn't make any difference.
I then got an additional warning which said something like high coolant temperature so i stopped the car and turned it off.
I turned the car on and it was still showing it was hot. The fan radiator operated and i saw the the temp come down pretty fast while idling.
Got back in the car and the car drove perfectly for another 250km - no issues at all.
I tried to push the car and accelerate aggressively up a hill etc - the car was perfect, the coolant gauge didn't even flinch.

I not a 100% sure but it seemed like it was revving higher than it should be while it was overheating. I thought maybe i had bumped the gear flap and put it in manual but it was in D.
Car is 3 months old- less than 5000Kms.
I was not towing anything.
Outside temp was 23 degrees C.

If you have any ideas?
Could this be a Diesel Particulate Filter (DPF) cycle? But i never thought that could trigger a warning...
Best Regards
Philip

I have just had a similar issue, I was towing a caravan (well within towing limits) and was using cruise control set to 52mph. On inclines (not even hills) the car was dropping about 4 gears in order to climb at over 3000rpm (but was easily able to maintain speed if I went manual at between 2000 and 2500 rpm. I then started to get similar warnings although if accepted, they appeared to go away.

After less than 20 miles, the warnings increased and I pulled over. I checked the caraven - brakes were off, wheels did not feel warm so happy the van wasn't causing the issue. I sat for a few mins with engine off, tried restarting revving, no real issue with temp gauge sitting just over half way. I eventually decided to get off the dual carriage way as the layby didn't feel safe and slip road was only about 300 yds away - I made it up the slip road and turned slightly uphill towards a town but within about 1/4 mile, the alarm came back and car actually did go into "restricted output" mode. We pulled into a side road and called Mazda.

I opened bonnet and there was some evidence of water escape but the top up bottle was half full of dirty looking water. When assistance arrived, the chap had a look and stated there was no water in the engine (but no puddle on the floor). Car was taken to dealer who so far has not found anything which is not very reassuring and is now in dialogue with Mazda.

Only other comment is that front end of car was rebuilt after accident at end of last year - not sure if relevant but start to wonder if there is a cracked pipe or similar that only opens up when engine working hard (ish).

Car is 2 years old with 23k on clock. It towed the van happily last year doing a number of journeys of up to about 200m in a single run.

Doesn't help answer your question but may be it adds to it!

Anyone else had issues?
