Owners have filed 75 complaints
about the 2003 Mitsubishi Diamante with NHTSA between 2003 and 2019.
The largest single group is the windows, mirrors & wipers.
Across this model's run it ranks 7 of 10 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 63
Against the median year of the Mitsubishi Diamante. 50 means typical for this
model; 100 means roughly double.
Severity — 14
2.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 45
27% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2003 compares with every other Mitsubishi Diamante
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.
Odometer readings owners gave when they filed. About half of all
complaints include one.

NHTSA crash tests
The agency crash-tested this model year itself. These are its own
photographs and star ratings.
These stars come from the pre-2011 crash test programme. NHTSA
rebuilt the programme for the 2011 model year and states that
ratings either side of that change are not comparable — so do
not read these against a 2011-or-newer car's stars.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2003 Mitsubishi Diamante
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

I HAVE A 2003 MITSUBISHI DIAMANTE LS WITH 71677 MILES ON IT ALL OF THE SUDDEN MY HUSBAND (THE PRIMARY DRIVER) TELLS ME THAT EVERY TIME HE GETS OUT OF THE CAR HE FEELS LIGHT HEADED AND NAUSEOUS. DAYS LATER THE FRONT WINDSHIELD STARTED FOGGING UP WHILE DRIVING AND AFTER TURNING THE CAR OFF (WHETHER IT IS WARM OR COLD OUTSIDE) I GOOGLED WHY WOULD THIS HAPPEN AND HAVE SPOKEN WITH A FEW MECHANICS AND THEY ARE TELLING ME THAT IT IS THE HEATER CORE GOING OUT, AND THAT THE REASON WHY MY HUSBAND IS GETTING LIGHT HEADED AND NAUSEOUS IS BECAUSE THERE IS ANTI-FREEZE COMING INTO THE INTERIOR OF THE CAR WHICH IS VERY DETRIMENTAL TO YOUR HEALTH. I HAVE READ A TON OF COMPLAINTS ON DIFFERENT WEBSITES AND THEY ALL SAY THE SAME THING. I CONTACTED MITSUBISHI CORPORATE TODAY AND SPOKE WITH A [XXX] IN CUSTOMER SERVICE AND EXPLAINED TO HER WHAT WAS GOING ON AND ASKED WHY MITSUBISHI HAS NOT DONE ANYTHING ABOUT THIS. FIRST BECAUSE OF THE HEALTH IMPLICATIONS, SECONDLY BECAUSE OF THE SAFETY ISSUE OF THE WINDSHIELD FOGGING UP WHILE YOU'RE DRIVING TO WHERE YOU CAN'T SEE AND THIRDLY THAT FROM READING THE COMPLAINTS, THE HEATER CORE IS RIGHT ABOVE THE COMPUTER IN THE CAR SO IF THE HEATER CORE IS LEAKING ANTIFREEZE, IT COULD FRY THE COMPUTER AND CAUSE A POSSIBLE CRASH IF THE CAR WERE TO STOP SUDDENLY. SHE SAID THAT "SEEING THAT I HADN'T HAD THE CAR INTO A DEALERSHIP IN THE LAST YEAR THAT THERE IS NOTHING THEY CAN DO ABOUT IT". I TOLD HER THAT IT JUST STARTED AND WHAT WAS I SUPPOSE TO DO, LOOK INTO MY CRYSTAL BALL AND KNOW A YEAR AHEAD OF TIME THAT THE HEATER CORE WAS GOING TO GO OUT. THIS IS LUDICROUS! ! ! MITSUBISHI KNOWS THAT THIS IS A SERIOUS ISSUE AND ARE NOT DOING ONE THING TO FIX IT (BY ISSUING A RECALL) WHERE DO WE DIAMANTE OWNERS GO TO GET SOME HELP? DO WE NEED TO FILE A CLASS ACTION LAWSUIT AS THAT SEEMS LIKE THE ONLY WAY A FIRE IS GOING TO GET LIT UNDER THEM (CORPORATIONS TEND TO ACT IF IT MEANS LOSING TONS OF MONEY) THE CAR CAN'T BE DRIVEN AND I'M STILL PAYING ON IT.

IT HAS LESS THAN 50,000 MILES ON IT AND IT HAS SUDDENLY STARTED SPEWING A LIGHT FILM ON THE INSIDE OF MY FRONT WINDSHIELD SO THAT I CANNOT SEE WELL...AND NOT AT ALL WHEN I AM HEADED INTO THE SUN.

AFTER RESEARCHING MY PROBLEMS I'VE NOTICE WELL OVER 1000 POSTED VIA INTERNET FROM OTHER MITSUBISHI DIAMANTE OWNERS HAVING THE SAME ISSUE. ITS HARD TO BELIEVE THIS VEHICLE HAS NOT BE RECALLED. THERE ARE GREAT RISKS OF INHALING ANTI FREEZE WHICH IS SEEPING INTO THE CAR THROUGH THE FLOOR BOARDS AND VENTS.

I WAS TOLD THAT THE CAR'S HEATER CORE LEAKED ONTO THE COMPUTER WHICH CAUSED THE TRANSMISSION RELAY TO SHORT OUT DO TO THE COMPUTER FAILING. THE COMPUTER WAS STILL UNDER WARRANTY AT 78,000 MILES BUT I STILL HAD TO PAY FOR THE NEW COMPUTER SYSTEM BECAUSE I WAS TOLD THAT IT WAS THE HEATER CORE THAT CAUSED THE COMPUTER TO FAIL. THIS IS SUCH A POOR DESIGN! THE COMPUTER SHOULD HAVE BEEN PROTECTED IN SUCH A CASE...FUNNY THING IT IS NOW THAT I HAVE HAD TO REPLACE A HEATER CORE, A COMPUTER AND A TRANSMISSION RELAY AT A CUT WRENCHING COST OF $3,675.58. I WROTE A LETTER TO THE PRESIDENT OF NORTH AMERICA MITSUBISHI THAT THE HEATER CORE SHOULD BE A RECALL BUT TO NO AVAIL.
